1500W peak pulse clamping for 128V rails
The 1.5KE150CAH: It clamps transients at 207V maximum when the protected rail sits at 128V reverse standoff — the gap between standoff and breakdown (143V min) gives the circuit normal operating margin without nuisance clamping.
Package and board integration
Through-hole DO-201AA (DO-27) axial package, supplier device package DO-201. The axial leads suit point-to-point wiring on terminal strips or through-hole PCB layouts — hand-solderable without special equipment. The 7.6A peak pulse current at the clamping voltage means the lead cross-section and solder joint carry the surge without fusing. Tape and reel packaging is standard for the 1.5KE series, though the through-hole format means reel quantities are typically lower than surface-mount reels. The base product number is 1.5KE150; the 'CAH' suffix denotes bidirectional and automotive grade.
