MKP1V160RLG

Overview

The MKP1V160RLG is a bidirectional SIDAC trigger device from the MKP1V120 series, manufactured by onsemi. It features a DO-41 axial lead package and operates within a junction temperature range of -40°C to +125°C. The component has a peak repetitive off-state voltage (VDRM) of 180 V and an RMS on-state current rating of 0.9 A at 80°C. Typical breakover voltage ranges from 150 V to 170 V with a maximum of 200 V. Peak on-state voltage is typically 1.3 V at 1 A peak current. Dynamic holding current is limited to 100 mA, and the critical rate-of-rise of on-state current (di/dt) is typically 120 A/µs.

Feature Summary

• Bidirectional switching capability for direct AC power line interface
• Glass passivation for reliable operation in high-voltage environments
• Axial lead package design supporting 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 confirms 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 datasheet revision 12 specifications for electrical characteristics and thermal resistance values before integration into production designs.

Selection Notes

Select this component when a bidirectional trigger device is required for AC line interfacing with a breakover voltage near 160 V. The 0.9 A RMS current rating suits moderate power applications like lighting ignitors. Verify that the DO-41 axial package fits the PCB layout constraints and that the 180 V blocking voltage meets the circuit's peak repetitive off-state requirements without exceeding limits.

Part Context

This part belongs to the MKP1V120 Series of Sidac High Voltage Bidirectional Triggers. It shares the same package outline and general thermal characteristics as siblings like the MKP1V120RLG and MKP1V130RLG, differing primarily in the breakover voltage threshold. The 'RLG' suffix specifically denotes the reel packaging format for automated assembly.

Replacement Considerations

Compatible substitutes include other MKP1V160 variants such as MKP1V160G (bulk packaging). Cross-series replacements must match the 180 V VDRM and 0.9 A IT(RMS) ratings. Verify di/dt capabilities and holding current specifications align with the original circuit design requirements.
