TECHNICAL SPECIFICATIONS OF SMALL SIGNAL SCHOTTKY BARRIER DIODES
VOLTAGE - 30 Volts
CURRENT - 0.2 Amperes
FEATURES
* For general purpose applications
* This diode features very low turn-on voltage and
fast switching. This device is protected by a PN
junction guard ring against excessive voltage,
such as electrostatic discharge(ESD).
