Clamping voltage and breakdown margin for 48V rails
The 1.5KE62CAHE3_A/C: Minimum breakdown voltage is 58.9 V, with the 53 V reverse standoff providing a 5.9 V margin before the device starts conducting leakage current — sufficient for 48 V nominal bus transients without false triggering. The 85 V clamping voltage at 17.6 A peak pulse current limits the voltage seen by downstream components during a surge event, protecting sensitive ECUs and sensors on the same supply rail.
