# LP395Z

**Texas Instruments** · Bipolar (BJT) · TO-92-3

LP395Z from Texas Instruments, in a TO-92-3. 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 | EMITTER | passive | Emitter of the NPN power transistor, normally tied to ground in the lamp-driver application; collector-to-emitter voltage is limited to 36V maximum. |
| 2 | BASE | input | Base drive input that sources 0.3 µA typical (2.0 µA max) out of the lead, can be driven up to +36V without damage, and turns the device on if left open. |
| 3 | COLLECTOR | passive | Collector output that delivers a specified 100 mA with internal current, power and thermal limiting, rated for 36V maximum collector-to-emitter voltage. |

## CAD (KiCad official)

- Symbol: `LP395Z`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92-3 (KiCad packages3D, STEP)
- 3D model files: `lp395z-etched.step` / `lp395z-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lp395z.step` / `lp395z.glb` are the bare package body.
