BD13516STU

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.
