67 variants · onsemi
The onsemi onsemi MMSZ Series series groups 67 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. The listed variants share a common case of SOD-123, mounting type of Surface Mount and power - max of 500 mW. 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 onsemi MMSZ Series variants and discontinued ones from a single page.
