L0107NTRP4

Triacs Overview

The L0107NTRP4 is a bidirectional triac from the Littelfuse L01 EV Series, designed as a sensitive gate device for direct microprocessor interface. It features an RMS on-state current of 1 A and offers rated repetitive off-state voltages (VDRM) ranging from 400 V to 800 V. The device exhibits a maximum on-state voltage of 1.6 V and a leakage current of 5 uA at VDRM. Gate triggering parameters include a maximum DC gate trigger voltage of 1.3 V and currents between 5 mA and 7 mA. It operates within a temperature range of -40 C to +125 C and is housed in a surface-mount SOT-223-4 package.

Triacs Feature Summary

• Sensitive gate architecture enabling direct connection to low-power logic drivers without additional buffering components.
• Glass-passivated junctions engineered to ensure long-term parametric stability and reliability under thermal stress.
• Compact surface-mount form factor optimized for automated assembly and high-density PCB layouts.

Triacs Applications

• Solid-state switching circuits requiring microprocessor control.
• AC phase control applications such as lighting dimmers.
• Temperature modulation controls for heating elements.

Triacs Procurement Notes

Verify the specific voltage rating suffix required for the design, as the L01 series spans multiple blocking voltages. Confirm the SOT-223-4 package compatibility with the target footprint. Ensure the sensitive gate characteristics align with the driving circuit's output capabilities. Check RoHS compliance status against regional regulatory requirements before finalizing procurement.

Triacs Selection Notes

Select this component when a 1 A RMS current capacity is sufficient for the load. Choose the L0107NTRP4 variant specifically for surface-mount assembly needs. Compare the 400 V to 800 V voltage options based on the peak line voltage and transient spikes present in the application environment. Ensure the driving source can supply the specified 5 mA to 7 mA gate trigger current reliably.

Triacs Part Context

This part belongs to the L01 EV Series, a family of 1 Amp sensitive triacs manufactured by Littelfuse. The series provides both through-hole and surface-mount options to accommodate diverse manufacturing processes. These devices are positioned as economical solid-state switches for general-purpose AC control tasks where low drive power is essential.

Triacs Replacement Considerations

Direct substitutes within the same series include other L0107 variants with different voltage ratings or packaging styles, such as L0107DTRP or L0107MEAP. Verify that any replacement maintains the 1 A RMS current rating and compatible gate sensitivity specifications to ensure functional equivalence in the existing circuit design.
