About the onsemi S1MF Series

The onsemi S1MF Series series groups 2 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. Every variant in the range shares a common mounting of Surface Mount, package of Tape & Reel (TR) Cut Tape (CT) and speed of Standard Recovery >500ns, > 200mA (Io). Variants differ by capacitance @ vr,, case and current - average rectified, so you can match the exact capacitance @ vr, your application requires using the selection guide below. Listed onsemi S1MF Series part numbers are obsolete or end-of-life — we specialise in sourcing discontinued and hard-to-find onsemi S1MF Series components.
