Q6025R6TP

Triacs Overview

The Littelfuse Q6025R6TP is a high-reliability Alternistor TRIAC designed for robust AC switching applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (ITRMS) of 25 A. The device utilizes a sensitive gate structure with a maximum DC gate trigger current (IGT) of 60 mA, facilitating direct interfacing with logic circuits. Packaged in an electrically isolated TO-220AB configuration, it offers enhanced thermal management capabilities. Key electrical parameters include a holding current (IH) maximum of 100 mA and an on-state voltage (VTM) of approximately 1.8 V. The component supports a minimum critical rate of rise of off-state voltage (dv/dt) of 30 V/µs and operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Alternistor technology provides superior noise immunity and eliminates the need for external snubber networks in many phase-control applications.
• Electrically isolated TO-220AB package allows direct mounting to heatsinks without additional insulating hardware, simplifying assembly.
• Sensitive gate design enables reliable triggering from low-power control signals, such as those from microprocessors or optocouplers.

Triacs Applications

• Solid-state relays requiring high isolation and noise immunity
• Industrial motor speed controls and soft starters
• Lighting dimmers and temperature modulation systems

Triacs Procurement Notes

Verify the specific suffix 'R6' against official Littelfuse documentation to confirm gate sensitivity and packaging details, as variations exist within the Q6025 series. Ensure the procurement channel sources genuine components with traceable manufacturing data to maintain reliability standards for industrial applications.

Triacs Selection Notes

Select this component when a 600 V, 25 A TRIAC with sensitive gate drive is required in an isolated TO-220 package. Compare dv/dt ratings and holding current specifications against circuit requirements to ensure stable commutation. Verify that the thermal resistance characteristics of the isolated tab suit the intended heatsinking strategy.

Triacs Part Context

This device belongs to the Littelfuse Qxx25xx series of Alternistor TRIACs. These devices are engineered for high-reliability performance in demanding power electronics environments. The series combines standard TRIAC functionality with improved noise immunity and simplified application circuitry due to integrated gate sensitivity.

Triacs Replacement Considerations

Direct replacements may include other 600 V, 25 A isolated TRIACs from manufacturers like STMicroelectronics or Vishay, provided pinouts and electrical parameters match. Verify gate trigger currents and thermal characteristics before substitution.
