IRF820PBF VISHAY Power MOSFET

The IRF820PBF from Vishay is a classic N-channel power MOSFET rated for 500V drain-to-source voltage and 2.5A continuous drain current, delivering 50W power dissipation in a TO-220AB package. For new designs, select this through-hole device when you need a robust, easily mountable switch for offline power supplies, flyback converters, or high-voltage DC-DC stages. Its 3-ohm max Rds(on) at 10V gate drive and 24nC gate charge make it well-suited for low-frequency switching applications where ruggedness matters more than ultra-low resistance. Typical applications include LED lighting drivers, auxiliary power supplies for industrial equipment, motor start-up circuits, and simple electronic ballasts. The wide -55°C to +150°C junction temperature range ensures reliability in harsh thermal environments. Use this MOSFET when prioritizing proven reliability, easy prototyping, and wide safety margins over the lowest on-resistance. In stock at HL Electronics – request a quote for fast delivery.
