Discrete Solutions for EV Charging

When driving an EV, you will be impressed by its surpassing acceleration. More controversial discussed are the environmental aspects. Clear is that there is no pollution at the place where you drive. But if electricity for re-charging the battery is generated in the traditional way, the problem is just shifted to another place. New concepts deal with the usage of EVs for energy storage of fluctuating solar and wind power. Wall boxes or, even better, wireless charging systems at home and in companies could ideally serve such concepts.

All kind of EV charging stations can be easily realized by using cost-effective, widely available discrete power components. At low power systems they can be used to build the entire power stage, while at high power charging stations they are mainly used for auxiliary functions and controls.

Our latest flyer introduces a broad range of discrete power semiconductors from Bridge Rectifiers over Fast Efficient Diodes and MOSFETs to Schottky Rectifiers. It further includes state-of-the-art components used for control and protection purposes. They allow design engineers to develop cost-effective and energy-efficient solutions for any EV charging system.

The SRL23 is a high current Schottky diode in the tiny PowerSOD-323/DO-219AD package and measures 2.5 mm x 1.25 mm. It thus requires just 3.1 mm² on the printed circuit board.

This device is optimized for high frequency and high power density applications. It features a repetitive reverse voltage of 30 V and nominal forward current rating of 2 A. Having smaller dimensions, low height profile and large cathode-sided leads these part enable the design engineers to increase power density and save space in compact electronics. The low forward voltage characteristics allow for energy efficient solutions for applications like battery chargers, power supplies, set-top boxes, smart meters, any kind of smart home devices and much more.

Features:

• Ultra-small and low profile PowerSOD-323 package.
• Requires only 2.5 mm x 1.25 mm of board space
• Just 0.6 mm of device height
• Forward current 2 A and 30 V repetitive reverse voltage

Linear voltage regulators are simple and cost-efficient devices, for generating stable output voltage from a wide range of higher input voltages. With their simple 3-pin internal configuration and small package dimensions, they enable the designers to easily use them in various linear circuits covering a broad range of applications.

Our new linear voltage regulators are designed for high performance operation. Applications include medium power general-purpose consumer and industrial circuits such as DC/DC converters, battery chargers, LED drivers and µController (MCU) circuits.

Linear voltage regulators are used in sensitive applications and complex circuits, requiring stable supply voltages, low to medium current capabilities and low noise. You can find all the information also in our new flyer.
