The 1.5SMC62CA_R1_00001 is a unidirectional Zener-based transient voltage suppressor — the bidirectional variant sits in the same SMC footprint as the single-direction part and clamps across both polarities, so it protects AC signal lines and push-pull circuits where the polarity flips with line state. Reverse standoff is 53 V nominal — this is the working voltage the protected rail can sit at continuously without the TVS conducting. The breakdown minimum of 58.9 V sits above it, so the part stays off under normal operation and the clamping voltage of 85 V max limits what the downstream load sees during a surge event. In practice the clamping voltage of 85 V at that current means the TVS dissipates roughly 1.5 kW for the surge duration, well within the 1.5 kW rating.
This is the key selection check for outdoor power supplies and industrial converters where ambient can reach 85 °C and the thermal resistance of the SMC package drives the actual margin at full surge. Operating temperature is specified at the junction, not ambient — the board designer must work back from the thermal resistance of the DO-214AB solder pad to confirm Tj stays within limit during a repeated-surge event.
Tape-and-reel SMC for high-volume pick-and-place
CT strips serve low-quantity prototype builds without committing to a full reel. The DO-214AB (SMC) package has a body width of approximately 6.1 mm — board clearance must account for the foot pad and any adjacent component spacing required by the layout's creepage rules at the working voltage.
