1500W peak pulse in a bidirectional axial package
The 1.5KE18CH: It clamps transients at 26.5 V maximum while conducting 59 A of peak pulse current (10/1000 µs waveform). 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.
