At 85 V maximum clamping voltage with a 17.9 A peak pulse (10/1000 µs), the device absorbs 1500 W of surge energy before the clamping ceiling is reached. That tight window — roughly 32 V between standoff and clamp — is what sets this apart from a plain Zener: it stays invisible on the line until the event forces it to act. ## Automotive qualification and thermal margin AEC-Q101 qualification places this in the automotive grade pool — it carries the temperature cycling, humidity, and electrical stress screening the automotive lifecycle demands. Junction temperature is rated to 150°C, which covers the under-hood and cabin thermal environment without derating the clamping performance for most 12 V and 24 V load-dump profiles. The DO-214AB (SMC) package is the standard pick-and-place footprint for unidirectional TVS in automotive ECU designs — the cathodedot marks the polarity side, and the wide metal tab under the body handles the thermal path to the PCB pad.","metaTitle":"Bourns 1.5SMC62A-Q TVS Diode, 53V Standoff, 85V Clamp","metaDescription":"Bourns 1.5SMC62A-Q unidirectional Zener TVS, 1500W peak pulse, AEC-Q101 qualified for automotive.
