# BC33716BU

**onsemi** · Bipolar (BJT) · TO-92

BC33716BU from onsemi, in a TO-92. 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 | Collector | passive | Collector terminal of the NPN transistor; the datasheet rates collector current at 800 mA DC maximum and collector-emitter voltage at 50 V (BC337) or 30 V (BC338) VCES. |
| 2 | Base | passive | Base terminal of the NPN transistor; the datasheet gives no base-specific limit, only the emitter-base breakdown of 5 V (IE = 0.1 mA). |
| 3 | Emitter | passive | Emitter terminal of the NPN transistor; the emitter-base voltage rating is 5 V. |
