When a surge drives the line above the 61.2 V breakdown minimum, the device clamps the voltage to 98 V maximum at the rated peak pulse current of 16 A (10/1000 µs waveform). That 98 V ceiling is the clamping level the downstream IC or fet must survive; the 1.5 kW peak pulse rating confirms the diode can absorb the energy of the event without failing short. ## Automotive grade and AEC-Q101 qualification AEC-Q101 is the automotive discrete semiconductor stress qualification — it covers temperature cycling, humidity bias,ESD, mechanical shock, and vibration to the levels a vehicle-grade power node demands. For a telecom line-card application the grade is a proxy for robustness rather than a regulatory requirement, but it means the part has been characterised for the failure mechanisms (hot-carrier degradation, surge fatigue) that kill lesser TVS diodes over time.","metaTitle":"1.5SMC68H — 55V Zener TVS, 1.5kW, DO-214AB SMC","metaDescription":"Zener TVS diode, 55.1V standoff, 61.2V breakdown, 98V clamping at 16A.
