With a 20.5V reverse standoff voltage and a 22.8V minimum breakdown, this part clamps transients at 33.2V maximum while conducting 47A peak pulse current. The 6.7V gap between standoff and clamp means a 24V nominal rail sees the TVS start conducting around 23V and hold the line below 34V — clean protection for sensitive downstream silicon. ## Automotive-grade qualification and deployment context The DO-201AA axial-lead package is a through-hole form factor — hand-solderable on a perfboard or wave-solderable in production. The 1.5KE series footprint is standard across the TransZorb family, so a board layout for a 1.5KE24A (unidirectional) takes this bidirectional variant with the same pad geometry.","metaTitle":"1.5KE24CAHE3_B/C Vishay TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE24CAHE3_B/C TransZorb TVS, 1500W peak pulse, 20.5V standoff, AEC-Q101 automotive grade.
