onsemi · Bipolar Transistors - BJT · TO-126
BD13516STU from onsemi, in a TO-126. 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 terminal of the NPN transistor; the datasheet gives no further electrical limits for this pin. |
| 2 | Collector | passive | Collector terminal of the NPN transistor; the collector-base and collector-emitter voltage limits are given in the absolute maximum ratings table (BD135 45 V, BD137 60 V, BD139 80 V). |
| 3 | Base | input | Base terminal of the NPN transistor; the datasheet gives a base current limit of 0.5 A in the absolute maximum ratings. |
