Applications
The 1.5KE200A is designed to protect sensitive electronic circuits from high-voltage transients on AC and DC power lines operating around 170 V to 200 V. It is commonly used on the secondary side of industrial power supplies, telecommunications line cards, and motor drive interface circuits to absorb surge energy from lightning strikes or load switching events. The 1500 W peak power rating makes it appropriate for environments where high-energy transients occur repeatedly.

Frequently Asked Questions
What peak pulse power and clamping voltage does the 1.5KE200A provide during a transient event?
The 1.5KE200A absorbs up to 1500 W of peak pulse power during a 10/1000 µs surge waveform. Its maximum clamping voltage is 353 V at peak pulse current, with a nominal breakdown voltage of 200 V and a tight tolerance band of 190 V to 210 V, ensuring predictable overvoltage limiting for downstream components rated above 353 V.
Which industrial or telecom applications benefit most from the 1.5KE200A's 200 V rating?
The 1.5KE200A is well suited for protecting I/O signal lines on industrial PLCs, motor drive interfaces, and telecom line cards that operate on 170 V to 200 V rails. Its 1500 W peak power capability handles repetitive surges from load switching, while the DO-201 axial package allows easy through-hole integration into dense power board layouts.
How does the 1.5KE200A's breakdown voltage range compare to the bidirectional 1.5KE200CA for AC line protection?
The 1.5KE200A is unidirectional with a breakdown voltage of 190 V to 210 V and a 353 V clamping voltage, suitable for DC rail protection. The bidirectional 1.5KE200CA shares the same 1500 W peak power and 200 V nominal breakdown but conducts in both polarities, making it the preferred choice for AC line clamping where both half-cycles must be suppressed. Both are offered in the same DO-201 package with 675 pF typical diode capacitance.
