TVS DIODE 1.5KE200A Unidirectional 274V 5.47A

Description

1.5KE200A TVS DIODE Unidirectional 274V 5.47A 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). Excellent clamping capability. Low dynamic impedance. Fast response time (typically listed as very fast from 0 V to VBR for unidirectional). Typical reverse leakage (IR) low (document notes very small µA levels above certain voltages). High-temperature soldering guaranteed (260°C / 10 s with specified lead length and tension). Molded plastic case; polarity marked by color band.
