The DO-201AA (DO-27) axial-lead package handles the thermal pulse of a 1500 W surge without secondary heat sinking, relying on the lead wire and PCB copper for thermal relief. ## Voltage ratings and the clamping ceiling Three voltage numbers define the protection window: reverse standoff (214 V typ), breakdown (237 V min), and clamping (344 V max at Ipp). The gap between standoff and breakdown is the margin the rail has before the diode starts conducting leakage current — a 200 V nominal bus sits comfortably below the 214 V standoff with no DC bias penalty. The 344 V clamp ceiling is the hard limit the downstream components must survive. For a 240 VAC rectified bus (≈340 VDC peak), the clamp voltage sits just above the normal peak, so the TVS only activates on genuine transients above the line crest. The through-hole DO-201 package suits point-to-point wiring on terminal blocks, high-reliability MIL-spec boards, or power supply output stages where a surface-mount TVS would struggle to dissipate the pulse energy into the PCB copper. ## Active production — sourcing posture No pin-compatible successor or cross-reference is recorded — the 1.5KE series is the current generation. For a BOM line already qualified to the DO-201 footprint, this is the direct order code.","metaTitle":"1.5KE250A B0G TVS Diode, 1500W, 214V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE250A B0G Zener TVS, 1500W peak pulse, 214V reverse standoff, 344V clamping.
