JST137K-800E

Jiangsu JieJie Microelectronics · Thyristors (SCR)/Modules · TO-252-2

JST137K-800E from Jiangsu JieJie Microelectronics, in a TO-252-2. 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 1 (T1) carries the on-state current; the 8 A RMS on-state current rating for TO-252 is specified at TC=110℃.
2 T2 passive Main terminal 2 (T2) carries the on-state current and is rated for 800 V repetitive peak off-state voltage (VDRM/VRRM) for this -800 part, with 65 A non-repetitive surge peak on-state current (full cycle, 50 Hz).
3 G input Gate triggers the triac with IGT of 10 mA max in quadrants I-III for grade E at Tj=25℃, with peak gate current limited to 2 A and average gate power to 0.5 W.
