Q2010L4

Triacs Overview

The Littelfuse Q2010L4 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 maximum DC gate trigger current (IGT) of 25 mA across quadrants I, II, III, and IV, and a peak one-cycle surge current (ITSM) capability of 150 A at 60 Hz. The component operates within a junction temperature range of -40 °C to +125 °C.

Triacs Feature Summary

• Electrically isolated construction with a mounting tab isolated from the semiconductor chip
• Glass-passivated junctions for long-term reliability and parameter stability
• Bidirectional gate triggering capability across all four operating quadrants

Triacs Applications

• Speed modulation controls
