A single bidirectional channel handles symmetrical clamping in both polarities, eliminating the need for back-to-back series diodes in AC or bipolar DC lines. ## Temperature range and package Housed in a DO-201AA (DO-27) axial leaded package for through-hole mounting on boards or terminal strips where surface-mount TVS would risk solder joint fatigue under vibration. ## Lifecycle and procurement Sourced to order against an RFQ; availability and date-code provenance confirmed at quote time.","metaTitle":"1.5KE33C-E3/54 Vishay TransZorb TVS, 1500W, 26.8V Standoff","metaDescription":"Vishay 1.5KE33C-E3/54 TransZorb bidirectional Zener TVS, 1500W peak pulse, 26.8V standoff, DO-201AA.
