About the Micro Commercial Co SMAJ59 Series

The Micro Commercial Co SMAJ59 Series series groups 48 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. The listed variants share a common case of DO-214AC, SMA, mounting of Surface Mount and power - max of 1.5 W. Variants differ by current - reverse leakage @ vr, impedance (Max) and operating temperature, so you can match the exact current - reverse leakage @ vr your application requires using the selection guide below. The range mixes active and legacy part numbers, so you can source both current Micro Commercial Co SMAJ59 Series variants and discontinued ones from a single page.
