Description
Thanks to highly sensitive triggering levels, the 0.8 A P0109DA SCR thyristor is
suitable for all applications where available gate current is limited.
This device offers a high blocking voltage of 400 V, ideal for applications like
interrupters circuits.
The P0109DA is available in through-hole TO-92 package.
