2SA1627AL-K-TN3-R

UTC Unisonic Tech · Bipolar (BJT) · TO-252

2SA1627AL-K-TN3-R from UTC Unisonic Tech, 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 B input Base terminal of the PNP transistor; the datasheet gives base drive only as test conditions (IB = -0.06 A at IC = -0.3 A for saturation, and IB1 = -IB2 = -0.1 A in switching tests), with emitter-base voltage rated at VEBO = -7.0 V.
2 C passive Collector terminal; rated for VCBO = -600 V, VCEO = -600 V, DC collector current IC = -1.0 A and pulsed current ICP = -2.0 A (PW ≤ 10 ms, duty cycle ≤ 50%), with TO-252 collector power dissipation of 1.9 W.
3 E passive Emitter terminal; the emitter-base voltage is rated at VEBO = -7.0 V (emitter-base cut-off test at VEB = -7.0 V, IC = 0).
