Q2015R5

Triacs Overview

The Littelfuse Q2015R5 is a Teccor brand bidirectional triac thyristor designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 200 V and an on-state RMS current (It RMS) of 15 A. The device supports non-repetitive peak on-state currents of 167 A and 200 A, with a maximum holding current (Ih) of 70 mA. Gate triggering specifications include a voltage (Vgt) of 2.5 V and currents of 50 mA or 75 mA. Operating within a temperature range of -40°C to +125°C, it utilizes a TO-220-2 through-hole package.

Triacs Feature Summary

• Integrated gate-controlled bidirectional switching capability for AC circuits
• High thermal stability supporting operation up to 125°C junction temperature
• Glass-passivated junctions ensuring parameter stability and long-term reliability

Triacs Applications

• AC motor speed controls
• Temperature modulation systems
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific datasheet revision and ordering suffixes when sourcing. Confirm RoHS compliance status and lead times directly with Littelfuse or authorized distributors. Ensure the TO-220-2 package matches the target PCB footprint requirements before finalizing procurement orders.

Triacs Selection Notes

Select this component for low-voltage AC switching requiring 15 A continuous current. Verify that the 200 V rating exceeds the peak line voltage in the application. Compare gate sensitivity requirements against the 50 mA to 75 mA trigger current specifications to ensure compatibility with the driving circuitry.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx15xx series of standard triacs. These devices are widely used in consumer appliances and industrial controls. The TO-220-2 package provides robust mechanical mounting and thermal dissipation capabilities suitable for medium-power AC regulation tasks.

Triacs Replacement Considerations

Check for direct equivalents such as the Q2015R5TP variant. Evaluate other 200 V, 15 A triacs from Littelfuse or competitors like STMicroelectronics if pinout and electrical parameters match exactly.
