For a 24 V or 48 V automotive bus, the 85.5 V reverse standoff means the diode does not conduct during normal operation; only when the transient exceeds the 95 V minimum breakdown does it clamp, limiting the spike to 137 V maximum while shunting up to 11.4 A of peak pulse current. Because it is bidirectional, a single device protects both positive and negative transients — useful on AC-coupled data lines or bipolar power rails where polarity is not fixed. The 10/1000 µs waveform is the industry-standard pulse for TVS characterization; if your application's transient is shorter (8/20 µs, for example), the peak power capability is higher, but the 1.5 kW figure at 10/1000 µs is the conservative anchor for derating. ## Automotive qualification and temperature envelope AEC-Q101 qualification places this part in the automotive-grade bin — it has passed the stress tests (temperature cycling, high-temperature reverse bias, ESD) required for under-hood and passenger-compartment electronics. The DO-201AA axial package is a through-hole format with a 0.052-inch lead diameter — it inserts into a 0.040-inch plated through-hole and is wave-soldered. The axial leads carry the full 11.4 A pulse current without fusing, but the PCB trace width between the TVS and the protected rail must be sized for that peak current (at least 50 mils of 1 oz copper per the IPC-2221 derating). The supplier device package is DO-201, which is the same body as the DO-27; both are interchangeable for footprint purposes. ## Active lifecycle and sourcing posture The base product number is 1.5KE100, and the suffix CAHA0G encodes the bidirectional polarity (CA), the automotive grade (HA), and the packaging (0G for Tape & Box). If the design requires an unidirectional version, the 1.5KE100A variant is the same family with a single-direction die; if a different package is needed, the SMCJ series offers a surface-mount alternative, though the pinout and thermal path differ.","metaTitle":"1.5KE100CAHA0G TVS Diode, 1.5 kW, 85.5 V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE100CAHA0G bidirectional Zener TVS, 1500W peak pulse, AEC-Q101 automotive grade, DO-201 axial.
