About the onsemi ESD5Z Series

The onsemi ESD5Z Series series groups 17 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. Every variant in the range shares a common applications of General Purpose, case of SC-79, SOD-523 and mounting of Surface Mount. Variants differ by capacitance @ frequency, current - peak pulse (10/1000μs) and operating temperature, so you can match the exact capacitance @ frequency your application requires using the selection guide below. The range mixes active and legacy part numbers, so you can source both current onsemi ESD5Z Series variants and discontinued ones from a single page.
