1500 W peak pulse in a DO-201 axial package
The 1.5KE16CAH: It clamps transients at 22.5 V maximum while conducting 70 A peak pulse current, making it a fit for protecting 12 V and 13.6 V nominal rails in automotive and industrial DC buses. The DO-201AA (DO-27) axial-lead package suits through-hole assembly on boards or terminal strips where a robust mechanical anchor is preferred over surface-mount. The 1.5KE series is a standard footprint for TVS diodes in this power class.
Automotive-grade clamping with AEC-Q101 qualification
The breakdown voltage range starts at 15.2 V minimum, ensuring the diode begins conducting before the protected circuit sees a damaging overvoltage. Reverse standoff is 13.6 V, so a 12 V nominal rail with 10% tolerance (13.2 V max) stays below the standoff level during normal operation. No power-line protection rating confirms this is a signal or secondary-side rail protector, not a primary AC mains suppressor.
Active lifecycle and sourcing posture
For BOM placement, the Tape & Reel packaging is the standard procurement format for volume assembly. The base product number 1.5KE16 identifies the electrical rating; the 'CAH' suffix denotes the automotive-qualified bidirectional variant.
