Housed in a DO-201AA (DO-27) axial-lead package, the diode is through-hole mounted and suited for point-of-use transient suppression on power entry boards or distribution panels. The 1.5KE series footprint is standard across the family, so a single PCB layout accommodates multiple voltage ratings.","metaTitle":"1.5KE56A-E3/54 Vishay TVS Diode, 1500W, 77V Clamp, DO-201AA","metaDescription":"Vishay 1.5KE56A-E3/54 TransZorb TVS diode, 1500W peak pulse, 77V clamping, unidirectional, DO-201AA axial.
