Additional Details

The BYQ28EF-200 typically features a reverse voltage rating (VRRM) of 200V and a forward current rating (IF) of 8A. Its hyperfast reverse recovery time (trr) is a key specification, usually in the range of 25 ns or less. The operating temperature range generally spans from -65°C to +175°C. It is commonly packaged in a DO-201AD package. The soft recovery characteristic helps to reduce voltage spikes and EMI during switching transitions. The low forward voltage drop contributes to improved efficiency, while the high surge current capability provides added protection against transient events. Its combination of speed, efficiency, and robustness makes it well-suited for modern power electronics applications.
