Q4010N5RP

Triacs Overview

The Littelfuse Q4010N5RP is a bidirectional triac designed for AC power control applications. It features an RMS on-state current of 10 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 50 mA to 75 mA. Non-repetitive peak on-state currents are specified at 100 A and 120 A under different conditions, with an on-state voltage of 1.6 V and a leakage current of 10 µA.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• Surface-mount construction in an SMTO-263-2 package for automated assembly
• High thermal stability supporting operation up to 125°C

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific Littelfuse datasheet revision and RoHS compliance status prior to finalizing design integration. Confirm that the SMTO-263-2 footprint matches the target PCB layout requirements. Ensure that the 400 V voltage rating provides adequate margin for the intended AC line voltage application.

Triacs Selection Notes

Select this component when a 10 A RMS current capacity and 400 V blocking voltage are required in a surface-mount form factor. Consider the 50 mA holding current specification to ensure reliable latching in the load circuit. Evaluate the gate trigger characteristics against the available drive signal amplitude and source impedance.

Triacs Part Context

This part belongs to the Littelfuse Qxx10xx series of thyristors. It serves as a solid-state alternative to mechanical relays in AC power switching roles. The device integrates three terminals: Main Terminal 1, Main Terminal 2, and Gate, facilitating direct interface with microcontroller-driven gate drivers.

Triacs Replacement Considerations

The Q4012NH5RP is a related device offering 12 A RMS current and lower gate trigger voltage. Verify pinout compatibility and thermal dissipation requirements before substituting between these specific part numbers.
