The SMDA15CN-5 is a transient voltage suppressor (TVS) diode array manufactured by Semtech Corporation. This device is designed to protect sensitive electronic equipment from voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning surges. It is commonly used in data lines, I/O ports, and other interfaces.

Applications

• Protection of data lines (e.g., USB, Ethernet, RS-232)
• Protection of I/O ports
• Protection of microcontrollers and other sensitive components
• Industrial control systems
• Telecommunications equipment

Features

• Low Clamping Voltage: Limits the voltage across the protected device during a transient event.
• Fast Response Time: Quickly responds to transient events, minimizing the risk of damage.
• Low Capacitance: Minimizes signal degradation on high-speed data lines.
• ESD Protection: Provides protection against electrostatic discharge (ESD) events.
• Robust Surge Protection: Withstands high surge currents and voltages.

Benefits

• Enhanced System Reliability: Protects sensitive electronic components from damage due to transient events.
• Reduced Downtime: Minimizes equipment failures caused by ESD and surge events.
• Improved Product Lifespan: Extends the life of electronic products by protecting them from electrical stress.
• Compliance with Industry Standards: Meets or exceeds industry standards for ESD and surge protection.
• Easy to Implement: Simple and compact design for easy integration into existing circuits.

Technical Specifications

The SMDA15CN-5 features a standoff voltage of 15V and a clamping voltage of approximately 22V at a specified surge current. It provides protection against ESD events up to ±30kV (air discharge) and ±30kV (contact discharge). The device has a low capacitance of typically 3 pF. It is available in an SO-8 package.
