Breakdown voltage minimum is 64.6 V — the TVS begins to clamp once the surge pushes the rail above this threshold. Clamping voltage maximum is 92 V at the rated 17 A peak pulse current — this is the voltage that appears at the load during a fault event and determines whether downstream circuits survive. ## Automotive grade for the full temperature envelope Junction temperature rating is -55 °C to 150 °C — this covers the engine-bay ambient band where many automotive protection circuits sit, and a 150 °C Tj ceiling gives margin against thermal runaway during repeated surge events. AEC-Q101 qualification means the device has passed the automotive stress suite — humidity, temperature cycling, and surge lifecycle — making it deployable in chassis and powertrain domains without a derating concern. ## Active and sourced to order Tape-and-reel packaging suits high-volume SMT line placement; confirm the MSL rating and dry-storage handling with the supplier before reflow if the reels have been stored long-term.","metaTitle":"1.5SMC68CAHM6G TVS Diode, 58.1V standoff, 1500W peak","metaDescription":"1.5SMC68CAHM6G: 1500W peak pulse TVS in DO-214AB, AEC-Q101 automotive, -55°C to 150°C.

Breakdown (64.6 V min) is where it first begins to conduct during a surge. Clamping (92 V max at 17 A) is the voltage the downstream load actually sees while the TVS is actively shunting fault current — that 92 V figure is the one that determines whether your downstream circuit survives."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC68CAHM6G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5SMC68CAHM6G when reusing this data.
