MKP9V160RLG

Overview

The MKP9V160RLG is a bidirectional high-voltage trigger device manufactured by onsemi, designed for direct AC power line interface. It operates in the DO-41 axial lead package and features glass passivation for reliable operation. The device switches from a blocking state to a low voltage on-state upon reaching its breakover voltage, maintaining conduction until current drops below the holding threshold. Key electrical parameters include a peak repetitive off-state voltage of 160 V, a typical breakover voltage range of 150 V to 170 V, and an RMS on-state current capability of 0.9 A at 80°C. The component supports a junction temperature range of -40°C to +125°C.

Feature Summary

• Bidirectional triggering mechanism suitable for direct AC power line interfacing
• Glass passivation ensures reliable operation under high-stress conditions
• Axial lead plastic package provides high pulse current capability

Applications

• High pressure sodium vapor lighting systems
• Strobes and flasher circuits
• Ignitor applications
• Triggering gates of SCRs and Triacs

Procurement Notes

Verify the specific ordering suffix RLG to confirm the tape and reel packaging configuration with a quantity of 5000 units. Ensure compliance with RoHS standards as indicated by the G suffix. Confirm that the component meets UL registration requirements for file number E116110 before final integration into certified designs.

Selection Notes

Select this component when a bidirectional trigger capable of handling 160 V peak repetitive off-state voltage is required. Consider the 0.9 A RMS on-state current limit and the 150 V to 170 V breakover voltage range for circuit design. Evaluate thermal management needs based on the 40 °C/W junction-to-lead thermal resistance characteristic.

Part Context

This part belongs to the SIDAC family of high-voltage bidirectional triggers produced by onsemi. These devices are engineered for robust performance in AC mains applications, offering a cost-effective solution for overvoltage protection and gate triggering functions compared to more complex semiconductor alternatives.

Replacement Considerations

Consult official cross-reference documentation for verified substitutes. Generic equivalents may differ in breakover voltage tolerances or thermal characteristics.
