MUR490E
The MUR490E is a 900 V, 4 A ultrafast rectifier diode from ON Semiconductor, designed for high-speed switching in power electronics. It comes in a DO‑201AD package and is avalanche-rated, providing reliable performance in inverters, SMPS, motor drives, solar installations, welding equipment, and telecom power circuits.
The diode features a low forward-voltage drop of 1.85 V at 4 A, reducing conduction losses during operation. Its reverse recovery time of 75 ns supports efficient high-frequency switching. The device handles a controlled avalanche energy of 20 mJ and operates over a junction temperature range of –65 °C to +175 °C, making it suitable for demanding industrial environments.
The MUR490E supports automated assembly due to its through-hole package and meets RoHS and Pb-free standards. Its specifications allow use in solar inverters, SMPS, welding power supplies, and motor-drive systems where reliable rectification is required.
