# TIP132

**STMicroelectronics** · Darlington Transistors · TO-220

TIP132 from STMicroelectronics, in a TO-220. 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 | B | input | Base of the NPN Darlington (internal R1 typ. 5 kΩ, R2 typ. 150 Ω); IB max 0.3 A and VEBO max 5 V. |
| 2 | C | passive | Collector (connected to the mounting tab); VCEO 60 V for TIP132, IC 8 A continuous, 12 A peak. |
| 3 | E | passive | Emitter of the Darlington, with an internal collector-emitter diode; VEBO max 5 V. |

## CAD (KiCad official)

- Symbol: `TIP132`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `tip132-etched.step` / `tip132-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tip132.step` / `tip132.glb` are the bare package body.
