MKP3V240G

DIACs, SIDACs Overview

The MKP3V240G is a bidirectional SIDAC thyristor manufactured by Littelfuse Inc. designed for breakover switching applications in AC power line circuits. It features an axial lead package and operates within a breakover voltage range of 220 to 250 volts. The device supports a peak current of 1 ampere, providing reliable triggering for sensitive components. This component is classified as obsolete and is no longer in active manufacturing.

DIACs, SIDACs Feature Summary

• Bidirectional switching capability for direct AC power line interface
• Reliable trigger device for breakover switching applications
• Axial lead construction for through-hole mounting

DIACs, SIDACs Applications

• Triggering devices for SCR or TRIAC gates
• Overvoltage protection circuits
• AC power line interface circuits

DIACs, SIDACs Procurement Notes

This component is officially listed as obsolete and is no longer manufactured by Littelfuse Inc. Verification of availability should focus on surplus stock or secondary market sources rather than direct manufacturer distribution. Buyers must confirm the authenticity of existing inventory and check for valid substitutes such as the K2400GRP if new production units are required.

DIACs, SIDACs Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. The fixed breakover voltage range of 220-250V limits its use to specific AC line voltages. Alternative selection should prioritize available SIDACs with similar voltage ratings and axial packaging to ensure compatibility with existing circuit layouts and performance requirements.

DIACs, SIDACs Part Context

The MKP3V240G belongs to the SIDAC family of thyristors, which are specifically engineered for high-voltage triggering and protection. These devices operate symmetrically in both directions, making them suitable for AC applications. The product line emphasizes robust switching characteristics for industrial and consumer electronics protection schemes.

DIACs, SIDACs Replacement Considerations

Public confirmed substitute part numbers include K2400GRP from Littelfuse Inc. Users should verify that the substitute matches the original's axial lead form factor and voltage specifications before integration.
