The 234 V maximum clamping voltage defines the peak voltage the downstream circuitry must survive during a 6.4 A pulse. The 1500 W peak pulse rating (10/1000 µs) is the standard TVS power metric — it translates to the device's ability to absorb a defined surge without failing. For shorter transients (e.g., 8/20 µs), the peak power capability is significantly higher, but the 10/1000 µs figure is the one used for cross-reference and derating calculations. It is suited for 145 V bus protection in automotive and telecom equipment where the board sees the full temperature range. ## Active production and ordering posture Sourced through authorized and independent distribution channels. The Tape & Reel packaging suits automated pick-and-place assembly.","metaTitle":"Vishay 1.5SMC170AHM3_A/I TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC170AHM3_A/I automotive TVS diode, 1500W peak pulse, 145V standoff, DO-214AB (SMC).
