# TIL117M

**onsemi** · Transistor, Photovoltaic Output Optoisolators · DIP-6

TIL117M from onsemi, in a DIP-6. 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 | ANODE | passive | Anode of the gallium arsenide infrared emitting diode (LED input); the TIL117M LED reverse input voltage is 6 V maximum and DC forward input current is 60 mA maximum. |
| 2 | CATHODE | passive | Cathode of the gallium arsenide infrared emitting diode (LED input); DC/average forward input current is limited to 60 mA maximum. |
| 3 | NC | unconnected | No connection, as printed on the datasheet pinout and schematic; leave unconnected. |
| 4 | EMITTER | passive | Emitter of the silicon phototransistor output; collector-to-emitter voltage is 30 V maximum (VCEO) and emitter-to-collector voltage is 7 V maximum (VECO). |
| 5 | COLLECTOR | passive | Collector of the silicon phototransistor output; collector-to-emitter voltage is 30 V maximum (VCEO) and collector-to-base voltage is 70 V maximum (VCBO). |
| 6 | BASE | passive | Base of the phototransistor output, which can be tied to an external base-emitter resistor RBE to change CTR and switching time as shown in the characterization curves. |

## CAD (KiCad official)

- Symbol: `TIL117M`
- Footprint: `Package_DIP:DIP-6_W7.62mm`
- 3D model: DIP-6 (KiCad packages3D, STEP)
- 3D model files: `til117m-etched.step` / `til117m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `til117m.step` / `til117m.glb` are the bare package body.
