MKP1V160

Overview

The MKP1V160 is a bidirectional high-voltage trigger device (SIDAC) from the MKP1V120 series, manufactured by onsemi. It features an axial lead DO-41 package and operates within a junction temperature range of -40°C to +125°C. The component has a peak repetitive off-state voltage rating of 180 V and an RMS on-state current capacity of 0.9 A at 80°C. Electrical characteristics include a breakover voltage range of 150 V to 170 V at a breakover current of 35 µA, with a maximum dynamic holding current of 100 mA. Peak non-repetitive surge current capability is rated at 4.0 A for a single 60 Hz cycle.

Feature Summary

• Bidirectional switching behavior designed for direct AC power line interface
• Glass passivation ensures reliable operation under high-stress conditions
• Plastic axial lead package provides high pulse current capability

Applications

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

Procurement Notes

Verify the specific ordering suffix when purchasing. Suffixes such as 'G' indicate bulk packaging, while 'RLG' indicates tape and reel quantities. Confirm RoHS compliance status and package type directly with the supplier or manufacturer documentation prior to procurement to ensure alignment with assembly requirements.

Selection Notes

Select the MKP1V160 based on its 150 V to 170 V breakover voltage window for applications requiring this specific triggering threshold. Ensure the circuit design accommodates the 0.9 A RMS current limit and the 4.0 A peak surge capability. Consider thermal derating curves if ambient temperatures exceed standard operating ranges or if conduction angles vary significantly from the standard sine wave test conditions.

Part Context

This component belongs to the MKP1V120 Series, which includes variants with different breakover voltages such as the MKP1V120, MKP1V130, and MKP1V240. All devices in this series share the same DO-41 axial lead package and general electrical structure, differing primarily in their specified breakdown voltage thresholds for various high-voltage triggering applications.

Replacement Considerations

Compatible substitutes within the same family include MKP1V120, MKP1V130, and MKP1V240. Verify that the alternative part number's breakover voltage aligns with the circuit design requirements before substitution.
