KO6604

KEXIN · MOSFETs · SOT-23-6

KO6604 from KEXIN, in a SOT-23-6. 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 Gate1 input Gate terminal of channel 1 of the complementary MOSFET pair; the datasheet gives a gate-source voltage rating of ±8 V for the device.
2 Source2 passive Source terminal of channel 2 of the complementary MOSFET pair, with the source-to-drain rating of ±20 V set by the N- and P-channel devices (N: VDS 20 V, P: VDS -20 V).
3 Gate2 input Gate terminal of channel 2 of the complementary MOSFET pair; the datasheet gives a gate-source voltage rating of ±8 V for the device.
4 Drain2 passive Drain terminal of channel 2 of the complementary MOSFET pair; continuous drain current is rated 3.4 A (N-channel) and -2.5 A (P-channel) at Ta = 25°C.
5 Source1 passive Source terminal of channel 1 of the complementary MOSFET pair, with the source-to-drain rating of ±20 V set by the N- and P-channel devices (N: VDS 20 V, P: VDS -20 V).
6 Drain1 passive Drain terminal of channel 1 of the complementary MOSFET pair; continuous drain current is rated 3.4 A (N-channel) and -2.5 A (P-channel) at Ta = 25°C.
