ACNT-H313-500E

AVAGO(Broadcom) · Optocouplers - Logic Output · SO-8

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.
