FUXINSEMI · Thyristors (SCR)/Modules · TO-252

BT137D-800E from FUXINSEMI, in a TO-252. 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 A1 passive Main terminal 1 (MT1 / anode 1). Reference terminal for the gate trigger voltage V_GT. Carries the AC load current together with A2 (I_T(RMS) = 8 A).
2 A2 passive Main terminal 2 (MT2 / anode 2), electrically connected to the exposed metal tab of the TO-252AB package. Rated for V_DRM/V_RRM = 800 V and I_T(RMS) = 8 A. Carries the AC load current together with A1.
3 G input Gate trigger input. Referenced to A1. V_GT(max) = 1.5 V; I_GT(max) = 10 mA in quadrants I/II/III and 25 mA in quadrant IV. Peak gate current I_GM = 2 A.
