2SK4124 Description

Short technical summary and product information.

The 2SK4124 is an N-Channel enhancement-mode MOSFET manufactured by On Semiconductor using MOSFET (Metal Oxide) technology. It is designed for high-voltage switching applications requiring a drain-to-source voltage (Vdss) of 500V and a continuous drain current of 20A. The device features a maximum drain-source on-resistance of 430mOhm at 8A and 10V gate drive, ensuring efficient power handling.

 

This MOSFET offers a maximum gate charge of 46.6nC at 10V and an input capacitance of 1200pF at 30V, contributing to moderate switching performance. The gate-source voltage is rated up to ±30V. Power dissipation is rated at 2.5W at ambient temperature and up to 170W at case temperature, with a maximum junction temperature of 150°C.

 

The 2SK4124 is housed in a through-hole TO-3P-3 / SC-65-3 package, with the supplier device package designated as TO-3PB. This package is suitable for designs requiring robust mechanical mounting and effective heat sinking.
