Triacs datasheet and documents for Q6015LTH

Q6015LTH

Triacs Overview

The Littelfuse Q6015LTH is a Quadrac device, which integrates a triac and an internal diac trigger within a single package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (ITRMS) of 15 A. The device has a non-repetitive peak on-state current capability of up to 200 A at 60 Hz. Key electrical parameters include a maximum holding current (Ih) of 70 mA, a gate trigger current (Igt) of 1.5 A, and an on-state voltage (VTM) of 1.6 V. The turn-on breakover voltage (VBO) ranges from 33 V to 43 V. It operates within a junction temperature range of -40°C to +125°C and is housed in a TO-220-2 through-hole package.

Triacs Feature Summary

Integrates a diac trigger inside the same package as the triac to simplify circuit design.
Eliminates the need for an external snubber network due to alternistor technology.
Provides high surge current capability up to 200 A for robust performance.
Features electrically isolated packaging with glass-passivated junctions for reliability.

Triacs Applications

AC switching and phase control applications
Speed controls for motors
Temperature modulation controls
Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type is TO-220-2 and ensure the part number suffix matches the exact variant required. Inspect leads for damage and verify storage conditions to prevent moisture sensitivity issues prior to soldering.

Triacs Selection Notes

Select this component when a bidirectional AC switch with integrated triggering is needed to reduce assembly steps. Ensure the application voltage does not exceed 600 V and the continuous current load remains within 15 A. Consider the thermal management requirements for the TO-220 package given the 125°C maximum operating temperature limit.

Triacs Part Context

The Q6015LTH belongs to the Teccor QxxxxLTx series of Quadrac devices manufactured by Littelfuse. This series combines triacs with internal diac triggers to offer a compact solution for AC power control. The specific LTH suffix denotes the alternistor version that removes the requirement for external snubber circuits, distinguishing it from standard gated triacs.
