Q6015LT58

Triacs Overview

The Littelfuse Q6015LT58 is a bidirectional triac from the Teccor QxxxxLTx series, designed for AC switching and phase control. It features an integrated diac trigger within a single TO-220AB package, eliminating the need for external discrete components. The device has a rated on-state RMS current of 15 A and a repetitive peak off-state voltage of 600 V. Key electrical parameters include a maximum gate trigger current of 50 mA, a peak on-state voltage of 1.6 V, and a surge current rating of 200 A. It operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Integrated Diac Trigger: Combines a triac and diac in one package to simplify circuit design and reduce assembly time.

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix LT58 against official Littelfuse documentation to confirm pinout and isolation specifications. Ensure the ordering part number matches the required JEDEC TO-220AB package variant. Confirm RoHS compliance status through the manufacturer's latest datasheet or product change notifications before procurement.

Triacs Selection Notes

Select this component for applications requiring noise immunity and simplified gate drive circuits. The integrated diac feature reduces bill-of-materials complexity compared to separate triac and diac assemblies. Verify that the 15 A RMS current and 600 V blocking voltage meet the load requirements of the specific AC switching application.

Triacs Part Context

This device belongs to the Teccor QxxxxLTx Quadrac series by Littelfuse. These devices are specifically engineered as bidirectional AC switches with internal triggering mechanisms. The series offers current capacities ranging from 4 A to 15 A and voltage ratings up to 600 V, providing electrically isolated mounting options in TO-220 packages.

Triacs Replacement Considerations

Direct replacements must be verified against the official Littelfuse substitution guide. Generic triacs without integrated diacs require additional circuit redesign. Ensure any substitute maintains the same TO-220AB footprint and thermal characteristics.
