L0109MTRP4

Triacs Overview

The Littelfuse L0109MTRP4 is a bidirectional triac from the L01 EV Series, designed for sensitive gate triggering applications. It features an RMS on-state current of 1 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device exhibits a maximum holding current of 10 mA and a typical on-state voltage of 1.6 V. Gate trigger parameters include a maximum voltage of 1.3 V and current of 10 mA. It operates within a temperature range of -40°C to +125°C and is housed in a TO-92 through-hole package.

Triacs Feature Summary

• Sensitive gate design enabling reliable triggering with low gate drive requirements
• High thermal stability supporting operation up to 125°C junction temperature
• Robust off-state blocking capability suitable for general AC switching loads

Triacs Applications

• Lighting control circuits requiring sensitive gate triacs
• Solid-state relay input stages
• AC motor speed control applications

Triacs Procurement Notes

Verify the specific suffix 'MTRP4' against official Littelfuse documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the required sensitivity class and package type for your assembly process. Cross-reference with authorized distributors to confirm availability and authenticity before procurement.

Triacs Selection Notes

Select this component when a 1 A RMS current rating and 600 V blocking voltage are sufficient for the load. The sensitive gate characteristic (Igt max 10 mA) allows compatibility with low-power logic outputs. Verify that the TO-92 package fits the PCB layout constraints and that the thermal management supports the expected power dissipation at the operating current.

Triacs Part Context

This part belongs to the Littelfuse L01 series of small-signal triacs. The series is characterized by its compact TO-92 form factor and suitability for low-power AC switching tasks. The L0109 variant specifically denotes the 600 V blocking voltage rating within this family.

Triacs Replacement Considerations

Check for direct equivalents such as the L0109ME or other L01 series parts with identical electrical ratings and pinout configurations. Ensure any substitute maintains the sensitive gate requirement and TO-92 package style.
