Q6012LH2

Triacs Overview

The Q6012LH2 is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 12 A. The device operates within a junction temperature range of -40°C to +110°C. Key electrical parameters include a maximum holding current of 6 mA, a gate trigger voltage of 50 V, and a gate trigger current of 1.5 A. The on-state voltage drop is specified at 1.6 V, with a non-repetitive peak on-state current capability of 120 A. The component utilizes a TO-220-2 package for through-hole mounting.

Triacs Feature Summary

• High thermal stability supporting operation up to +110°C
• Robust surge handling with 120 A non-repetitive peak current
• Sensitive gate triggering characteristics for efficient drive circuits

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides authentic Littelfuse components with traceable documentation to prevent counterfeit risks in power control designs.

Triacs Selection Notes

Select this component when a 600 V rating and 12 A continuous current capacity are required for AC switching. Consider the TO-220-2 package for adequate heat dissipation without additional heatsinking in moderate duty cycles. Verify gate sensitivity requirements align with the 1.5 A trigger current specification.

Triacs Part Context

This part belongs to the Teccor family of thyristors from Littelfuse, widely recognized in industrial and consumer power electronics. The Q-series designations typically denote standard triac configurations optimized for general-purpose AC regulation tasks requiring reliable latching and commutation.

Triacs Replacement Considerations

Consult Littelfuse cross-reference guides for verified equivalents. Potential substitutes may include other 600 V, 12 A triacs in TO-220 packages from manufacturers like STMicroelectronics or Vishay, provided pinouts and electrical ratings match exactly.
