HCPL-0501-500E from Broadcom AVAGO, 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 | No internal connection; the datasheet shows this pin as NC on the SO-8 package. |
| 2 | ANODE | input | LED anode input; the reverse LED input voltage rating for SO-8 is 5 V (Pin 3-2). |
| 3 | CATHODE | input | LED cathode input; average forward input current is limited to 25 mA and peak forward input current to 50 mA (1 ms pulse, 50% duty cycle) per the absolute maximum ratings. |
| 4 | NC | unconnected | No internal connection; the datasheet shows this pin as NC on the SO-8 package. |
| 5 | GND | power_in | Ground reference for the detector and output stage (VCC, VO and VB are referenced to pin 5); a 0.1 µF bypass capacitor must be connected between pins 5 and 8. |
| 6 | VO | output | Open-collector logic output; average output current is limited to 8 mA and peak output current to 16 mA, with output voltage (Pin 6-5) rated up to 15 V for SO-8. |
| 7 | VB | power_in | Base connection of the integrated photodetector (separate photodiode bias connection); base current is limited to 5 mA maximum (Pin 7). |
| 8 | VCC | power_in | Supply voltage pin referenced to pin 5; the SO-8 absolute maximum supply voltage is 15 V, and a 0.1 µF bypass capacitor is required between pins 5 and 8. |
