GAQW212GS from SUPSiC, in a SOP-8. 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	LED1_A	input	Channel 1 input LED anode (E1+). Drive with forward current IF = 5-30 mA (typ 7 mA); VF ≈ 1.2 V. Series resistor required per E1 supply voltage (e.g. 300 Ω @ 3.3 V, 600 Ω @ 5 V).
2	LED1_K	input	Channel 1 input LED cathode (E1-). Return path for channel 1 LED forward current.
3	LED2_A	input	Channel 2 input LED anode (E2+). Drive with forward current IF = 5-30 mA (typ 7 mA); VF ≈ 1.2 V. Independent from channel 1 (2 Form A / 2 input configuration).
4	LED2_K	input	Channel 2 input LED cathode (E2-). Return path for channel 2 LED forward current.
5	OUT2_A	passive	Channel 2 MOSFET output drain (IL2 / VL2). AC or DC load switching; polarity non-critical. Load rated 60 V max, 0.5 A continuous (1.5 A peak, 100 ms pulse), Ron ≈ 0.8 Ω typ.
6	OUT2_B	passive	Channel 2 MOSFET output drain (IL2 / VL2). Pairs with pin 5 as the channel-2 load switch; AC/DC capable due to back-to-back MOSFET topology.
7	OUT1_A	passive	Channel 1 MOSFET output drain (IL1 / VL1). AC or DC load switching; polarity non-critical. Load rated 60 V max, 0.5 A continuous, Ron ≈ 0.8 Ω typ.
8	OUT1_B	passive	Channel 1 MOSFET output drain (IL1 / VL1). Pairs with pin 7 as the channel-1 load switch; AC/DC capable due to back-to-back MOSFET topology.
