The DO-214AB (SMC) surface-mount package delivers a low-inductance path to the PCB ground plane, critical for fast transient suppression. ## Sourcing posture for active automotive-grade TVS The product status is Active, meaning Vishay continues to manufacture this order code. For a BOM line protecting a 459V rail in an automotive ECU or telecom power supply, this part is a current-design-in candidate with no forced migration horizon.","metaTitle":"Vishay 1.5SMC540AHM3_A/I Zener TVS, 459V Standoff, 1500W","metaDescription":"Vishay 1.5SMC540AHM3_A/I Zener TVS diode, AEC-Q101, 459V reverse standoff, 740V clamp, 1500W peak pulse power.
