# TIL113M

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

TIL113M 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 emitter (LED); the LED continuous forward current is rated at 80 mA maximum. |
| 2 | CATHODE | passive | Cathode of the gallium arsenide infrared emitter (LED); the LED reverse voltage is rated at 3 V maximum. |
| 3 | N/C | unconnected | No connection; this pin is not connected internally. |
| 4 | EMITTER | passive | Emitter of the silicon planar photodarlington detector; the emitter-collector breakdown voltage (BVECO) is rated 5 V in the absolute maximum ratings. |
| 5 | COLLECTOR | passive | Collector of the silicon planar photodarlington detector; the collector-emitter breakdown voltage (BVCEO) is rated 30 V and the continuous collector current 150 mA in the absolute maximum ratings. |
| 6 | BASE | passive | Base of the photodarlington detector, which can be left open or tied to an external base-emitter resistor RBE to adjust switching speed and CTR as shown in the RBE characteristic curves. |

## CAD (KiCad official)

- Symbol: `TIL113M`
- Footprint: `Package_DIP:DIP-6_W7.62mm`
- 3D model: DIP-6 (KiCad packages3D, STEP)
- 3D model files: `til113m-etched.step` / `til113m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `til113m.step` / `til113m.glb` are the bare package body.
