ACNT-H313-500E from AVAGO(Broadcom), in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	Not connected; the CMR test notes say pins 1 and 4 are tied to LED common.
2	ANODE	input	LED anode; recommended LED on-current IF(ON) is 7 to 12 mA, with a maximum average input current of 25 mA.
3	CATHODE	input	LED cathode; the recommended off-state input voltage VF(OFF) is -3.6 to 0.5 V, and the maximum reverse input voltage is 5 V.
4	NC	unconnected	Not connected; the CMR test notes say pins 1 and 4 are tied to LED common.
5	VEE	power_in	Negative output supply, normally ground; VCC - VEE must be 15 to 30 V, with an absolute maximum of 35 V.
6	VOUT	output	Gate drive output with 2.0 A minimum peak output current. Output voltage ranges from -0.5 V to VCC.
7	VCC	power_in	Positive output supply, 15 to 30 V above VEE, with UVLO. A 0.1 uF bypass capacitor must be connected between VCC and VEE.
8	NC	unconnected	Not connected.
