Vishay's TransZorb® name marks their oxide-passivated construction — it prevents the leakage creep that degrades standard Zeners under repeated clamping events. Rated for general-purpose applications on non-power-line circuits, it clamps a single polarity. Working voltage sits at the reverse standoff of 6.4 V — the TVS conducts negligible leakage here during normal operation. The minimum breakdown of 7.13 V marks the onset of avalanche conduction; at the rated peak pulse current of 133 A the clamping voltage is held to 11.3 V. Those two numbers — 6.4 V standoff, 11.3 V clamp — define what the downstream circuit sees when a surge arrives. ## Temperature and board context The junction operating range is -65 °C to 150 °C — broad enough for both cold-start industrial enclosures and hot environments near heat sources. The lower bound is relevant for outdoor or vehicle-adjacent deployments; the upper bound sets the ceiling for derating under fault conditions. Surface-mount in the DO-214AB SMC body requires the standard SMC land pattern — short, wide traces to the TVS pins keep loop inductance low, which keeps the clamping overshoot above the datasheet Vc figure to a minimum when the transient rise time is fast. ## Active sourcing posture Listed as Active by Vishay General Semiconductor — Diodes Division. Quoted to order through independent distribution; availability and lot traceability confirmed at RFQ. The base product number 1.5SMC7.5 anchors any family cross-reference if a second-source or compatible alternative is needed.","metaTitle":"Vishay 1.5SMC7.5A-M3/57T TVS Diode, 1.5 kW 6.4 V","metaDescription":"Vishay 1.5SMC7.5A-M3/57T unidirectional TVS diode, 1500W peak pulse power, 6.4V standoff, 11.3V clamping, DO-214AB SMC.

It is not a continuous dissipation rating; a TVS is sized for infrequent surge events, not sustained conduction."},{"question":"How do I size the 1.5SMC7.5A-M3/57T into a protection circuit — what drives the selection?","answer":"Two numbers set the fit: the reverse standoff of 6.4 V must sit above the normal operating rail so the TVS stays off-line, and the 133 A peak pulse current must exceed the available fault current at that voltage so the clamping voltage of 11.3 V protects the downstream load without the TVS exceeding its rated energy. The clamping voltage sets what the protected circuit actually sees during the event."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC7.5A-M3-57T","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/1.5SMC7.5A-M3-57T when reusing this data.
