• Designed specifically for ESD surge protection applications
• Utilizes a three-channel configuration for multi-line protection

Applications

• General purpose ESD protection
• Protection of IC I/O terminals

Procurement Notes

Verify the current lifecycle status as sources indicate this part may be obsolete. Confirm availability through authorized distributors or secondary markets if standard supply channels do not list active stock. Ensure the 3-SIP package and 25V rating match the specific design requirements before procurement.

Selection Notes

Select this component when designing circuits requiring robust ESD protection for multiple signal lines. The 3-channel architecture suits interfaces with three distinct data or control lines. Verify that the 25V rated voltage aligns with the operating voltage of the protected integrated circuit to ensure effective clamping without interference.

Part Context

This component belongs to the VFR3V series manufactured by Murata Electronics. The series is engineered to protect sensitive electronic components from electrostatic discharge events. It serves as a specialized filter solution for maintaining signal integrity while mitigating high-voltage transients in low-voltage digital interfaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the potentially obsolete status, verify compatibility with alternative Murata ESD protection devices or generic 3-channel SIP filters that meet the 25V and 130pF specifications.
