The 1.5KE20AHE3_A/C: Reverse standoff voltage is 17.1 V, breakdown minimum 19 V, and the clamping voltage at peak pulse current (54.2 A) is 27.7 V — the protection window stays below the 36 V abs-max of most 12 V-rated ECUs. The DO-201AA axial package fits standard through-hole mounting on a double-layer board; the 1.5 kW rating is derated linearly above 25 °C per the datasheet curve.
Yes, it is part of the Automotive, AEC-Q101, TransZorb series, meaning it meets the automotive-grade reliability and stress-test requirements for use in vehicle electronics.
