P011xx
Sensitive high immunity SCRs up to 0.8 A
Features
■IT(RMS) up to 0.8 A
■VDRM/VRRM 400 and 600 V
■IGT from 0.5 to 25 µA
Description
Thanks to highly sensitive triggering levels, the
P011xx SCR series is suitable for all applications
where available gate current is limited, such as
ground fault circuit interruptors, pilot circuits in
solid state relays, standby mode power supplies,
smoke and alarm detectors.
Available in through-hole or surface-mount
packages, the voltage capability of this series has
been upgraded since its introduction and is now
available up to 600 V.
