TIC108M-S

Scrs Overview

The Bourns TIC108M-S is a silicon controlled rectifier (SCR) in the TIC108 series, housed in a TO-220 package. It features a glass-passivated wafer and offers a repetitive peak off-state voltage of 600 V. The device supports a continuous on-state current of 5 A and an average on-state current of 3.2 A at 180° conduction angle. Surge on-state current capability reaches 20 A. Key electrical parameters include a maximum gate trigger current of 1 mA and a holding current ranging from 2 mA to 15 mA depending on temperature. Junction-to-case thermal resistance is 3.5 °C/W.

Scrs Feature Summary

• Glass passivation provides protection against mechanical stresses and moisture ingress.
• High surge current capability allows handling of transient overloads.
• Low gate trigger current facilitates efficient control circuitry design.

Scrs Applications

• General purpose phase control circuits
• Lighting dimmer applications
• Motor speed control systems

Scrs Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and packaging details upon receipt. Ensure storage conditions remain within specified limits to maintain performance integrity before installation.

Scrs Selection Notes

Select this component for designs requiring 600 V blocking capability with moderate current handling. Evaluate thermal management requirements based on the junction-to-case resistance. Consider derating curves for ambient temperatures exceeding 80°C to ensure reliable operation under continuous load conditions.

Scrs Part Context

The TIC108 series represents a legacy line of silicon controlled rectifiers originally introduced in 1971. This specific part number belongs to a family designed for general-purpose switching applications. The series has been officially marked as obsolete by the manufacturer.

Scrs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official obsolescence notices for recommended modern equivalents or alternative manufacturers offering similar specifications.

Scrs FAQ

What is the maximum repetitive peak reverse voltage for the TIC108M-S?

The maximum repetitive peak reverse voltage (VRRM) for the TIC108M-S is 600 V.

How does case temperature affect the continuous on-state current rating?

The continuous on-state current rating applies up to a case temperature of 80°C. Above 80°C, the current must be derated linearly to zero at 110°C.

What is the typical gate trigger voltage at room temperature?

At a case temperature of 25°C, the typical gate trigger voltage (VGT) is 0.6 V, with a maximum of 1 V.
