ON Semiconductor SRDA05-4R2 - Steering/TVS Diode Array

The SRDA05-4R2 from ON Semiconductor is a robust, high-performance steering diode/TVS (Transient Voltage Suppressor) array designed to protect multi-line and high-speed data interfaces. This component is specifically engineered to safeguard sensitive equipment from damaging overvoltage and electrostatic discharge (ESD) events, which are common threats in electronic devices. The SRDA05-4R2 is an ideal solution for applications requiring reliable and efficient protection with minimal signal distortion.

This versatile protection device features a low capacitance design, making it suitable for high-speed data lines such as USB 2.0, Ethernet, and other serial and parallel interfaces that require fast signal integrity. With a low clamping voltage and low leakage current, the SRDA05-4R2 ensures that the protected circuits maintain their performance while being shielded from harmful transients.

The SRDA05-4R2 comes in a compact SO-8 package, which allows for space-saving PCB design and is compatible with standard PCB assembly processes. Its small form factor does not compromise its protective capabilities, as it can handle ESD strikes up to the IEC61000-4-2 Level 4 standard, providing a high level of protection for sensitive components.

This device features four lines of protection, making it suitable for protecting multiple data lines with a single component. The bidirectional design of the SRDA05-4R2 means that it can protect against transients in both directions, ensuring comprehensive coverage for the data lines it is connected to.

Key features of the SRDA05-4R2 include:

• Low capacitance of 5pF per line, ideal for high-speed data applications.
• ESD protection to IEC61000-4-2 Level 4 (±15kV air, ±8kV contact discharge).
• Low clamping voltage to protect sensitive components from voltage spikes.
• Low leakage current to preserve the energy efficiency of the overall system.
• SO-8 package for a compact footprint on the PCB.
• RoHS compliant and lead-free, ensuring environmental safety and regulatory compliance.

By integrating the SRDA05-4R2 into your design, you can enhance the durability and reliability of your electronic products, ensuring they withstand the rigors of everyday use and unexpected electrical events. ON Semiconductor's commitment to quality and performance makes the SRDA05-4R2 a trusted choice for your circuit protection needs.
