Q601E3RP

Triacs Overview

The Littelfuse Q601E3RP is a TECCOR brand triac belonging to the Lx01Ex series, designed for general-purpose AC power control applications. It features a TO-92 through-hole package and supports an RMS on-state current (It RMS) of 1 A with a rated repetitive peak off-state voltage (VDRM) of 600 V. The device exhibits a maximum holding current (Ih) of 5 mA and requires a gate trigger current (Igt) of 3 mA at a gate trigger voltage (Vgt) of 2 V. It operates within a junction temperature range of -40°C to +125°C, ensuring reliable performance in standard industrial and consumer environments.

Triacs Feature Summary

• Sensitive gate architecture enabling direct interfacing with microprocessor drivers and logic circuits
• Robust thermal management capabilities supporting high operating temperatures up to 125°C
• Standardized TO-92 through-hole packaging facilitating easy integration into printed circuit boards

Triacs Applications

• Solid-state relays and motor speed controls
• Lighting dimmers and lamp brightness regulators
• General-purpose AC load switching in household appliances

Triacs Procurement Notes

Verify the specific suffix RP against official Littelfuse documentation to confirm reel packaging specifications and ensure compatibility with automated assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Triacs Selection Notes

Select this component when a low-current, sensitive-gate triac is required for controlling AC loads up to 1 A. Ensure the gate drive circuit can supply at least 3 mA at 2 V to guarantee reliable triggering. Verify that the PCB layout accommodates the TO-92 package dimensions and provides adequate thermal relief for the expected operating conditions.

Triacs Part Context

This part belongs to the TECCOR Lx01Ex family of sensitive gate triacs, widely used in low-power AC switching applications. The Q601E3RP variant specifically denotes the 600V, 1A rating within this series, offering a cost-effective solution for basic power control tasks where high sensitivity and compact packaging are prioritized over high current handling.

Triacs Replacement Considerations

Direct replacements include other 600V, 1A sensitive gate triacs in TO-92 packages from manufacturers such as STMicroelectronics or Vishay, provided they meet the same electrical parameters for VDRM, It RMS, and gate sensitivity.
