Microchip Technology's SMDA03C-4E3/TR7 TVS Diode Array

The SMDA03C-4E3/TR7 is a robust transient voltage suppressor (TVS) diode array from Microchip Technology, designed to provide reliable protection for sensitive electronic components against voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. This protective device is an essential component in safeguarding modern electronics found in telecommunications, computer interfaces, and other data communication systems.

This TVS diode array features four channels of ESD protection, with each channel consisting of a pair of diodes that steer ESD pulses to either the positive supply line or ground. The SMDA03C-4E3/TR7 is capable of dissipating ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard, ensuring devices remain safe from the most common electrical threats encountered in daily operation.

With its low clamping voltage and low leakage current, the SMDA03C-4E3/TR7 is optimized to protect sensitive circuitry without impacting the performance of the protected device. The array's bidirectional configuration means that it can respond to transient events arriving from either direction, making it highly versatile for different circuit designs.

Manufactured in a compact SO-8 package, the SMDA03C-4E3/TR7 is designed for surface-mount technology (SMT), allowing for efficient assembly and saving valuable board space in dense electronic systems. The component's lead-free design adheres to current environmental standards, reducing the ecological impact and ensuring compliance with global regulations.

Key features of the SMDA03C-4E3/TR7 include:

• ESD protection to IEC 61000-4-2 (Level 4)
• Low clamping voltage
• Low leakage current
• Four lines of protection
• SO-8 package for compact SMT designs
• RoHS compliant and lead-free

The SMDA03C-4E3/TR7 is a testament to Microchip Technology's commitment to providing advanced protection solutions for electronic systems. By incorporating this TVS diode array into their designs, engineers can significantly enhance the durability and reliability of their products, ensuring long-term performance and customer satisfaction.
