TIC116D-S

Scrs Overview

The Bourns TIC116D-S is an obsolete Silicon Controlled Rectifier (SCR) in a TO-220 package, rated for 400 V repetitive peak off-state and reverse voltage. It supports 8 A continuous on-state current at case temperatures up to 70°C and handles 80 A surge current. The device features a maximum gate trigger current of 20 mA and operates within a junction-to-case thermal resistance of 3 °C/W. Designed with glass passivation, it functions reliably across an operating case temperature range of -40°C to +110°C.

Scrs Feature Summary

• Glass passivated wafer construction for enhanced durability
• TO-220 surface mount compatible package with mounting base electrical contact
• Guaranteed gate control characteristics for reliable triggering

Scrs Applications

• Industrial motor controls
• Power supply regulation circuits
• Lighting dimming systems

Scrs Procurement Notes

This component is officially classified as obsolete by the manufacturer and is not recommended for new designs. Verification of availability should focus on surplus distributors or legacy stock rather than standard manufacturing channels. Ensure that any sourced units match the original specifications, as replacement alternatives may require circuit modifications.

Scrs Selection Notes

Select this part only for maintenance or repair of existing equipment where the original design constraints are fixed. For new projects, consider modern equivalents with updated thermal ratings or higher voltage margins. Verify that the 400 V rating aligns with the specific system's peak transient requirements and that the 8 A current capacity meets the load demands under derating conditions.

Scrs Part Context

The TIC116 series represents a legacy line of silicon controlled rectifiers from Bourns, originally introduced in 1971 and revised through 2002. This specific model belongs to a family designed for general-purpose power switching applications before being phased out in favor of newer technologies. Its historical significance lies in its widespread use in mid-20th-century industrial electronics.

Scrs Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the official documentation. Engineers must identify cross-references based on matching electrical parameters such as 400 V blocking voltage, 8 A RMS current, and TO-220 packaging compatibility.

Scrs FAQ

What is the maximum gate trigger current for the TIC116D-S?

The maximum average gate trigger current (IGT) is specified as 20 mA under test conditions of VAA = 12 V, RL = 100 Ω, and tp(g) ≥ 20 µs.

How does the device handle thermal dissipation?

The junction-to-case thermal resistance (RθJC) is typically 3 °C/W, while the junction-to-free air thermal resistance (RθJA) is 62.5 °C/W. Continuous DC operation requires derating above 70°C case temperature.

Is the TIC116D-S suitable for new designs?

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