# JMSH1509AC-U

**Jiangsu JieJie Microelectronics** · Bipolar (BJT) · TO-220-3L

JMSH1509AC-U from Jiangsu JieJie Microelectronics, in a TO-220-3L. 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 | G | input | Gate control input with an absolute maximum gate-to-source voltage of ±20 V and a gate threshold voltage of 2.5 V min to 4.5 V max. |
| 2 | D | passive | Drain terminal rated for 150 V drain-to-source voltage and 90 A continuous drain current at TC = 25°C, with a 335 A pulsed limit. |
| 3 | S | passive | Source terminal carrying the full drain current, with a body-diode continuous current of 179 A at TC = 25°C. |
