The 43V clamp is the worst-case voltage across the diode at the rated 11.6A peak pulse current — that is the voltage your protected ICs must survive for the duration of the surge. For BOM quantities, we source this part to order — confirm current pricing and lead time by submitting an RFQ.","metaTitle":"SMAJ24E3/TR13 – Microchip 24V Unidirectional TVS Diode, 500W","metaDescription":"Microchip SMAJ24E3/TR13 Zener TVS diode: 24V reverse standoff, 26.7V breakdown, 43V clamp at 11.6A, 500W peak pulse, DO-214AC.

Confirm with the datasheet or your Microchip representative for formal certification."},{"question":"What is the difference between the SMAJ24E3 and the SMAJ24A?","answer":"The SMAJ24A is a bidirectional TVS, while the SMAJ24E3 is unidirectional. For a single 24V rail referenced to ground, the unidirectional part is the correct choice; for AC or dual-polarity lines, you would use the bidirectional SMAJ24A. Both share the same DO-214AC package and 500W peak pulse rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ24E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ24E3-TR13 when reusing this data.
