Q2008NH4RP

Triacs Overview

The Littelfuse Q2008NH4RP is a bidirectional triac designed for high-voltage AC switching applications. It features an 8 A RMS on-state current and a rated repetitive off-state voltage of 2 kV, making it suitable for demanding power control environments. The device operates within a junction temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical characteristics include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The on-state voltage is specified at 1.6 V, with leakage currents limited to 20 uA under rated conditions.

Triacs Feature Summary

• High voltage blocking capability up to 2 kV for robust AC line isolation
• Surface-mount SMTO-263-2 packaging for automated assembly integration
• Defined gate sensitivity with standardized trigger parameters

Triacs Applications

• Industrial motor speed control systems
• High-power heating element regulation
• Solid-state relay output stages

Triacs Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm voltage rating and package variant. Ensure compatibility with existing thermal management designs due to the SMD form factor. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a 2 kV blocking voltage is required alongside an 8 A continuous current capacity in a compact surface-mount footprint. Compare against lower voltage variants if system insulation requirements are less stringent. Evaluate thermal dissipation needs based on the 1.6 V on-state voltage drop and expected load duty cycles.

Triacs Part Context

This triac belongs to the Qxx08xHx series from Littelfuse, which standardizes the 8 A current rating across various voltage classes. The 'Q' prefix typically denotes a specific thyristor family optimized for industrial reliability. This model represents the highest voltage option within the 8 A SMD lineup, distinguishing it from 800 V or 1000 V counterparts.

Triacs Replacement Considerations

Direct replacements must match the 2 kV rating, 8 A current, and SMTO-263-2 package. Verify pinout compatibility and thermal resistance values. Cross-reference with other manufacturers offering equivalent high-voltage SMD triacs only if datasheet parameters align precisely.
