Breakdown starts at 237 V min, and clamping holds at 344 V max at the 4.5 A peak pulse current (10/1000 µs waveform). The 4.5 A peak pulse current rating is the current at which the clamping voltage is specified — the actual surge capability is defined by the 1500 W peak pulse power, which covers higher currents at lower clamp voltages. ## DO-201 axial package — board-fit note Tape-and-reel packaging is standard for automated insertion; the axial leads require the correct feeder pitch on the insertion machine.","metaTitle":"1.5KE250CAH TVS Diode, 1500W, 214V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE250CAH bidirectional TVS diode, 1500W peak pulse, 214V standoff, AEC-Q101 automotive grade.
