The 23.1 V standoff means the diode draws negligible leakage below that level; the 37.5 V clamp limits the spike seen by the downstream circuitry. ## DO-201AE axial — through-hole mounting and thermal path The DO-201AE axial package (also known as R-6) is a through-hole form factor with a 0.052-inch diameter lead. The body-to-lead thermal path conducts heat from the junction into the PCB copper; the lead length and solder fillet area determine the effective thermal resistance in the application. The junction temperature derates the peak pulse power above 25°C per the datasheet curve; at 175°C the 1500 W rating is derated to zero, so the ambient temperature and duty cycle must be factored into the surge budget. ## Active lifecycle — no obsolescence gate for new BOMs The single bidirectional channel (no polarity marking needed) simplifies inventory and placement: one part number covers both positive and negative transient clamping on a signal pair.","metaTitle":"1.5KE27CA-TP Micro Commercial Co TVS Diode, 1500W, DO-201AE","metaDescription":"1.5KE27CA-TP bidirectional Zener TVS diode, 1500W peak pulse power, 23.1V standoff, 37.5V clamp.
