That 14.5 V ceiling is the number that protects whatever load sits behind it — any downstream rail or signal line must survive a 14.5 V clamp without damage. 1500 W peak pulse power means the part absorbs up to 1.5 kJ of transient energy in a single 10/1000 µs event — the standard IEC 61000-4-5 surge waveform. This rating is the design gate for secondary protection on power rails, communication lines, and I/O ports in industrial controls, instrumentation, and telecom equipment where inductive transients or AC line faults are expected. ## DO-201AA axial — through-hole mounting and board assembly The DO-201AA (also called DO-27) axial lead package mounts in through-hole fashion — both leads exit the board and are typically clinched or wave-soldered for mechanical robustness. This form factor suits board-level protection on panels and backplanes where a through-hole part carries better mechanical retention than an SMD chip under vibration or thermal cycling. ## 175°C junction temperature — high-ambient deployment The junction temperature rating of -55°C to 175°C places this part in the high-temperature grade category — well above the 150°C typical for commercial TVS diodes. The upper bound matters in enclosed equipment or outdoor cabinets where ambient can reach 85°C and self-heating from clamping events adds to the thermal budget. At 175°C max Tj, the part retains protection margin in environments where a lower-rated TVS would derate or go into thermal runaway. The 1.5KE supplier device package designation ties this part to the 1.5 kW TransZorb series — the same thermal and surge-energy envelope as the rest of that series, with different stand-off voltages available across the range to match the protected rail. The base product number 1N6271 anchors the part within the standard 1N627x unidirectional TransZorb series — the A suffix designates the unidirectional polarity variant. Cross-checking any alternate stand-off voltage within the same series for BOM second-sourcing is the only available hedge against a future allocation event.","metaTitle":"Vishay 1N6271A-E3/54 TVS Diode, 1500W 14.5V Clamp","metaDescription":"Vishay 1N6271A-E3/54 unidirectional TVS diode, TransZorb series, 8.55V standoff, 14.5V clamping, 1500W peak pulse.
