Q4025J6TP

Triacs Overview

The Littelfuse Q4025J6TP is a bidirectional triac designed for high-power switching applications. It features an RMS on-state current of 25 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-218 through-hole package. Key electrical parameters include a gate trigger current (Igt) of 80 mA, a gate trigger voltage (Vgt) of 2.5 V, and a maximum holding current of 100 mA. Non-repetitive peak on-state currents are specified at 208 A and 250 A, with an on-state voltage of 1.8 V and a leakage current of 10 uA.

Triacs Feature Summary

• Provides bidirectional conduction for AC power control circuits
• Features isolated construction for enhanced safety in high-voltage environments
• Capable of handling significant surge currents for robust operation

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays for AC load switching
• Lighting dimmer circuits for commercial fixtures

Triacs Procurement Notes

Verify the specific suffix J6TP against official Littelfuse documentation to confirm isolation characteristics and pinout configuration. Ensure that the SMTO-218 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 25 A RMS current rating and 400 V blocking voltage are required in a through-hole format. The 80 mA gate drive requirement must be accommodated by the control circuit design. Consider thermal management solutions suitable for the SMTO-218 package given the 125°C maximum junction temperature limit.

Triacs Part Context

This part belongs to the Littelfuse Qxx25xx series of triacs, which are engineered for general-purpose AC power switching. The Q4025J6TP specifically denotes the 25 A current class with 400 V voltage rating and isolated packaging variant within this product family.

Triacs Replacement Considerations

Direct substitutes may include other 25 A, 400 V isolated triacs in SMTO-218 packages from Littelfuse or compatible manufacturers, provided gate trigger specifications and thermal ratings align with the original design constraints.
