P0102BL5AA4

STMicroelectronics · Thyristors (SCR)/Modules · SOT-23

P0102BL5AA4 from STMicroelectronics, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode terminal of the sensitive SCR; current-carrying terminal, on-state rms current up to 0.25 A in the SOT23-3L package.
2 G input Gate terminal used to trigger the SCR into conduction; triggering gate current (IGT) up to 200 µA max (VD = 12 V, RL = 140 Ω).
3 A passive Anode terminal of the sensitive SCR; blocks repetitive peak off-state voltage (VDRM/VRRM) according to the device voltage grade.
