ON Semiconductor NUP4114 ESD Protection Diode, SC-88, 5.5V

The ON Semiconductor NUP4114 is a high-performance ESD (Electrostatic Discharge) protection diode designed to safeguard sensitive electronic circuits. Engineered with a very low clamping voltage of 10V maximum, it effectively diverts dangerous transient voltage spikes away from critical components, preventing damage and ensuring long-term reliability. This device offers a 5.5V stand-off voltage and features exceptionally low leakage current, making it highly efficient for protecting low-voltage signal lines.

A key advantage is its ultra-fast response time, typically less than 1.0 nanosecond. This rapid reaction ensures that damaging ESD events are suppressed before they can harm the protected circuitry. The diode is qualified to meet the rigorous IEC61000-4-2 Level 4 standard for ESD immunity, providing robust protection against the most severe electrostatic discharges encountered in real-world environments.

Quality and Applications

Fully AEC-Q101 qualified and PPAP capable, this component is specifically designed for the demanding requirements of the automotive industry. Its reliability makes it an excellent choice for protecting infotainment systems, control modules, sensor interfaces, and communication buses (like CAN, LIN) in vehicles. It is also perfectly suited for a wide range of consumer electronics, industrial controls, and communication devices where data integrity and component longevity are paramount.

Housed in a compact SC-88 surface-mount package with 6 pins, it facilitates easy integration into high-density PCB layouts. The combination of low clamping voltage, fast response, and automotive-grade qualification makes the NUP4114 a trusted solution for engineers seeking robust, space-efficient ESD protection.
