Breakdown starts at 20.9 V minimum, and clamping maxes at 30.6 V at the full 49.7 A pulse. That 30.6 V clamp is what the downstream silicon sees; if the protected IC's abs-max is 32 V, there is about 1.5 V of margin at the worst-case pulse. ## DO-201 axial — field-swap friendly Through-hole DO-201AA / DO-27 axial package. Polarity is marked by the cathode band — no orientation guesswork on a board rework. Can be swapped on site with basic hand tools; no hot-air station needed.","metaTitle":"YAGEO 1.5KE22A/B Zener TVS, 1500W, DO-201, Active","metaDescription":"YAGEO 1.5KE22A/B Zener TVS diode, 1500W peak pulse, 18.8V standoff, 30.6V clamp, DO-201 axial.
