Description
The HCS80R380S is an 800V N-channel super junction power MOSFET, engineered for high-efficiency power conversion applications. Housed in the isolated TO-220FS through-hole package, it's designed to efficiently switch or amplify electronic signals in demanding, high-voltage power circuits.
This MOSFET features a very low figure of merit (FOM = RDS(on) × Qg), delivering extremely low switching loss combined with excellent stability and uniformity across production units. With a breakdown voltage of up to 850V (BVDSS @ Tj,max), a maximum RDS(on) of 0.38Ω, a continuous drain current of 13A, and a typical gate charge of just 29nC, it's built for both efficient conduction and fast, low-loss switching. The device is 100% avalanche tested and includes a built-in ESD protection diode for enhanced reliability in real-world operating conditions.
Its super junction structure and isolated TO-220FS package make it a strong fit for high-voltage switching applications requiring good thermal performance without a separate insulating mica pad — commonly used across switch-mode power supplies, UPS systems, and power factor correction circuits.
