US1MFA Description

Short technical summary and product information.

The US1MFA is a super fast surface mount rectifier from onsemi, designed for high-efficiency power conversion. It offers a maximum repetitive peak reverse voltage of 1000V and an average forward current of 1A, making it suitable for a variety of rectification applications.

 

Key electrical characteristics include a low forward voltage of 1.7V at 1A and a fast reverse recovery time of 75ns, which minimizes switching losses. The device can handle a peak forward surge current of 30A (8.3ms single half sine-wave), providing robustness during transient conditions.

 

The US1MFA is packaged in a SOD-123FL surface mount package, which is Pb-free, halogen free, and RoHS compliant. It has an MSL rating of 1 per J-STD-020 and UL flammability classification 94V-0. The operating junction temperature range is -55°C to +150°C.
