APT4M120K Description

Short technical summary and product information.

The APT4M120K is an N-Channel MOSFET from Microchip Technology designed for high-voltage switching applications. It features a drain-source voltage (Vdss) of 1200V and a continuous drain current (Id) of 5A at 25°C. The device offers a maximum on-resistance (Rds(on)) of 4 Ohm at 2A drain current and 10V gate drive, enabling efficient power handling.

Electrical characteristics include a maximum gate charge (Qg) of 43 nC at 10V and an input capacitance (Ciss) of 1385 pF at 25V drain-source voltage. The gate threshold voltage (Vgs(th)) is 5V maximum at 1mA drain current, and the maximum gate-source voltage is ±30V. The device can dissipate up to 225W at 25°C case temperature and operates over a junction temperature range of -55°C to 150°C.

The APT4M120K is supplied in a TO-220-3 through-hole package, suitable for easy mounting on printed circuit boards. It is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited). This MOSFET is appropriate for high-voltage power supplies, motor drives, and inverter circuits.
