For an existing BOM line that calls out this exact part number, the sourcing path runs through independent distribution surplus or broker inventory. ## Key protection ratings and what they mean The minimum breakdown voltage is 380 V, and the clamping voltage at the 4 A peak pulse current is 548 V max. Single bidirectional channel means a single device protects both polarities — useful on AC signal or power lines where the surge can swing positive or negative. ## Package and board integration Housed in a DO-201AA / DO-27 axial-lead package, also referred to as the DO-201 supplier device package. The through-hole mounting is a manual-insertion process — no reflow profile to manage, but the axial leads need lead-forming for PCB or point-to-point wiring. Supplied on Tape & Reel, which is atypical for an axial-lead part — the reel format suits automated insertion or kitting rather than bulk bag. Confirm the feeder or cut-tape requirement with your assembly house. The operating junction temperature range spans -55°C to +175°C, covering industrial and some military-grade thermal environments.","metaTitle":"1.5KE400CA-T Diodes Inc Zener TVS, 548V Clamp, Obsolete","metaDescription":"1.5KE400CA-T Diodes Inc bidirectional Zener TVS diode. 1500W peak pulse, 548V clamp, DO-201 package.
