# 2SD1802T

**Shikues** · Bipolar (BJT) · TO-252

2SD1802T from Shikues, in a TO-252. 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 transistor, which controls the collector current; the datasheet gives no separate pin-level limit for this terminal. |
| 2 | Collector | passive | Collector terminal of the NPN transistor, which carries the collector current with IC continuous rated at 3 A in the datasheet's maximum ratings. |
| 3 | Emitter | passive | Emitter terminal of the NPN transistor, the common reference for the base and collector; the datasheet lists an emitter-base voltage rating of 6 V. |
