FQP4N90C Description

Short technical summary and product information.

The FQP4N90C is an N-Channel enhancement mode MOSFET manufactured using MOSFET (Metal Oxide) technology. It is designed for high-voltage switching applications requiring efficient power management.

 

Key electrical specifications include a drain-to-source voltage (Vdss) of 900V, a continuous drain current of 4A at case temperature (Tc), and a maximum on-resistance (Rds on) of 4.2 Ohms at a gate drive of 10V and 2A drain current. The device features a maximum gate charge of 22 nC at 10V and an input capacitance of 960 pF at 25V drain-source voltage. The gate threshold voltage is a maximum of 5V at 250 µA drain current, and the maximum gate-source voltage is ±30V.

 

The device is housed in a standard TO-220-3 package with through-hole mounting, suitable for easy integration into power circuits. It can dissipate up to 140W of power and operates over a junction temperature range of -55°C to 150°C.
