The 1500W peak pulse power rating tells you the device survives a single-event transient of that energy without degradation — critical for automotive load-dump and telecom surge events. ## AEC-Q101 qualification and thermal envelope AEC-Q101 stress testing covers the specific failure modes discrete semiconductors face — temperature cycling, humidity, surge repetition — so this part belongs in an ECU, BCM, or ADAS module without needing a waiver. The DO-214AB (SMC) package gives a larger thermal pad than the smaller SMA — the cathode tab area under the body sets the RthJA and is the primary thermal path to the PCB copper. Verify the recommended footprint and solder mask opening in the datasheet; a dry joint under the SMC tab is the most common assembly defect that gets blamed on the TVS failing early. ## Active production — what that buys you in a BOM decision Listed as Active, so the part is in current Vishay production and supported for new designs — no last-time-buy math, no broker markup risk for a clean automotive program. The I-grade suffix on 1.5SMC68AHM3/I indicates enhanced screening; confirm the exact data sheet control record if your quality department has an incoming inspection requirement for automotive SPICE or IATF 16949 compliance.","metaTitle":"Vishay 1.5SMC68AHM3/I TVS Diode, 92V Clamp, 1.5kW Peak","metaDescription":"Vishay 1.5SMC68AHM3/I unidirectional TVS Zener, AEC-Q101 qualified, 58.1V standoff / 92V clamping, 1.5kW peak pulse, DO-214AB SMC.
