BT138S-600D

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

BT138S-600D from JSMSEMI, 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 T1 passive Main terminal T1 of the triac; the datasheet rates the part for 600 V VDRM/VRRM and 12 A IT(RMS).
2 T2 passive Main terminal T2 of the triac; the datasheet rates the part for 600 V VDRM/VRRM and 12 A IT(RMS).
3 G input Gate terminal; the BT138S-600D has IGT max 5 mA in quadrants I-II-III and 10 mA in quadrant IV (VD=12 V, RL=33 Ω), with VGT max 1 V.
