The 1.5KE200A is a unidirectional transient-voltage-suppressor (TVS) diode in a DO-27 axial package designed to protect circuits from high-energy transient overvoltages. It’s part of the 1.5KE series, rated for a 1500 watt peak pulse power capability (1 ms pulse) and constructed in a molded plastic case with a polarity band marking the cathode. The device is intended as a surge protection element that clamps harmful voltage spikes and redirects surge energy away from sensitive components.
The device is specified to have a nominal working standoff (VRWM) of 171 V and a controlled breakdown range (VBR) near 190–210 V (measured at the specified test current). Under the standardized 10×1000 µs surge waveform the part’s clamping voltage and pulse current characteristics are given so designers can predict the maximum voltage seen by protected circuitry during a surge. Thermal and soldering limits are stated to ensure reliable mounting and operation.
The datasheet emphasises fast response, low dynamic impedance and excellent clamping capability. It calls out high-temperature soldering capability (260°C, 10 s) and a wide operating temperature range (-55°C to +175°C), highlighting the part’s suitability where both electrical robustness and mechanical/thermal reliability are needed. Mechanical dimensions and lead length recommendations (0.375″, 9.5 mm) are provided for proper PCB mounting and heat-sinking practices.
Features:
- Plastic DO-27 package with UL 94V-0 flammability classification.
- 1500 W peak pulse capability (10 × 1000 µs waveform).
