Product Description
STMicroelectronics 1.5KE250A Uni-Directional TVS Diode is a high-performance transient voltage suppressor designed to protect electronic circuits from voltage surges and transient pulses.
This 1-element diode features a peak pulse power dissipation of 1.5 kW and comes in a through-hole compatible DO-201 package with 2 pins, providing reliable and robust clamping for sensitive electronic components.
The diode configuration is single and uni-directional, optimized for applications requiring unidirectional voltage transient protection. Its minimum breakdown voltage of 237 V and maximum reverse stand-off voltage of 213 V make it especially suitable for industrial electronics and power supply circuits operating within these voltage levels.
The device can operate reliably in harsh environments with a temperature range from -65°C to 175°C, ensuring durability and stability under thermal stress. The maximum peak pulse current (Ippm) of 23 A allows the diode to clamp high surge events effectively, protecting downstream circuitry.
Compact dimensions (length 9.5 mm, diameter 5.3 mm, height 5.3 mm) allow integration into densely packed PCB layouts. Additionally, the maximum reverse leakage current is only 1 μA, minimizing leakage losses when the diode is in standby.
Single diode with uni-directional voltage suppression configuration. Peak pulse power rating of 1.5 kW for surge protection. Through-hole mounting with DO-201 package for ease of installation. Suitable for industrial, power supply, and electronic protection applications.
Wide operating temperature range supports harsh environmental conditions. High peak pulse current capacity safeguards sensitive electronics. Low reverse leakage current maximizes efficiency in standby modes. Compact axial package suitable for automated PCB assembly.
This TVS diode is ideal for protecting discrete semiconductor circuits in industrial, electrical, and electronic component assemblies. Its high pulse power rating and superior transient protection capabilities make it excellent for manufacturing environments and laboratory test setups.
