Breakdown is guaranteed between 14.3 V and the clamping ceiling, so a 24 V supply bus is outside the safe operating window for this part; it is sized for nominal 12 V systems. The single unidirectional channel protects one signal or power line. ## DO-201AA axial — through-hole mounting note Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE15A-/54 is a through-hole device. The lead bend radius and hole diameter on the PCB must follow Vishay's recommended footprint to avoid stress cracks in the glass passivation — the same package used across the 1.5KE series, so a single board layout serves multiple voltage variants. ## TransZorb series — what the name signals Vishay markets this as a TransZorb® TVS, its proprietary designation for a silicon-avalanche diode optimized for repetitive surge clamping. The series is rated for general-purpose circuit protection — no power-line-specific rating, so it is suited for DC rail and signal-line transient suppression rather than AC mains clamping.","metaTitle":"Vishay 1.5KE15A-E3/54 TVS, 1500W, 12.8V Standoff, DO-201AA","metaDescription":"Active Vishay 1.5KE15A-E3/54 TransZorb TVS diode, 1500W peak pulse, 12.8V reverse standoff, unidirectional, DO-201AA axial.
