Availability and date-code spread are confirmed at RFQ against the specific lot. ## Clamping parameters and the protection envelope This defines the protection window for a 48V nominal bus — the TVS stays transparent below 43.6V and clamps transients before they exceed 70.1V. The single bidirectional channel means a single device protects both polarities on the same line, saving board space compared to back-to-back unidirectional parts. ## Package and board fit Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE51CA-T is a through-hole part. The DO-201 footprint is standard and mates with existing board layouts for this power class.","metaTitle":"1.5KE51CA-T Diodes Inc TVS, 1500W Bidirectional, DO-201","metaDescription":"1.5KE51CA-T Diodes Incorporated Zener TVS, 1500W peak pulse, 43.6V standoff, bidirectional, DO-201.
