QJ6025LH4TP

Overview

The QJ6025LH4TP is a high-temperature bidirectional triac manufactured by IXYS, designed for robust power control applications. It features a rated repetitive off-state voltage of 600V and an RMS on-state current capacity of 25A. The device utilizes a TO-220AB isolated package to facilitate secure mounting and thermal management. Key electrical characteristics include a holding current maximum of 50mA and a gate trigger voltage of 1.3V. It operates within a junction temperature range from -40°C to +150°C, ensuring reliability in demanding environments.

Feature Summary

• High-temperature operation capability up to 150°C junction temperature
• Isolated TO-220AB package for enhanced safety and mounting flexibility
• Bidirectional switching functionality with 600V blocking voltage
• Stable triggering characteristics with defined gate trigger parameters

Applications

• Industrial motor speed control systems
• High-power heating element regulation
• Solid-state relay modules requiring isolation
• AC power switching circuits in harsh environments

Procurement Notes

Verify the specific suffix LH4TP against official IXYS documentation to confirm exact binning or testing variations. Ensure the supplier provides valid RoHS compliance certificates and original manufacturer traceability. Cross-reference the part number with Littelfuse records following corporate acquisitions to guarantee authenticity and correct technical specifications.

Selection Notes

Select this component when a 600V, 25A bidirectional switch is required in an isolated TO-220AB form factor. Confirm that the application demands high-temperature stability up to 150°C. Verify that the gate drive circuit can supply at least 1.3V and 50mA for reliable triggering. Ensure the thermal design accommodates the power dissipation associated with continuous 25A loads.

Part Context

This triac belongs to the QJ series of high-reliability thyristors produced by IXYS, now part of Littelfuse. The series is engineered for industrial applications requiring durable AC power control. The QJ6025LH4TP specifically addresses needs for isolated, high-current switching in compact packages suitable for panel mounting.

Replacement Considerations

Direct substitutes may include other 600V, 25A isolated triacs in TO-220AB packages from manufacturers like STMicroelectronics or Microchip. Verify pinout compatibility and thermal resistance values before substitution. Check for equivalent gate trigger currents and holding currents to ensure circuit stability.
