The CMPZDA22V TR PBFREE is a Transient Voltage Suppressor (TVS) diode array manufactured by Central Semiconductor Corp. This device is designed to protect sensitive electronic components from voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning surges. The 'PBFREE' designation indicates that the device is lead-free, complying with RoHS environmental standards.

Applications

• ESD Protection: Protects I/O ports, data lines, and power lines from damage due to electrostatic discharge.
• EFT Protection: Safeguards circuits from electrical fast transients generated by switching or inductive loads.
• Surge Protection: Provides protection against voltage surges caused by lightning or other transient events.
• Microcontroller Protection: Protects microcontroller I/O pins from overvoltage conditions.
• Data Line Protection: Protects data lines in communication interfaces such as USB, Ethernet, and RS-485.

Features

• Low Clamping Voltage: Limits the voltage across protected components to a safe level during transient events.
• Fast Response Time: Quickly responds to transient events, ensuring effective protection.
• Low Capacitance: Minimizes signal distortion in high-speed data lines.
