Q6012NH5RP

Triacs Overview

The Littelfuse Q6012NH5RP is a bidirectional triac designed for surface-mount applications in the SMTO-263-2 package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (It RMS) of 12 A. The device supports non-repetitive on-state currents of 100 A and 120 A, with a maximum on-state voltage of 1.6 V. Gate triggering requirements include a voltage (Vgt) of 1.3 V and a current (Igt) of 50 mA. The holding current (Ih) is limited to a maximum of 50 mA, while the off-state leakage current remains at 10 uA under VDRM conditions. Operating temperatures range from -40 C to +125 C.

Triacs Feature Summary

• Surface-mount construction in a compact SMTO-263-2 package for automated PCB assembly
• High thermal stability supporting operation up to +125 C junction temperature
• Sensitive gate trigger characteristics enabling direct interface with logic-level control circuits

Triacs Applications

• Solid-state relay modules requiring high-density mounting
• AC motor speed control systems for industrial equipment
• Lighting dimmer circuits for commercial fixtures

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Littelfuse documentation. Confirm that the received units match the specified SMTO-263-2 package and electrical ratings. Ensure storage conditions comply with moisture sensitivity levels defined in the datasheet to maintain solderability and performance integrity during assembly processes.

Triacs Selection Notes

Select this component when a 12 A RMS current rating and 600 V blocking capability are required in a surface-mount form factor. The sensitive gate drive specifications make it suitable for low-power control interfaces. Evaluate thermal management requirements based on the 1.6 V on-state voltage drop and expected load currents to ensure reliable operation within the specified temperature range.

Triacs Part Context

This triac belongs to the Qxx12xHx series from Littelfuse, which focuses on standard high-temperature thyristor solutions. The family provides consistent electrical characteristics across varying voltage and current ratings, allowing designers to scale power handling capabilities while maintaining similar package footprints and gate drive requirements for modular system designs.

Triacs Replacement Considerations

Direct substitutes within the same series include variants with adjusted current or voltage ratings, such as the Q6016NH5RP or Q6010N5RP. Verify pin compatibility and thermal resistance parameters before substitution to ensure circuit performance remains within safe operating limits.
