It is AEC-Q101 qualified, meaning it meets the automotive-grade reliability stress and temperature cycling requirements for under-hood and chassis-mounted electronics. ## Package and board integration The SMC footprint is standard for 1500W-class TVS diodes and mates with common PCB layouts for this power level. The operating junction temperature range spans -65°C to 150°C, covering the full automotive temperature envelope from cold crank to under-hood heat soak. No power line protection is built in — this is a dedicated transient suppressor for signal or DC power bus clamping. ## Sourcing and lifecycle posture The base product number is 1.5SMC120, and the full suffix HM3/I indicates the automotive-grade qualification and packaging variant.","metaTitle":"1.5SMC120CAHM3/I TVS Diode, 1500W, Bidirectional, DO-214AB","metaDescription":"Vishay 1.5SMC120CAHM3/I bidirectional TVS diode, 1500W peak pulse power, 102V standoff, AEC-Q101 qualified.
