QJ6025NH5RP

Triacs Overview

The Littelfuse QJ6025NH5RP is a bidirectional triac in the QJxx25xHx series, rated for 600 V repetitive off-state voltage and 25 A RMS on-state current. It operates within a junction temperature range of -40 °C to +150 °C. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 50 mA. The device exhibits an on-state voltage of 1.8 V and a leakage current of 10 µA at rated voltage. Packaged in a TO-263 (D2-Pak) form factor with reel packaging, it is designed for high-temperature applications requiring robust AC switching capabilities.

Triacs Feature Summary

• High-temperature operation capability up to +150 °C
• Integrated Alternistor structure eliminating external snubber requirements
• Glass-passivated junctions for parameter stability

Triacs Applications

• AC motor speed control circuits
• Industrial heating element regulation
• Solid-state relay output stages

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure the procurement channel provides valid RoHS compliance documentation. Cross-reference the part number with Littelfuse official catalogs to distinguish between tube and reel packaging variants before finalizing orders.

Triacs Selection Notes

Select this component when a 600 V rating and 25 A continuous current are required in a surface-mount D2PAK footprint. Consider the 50 mA gate trigger current for driver compatibility. Evaluate thermal management solutions suitable for operation up to +150 °C junction temperature. Compare against similar QJ series devices if different current or voltage ratings are needed.

Triacs Part Context

This part belongs to the Littelfuse QJ series of Alternistors, which integrate a diac-like trigger mechanism. This design simplifies circuit topology by removing the need for discrete triggering components or complex snubber networks often required with standard triacs. The series targets industrial applications demanding reliable phase control.

Triacs Replacement Considerations

QJ6025NH4TP shares identical electrical ratings but differs in packaging configuration.
