TIC126S-S

Scrs Overview

The TIC126S-S is a silicon controlled rectifier from the Bourns Inc. TIC126 series, housed in a TO-220 package. It features a repetitive peak off-state voltage (VDRM) and reverse voltage (VRRM) of 700 V. The device supports a continuous on-state current (IT(RMS)) of 12 A at case temperatures at or below 70°C, with an average on-state current (IT(AV)) of 7.5 A under 180° conduction. Surge on-state current (ITM) reaches 100 A. Electrical characteristics include a maximum gate trigger current (IGT) of 20 mA and a holding current (IH) of 40 mA. Thermal resistance from junction to case (RθJC) is 2.4 °C/W.

Scrs Feature Summary

• Glass passivated wafer construction for enhanced durability
• High surge current capability of 100 A for robust operation
• Guaranteed gate control across specified temperature ranges

Scrs Applications

• Industrial motor controls
• Power supply circuits
• Lighting dimmers

Scrs Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolete status warnings before procurement. Ensure proper handling procedures are followed due to the TO-220 package type and thermal requirements during installation.

Scrs Selection Notes

Select this component when a 700 V SCR rating is required for AC power control applications. Consider the 12 A continuous current capacity and TO-220 mounting options for heat dissipation needs. Evaluate thermal derating curves for operating temperatures above 70°C to ensure reliable performance within specified limits.

Scrs Part Context

The TIC126 series represents a line of silicon controlled rectifiers designed for general-purpose power switching. The TIC126S variant specifically offers a 700 V blocking voltage rating, distinguishing it from other members like the TIC126D (400 V) and TIC126N (800 V). This series has been historically utilized in various industrial and consumer electronics applications requiring reliable phase control.

Scrs Replacement Considerations

This product is marked as obsolete and not recommended for new designs. Verify availability of alternative SCRs with equivalent 700 V ratings and similar current capacities from current production lines.
