IRFU310BTU Description

Short technical summary and product information.

The IRFU310BTU is an N-Channel power MOSFET manufactured by On Semiconductor. It is designed for switching and amplification applications requiring high voltage capability. The device features a maximum drain-to-source voltage of 400V and a continuous drain current of 1.7A at case temperature. The on-resistance is 3.4 Ohm at 850mA and 10V gate drive.

 

This MOSFET is built with MOSFET (Metal Oxide) technology and offers a gate threshold voltage of 4V at 250µA. The input capacitance is 330pF at 25V, and the total gate charge is 10nC at 10V, making it suitable for moderate-speed switching applications. Maximum power dissipation is 2.5W at ambient temperature and 26W at case temperature.

 

The device is housed in a through-hole TO-251-3 (IPAK) package, which allows for easy mounting on printed circuit boards. The operating junction temperature range is -55°C to 150°C, ensuring reliable performance in harsh environments.
