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

P0109AL属于分立半导体产品 > 晶闸管 - SCR。意法半导体（ST）集团制造生产的P0109AL晶闸管 - SCR可控硅整流器 (SCR) 是三端子器件，其功能类似于整流二极管，并具有在施加控制信号前阻止正向电流流动的附加功能。SCR 最常用于控制交流市电，也称为晶闸管，但后者有时也适用于其他相关器件。
