## **Features** 

- ST advanced rectifier process 

- Stable leakage current over reverse voltage 

- Reduced leakage current 

- Low forward voltage drop 

- High frequency operation 

## **Description** 

The device is based on a proprietary technology that achieves the best in class VF/IR trade-off for a given silicon surface. This 100 V rectifier has been optimized for use in confined casing applications where both efficiency and thermal performance matter. With a lower dependency of leakage current (IR) and forward voltage (VF) in function of temperature, the thermal runaway risk is reduced. Therefore, it can advantageously replace 100 V Schottky diodes.

## **Notes:** 

- (1)Pulse test: tp = 5 ms, δ < 2% 

- (2)Pulse test: tp = 380 µs, δ < 2% 

To evaluate the conduction losses use the following equation: 

P = 0.415 x IF(AV) + 0.019 IF[2] (RMS)
