The single bidirectional channel handles positive and negative surges in one package, saving board space versus two unidirectional parts back-to-back. ## Clamping current and thermal margin Peak pulse current is 38A into the 41.4V clamp — at 1500W the part absorbs the surge without exceeding the junction temperature rating of 175°C. The wide operating range from -55°C to 175°C means the derating curve stays flat across most industrial ambient conditions; only above 25°C does the peak power need linear reduction per the datasheet's thermal impedance graph. Through-hole DO-201AA (DO-27 axial) package with bulk packaging — the lead-formed body suits point-to-point wiring on terminal blocks or PCB through-hole layouts where a surface-mount TVS would not handle the same surge energy without a larger copper pad. ## Active production and sourcing posture The 1.5KE series is a standard-pinout TVS family, so the 1.5KE30CA B0G is interchangeable with other manufacturers' DO-201 bidirectional 30V TVS diodes at the BOM level, provided the clamping voltage and peak pulse power match. No minimum order threshold beyond the reel or bulk pack increment.","metaTitle":"1.5KE30CA B0G TVS Diode, 1500W, 25.6V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE30CA B0G bidirectional Zener TVS, 1500W peak pulse, 25.6V reverse standoff, 41.4V clamp.
