Product Overview
Vishay BY203-16STR is a fast recovery rectifier designed for high-voltage applications requiring controlled switching characteristics. Rated at 1600 volts with a forward current of 0.25 amp, this single-configuration through-hole diode is suited for power conversion and high-voltage rectification tasks.
With a maximum surge current of 20 amps (IFSM) and a specified recovery time of 300 nanoseconds, the BY203-16STR is appropriate for circuits where switching speed and surge handling are both important. Its through-hole mounting style supports traditional PCB layouts and repair of legacy equipment.
