That 15.8 V window between standoff and clamp defines the transient headroom: a 24 V nominal rail with 5 % tolerance sits safely below 25.6 V, and a surge that drives the line to 41.4 V is clamped before it reaches downstream silicon rated for, say, 45 V. ## 1500 W peak pulse — what the rating means for real surges The 1500 W peak pulse power is specified for a 10/1000 µs exponential waveform — the standard telecom surge shape. For shorter pulses (e.g. 8/20 µs from an ESD or lightning strike), the peak current capability is higher because the energy per pulse is lower. The DO-201 axial package dissipates this energy through the lead wires into the PCB copper; a 1 oz copper pad on each side of the board improves thermal spreading during repetitive surges. ## Through-hole DO-201 — board integration and temperature range The DO-201AA (DO-27) axial package measures about 9.1 mm body length with 0.96 mm diameter leads — standard for hand-insertion or wave-solder assembly.","metaTitle":"YAGEO 1.5KE30A/B TVS Diode, 1500W, 25.6V Standoff, DO-201","metaDescription":"YAGEO 1.5KE30A/B Zener TVS diode, 1500W peak pulse power, 25.6V reverse standoff, 41.4V clamp.
