That 1.5 kW ceiling means the part survives load-dump and inductive kickback transients common in automotive 12 V power rails, not just the sub-100 W spikes a lower-rated part would handle. ## Clamping chain: standoff, breakdown, and the clamping ceiling Reverse standoff voltage is 7.78 V typ — the part sits idle on the line at normal operating conditions. The gap between 7.78 V standoff and 13.4 V clamping ceiling defines the headroom the protected load sees — a microcontroller or CAN transceiver running at 5 V rail sits comfortably inside it. That simplifies the layout: one device protects the power rail and the signal return simultaneously. ## Automotive grade: AEC-Q101 at 150°C junction AEC-Q101 qualification means the part passed the automotive stress suite — humidity, temperature cycling, and surge testing at the component level. Surface-mount DO-214AB (SMC) footprint is compatible with standard reflow assembly — no through-hole hand-soldering required. The Tape & Reel packaging suits high-volume pick-and-place lines. Available to order through independent distribution against an RFQ. Telecom and automotive programs with long production runs should confirm the automotive-grade sourcing path and whether full PPAP documentation is required for the specific platform before committing to quantity.","metaTitle":"Vishay 1.5SMC9.1CAHM3/I TVS Diode, 1500W 9.1V AEC-Q101 SMC","metaDescription":"Vishay 1.5SMC9.1CAHM3/I: automotive AEC-Q101 bidirectional TVS Zener, 1500W peak pulse, 112A.
