About the onsemi 1N44 Series
The onsemi 1N44 Series series groups 8 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. The listed variants share a common current - reverse leakage @ vr of 5 µA @ 75 V, reverse recovery time of 4 ns and speed of Small Signal =< 200mA (Io), Any Speed. 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. The range mixes active and legacy part numbers, so you can source both current onsemi 1N44 Series variants and discontinued ones from a single page.
