Q8012LH2TP

Triacs Overview

The Q8012LH2TP is a Triac manufactured by Littelfuse Inc., designed for AC power control applications. It features an 800V repetitive peak off-state voltage and a 12A RMS on-state current rating. The device utilizes a gate trigger current specification of 10-10-10 mA, indicating sensitivity across different temperature ranges. It is housed in an isolated TO-220AB plastic package with three pins, suitable for flange mounting. The component operates within a junction temperature range of -40°C to 125°C. Key electrical characteristics include a maximum DC gate trigger current of 10 mA, a maximum DC gate trigger voltage of 1.3 V, and a holding current of 15 mA. It exhibits a critical rate of rise of off-state voltage of 150 V/us and a critical rate of rise of on-state voltage of 2 V/us.

Triacs Feature Summary

• High-voltage blocking capability for robust AC switching
• Sensitive gate drive requirements for efficient control circuitry
• Thermal resilience for high-temperature industrial environments

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'TP' against the official Littelfuse datasheet to confirm tape-and-reel packaging or specific binning variations. Ensure the ordering part number matches the exact electrical parameters required for the design, as suffixes may indicate packaging differences rather than functional changes. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and lead-free terminal plating specifications before finalizing procurement.

Triacs Selection Notes

Select this component when an 800V blocking voltage and 12A continuous current capacity are required in a standard TO-220AB isolation package. Consider the 10 mA gate trigger current for compatibility with available drive signals. Evaluate thermal management needs given the 125°C maximum operating temperature and the need for adequate heat sinking in flange-mounted configurations. Verify that the dv/dt rating of 150 V/us meets the transient voltage requirements of the specific AC line application.

Triacs Part Context

The Q8012LH2TP belongs to the Littelfuse Triac family, specifically categorized under analog mixed-signal ICs and triggering devices. It shares the core electrical specifications of the Q8012LH2 series but includes the 'TP' suffix, which typically denotes a specific packaging configuration such as tape and reel for automated assembly. This component is part of Littelfuse's broader portfolio of power control solutions designed for reliable AC switching in various electronic systems.

Triacs Replacement Considerations

Direct replacements must match the 800V/12A rating and TO-220AB package. Check equivalent parts from other manufacturers for compatible gate trigger currents and holding currents. Ensure any substitute maintains the same pinout and isolation characteristics for direct board replacement without redesign.
