Additional Details
The SSH7N90A features a drain-source voltage (Vds) of 900V, making it suitable for high-voltage applications. The low Rds(on) value minimizes conduction losses, while the fast switching speed reduces switching losses. The avalanche rating ensures that the MOSFET can withstand transient voltage spikes. The gate-source voltage (Vgs) is typically rated at +/-30V. The device is typically available in a through-hole package. The datasheet provides detailed information on the operating characteristics, including the Rds(on) value at various gate-source voltages and temperatures, the switching times, and the avalanche energy rating. It is commonly used in applications where high voltage and high efficiency are critical requirements. The device is designed to be robust and reliable in demanding power switching applications. The continuous drain current (Id) rating depends on the operating conditions and package.
