The 1.5KE body diameter and lead spacing are standard for this power class — the leads are tin-plated copper, solderable in wave or hand-solder processes. No power line protection means it is a unidirectional clamp for signal or DC supply rails, not an AC mains protector.","metaTitle":"1.5KE22-E3/54 Vishay TransZorb 1500W TVS, DO-201AA","metaDescription":"Vishay 1.5KE22-E3/54 Zener TVS diode, 1500W peak pulse, 17.8V standoff, 31.9V clamp.
