MS9435

MSKSEMI · MOSFETs · SOP-8

MS9435 from MSKSEMI, in a SOP-8. 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 Source passive Source terminal of the MOSFET; the datasheet rates the device at VDS = -30 V and continuous ID = -5.3 A at VGS = -10 V.
2 Source passive Source terminal of the MOSFET, connected internally with pins 1 and 3; the datasheet rates the device at VDS = -30 V and continuous ID = -5.3 A at VGS = -10 V.
3 Source passive Source terminal of the MOSFET, connected internally with pins 1 and 2; the datasheet rates the device at VDS = -30 V and continuous ID = -5.3 A at VGS = -10 V.
4 Gate input Gate terminal of the MOSFET; the absolute maximum gate-source voltage is VGS = ±20 V.
5 Drain passive Drain terminal of the MOSFET; the drain-source voltage rating is VDS = -30 V.
6 Drain passive Drain terminal of the MOSFET, connected internally with pins 5, 7 and 8; the drain-source voltage rating is VDS = -30 V.
7 Drain passive Drain terminal of the MOSFET, connected internally with pins 5, 6 and 8; the drain-source voltage rating is VDS = -30 V.
8 Drain passive Drain terminal of the MOSFET, connected internally with pins 5, 6 and 7; the drain-source voltage rating is VDS = -30 V.
