Description
Thanks to highly sensitive triggering levels, the
0.25 A P0109AL SCR Thyristor is suitable for all
applications where available gate current is
limited. Its high immunity makes it ideal for high
electric noise circuits.
The surface mount SOT23-3L package allows
compact SMD based designs for automated
manufacturing.

Features
 IT(RMS) 0.25 A
 Low 1 µA gate current
 High noise immunity 100 V/µs
 ECOPACK® 2 compliant component

Applications
 Standby mode power supplies
 Smoke detectors
 DC 24/48 V proximity sensors
 Gate driver for large Thyristors
 Overvoltage crowbar protection
 Capacitive ignition circuit
