GAQY216E from SUPSiC, in a DIP-4. 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_A	input	LED anode of the input opto-coupler. Drive with forward current IF between 5 mA (min) and 30 mA (max), typical 7 mA. VF ≈ 1.2 V typ, 1.5 V max at IF = 10 mA. Absolute max continuous IF = 50 mA.
2	LED_K	input	LED cathode of the input opto-coupler. Return path for LED forward current IF. Maximum LED reverse voltage VR = 5 V.
3	OUT1	passive	Output MOSFET terminal (drain of one of the back-to-back MOSFETs forming the AC/DC solid-state switch). Load voltage VL up to 600 V (AC peak or DC) between pins 3 and 4; load current IL up to 0.08 A; Ron ≈ 35 Ω typ, 70 Ω max. Polarity between pins 3 and 4 is arbitrary (AC or DC).
4	OUT2	passive	Output MOSFET terminal (drain of the second back-to-back MOSFET). Forms the other side of the isolated solid-state switch across the load. Load voltage VL up to 600 V (AC peak or DC); load current IL up to 0.08 A.
