Clamping is specified at 77 V maximum at the 20 A peak pulse current (10/1000 µs waveform). That 77 V ceiling protects downstream electronics rated for 80 V or higher — a common margin for automotive load-dump and inductive kickback events. Rated for continuous junction operation from -55°C to 175°C. The 175°C Tj(max) is the standard for automotive-grade passives — it covers under-hood ambient plus self-heating from repetitive surge events without derating the peak pulse power. The 20 A Ipp at the 10/1000 µs waveform corresponds to a 1.5 kW peak pulse; repeated events at lower duty cycles are acceptable within the junction temperature envelope. Taiwan Semiconductor continues to produce the 1.5KE series in the DO-201 package. The 1.5KE family is a standard JEDEC DO-201 package, so parametric equivalents from other AEC-Q101-qualified suppliers exist — confirm the standoff and clamping targets before substituting.","metaTitle":"1.5KE56AHA0G TVS Diode, 1.5kW, 77V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE56AHA0G Zener TVS, 1500W peak pulse, 47.8V standoff, AEC-Q101.
