The minimum breakdown voltage is 95 V, so the device begins to avalanche at that threshold. Peak pulse current is 10.9 A at the clamping voltage, defining the maximum surge the part can absorb in a single event before the junction temperature exceeds the 175°C limit. ## Automotive qualification and deployment context This part carries AEC-Q101 qualification, the automotive discrete semiconductor stress test standard covering temperature cycling, high-temperature reverse bias, and ESD robustness. The -55°C to 175°C operating junction range suits under-hood and engine-bay environments where ambient temperatures exceed 125°C. The DO-201AA axial-lead package (also known as DO-27) is a through-hole form factor rated for the full 1500 W pulse. The leaded body dissipates heat through the PCB copper pads — the thermal path is through the solder joint and trace, not a heatsink.","metaTitle":"Vishay 1.5KE100CAHE3_A/C TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE100CAHE3_A/C TransZorb TVS, 1500W peak pulse, 85.5V standoff, 137V clamp, AEC-Q101, DO-201AA.
