The standoff voltage sets the maximum working DC rail the diode can guard without conduction — a 48V system needs a standoff above 48V; 64V gives the 33% headroom typical for transient protection. The clamping voltage, not the standoff, is what the protected load actually sees during an event. The peak pulse current spec governs the surge current the clamping characteristic can handle without degradation; exceeding it shifts the clamping curve and reduces clamping performance on subsequent events. ## Temperature grade and package fit The DO-214AB SMC package thermal path runs through the cathode tab to the PCB pad; adequate copper area under the device is required to keep the junction below 150°C under the rated pulse train. Marked as bidirectional with 1 channel — this is a single-polarity TVS that protects against positive overvoltage transients in one direction, not a symmetrical bidirectional clamp. Power line protection is flagged No, meaning it is not characterized for direct AC mains protection duty; it suits secondary-side protection on DC rails, signal lines, and low-power distribution nodes.","metaTitle":"1.5SMCJ64CA TVS Diode, 64V standoff, 103V clamp, 1.5kW","metaDescription":"Diotec 1.5SMCJ64CA unidirectional TVS diode in DO-214AB SMC. 64V standoff, 103V clamping, 1.5 kW peak pulse.
