Thank you, I realised the triac death at pressing off button as low wattage resitor start to burn but at turning on/ nothing happened (when install a R-C snubber circuit). That would means with initial test, no snubber circuit, the triac died on switching off High Capacitive load (02 adapters...
Sorry for replying late, U5,U5 is the two SN74LVC1G3157DBVR to act like a swaping switch so that turning off the relay by Touch module or by MCU can toggle the relay. This is a way of applying stair case switch to the relay.
My second version has a schematic problem (Connecting to Pin4 instead...
Hi Everyone,
I found a thread asking on inductive load for Triac can kill the triac with clamping voltage, however, the thread is no longer open so let's me make a question here and hope you will be so kind to help me!
I made a relay using a BTA16-600BRG with MOC3020. The relay working find with...
