1500 W bidirectional TVS for 145 V rails
The 1.5KE170CAHB0G: It clamps transients at 234 V max and handles 6.7 A peak pulse current, making it a fit for protecting 145 V nominal DC rails in automotive and industrial power systems.
Automotive-grade qualification means the temp range and reliability tests
AEC-Q101 qualification certifies the diode for automotive stress levels: high-temperature reverse bias, power cycling, and ESD robustness. The DO-201AA axial package suits through-hole mounting on power entry boards or bus bars where a surface-mount part would risk solder-joint fatigue under thermal cycling. The 1500 W rating is derated above 25°C per the datasheet curve — at 175°C junction the peak pulse capability drops to roughly 25% of the 25°C value.
