QK012RH2TP

Triacs Overview

The Littelfuse QK012RH2TP is a bidirectional triac rated for 800V blocking voltage and 12A RMS current. It features a gate trigger voltage of 1.3V and a gate trigger current of 50mA, with a maximum holding current of 50mA. The device exhibits a low on-state voltage of 1.6V and operates within a temperature range of -40°C to +125°C. Packaged in a TO-220-2 (TO-220AB) format, it is designed for surface mount or through-hole applications requiring robust AC power control.

Triacs Feature Summary

• High-voltage bidirectional switching capability for AC load control
• Robust thermal performance supporting high-temperature industrial environments
• Sensitive gate drive requirements facilitating direct interface with logic circuits

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• AC power regulation circuits

Triacs Procurement Notes

Verify the specific suffix 'H2' against official Littelfuse documentation to confirm pinout configuration and package variant. Ensure the selected distributor provides traceable component history. Confirm RoHS compliance status via the manufacturer's latest declaration before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800V rating is required instead of higher voltage variants like the 1kV QK012NH5TP. Verify that the TO-220-2 package fits the PCB layout constraints. Compare gate sensitivity specifications against available driver ICs to ensure reliable triggering under varying temperature conditions.

Triacs Part Context

This part belongs to the Qxx12xHx series of triacs from Littelfuse. It shares the 12A current rating with other family members but differs in voltage blocking capabilities and package style. The H2 suffix typically denotes specific mechanical or electrical variations within the broader Q-series product line.

Triacs Replacement Considerations

Direct substitutes include the Q8012RH2TP which shares identical electrical ratings and package type. Alternative replacements may include the QK012NH5TP if a 1000V rating is acceptable. Verify pin compatibility and thermal resistance values before substituting.
