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.
