Q8010L4

Triacs Overview

The Littelfuse Q8010L4 is a bidirectional triac from the Qxx10xx series, designed for AC switching and phase control applications. It features an RMS on-state current of 10 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a 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 35 mA, a gate trigger voltage of 2.5 V, and an on-state voltage of 1.6 V. Non-repetitive peak currents are specified at 100 A and 120 A, with a leakage current of 10 uA under VDRM conditions.

Triacs Feature Summary

• Bidirectional AC switching capability for phase control
• Glass-passivated junctions for parameter stability
• Surface-mount construction for automated assembly

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix 'L4' against official Littelfuse documentation to confirm pinout and thermal characteristics. Ensure compatibility with SMTO-263-2 footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing component selection.

Triacs Selection Notes

Select this component for designs requiring 800 V blocking voltage and 10 A continuous current handling in a compact SMD form factor. Evaluate thermal management requirements given the 125°C maximum operating temperature limit. Compare gate trigger specifications against available drive circuitry to ensure reliable turn-on across the full operating temperature range.

Triacs Part Context

This part belongs to the Qxx10xx series of Triacs manufactured by Littelfuse under the Teccor brand. These devices are engineered for robust performance in general-purpose AC power control circuits. The series emphasizes reliability through glass-passivated junction technology and standardized packaging options suitable for high-volume manufacturing processes.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or thermal resistance. Verify that any substitute maintains the same SMTO-263-2 package dimensions and electrical ratings to ensure mechanical and functional compatibility.
