Q2010R5

Triacs Overview

The Littelfuse Q2010R5 is a bidirectional triac from the Teccor Electronics line, designed for AC switching and phase control applications. It features an RMS on-state current rating of 10 A and a repetitive peak blocking voltage (VDRM) of 200 V. The device utilizes an electrically isolated TO-220 package, providing a minimum high potential test of 2500 V ac rms between the leads and the mounting tab. Key electrical parameters include a DC gate trigger current (IGT) of 50 mA across quadrants I, II, and III, and a maximum off-state leakage current (IDRM) of 0.05 mA at 25 °C. The component supports a peak one-cycle surge current (ITSM) of 350 A at 60 Hz.

Triacs Feature Summary

• Electrically isolated construction with a mounting tab separated from the semiconductor chip to facilitate low-cost assembly and eliminate external insulators.
• Glass-passivated junctions provide a rugged barrier against contamination, ensuring long-term device reliability and parameter stability.
• Capable of gate triggering from blocking to conduction state for either polarity of applied main terminal voltage.

Triacs Applications

• Speed modulation controls
• Temperature modulation controls
• Lighting controls
• Static switching relays

Triacs Procurement Notes

Verify the specific part number suffix against manufacturer documentation to confirm package isolation status and lead configuration. Ensure that the selected variant meets the required voltage and current ratings for the intended circuit design. Confirm compliance with relevant safety standards and RoHS directives prior to integration into final products.

Triacs Selection Notes

Select this component based on the 10 A RMS current capacity and 200 V blocking voltage requirements. The isolated TO-220 package is suitable for applications requiring galvanic isolation between the control circuit and the heat sink. Consider the 50 mA gate trigger current when designing the driving interface to ensure reliable turn-on across all operating quadrants.

Triacs Part Context

This device belongs to the Littelfuse Teccor triac family, which offers a broad range of bidirectional semiconductors. The product line spans current ratings from 0.8 A to 35 A and voltage capabilities up to 1000 V. These components are engineered for robust performance in AC power control environments, utilizing glass-passivated junction technology for enhanced durability.

Triacs Replacement Considerations

Direct substitutes within the same series include Q2010L4 and Q2010N4, which share identical 10 A/200 V specifications but may differ in package isolation or lead form. Verify pinout compatibility and thermal resistance characteristics when cross-referencing with other manufacturers' triacs.
