# HCNR200-000E

**Broadcom AVAGO** · Transistor, Photovoltaic Output Optoisolators · DIP-8

HCNR200-000E from Broadcom AVAGO, in a DIP-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 | LED_CATHODE | passive | Cathode of the input-side AlGaAs LED. Forward current I_F through the LED (anode pin 2 to cathode pin 1) generates the optical stimulus for both photodiodes. |
| 2 | LED_ANODE | passive | Anode of the input-side AlGaAs LED. Drive current I_F flows from this pin (V_F forward voltage) through the LED to pin 1 cathode. |
| 3 | PD1_CATHODE | passive | Cathode of the input-side (servo/monitor) photodiode PD1. Photocurrent I_PD1 is proportional to the LED optical output and is used in a feedback loop to stabilize the LED drive. |
| 4 | PD1_ANODE | passive | Anode of the input-side (servo/monitor) photodiode PD1. Returns the photocurrent I_PD1 to the input-side circuit ground/summing node. |
| 5 | PD2_ANODE | passive | Anode of the output-side photodiode PD2. Isolated from the input side by the safety-approved insulation barrier; sources/returns photocurrent I_PD2 on the output side. |
| 6 | PD2_CATHODE | passive | Cathode of the output-side photodiode PD2. Photocurrent I_PD2 is closely matched to I_PD1 (transfer gain K3 = IPD2/IPD1, ±15% for HCNR200), producing the isolated analog output signal. |
| 7 | NC | unconnected | No internal connection. Leave floating or tie as convenient for layout/creepage. |
| 8 | NC | unconnected | No internal connection. Leave floating or tie as convenient for layout/creepage. |
