The 8.5V reverse standoff voltage means the diode stays transparent below that DC level, then avalanches at a minimum breakdown of 9.44V. Clamping is specified at 15.9V maximum at 31.4A peak pulse current — the voltage a downstream IC sees during a surge. Microchip lists the SMAJ8.5E3/TR13 as Active. The DO-214AC (SMA) package is a standard JEDEC outline — the same footprint used by Littelfuse, Vishay, and Bourns for their SMAJ-series parts.","metaTitle":"SMAJ8.5E3/TR13 Zener TVS Diode 500W 8.5V DO-214AC","metaDescription":"Microchip SMAJ8.5E3/TR13 Zener TVS, 500W peak pulse, 8.5V reverse standoff, DO-214AC (SMA).

The SMAJ8.5A (bidirectional) and SMAJ8.5CA (bidirectional, different suffix) share the same footprint but differ in polarity. For a unidirectional replacement with identical ratings, any SMAJ8.5E3 variant from Microchip or a cross from Littelfuse/Vishay with the same 8.5V standoff and 500W rating will fit the board without layout changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ8.5E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ8.5E3-TR13 when reusing this data.
