HIGH EFFICIENCY SWITCHING AND 

ULTRA LOW LEAKAGE CURRENT SCHOTTKY DIODE **MAIN PRODUCT CHARACTERISTICS** A K **IF(AV) 1 A VRRM 23 V IR 25°C(max) @ 15V 12 µA Tj (max) 150 °C FEATURES AND BENEFITS** ■ Low conduction losses ■ Very low reverse current **SOD-323** ■ Negligible switching losses ■ Low capacitance diode == ■ Low forward and reverse recovery times ■ Extremely fast switching 

- Surface mount device 

## **DESCRIPTION** 

The BAT20J is using 23V schottky barrier diode encapsulated on a SOD-323 package. This is specially suited for switching mode in mobile phone and PDA power management applications or LED driver circuits (step up converters).
