Hi guys,
I am trying to drive a 2n3055 with a CNY75B optocoupler. The output from the opto on the spec sheet suggests 50ma current. The minimum current to drive the 2n3055 seems to be 100ma. The problem I am seeing is a "flaky" output from the 2n3055 - erratic. Will I need to add a coupling stage to control the 2n3055, or could I upgrade to a high current output opto?
Pretty basic I know, just trying to work it out.
Thanks
