CPC1972G

Littelfuse IXYS · Solid State Relays (Triac Output) · DIP-6

CPC1972G from Littelfuse IXYS, in a DIP-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 LED+ input LED anode (positive) input. Forward-biased with typical IF = 5 mA (VF ~1.2 V) to activate the AC output. Absolute maximum input current 50 mA continuous.
2 LED- input LED cathode (negative) input. Reference return for the control-side LED; maximum reverse input voltage 5 V.
3 NC unconnected No internal connection. Leave unconnected or tie to non-critical net.
4 AC_LOAD passive AC load output terminal (SCR output). Bidirectional AC switch terminal, rated 550 Vrms operating / 800 Vp blocking, 250 mArms continuous load current, 3 Vrms on-state drop. Pair with pin 6 to switch the AC load.
5 NC unconnected No internal connection. Leave unconnected or tie to non-critical net.
6 AC_LOAD passive AC load output terminal (SCR output). Bidirectional AC switch terminal paired with pin 4; zero-cross switching keeps first-half-cycle turn-on <=20 V to minimize transients.
