The USB50405C is a Transient Voltage Suppressor (TVS) diode array manufactured by Microsemi Corporation. This device is designed to protect sensitive electronic components from voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning surges. It provides robust overvoltage protection for data lines and power lines.

Applications:

• USB ports
• Ethernet ports
• HDMI ports
• RS-232/RS-485 interfaces
• Power supply lines

Features:

• Low clamping voltage
• Fast response time
• Low capacitance
• ESD protection per IEC 61000-4-2
• EFT protection per IEC 61000-4-4

Benefits:

• Protection against voltage transients, increasing system reliability
• Minimized signal distortion due to low capacitance
• Rapid response to transient events
• Compliance with industry standards for ESD and EFT immunity
• Prevention of damage to sensitive electronic components

Additional Details:

The USB50405C features a standoff voltage of 5V and a clamping voltage typically under 10V during a transient event. It offers bidirectional protection. Its low capacitance makes it suitable for high-speed data lines, preventing signal degradation. The device is available in a small surface mount package for easy integration into circuit boards. The device conforms to industry standards, ensuring robust protection against ESD and EFT threats. This device protects the circuit from damage or failure due to voltage spikes.
