Wireless Charging Station for Your Mobile, Watch and Earplugs Powered by MOSFET DI048N04PT

The 3-in-1 wireless charging station features two chargers and 18 copper coils, ensuring fast and efficient charging for all your devices. It stands out with its ability to simultaneously charge a cell phone, a smartwatch, and earplugs. Designed to work even with device cases, it may only face interruptions with particularly thick cases or obstructions like a handle.

Diotec's DI048N04PT N-channel MOSFET comes in a space-saving QFN3x3 package but still delivers a Drain current of 48 A at a Drain-Source voltage of up to 40 V, making them perfectly suited for small yet powerful wireless charging applications. With its very low on-state resistance of less than 7.5 mΩ, it ensures cool operation even in the hottest wireless charging environments.

Inductively Charged Electric Toothbrush Equipped with Z1SMA47 Zener Diode

This intelligent electric toothbrush is designed for convenience and efficiency, perfect for your travel needs. With extended battery life, you can enjoy hassle-free use wherever you go. Fully charged battery lasts minimum two weeks, enough for an entire holiday trip.

Its waterproof design provides protection against water splashes, a must in bathroom environments. A key for that important feature is the inductive charging system, consisting of a primary coil in the base and the secondary one in the toothbrush.

Diotec's Z1SMA47 zener diodes are installed in the charging base. The input circuit is as simple as clever: It is a capacitive power supply and an oscillator supplying the transmission coil. Part of the power supply is the Z1SMA47, a 1.5 W / 47 V Zener in a DO-214AC/SMA package. This device allows to meet the EU and US "Energy Star" requirement of less than 1 W of standby power. As such, you can keep the socket permanently connected to the mains, without the need to plug and unplug for every new charging cycle.

MOSFET PDU Power Delivery Unit 100V | 80A

This board is used to demonstrate the use of the Diotec DI280N10TL in a high-power delivery unit. It is capable of switching up to 80 A at 48 V in both directions. This makes it ideally suited for battery systems which need not only to supply power, but also to receive during the charging cycle. Current, Voltage, temperature and operating mode is displayed on an OLED display. Various other Diotec parts such as LDOs, small signal MOSFETs, Rectifier Diodes, Zeners and ESD protection diodes is also used on this module.

Electric Yachts – Emission-Free Aquatics, Motor Drive Powered By the SiC-MOSFET DIF120SIC022-AQ

The large number of yachts operating in coastal areas calls for a reduction of both combustion emissions and noise pollution. The solution is an all-electric propulsion system that is emission-free, produces less noise and vibration, and therefore offers cleaner, more efficient navigation. The acceleration, speed, and efficiency of these electric propulsion systems offer an unparalleled cruising experience and set new standards in marine design and technology.

The SiC-MOSFET DIF120SIC022-AQ by Diotec Semiconductor is the perfect device for highly efficient boat drive inverters. It offers 1200 V of Drain-Source voltage and 85 A of continuous Drain current at 100°C case temperature. It comes in a 4-pin TO-247 package, equipped with a Kelvin source contact. This allows for high-speed switching with reduced power losses and high-reliable operation. It is perfectly suited for high-voltage batteries known from electric cars and is now being adopted by the naval sector.

High Efficient Electric Water Pumps Are a Key Factor in the Agricultural Sector

Sunshine and warm weather are perfect to stay outside. But when it comes to agriculture, and thus the way to create our daily food, long-lasting hot and dry periods lead to partial or even total losses of the crop. Artificial lakes are a good way to store rainwater during wet seasons and to distribute it onto the fields when required. Easy to be done in mountainous areas, where simple water channels can be used.

In plain countries, technical support is required for field watering. In the early days, windmills and later diesel engines drove the pumps. Nowadays, electric motors do the job. A perfect combination is electric pumps together with photovoltaic (PV) panels: Watering is needed when the sun is burning, and exactly then the PV panels create free energy. The electronic control of these pumps is a prerequisite for high motor efficiency and reliability, minimizing downtime and maintenance, but also energy consumption.

The fast-switching IGBTs DIW040F135 by Diotec play an essential role in the drive inverter of these pumps. Its low switching times predestine them for use in high-speed switching applications like this. They come in a TO-247 package for easy heatsink assembly and in consequence for a low operating temperature. The high Collector-Emitter voltage of 1350 V and the Drain current of 40 A make the parts perfectly suited for medium-power water pump drives.

Portable and Waterproof Speakers – Supplied By the Adjustable LDO LDI55-ADEEN with Enable Pin

Waterproof speakers with Bluetooth connectivity are the perfect companion for all kinds of water sports and outdoor leisure. The built-in rechargeable battery gives plenty of playback. Another plus is its small size, so you can carry it anywhere you want. And if an unforeseen spume sprays some water across it – don't worry, it's fully protected!

The LDI55-ADEEN linear voltage regulator from Diotec is an adjustable low dropout voltage regulator (LDO) that delivers an output voltage between 1.3 and 15 V with a tolerance of +/- 2 % and a very low dropout voltage. It is packaged in an ESOP-8 case outline with a heating pad, which allows for an output current of up to 1000 mA. Further benefits include low quiescent current, thermal overload, and short circuit protection. When the electronics require standby mode, the LDO can be easily switched off by the enable pin. This makes it a perfect match to supply portable devices like a waterproof outdoor speaker!

Need a Charge? SiC MOSFET DIF120SIC053-AQ with Kelvin-Source Speeds Up the Process

The DIF120SIC053-AQ is a Silicon Carbide MOSFET by Diotec Semiconductor, dedicated to charging systems of electric vehicles. It features a high reverse voltage of 1200 V combined with an extremely low on-resistance of just 53 mΩ. It has a fourth, so-called Kelvin Source contact, which offers several benefits: Speeding up turn-on time, saving power losses, lowering faulty switching during turn-off, and allowing for easier driver circuitry.

The part comes in the TO-247 case outline for easy heat sink assembly and the possibility to operate in parallel for higher power demands. Typically four of these MOSFETs are used in an H-bridge configuration for the bidirectional input circuit, and two in the step-up/step-down converter for charging or discharging the battery. That could be either stationary or as an on-board charger since these parts are fully AEC-Q101 qualified.
