# 2SD1623

**Shikues** · Bipolar (BJT) · SOT-89

2SD1623 from Shikues, in a SOT-89. 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 | base | input | Base terminal of the NPN silicon epitaxial planar transistor; the emitter-base breakdown voltage V(BR)EBO is 6 V at IE=100µA with IC=0. |
| 2 | collector | passive | Collector terminal; the datasheet rates the collector-base voltage VCBO at 40 V, collector-emitter voltage VCEO at 25 V, and continuous collector current IC at 1.5 A. |
| 3 | emitter | passive | Emitter terminal of the NPN transistor; the datasheet gives the emitter-base voltage VEBO as 6 V maximum. |

## CAD (KiCad official)

- Symbol: `2SD1623`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89 (KiCad packages3D, STEP)
- 3D model files: `2sd1623-etched.step` / `2sd1623-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2sd1623.step` / `2sd1623.glb` are the bare package body.
