For a protected rail rated at 300 V nominal, this clamping margin keeps the downstream semiconductor stress below typical 500 V abs-max ratings. The 1500 W peak pulse rating uses the standard 10/1000 µs double-exponential waveform — a shorter transient (e.g. 8/20 µs) allows higher peak current; a longer surge requires derating. The 3.2 A Ipp at the clamp voltage confirms the diode can absorb the energy of a typical 300 V rail surge without exceeding the junction temperature limit of 175 °C. ## Through-hole package and board integration The DO-201AA (DO-27) axial leaded package requires a 1.0 mm diameter hole on a 0.100-inch pitch and is typically wave-soldered. The bulk packaging and through-hole format suit high-reliability power supplies, motor drives, and battery-management boards where the TVS is hand-inserted or auto-inserted on a leaded line. No power line protection feature is built in — this is a pure transient suppressor, not a reverse-polarity or overcurrent device.","metaTitle":"1.5KE350CAHB0G TVS Diode, 1500W, 300V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE350CAHB0G bidirectional TVS, AEC-Q101 automotive, 1500W peak pulse, 300V standoff, DO-201 axial.
