The standoff voltage of 6.4 V sets the working voltage the protected rail sees in normal operation; the breakdown minimum of 7.13 V is the threshold where the TransZorb begins to clamp, and the clamping voltage ceiling of 11.3 V at 133 A peak pulse is what the downstream circuitry actually survives. For an automotive ECU input or supply rail protection circuit, the 11.3 V clamp — not the 6.4 V standoff — is the stress number the downstream semiconductor sees. ## TransZorb versus a standard Zener — series designation matters The TransZorb series designation marks this as a Silicon Transient Voltage Suppressor — it behaves like a Zener in normal operation but is rated for a defined peak pulse power and current that a standard Zener diode is not. A standard Zener datasheet gives you Vz and Pz at continuous DC; the TransZorb datasheet gives you the peak pulse power curve (10/1000 µs and 8/20 µs), the clamping voltage at a specific peak current, and the AEC-Q101 automotive qualification flow. If you are specifying by Zener voltage alone, you may be undersizing the transient capability. For an ECU module that must survive under-hood temperature and voltage transients, an unrated Zener in the same voltage class is not a functionally equivalent substitute without independent qualification data.","metaTitle":"Vishay 1N6268AHE3_A/C, 1500W Peak Pulse Zener TVS","metaDescription":"Vishay 1N6268AHE3_A/C, Automotive AEC-Q101 TransZorb, 1500W peak pulse, 11.3V clamping.

Suffix variants within the 1N6268 series share the same breakdown and clamping ratings but differ in polarity orientation (A/C vs A). Confirm the suffix match against your schematic polarity before cross-referencing — the lead tape orientation also varies by suffix. Cross-reference alternatives outside the 1N6268 base number require parametric validation against your clamping voltage and peak pulse current requirements."},{"question":"What is the 1N6268AHE3_A/C's listed type and series on the Circuit Protection line?","answer":"The listed type is Zener, belonging to the Automotive AEC-Q101 TransZorb series — a transient voltage suppressor family rated for peak pulse events in automotive supply protection circuits rather than standard DC reference applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1N6268AHE3_A-C","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1N6268AHE3_A-C when reusing this data.
