This is a unidirectional device — the cathode band on the DO-201 package marks the grounded side. Bidirectional protection requires two diodes or a different part number from the same series. Rated for junction temperatures from -55 °C to 175 °C, this TVS covers the full industrial and automotive under-hood thermal profile. The wide operating range means it can be placed on a hot PCB near a switching regulator or in an outdoor enclosure without derating concerns. For BOM planning, the base product number 1.5KE30 covers the full family, with the R0G suffix denoting Tape & Reel packaging.","metaTitle":"TSC 1.5KE30A R0G TVS Diode, 1.5 kW, 25.6 V Standoff","metaDescription":"Taiwan Semiconductor 1.5KE30A R0G Zener TVS diode, 1500W peak pulse power, 25.6V reverse standoff, 41.4V clamping.
