FDPF51N25YDTU Description

Short technical summary and product information.

The FDPF51N25YDTU is an N-Channel MOSFET from On Semiconductor, part of the UniFET family. It is designed for high-voltage switching applications with a drain-source voltage rating of 250V and continuous drain current of 51A at 25°C case temperature. The device features a low maximum on-resistance of 60mOhm at 10V gate drive, with a typical value of 48mOhm. Gate charge is typically 55nC (max 70nC), enabling fast switching performance. Input capacitance is 3410pF typical, and reverse transfer capacitance is 63pF typical. The MOSFET is avalanche rated with a single pulse avalanche energy of 1111mJ and repetitive avalanche energy of 32mJ. It offers an insulation voltage of 2500V RMS from leads to heat sink. The device is housed in a TO-220-3 Full Pack package with formed leads (TO-220F-3), suitable for through-hole mounting. Operating temperature range is -55°C to 150°C. Typical applications include PDP TV power supplies, lighting, uninterruptible power supplies, and AC-DC power converters.
