Q8012RH2TP

Triacs Overview

The Q8012RH2TP is a bidirectional triac manufactured by Littelfuse, 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 10-10-10 mA gate trigger specification, ensuring compatibility with standard logic interfaces. It is housed in an isolated TO-220AB package, providing robust thermal management and electrical isolation. Key electrical parameters 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. The component operates within a temperature range of -40°C to +125°C and exhibits a critical rate of rise of off-state voltage of 150 V/us.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding AC line applications
• Robust thermal performance via isolated flange-mount packaging
• Standardized gate sensitivity for straightforward driver interface

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'H2TP' against the manufacturer's latest datasheet to confirm pinout configuration and compliance status. Ensure the ordering quantity aligns with the factory tube pack size of 1000 units if bulk procurement is required. Cross-reference the RoHS and REACH declarations with current regulatory requirements before finalizing the purchase order.

Triacs Selection Notes

Select this component when an 800V rating is necessary for high-line voltage environments. The 12A current capacity supports moderate-power loads without excessive heatsinking. Verify that the 10-10-10 mA gate drive characteristics match the available driver circuitry. Consider the TO-220AB package dimensions for PCB layout constraints and thermal dissipation requirements in the final enclosure design.

Triacs Part Context

This part belongs to the Qxx12xHx series of triacs from Littelfuse, which are engineered for general-purpose AC switching. The series offers a balance of voltage handling and current carrying capacity in standard industrial packages. These devices are commonly used in consumer appliances and industrial controls where reliable AC phase control is required.

Triacs Replacement Considerations

Check for direct cross-references such as the Q8012LH2, noting potential differences in packaging or specific electrical tolerances. Confirm that any substitute maintains the same 800V/12A ratings and TO-220AB footprint to ensure mechanical and electrical compatibility.
