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. |
