For a 171V reverse standoff, the diode stays off during normal DC rail operation up to 171V, then activates only when a surge exceeds that level. ## Unidirectional channel and temperature range Single unidirectional channel — cathode band on the DO-201AD axial package — so it protects one polarity rail. The through-hole DO-201AD body handles the thermal pulse of a 1500W surge without delaminating.","metaTitle":"1.5KE200A Zener TVS Diode – onsemi Mosorb™, 1500W, DO-201AD","metaDescription":"onsemi 1.5KE200A Zener TVS diode, 1500W peak pulse power, 190V breakdown, DO-201AD axial.

Submit an RFQ with your target quantity; we confirm availability and current pricing at quote time."},{"question":"What is the replacement for the 1.5KE200A?","answer":"The evidence does not list an official onsemi successor. For a pin-compatible drop-in, look at the same 1.5KE series with a 200V breakdown rating — for example, the 1.5KE200A from other manufacturers like Vishay or Littelfuse, which share the DO-201AD package and 1500W rating.
