MKP1V240RL

Overview

The MKP1V240RLG is a bidirectional SIDAC trigger from the MKP1V120 Series, designed for direct AC power line interface. It switches from a blocking state to a low voltage on-state upon reaching breakover voltage, conducting like a Triac until current drops below holding levels. Key electrical parameters include a peak repetitive off-state voltage (VDRM/VRRM) of 180 V and a typical breakover voltage (VBO) ranging from 220 V to 250 V at IBO = 35 µA. The device supports an RMS on-state current of 0.9 A and a peak non-repetitive surge current of 4.0 A. It operates within a junction temperature range of -40°C to +125°C and utilizes a DO-41 axial lead package.

Feature Summary

• Bidirectional triggering capability for direct AC line interface
• Glass passivation for reliable operation
• High pulse current capability with low cost
• UL Registered component

Applications

• High Pressure Sodium Vapor Lighting
• Strobes and Flashers
• Ignitors
• Triggering Gates of SCRs and Triacs

Procurement Notes

Verify the complete ordering suffix 'RLG' to confirm tape and reel packaging containing 5000 units per reel. Confirm Pb-Free status and DO-41 axial lead package type. Ensure compatibility with required breakover voltage specifications for the specific circuit application before procurement.

Selection Notes

Select this component when a bidirectional trigger with a nominal 240 V breakover voltage is required. Verify that the 0.9 A RMS current rating and 180 V repetitive off-state voltage meet the circuit's maximum operating conditions. Consider thermal derating curves for ambient temperatures exceeding 25°C to ensure reliability under continuous load.

Part Context

This part belongs to the MKP1V120 Series, which includes variants with different breakover voltages such as MKP1V120 (120 V), MKP1V130 (130 V), and MKP1V160 (160 V). All series members share similar physical dimensions and electrical characteristics except for the specific breakover voltage thresholds defined by the model number.

Replacement Considerations

Direct substitutes within the same series include MKP1V120RLG, MKP1V130RLG, and MKP1V160RLG, provided their lower breakover voltages are acceptable for the application. Other manufacturers' SIDAC devices with equivalent 180 V VDRM and ~240 V VBO ratings may be considered if pinout and package dimensions match.
