TIC116M-S

Scrs Overview

The TIC116M-S is an obsolete silicon controlled rectifier from the TIC116 series, manufactured by Bourns Inc. It features a glass-passivated wafer and operates in a TO-220 package with three terminals: Anode, Gate, and Cathode. The device supports a repetitive peak off-state voltage of 600 V and a continuous on-state current of 8 A at case temperatures at or below 70°C. It handles an 80 A surge current under specific conditions. Key electrical characteristics include a maximum gate trigger current of 20 mA and a holding current ranging from 40 to 100 mA depending on temperature. The component is rated for an operating case temperature range of -40°C to +110°C.

Scrs Feature Summary

• Glass passivation provides protection against environmental stressors.
• Robust surge capability allows handling of high transient currents.
• Direct thermal contact between the mounting base and Pin 2 facilitates heat dissipation.

Scrs Applications

• Industrial motor control systems
• Power supply regulation circuits
• Lighting dimmer applications

Scrs Procurement Notes

This component is officially marked as obsolete and not recommended for new designs. Verification of availability should focus on surplus distributors rather than primary manufacturing channels. Engineers must confirm that existing stock meets all original datasheet specifications before integration into legacy maintenance projects.

Scrs Selection Notes

Designers requiring active alternatives should evaluate modern thyristor families offering similar voltage and current ratings. Considerations must include updated thermal resistance values, improved gate sensitivity, and compliance with current environmental directives. Verify pinout compatibility if substituting directly into existing PCB layouts.

Scrs Part Context

The TIC116 series represents an older generation of silicon controlled rectifiers designed for general-purpose power switching. While historically significant for industrial applications, the entire series has been discontinued by the manufacturer. The TIC116M-S specifically denotes the 600 V variant within this lineup.

Scrs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult manufacturer catalogs for current SCR equivalents matching 600 V and 8 A specifications.

Scrs FAQ

What is the maximum gate trigger current for the TIC116M-S?

The maximum average gate power dissipation is 1 W, with a peak gate current of 3 A for pulses up to 300 µs. The gate trigger current (IGT) has a maximum value of 20 mA.

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

The 8 A rating applies at or below 70°C case temperature. Above 70°C, the current must be derated linearly to zero at 110°C.

Is the TIC116M-S suitable for new design implementations?

No, the datasheet explicitly states that the TIC116 series is obsolete and not recommended for new designs.
