MKP1V120RL

Overview

The MKP1V120RLG is a high-voltage bidirectional trigger device (SIDAC) from the MKP1V120 Series, manufactured by onsemi. It features an axial lead DO-41 package and is designed for direct interface with AC power lines. The device switches from a blocking state to a low voltage on-state upon reaching its breakover voltage in either direction. Key electrical parameters include a repetitive peak off-state voltage of 120 V, a typical breakover voltage range of 110 V to 130 V, and an RMS on-state current rating of 0.9 A at 80°C. It supports a peak non-repetitive surge current of 4.0 A and operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• Bidirectional triggering capability for direct AC line interface
• Glass passivation for reliable operation
• Axial lead package providing high pulse current capability

Applications

• High pressure sodium vapor lighting
• Strobes and flashers
• Ignitors
• Triggering gates of SCRs and Triacs

Procurement Notes

Verify the specific ordering suffix RLG to confirm tape and reel packaging containing 5000 units per reel. Confirm RoHS compliance status as the base package is inherently lead-free. Ensure the component matches the MKP1V120 series specifications rather than other variants like MKP1V130 or MKP1V160 which have different breakover voltages.

Selection Notes

Select this component when a bidirectional trigger device is required for AC line applications. The 120 V nominal breakover voltage suits circuits requiring activation within the 110 V to 130 V range. Consider the 0.9 A RMS current rating and thermal characteristics for heat dissipation requirements. Verify that the DO-41 axial package fits the board layout constraints.

Part Context

The MKP1V120RLG belongs to the MKP1V120 Series of SIDACs, which includes variants with different breakover voltages such as MKP1V130, MKP1V160, and MKP1V240. These devices share similar physical packages and general characteristics but differ in their specific voltage thresholds. The series is designed for robust performance in lighting and ignition applications.

Replacement Considerations

Direct substitutes within the same series include MKP1V130RLG, MKP1V160RLG, and MKP1V240RLG, provided the circuit can accommodate their respective breakover voltages. Other manufacturers' SIDACs with matching voltage ratings and current capabilities may also be considered if pin compatibility and thermal performance are verified.
