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, SOD523, SOT-23, SOT-323, SOT-323-6L or SOT-666. These diodes are specially suited for signal detection and temperature compensation in RF applications.
