MKP9V160RL

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.

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

Applications

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

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.

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.

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.

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.

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.
