BYW51-200G

BYW51-200G Description

The BYW51-200G from onsemi is a high-performance fast recovery diode array designed for demanding power electronics applications. Part of the SWITCHMODE™ series, it features a 200V reverse voltage (Vr) and 8A average rectified current (Io) per diode, making it suitable for high-efficiency switching circuits. Its ultra-fast recovery time of 35ns and low forward voltage drop (970mV @ 8A) minimize power losses, enhancing thermal performance and system reliability. The diode array is configured as 1 pair common cathode, simplifying circuit design in compact layouts. Packaged in a TO-220 tube, it is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.

BYW51-200G Features

• Fast Recovery: ≤500ns recovery time (>200mA), ideal for high-frequency switching.
• Low Leakage: 10µA @ 200V ensures minimal standby power dissipation.
• High Current Handling: 8A per diode with robust thermal performance.
• Low Vf: 970mV @ 8A reduces conduction losses.
• TO-220 Package: Through-hole mounting for easy assembly and heat dissipation.
• Reliable Technology: Standard diode technology with 35ns trr for efficient switching.
• Compliance: ROHS3, REACH, and EAR99 certified for global use.
