2SD1620-TD-E

onsemi · Bipolar (BJT) · SOT-89-3

2SD1620-TD-E from onsemi, in a SOT-89-3. 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 passive Base terminal of the NPN transistor; the datasheet gives emitter-to-base breakdown V(BR)EBO of 6 V (IE=10μA, IC=0A) and emitter-to-base voltage VEBO of 6 V as absolute maximum ratings.
2 Collector passive Collector terminal; absolute maximum ratings are VCBO 30 V, VCEO 10 V, VCEX 20 V, continuous collector current IC 3 A and pulse current ICP 5 A.
3 Emitter passive Emitter terminal; the emitter-to-base voltage limit is VEBO 6 V, and the datasheet gives no separate emitter-specific rating.
