Q8016RH3

Triacs Overview

The Littelfuse Q8016RH3 is a bidirectional triac designed for AC power control applications. It features an RMS on-state current of 16 A and a rated repetitive peak off-state voltage of 800 V. The device utilizes a TO-220AB package with a flange mount configuration, providing robust thermal dissipation capabilities. Key electrical parameters include a maximum non-repetitive peak on-state current of 167 A at 50 Hz and 200 A at 60 Hz. The gate trigger voltage maximum is specified at 2 V, while the gate trigger current maximum is 35 mA. The component operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• High surge current capability for handling transient loads
• Flange mount construction for efficient heat transfer
• Insensitive gate characteristics for reliable triggering

Triacs Applications

• Industrial motor speed control systems
• Solid state relays for AC switching
• General purpose AC power regulation circuits

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and thermal pad configuration. Ensure the ordering part number matches the required package variant, as suffixes may indicate differences in packaging or compliance status. Cross-reference with authorized distributors to confirm current availability and lead times.

Triacs Selection Notes

Select this component when high current handling and robust thermal performance are required in a through-hole format. Compare the 800 V rating against system voltage peaks to ensure adequate margin. Evaluate the gate trigger requirements of the driving circuitry against the specified 2 V and 35 mA limits to guarantee proper turn-on under all operating conditions.

Triacs Part Context

This triac belongs to the Littelfuse Q series of high-power thyristors. These devices are engineered for demanding industrial environments where reliability under high stress is critical. The Q8016RH3 specifically targets applications requiring durable AC switching solutions with standardized mounting interfaces for easy integration into existing chassis designs.

Triacs Replacement Considerations

Direct replacements must match the 16 A current rating, 800 V voltage rating, and TO-220AB flange package. Verify that substitute components offer equivalent or superior gate sensitivity and thermal resistance values to maintain system performance.
