FDG6303N

onsemi · MOSFETs · SC-70-6

FDG6303N from onsemi, in a SC-70-6. 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 S1 passive Source of FET 1; pins 1 and 4 are interchangeable because the pinout is symmetrical.
2 G1 input Gate of FET 1 with a gate-source Zener for ESD protection (VGSS -0.5 to +8 V, VGS(th) < 1.5 V).
3 D2 passive Drain of FET 2 (VDSS 25 V, 0.5 A continuous, 1.5 A pulsed).
4 S2 passive Source of FET 2; pins 1 and 4 are interchangeable because the pinout is symmetrical.
5 G2 input Gate of FET 2 with a gate-source Zener for ESD protection (VGSS -0.5 to +8 V, VGS(th) < 1.5 V).
6 D1 passive Drain of FET 1 (VDSS 25 V, 0.5 A continuous, 1.5 A pulsed).
