Three-terminal output device for a solid state relay
« on: May 06, 2017, 07:18:48 AM »
Hi,

Has anybody seen a solid-state relay with BJT output device which has a base lead available (similar to 4N25 opto-coupler but an SSR not an opto-coupler)? What would be the applications of this terminal being available?

Thanks in advance!

In the first place, BJT is not suitable to use for a solid state relay and a SSR without opto-coupler and base lead available for driving, ain't that just a single and all alone BJT transistor then? :)

What is it you are trying to build or design?

Are you thinking of an IGBT?  (Insulated Gate Bipolar Transistor)?
