## Small signal Schottky diodes 

## **Datasheet** - **production data** 

## **Description** 

The BAT30 series uses 30 V Schottky barrier diodes encapsulated in SOD-523 or SOT-323 packages. 

This device is specially suited for switching mode applications needing low forward voltage drop diodes. 

## **Features** 

- Very low conduction losses 

- Negligible switching losses 

- Low forward and reverse recovery times 

- Extremely fast switching 

- Surface mount device 

- Low capacitance diode 

- ECOPACK[®] 2 and RoHS compliant component
