D Series High Voltage Power MOSFETs Vishay / Siliconix D Series High Voltage Power MOSFETs are Vishay's next-generation high voltage N-Channel MOSFETs available in 400V, 500V, and 600V ratings. These new devices combine low specific on-resistance with ultra-low gate charge, currents from 3.0A to 36A and are available in a wide range of packages. Features include Vishay's new high-voltage stripe technology, on-resistance down to 0.13Ω, gate charge down to 6nC, best-in-class gate charge times on-resistant figures of merit (FOM) down to 7.65ΩnC, and avalanche rated for reliable operation. Typical applications include high-power, high-performance switch mode applications, including server and telecom power systems, welding, plasma cutting, battery chargers, ballast light, high-intensity discharge (HID) lighting, semiconductor capital equipment, and induction heating.
