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

BT136 from JUXING, 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 terminal opposite T2 in the symbol, where the gate G is referenced); the part is rated 4 A RMS on-state current and 600/800 V repetitive peak off-state voltage.
2 T2 passive Main terminal T2 of the triac, also connected to the TO-252 tab; the part is rated 4 A RMS on-state current and 600/800 V repetitive peak off-state voltage.
3 G input Gate trigger terminal; peak gate current is rated 2 A, peak gate voltage 5.0 V and peak gate power 5.0 W.
