You can find them at many filling stations: Fully automatic tools to fill up flat tires. You just type in the required air pressure, connect the tube to the car's tire, and press a button. All the rest is done automatically. The compressed air is generated by an electric air pump and stored in a tank. The pump motor is driven by full electronic drive inverters, allowing precise and energy-saving airflow control. Depending on the size and power rating, the compressor is either operated on single-phase or three-phase mains.

Diotec's DIW040F135 is a 40 A / 1350 V IGBT used in the drive inverter circuit. It offers a fast switching characteristic and low saturation voltage, both for saving energy and improving efficiency of the inverter stage. An integrated freewheeling diode helps to save board space and assembly costs. The part comes in standard TO-247 package for easy heat sink mounting and effective cooling.

With the help of solar panels, you can travel on the water even more independently and improve safety at sea. Electronic systems play an important role in navigation, steering, radar detection, marine communications, and everything from climate control to marker lights. Like in a car or truck, these electronics are supplied from a 12 V or 24 V battery, charged from the combustion engine. But what if that engine fails? Then the battery will be discharged quite quickly, which is a nightmare when you are in the middle of the Pacific Ocean. It is good to know that the solar panels can still charge the battery in such a case.

The ER1D-AQ by Diotec Semiconductor is a superfast recovery rectifier, qualified to AEC-Q101 and assembled in a DO-214AC/SMA package. It is an output rectifier in a maritime DC/DC converter, transforming the 24 V battery level to the 5 V required from the onboard electronics. Its superfast switching time reduces power losses, the 200 V of reverse voltage provides a high safety margin, and the qualification according to AEC-Q101 ensures outstanding reliability.

This board is used to demonstrate the functionality of the LDI55-ADEEN linear regulator. It has wide input range up to 50V, low-dropout (LDO) voltage regulators with enable function and provides up to 1A of output current. Only two small ceramic capacitors are needed to implement the linear regulator solution. The features of low quiescent current as low as 3 µA to 5µA and almost 0.5 µA disable current is ideal for powering the battery equipment to a longer service. Simple device measurements such as line and load regulation, dropout, can be demonstrated with just a single voltage source, a voltmeter, an ammeter, and load resistor.

Remote opening of the garage door is a feature no driver wants to miss anymore, especially on rainy days. But also, bikers or cyclists enjoy the comfort of opening the garage without getting off the bike, which is a time-saving benefit to daily routines. Up-to-date systems communicate via Bluetooth with smartphones or smartwatches. As soon as the user presses the "open" button on the app, a signal is sent to the garage door system, which in consequence starts the electric motor of the door opener. Smart home systems like KNX offer wired or wireless devices where the garage door is opened remotely using voice commands or again by smartphone app.

The garage door system stays on standby 24/7, and though the power demand in this mode is rather low, the circuit has to fulfill rules like "ENERGY STAR," allowing for a maximum of 0.5 W in standby. When the electric motor starts to open or close the door, the peak current demand is rather high, requiring a powerful rectifier bridge at the AC input of the drive circuit. The GBI25J-LX elegantly combines both: The typical forward voltage drop of the four rectifier diodes is 0.90 V, saving energy during standby operation. Repetitive peak forward current can reach up to 60 A, powerful enough at any time when the motor starts to pull the door. Its single-inline case outline allows for easy heat sink and printed circuit board assembly.
