The 58.9 V minimum breakdown is the floor — the device guarantees it triggers no higher than that on a worst-case fast-rising edge. The datasheet's Vc versus Ipp curve is what determines survivable event profiles for your specific load. ## AEC-Q101 automotive qualification and thermal margin The AEC-Q101 designation is the automotive-grade stress qualification — it certifies the part passed temperature cycling, humidity bias, and surge testing to a standard that covers chassis and powertrain environments, not just cabin-level thermal conditions. Thermal design of the board pad and trace copper under the cathode tab determines how many pulses the part survives at rated peak current. Single bidirectional channel — this is the unidirectional-only protection topology; if AC-line polarity reversal is a real fault mode, a unidirectional TVS does not cover it. For a DC rail like automotive battery, the bidirectional variant simply mirrors the clamping characteristic in both polarities, which is redundant unless the protected node sees negative transients from inductive kick during a fault. ## Sourcing posture — active production Active lifecycle — Vishay General Semiconductor — Diodes Division continues this part under the 1.5SMC series with no listed successor. For a new automotive design, qualify the alternate from the same 1.5SMC family now — do not wait for a last-time-buy notice.","metaTitle":"Vishay 1.5SMC62CAHE3/9AT TVS Diode, 1500W, 53V standoff","metaDescription":"Vishay 1.5SMC62CAHE3/9AT — AEC-Q101 automotive bidirectional TVS Zener, 1500W peak pulse, 53V standoff, 85V clamping.

When a load-dump pulse pushes the rail above 58.9 V minimum breakdown, the device clamps at 85 V maximum, protecting downstream components rated for that voltage ceiling. For a 24 V truck system, the same standoff leaves less margin and requires checking the load-dump profile against the 150°C junction limit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5SMC62CAHE3-9AT","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/1.5SMC62CAHE3-9AT when reusing this data.
