Taiwan Semiconductor 1-Element Uni-Directional TVS Diode 1.5 kW Peak Pulse Power 2-Pin DO-201 1V5KE400A

Taiwan Semiconductor 1V5KE400A is a 1-element uni-directional transient voltage suppressor (TVS) diode designed for robust transient voltage protection in electronic circuits. It provides a peak pulse power dissipation of 1.5 kilowatts at 1 ms, effectively clamping voltage spikes and protecting sensitive components from surges and transient events.

The diode features a single-element configuration optimized for uni-directional surge protection applications. Its minimum breakdown voltage of 420 V and maximum reverse stand-off voltage of 342 V make it suitable for a range of moderate voltage systems. The robust DO-201 through-hole package ensures easy integration into hardware assemblies with dimensions measuring 9.5 mm length and 5.6 mm diameter.

It offers excellent electrical performance with a clamping voltage of 548 V and maximum peak pulse current of 2.8 A. The device operates reliably in wide temperature ranges from -55°C to 175°C, making it ideal for industrial, commercial, and automotive electronics applications where temperature extremes occur. Additionally, it maintains a low maximum reverse leakage current of 5 µA, contributing to power efficiency and circuit stability.

Key technical highlights include UL certification (UL #E210467), glass-passivated junction for enhanced durability, and compliance with FBI standards. These diodes are widely used in power supply circuits, telecommunication equipment, and other sensitive electronic devices requiring protection from voltage transients.

Typical use cases encompass industrial electronics manufacturing, laboratory circuit protection, HVAC controls, automotive electrical systems, and general-purpose electronic equipment safeguarding.
