MKP1V120RLG

Overview

The MKP1V120RLG is a SIDAC diode manufactured by Littelfuse Inc., designed for robust overvoltage protection in high-exposure environments. It features a rated repetitive off-state voltage (VDRM) of 90 V and supports a non-repetitive on-state current of 4 A. The device operates within an ignition voltage range of 110 to 130 V and handles a rated RMS current of 0.9 A. Packaged in a 2-pin DO-41 axial configuration, it aids end-products in meeting IEC 62368-1 overvoltage requirements.

Feature Summary

• Engineered to provide robust overvoltage protection in high-exposure environments
• Helps end-products meet IEC 62368-1 overvoltage requirements for equipment

Applications

• IEC 62368-1 compliant equipment protection
• High-exposure environment circuit safeguarding
• Overvoltage protection systems

Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm availability through authorized distributors or secondary markets, as standard supply chains may not stock this specific part number. Ensure the ordering suffix matches the required tape-and-reel packaging format. Cross-reference datasheets for any specification updates prior to integration into new designs.

Selection Notes

Select this component when designing circuits requiring reliable overvoltage protection that complies with IEC 62368-1 standards. Consider its 90 V rated voltage and 110-130 V ignition range for appropriate triggering thresholds. Evaluate the 4 A non-repetitive current capacity against potential surge events. Verify compatibility with the DO-41 axial package constraints for the target application layout.

Part Context

This part belongs to the MKP1V series of SIDACs from Littelfuse. These devices are categorized under discrete semiconductor products, specifically Diac/Sidac Thyristors. The series is engineered for circuit protection applications, offering axial lead configurations suitable for through-hole mounting in various electronic assemblies requiring overvoltage suppression.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle status, direct replacements should be identified by matching electrical parameters such as 90 V VDRM, 110-130 V ignition voltage, and DO-41 package type from other manufacturers.
