TLPN137 from TOSHIBA, in a DIP-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 | N.C. | unconnected | Not connected (N.C.) per the pin configuration; the datasheet gives no function or limit for this pin. |
| 2 | Anode | input | LED anode input; the datasheet specifies input forward current IF of 20 mA absolute maximum and recommended IF(ON) of 6.3 to 15 mA. |
| 3 | Cathode | input | LED cathode; the input reverse voltage VR is rated at 5 V maximum and input forward current is limited to 20 mA. |
| 4 | N.C. | unconnected | Not connected (N.C.) per the pin configuration; the datasheet gives no function or limit for this pin. |
| 5 | GND | power_in | Ground reference for the detector; a 0.1 µF ceramic capacitor should be connected between pin 8 and pin 5, placed within 1 cm of each pin, to stabilize the high-gain amplifier. |
| 6 | VO (Output) | output | Open-collector logic output (inverter type) with absolute maximum output voltage VO of 6 V and output current IO of 50 mA; sinks 13 mA with VO below 0.6 V in the low state. |
| 7 | N.C. | unconnected | Not connected (N.C.) per the pin configuration; the datasheet gives no function or limit for this pin. |
| 8 | VCC | power_in | Supply voltage pin rated 4.5 to 5.5 V recommended (6 V absolute maximum), to be bypassed to pin 5 with a 0.1 µF ceramic capacitor. |
