Clamping performance for transient suppression
The 1.5SMC62CA R7G: The 53V reverse standoff rating defines the working voltage at which the device stays off in normal operation; the 58.9V breakdown minimum is where conduction begins when a transient exceeds that threshold. At the peak pulse condition, the clamping voltage is held to 85V maximum, protecting downstream circuits from the full surge voltage.
Temperature grade and SMT form factor
Junction temperature, not ambient, is the constraint; thermal resistance from junction to ambient (θJA) in the DO-214AB package governs how quickly the die approaches 150°C under sustained surge load. Surface-mount DO-214AB (SMC) package accepts standard reflow profiles and is compatible with standard SMT board assembly; the tape-and-reel packaging supports high-volume pick-and-place.
Series positioning and base part number
The 1.5SMC series is Taiwan Semiconductor's 1500W peak-pulse-power TVS family in the DO-214AB package. The base number 1.5SMC62 references the 62V nominal Zener voltage class — variants across the series offer different standoff voltages to match specific rail protection and compliance.
