Breakdown occurs at a minimum of 34.2V, and the clamping voltage at peak pulse current is 64.3V. That 64.3V ceiling is what the downstream circuitry must survive — if the protected device has a 60V absolute maximum, this part leaves only 4.3V of margin, so verify the load's voltage tolerance against the clamping spec. ## Surge current and waveform context The peak pulse current is listed as 62A for an 8/20µs waveform, which is the standard IEC 61000-4-5 surge shape. For the longer 10/1000µs telecom waveform the peak current will be lower — the 600W rating is the energy envelope. When sizing the TVS for a specific transient test, match the waveform to the datasheet's derating curves. No power line protection feature is built in — this is a basic TVS, not a combination protector.","metaTitle":"STMicroelectronics SM6T36AY TVS Diode, 600W, AEC-Q101","metaDescription":"STMicroelectronics SM6T36AY automotive AEC-Q101 Zener TVS diode. 600W peak pulse power, 30.8V standoff, 64.3V clamping.
