Nexperia Ultra Low Capacitance Bidirectional Double ESD Protection Diode, SOT-1

The Nexperia PESD5V0U2BT,215 is an ultra-low capacitance, bidirectional double ESD protection diode engineered to safeguard sensitive electronic components. It offers robust protection for two data lines against the damaging effects of electrostatic discharge (ESD), a common threat in manufacturing, handling, and operational environments. This component is critical for maintaining signal integrity and preventing costly failures in high-speed data applications.

A standout feature is its exceptionally low diode capacitance of just 2.9pF. This ultra-low value minimises signal distortion and attenuation, making it ideal for protecting high-speed data interfaces without degrading performance. It is paired with a remarkably low leakage current of 5nA, ensuring power efficiency and reliability in low-power circuits.

The diode provides formidable ESD protection, rated up to 10kV according to the IEC 61000-4-2 Level 4 standard. This high level of immunity makes it a reliable defence against transient voltage spikes. Housed in a compact SOT-23 (TO-236AB) surface-mount package, it is designed for space-constrained PCB layouts common in modern portable and miniaturised electronics.

Key Applications

This versatile protection diode is suitable for a wide array of electronic systems. It is commonly used in computers and peripherals, audio/video equipment, and cellular handsets and accessories. Its performance characteristics make it perfect for 10/100/1000 Ethernet ports, Local Area Network (LAN) equipment, and general communication systems. It is also well-suited for portable electronics, SIM card protection, FireWire interfaces, and other high-speed data line applications.
