Q6025K6TP

Triacs Overview

The Littelfuse Q6025K6TP is a 25 Amp Alternistor triac with a 600V blocking voltage, housed in an isolated TO-218AC (SMTO-218) package. It features an RMS on-state current of 25A and supports peak non-repetitive surge currents of 208A at 50Hz or 250A at 60Hz. The device requires a maximum gate trigger current of 80mA and operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum on-state voltage of 1.8V, a holding current of 100mA, and a critical rate-of-rise of off-state voltage of 600V/µs.

Triacs Feature Summary

• Alternistor technology enables high commutation performance for inductive loads without requiring external snubber networks.
• Isolated mounting tab design facilitates direct heat sinking while providing electrical isolation from the circuit ground.
• Glass-passivated junctions ensure long-term parameter stability and durability under harsh operating conditions.

Triacs Applications

• AC solid-state switching relays
• Industrial power tools motor speed controls
• Temperature modulation controls for heating systems

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the package type and packing mode. The 'TP' suffix indicates tube packaging. Ensure the procurement documentation matches the exact part number to avoid receiving non-isolated variants or different sensitivity levels within the same series.

Triacs Selection Notes

Select this component when high commutation capability is required for inductive loads without snubber circuits. The isolated TO-218AC package is suitable for applications needing thermal management via a heatsink while maintaining electrical isolation. Verify that the 80mA gate sensitivity aligns with the driving circuit capabilities.
