The IRF840A is a 500V, 8A N-Channel Power MOSFET manufactured by Vishay Siliconix. It is housed in a through-hole TO-220-3 package (TO-220AB). Key electrical specifications include a maximum drain-source voltage of 500V, continuous drain current of 8A at 25°C, and a maximum drain-source on-resistance of 850 mOhm at Vgs=10V. The device features a low gate charge of 38 nC, making it suitable for efficient switching in power conversion circuits.
This MOSFET is characterized for low gate charge, improved gate, avalanche, and dynamic dV/dt ruggedness. It is fully specified for capacitance and avalanche energy, with a single pulse avalanche energy rating of 510 mJ. The operating junction temperature range is -55°C to 150°C, and maximum power dissipation is 125W at 25°C case temperature.
Typical applications include switch mode power supplies (SMPS), uninterruptible power supplies, and high-speed power switching. It is suitable for topologies such as two-transistor forward, half bridge, and full bridge converters. The through-hole TO-220-3 package allows for easy mounting on heatsinks for thermal management.
The maximum drain-source voltage is 500 V.
