MKP9V160RL

DIACs, SIDACs Overview

The MKP9V160RL is a bidirectional SIDAC trigger device manufactured by onsemi, designed for direct interface with AC power lines. It operates in the DO-41 axial lead package and switches from a high-resistance blocking state to a low-voltage conducting state upon reaching its breakover voltage. The component supports a peak repetitive off-state voltage of up to 160 V and an RMS on-state current of 0.9 A. Key electrical parameters include a typical breakover voltage of 150 V, a maximum holding current of 100 mA, and a critical rate-of-rise of on-state current (di/dt) of 120 A/µs.

DIACs, SIDACs Feature Summary

• Bidirectional switching capability for direct AC line interfacing
• Glass passivation ensures reliable operation under stress
• Axial lead package provides high pulse current handling at low cost

DIACs, SIDACs Applications

• High pressure sodium vapor lighting circuits
• Strobe and flasher ignition systems
• Triggering gates of SCRs and Triacs
• High voltage regulator protection

DIACs, SIDACs Procurement Notes

Verify that the specific suffix RL indicates tape and reel packaging containing 5000 units per reel. Confirm the presence of the Pb-free marking if environmental compliance is required. Ensure the ordering part number matches the exact voltage rating and package style needed for the design.

DIACs, SIDACs Selection Notes

Select this component when a bidirectional trigger is required for AC mains applications. Verify that the circuit can handle the 0.9 A RMS current limit and that the operating junction temperature remains within the -40°C to +125°C range. Ensure the load current does not exceed the specified di/dt limits during turn-on.

DIACs, SIDACs Part Context

This device belongs to the SIDAC family of high-voltage bidirectional triggers produced by onsemi. These components are distinct from standard thyristors as they function primarily as voltage-triggered switches for protection and timing applications rather than latching relays.

DIACs, SIDACs Replacement Considerations

Check datasheets for other SIDAC devices with similar breakover voltages around 150-170 V and comparable current ratings. Ensure any substitute maintains the DO-41 axial package and bidirectional characteristics for direct AC replacement.

DIACs, SIDACs FAQ

What is the typical breakover voltage for the MKP9V160RL?

The typical breakover voltage is 150 V, with a guaranteed range between 150 V and 170 V.

How does the device maintain conduction after triggering?

Conduction continues like a Triac until the main terminal current drops below the holding current threshold of 100 mA.

What is the maximum allowable junction temperature?

The operating junction temperature range extends up to +125°C.
