A single unidirectional Zener channel, so it handles one polarity of transient. For bidirectional clamping on AC lines, two devices back-to-back or a dedicated bidirectional TVS is needed. ## Through-hole axial — DO-201AA footprint Supplied in a DO-201AA (DO-27) axial-lead package, through-hole mount. The DO-201 body handles the 1.5 kW pulse without cracking the epoxy — the lead diameter and body length are standard for this power class. Tape-and-reel packaging suits automated insertion for volume builds. No power line protection feature — the part is a bare TVS diode, not a filtered suppressor.","metaTitle":"1.5KE250A-T Diodes Zener TVS, 1.5kW 344V Clamp","metaDescription":"1.5KE250A-T by Diodes Inc — obsolete Zener TVS, 1500W peak pulse, 344V clamping, DO-201.
