BAS70

Low capacitance, low series inductance and resistance Schottky diodes

Features

■Very low conduction losses

■Negligible switching losses

■Low forward and reverse recovery times

■Surface mount device

■Low capacitance diode

■Low resistance and inductance

Description

The BAS70 series uses 70 V Schottky barrier

diodes packaged in SOD-123, SOD-323, SOD-

523, SOT-23, SOT-323, SOT-323-6L or SOT-666.

These diodes are specially suited for signal

detection and temperature compensation in RF

applications.
