Its 77 V maximum clamping voltage at 20 A peak pulse current (10/1000 µs waveform) is the figure that decides whether the protected rail stays within the downstream device's abs-max rating during a surge. The 77 V clamp means a 48 V bus sees a transient shunted to a peak well below the 80–100 V rating of most downstream POL converters. ## DO-201 axial — through-hole for high-energy clamping The operating junction temperature range spans -55°C to 175°C, covering industrial and outdoor enclosures where ambient heat plus self-heating from repetitive surges must be budgeted. ## Active production, no cross-reference on record No official successor or second-source cross-reference is listed — the base product number 1.5KE56 covers the family, and the A0G suffix denotes the Tape & Box packaging variant. For BOM positions requiring a 48 V standoff, 1500 W TVS in DO-201, this is the current-production choice.","metaTitle":"1.5KE56A A0G TVS Diode, 1500W, 77V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE56A A0G Zener TVS, 1500W peak pulse, 77V clamping, 20A Ipp. Active production, DO-201 axial.
