Breakdown voltage starts at 25.65V minimum, so a 24V bus that sees a 26V transient begins to clamp before the surge reaches the protected load. The 37.5V clamp ceiling limits the voltage stress on downstream semiconductors. The DO-201 body with tin-plated copper leads handles the thermal pulse of a 1500W event without exceeding the junction rating.","metaTitle":"Comchip 1.5KE27A-G TVS, 1.5kW, 23.1V Standoff, DO-201","metaDescription":"Active 1500W TVS diode, Zener type, 23.1V reverse standoff, 37.5V clamp.
