That means it carries the full automotive reliability testing — temperature cycling, high-temperature reverse bias, and ESD qualification — so an ECU or sensor module using this part meets the PPAP documentation threshold an OEM auditor expects. At the high end, that covers underhood ambient plus self-heating from the 1500W peak pulse — the die junction stays within the rated SOA even during a load-dump transient on a 24V truck line. Production status is Active. The part ships from the factory — no last-time-buy or NRND flag. ## Clamping voltage and peak pulse current — sizing the protection Reverse standoff voltage is 145V. For a 24V automotive bus with a 150V max transient per ISO 7637-2 pulse 5a, this TVS clamps the surge to 234V — which keeps the downstream DC-DC converter's input FET within its 250V Vds rating. Peak pulse power is 1500W for a 10/1000 µs exponential waveform. The 6.7A peak current is the maximum the diode can handle at that pulse width; shorter transients (like 8/20 µs ESD) allow much higher current, but the 10/1000 µs rating is the standard for automotive load-dump and surge testing. ## DO-201 axial package — board integration Supplied in a DO-201AA / DO-27 axial-leaded package, through-hole mounted. The two axial leads handle the 6.7A peak pulse current with minimal inductive voltage drop; the body diameter is standard for a 1500W TVS and fits a 1.0 mm diameter hole in the PCB. Packaged in Tape & Reel (TR), suitable for automated insertion. The base product number is 1.5KE170; the 'CAH' suffix indicates bidirectional and Automotive grade.","metaTitle":"1.5KE170CAH TVS diode, 1500W, AEC-Q101, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE170CAH bidirectional TVS, 1500W peak pulse, AEC-Q101 qualified, 145V standoff, DO-201 package.
