That means it can be replaced on a board with a soldering iron and basic hand tools — no hot-air station or reflow profile needed. The axial leads are clearly polarised (cathode band), so orientation is straightforward even without a schematic in hand. ## Wide temperature range for industrial gear The 1500W pulse rating holds across that range, though derating applies above 25°C ambient per the standard power-temperature curve for axial TVS devices.","metaTitle":"1.5KE250A R0G TVS Diode, 1.5kW, DO-201, Taiwan Semi","metaDescription":"1.5KE250A R0G Zener TVS diode from Taiwan Semiconductor, 1500W peak pulse power, 214V standoff, 344V clamp.
