The DO-201AA axial package (also known as DO-27) is through-hole, which means it survives rework cycles well — the leads take the heat, not the die. Pin 1 is the cathode band; orientation is unambiguous under a hot-air station or wave solder. For a 170V DC bus, that clamp gives about 60% headroom above the rail — enough margin for most downstream semiconductors rated at 300V or higher. The 5.7A peak pulse current is the current the diode shunts at the clamp voltage. In a real fault, the source impedance determines the actual current; this rating confirms the diode can handle the full 1500W pulse without failing short. The wide range also means derating at high ambient is predictable; at 125°C ambient the pulse power capability drops to roughly 75% of the 1500W rating, per standard Zener derating curves. ## Active production — sourcing and compliance The part is supplied in Tape & Box (TB) packaging, which is the standard bulk format for axial diodes — suitable for hand insertion or vibratory bowl feeders.","metaTitle":"1.5KE200A A0G TVS Diode, 1500W, 171V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE200A A0G Zener TVS diode, 1500W peak pulse power, 171V reverse standoff, 274V clamp.
