The 20 V minimum breakdown rating is the turn-on threshold; with 18 V typical standoff and 20 V minimum breakdown, this part covers the 18–29.2 V protection window in a single bidirectional channel. ## Automotive qualification and thermal margin AEC-Q101 qualification means the part passed the temperature cycling, mechanical shock, and humidity bias tests required for engine-compartment and body-electronics deployments.","metaTitle":"Eaton 5-0SMDJ18CAH TVS Diode, 5kW 29.2V","metaDescription":"Eaton Zener TVS, 5000W peak pulse, 29.2V clamping @ 171A, 18V standoff.
