The 14.5 V reverse standoff voltage means it stays transparent on a 12 V nominal rail, only clamping when the line exceeds the 16.2 V minimum breakdown threshold. This is the typical fit for 12 V automotive battery lines, sensor supplies, or any unregulated bus where load-dump and ISO 7637-2 transients are expected. ## Automotive-grade transient protection across temperature The DO-201AA (DO-27) axial-lead package suits through-hole board assembly — the body is rated for the full 1500 W pulse without derating at 25°C ambient. ## Active production — quoted per BOM line Tape & Reel packaging (TR) is standard for axial diodes, suitable for automated insertion.","metaTitle":"1.5KE18CH TVS Diode, 1500W, 14.5V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE18CH bidirectional Zener TVS, 1500W peak pulse, 14.5V reverse standoff, AEC-Q101 automotive grade.
