ERZ-VGED431

Overview

The Panasonic ERZ-VGED431 is a ZNR surge absorber from the V series, designed for through-hole mounting. It features a radial leaded disk package with a 7.5 mm lead spacing and 0.8 mm lead diameter. The component has a varistor voltage of 430 V (range 387–473 V), rated for 275 VAC and 350 VDC. It withstands a maximum clamping voltage of 710 V and handles peak surge currents up to 6000 A (8/20 µs). Energy ratings include 110 J at 2 ms and average pulse power of 0.60 W. Capacitance is 450 pF max, operating between -40 °C and 85 °C.

Feature Summary

• Provides transient and surge protection via non-linear resistance characteristics
• Utilizes ZNR technology for reliable voltage clamping during overvoltage events
• Designed for robust performance in high-energy impulse environments

Applications

• Protection of electronic circuits against voltage spikes
• Surge absorption in AC/DC power supply inputs
• Transient suppression in industrial control systems

Procurement Notes

Verify the specific suffix 'GED' against official Panasonic documentation to confirm exact physical dimensions and packaging type, as variations exist within the V series. Confirm RoHS compliance status and check for any End-of-Life notices or production discontinuation notifications prior to finalizing procurement plans.

Selection Notes

Select this component when a 430 V varistor voltage is required for 275 VAC applications. Ensure the PCB layout accommodates the 7.5 mm lead spacing and radial leads. Verify that the 110 J energy rating and 6000 A peak current capability meet the expected surge environment requirements of the target circuit design.

Part Context

This part belongs to the Panasonic ERZ-V series of ZNR surge absorbers. These components are metal oxide varistors specifically engineered for transient voltage suppression. The V series offers various sizes and ratings to suit different power handling needs, with the GED variant representing a specific form factor within this lineup.

Replacement Considerations

Check Panasonic's official substitution guide for equivalent parts with matching voltage ratings and energy capabilities. Ensure any substitute maintains the same lead spacing and package dimensions for direct replacement compatibility.
