Breakdown occurs at a minimum of 31.4 V, and the clamping voltage is held to 45.7 V at the rated peak pulse current of 32.8 A. ## AEC-Q101 qualification and temperature range for under-hood and telecom environments The operating temperature range of -65°C to 150°C (TJ) covers both cold-crank and under-hood soak conditions. Telecom base-station power feeds also benefit from this margin, as outdoor cabinets can exceed 85°C internal ambient. Lifecycle status is Active per the manufacturer — no end-of-life notice or last-time-buy window is in effect. ## DO-214AB (SMC) surface-mount package — board integration notes The cathode band is marked for orientation, though the bidirectional nature of this device means polarity is not critical for the protection function. The device is supplied in Tape & Reel packaging, compatible with automated pick-and-place assembly.","metaTitle":"Vishay 1.5SMC33CAHM3_A/I TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC33CAHM3_A/I bidirectional TVS diode, 1500W peak pulse, 28.2V standoff, AEC-Q101 qualified.
