The 60EPU04PBF is a Ultrafast Soft Recovery Diode from International Rectifier (now Infineon Technologies). This diode is designed for high-frequency rectification applications where fast switching and low losses are crucial. Its soft recovery characteristics minimize voltage overshoot and ringing, reducing EMI (Electromagnetic Interference) and improving overall system performance. The PBF suffix indicates that the component is lead-free and compliant with RoHS standards.

Additional Details

The 60EPU04PBF's ultrafast recovery time and soft recovery characteristics are achieved through its carefully designed epitaxial structure. This structure allows for quick removal of stored charge during reverse recovery, minimizing switching losses and reducing voltage transients. The low forward voltage drop further contributes to improved efficiency and reduces power dissipation. This diode is typically packaged in a TO-247AC, which provides good thermal conductivity. The repetitive peak reverse voltage is 400V and the continuous forward current is 60A, making it suitable for high-power applications. The forward surge current is 450A, for a short duration. The TO-247 package is easy to mount to a heatsink for effective thermal management.
