FH4604D

XIN FEI HONG · MOSFETs · TO-252-4L

FH4604D from XIN FEI HONG, in a TO-252-4L. 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 the N-channel MOSFET (VDS 40V, ID 25A at TC=25°C, VGS ±20V).
2 G1 input Gate of the N-channel MOSFET (VGS ±20V max, VGS(th) 1.0 to 2.0V).
3 S2 passive Source of the P-channel MOSFET (VDS -40V, ID -21A at TC=25°C, VGS ±20V).
4 G2 input Gate of the P-channel MOSFET (VGS ±20V max, VGS(th) -1.0 to -2.0V).
5 D1/D2 passive Exposed tab, common drain of the N-channel (D1) and P-channel (D2) MOSFETs, joined as in the H-bridge half-bridge schematic and used for heat dissipation.
