TCDT1102

Overview

The TCDT1102 is a single-channel optocoupler featuring a phototransistor output paired with a gallium arsenide infrared-emitting diode. It utilizes a 6-pin DIP package for through-hole mounting. Key electrical parameters include a maximum collector-emitter voltage (Vceo) of 32V and an isolation voltage of 5000Vrms. The device supports a maximum forward current of 60mA, with a typical rise time of 3μs and a typical fall time of 4.7μs. The current transfer ratio ranges from 63% minimum to 600% maximum. Operating temperatures span from -40°C to 100°C.

Feature Summary

• Provides reliable electrical isolation between input and output circuits via optical coupling.
• Integrates a high-speed phototransistor output for efficient signal transmission.
• Constructed with a gallium arsenide infrared-emitting diode for stable light emission.

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits requiring high-voltage isolation protection
• Digital communication channels needing galvanic separation

Procurement Notes

Verify the specific suffix variant, such as TCDT1102G, against project requirements, as packaging or compliance attributes may differ. Confirm that the 6-pin DIP form factor aligns with existing PCB footprints. Ensure that the 5000Vrms isolation rating meets the safety standards applicable to the target equipment design. Cross-reference the operating temperature range with environmental conditions.

Selection Notes

Select this component when a single channel with phototransistor output is required. The 63% to 600% current transfer ratio offers flexibility for various drive currents. The 32V collector-emitter voltage suits low-voltage logic interfacing. Consider the 3μs rise time for moderate-speed digital applications. The wide operating temperature range supports diverse environmental deployments.

Part Context

The TCDT1102 belongs to the Vishay TCET1100 series of optocouplers. This series is characterized by high-speed performance and robust isolation capabilities. The device represents a standard solution for galvanic isolation in electronic designs where compact size and reliable signal transfer are prioritized over ultra-high speed or multi-channel integration.

Replacement Considerations

The TCDT1102G is listed as a related variant within the same product family. Verify if the 'G' suffix indicates a specific RoHS-compliant packaging change or minor parameter adjustment before substitution. No other direct cross-model substitutes are confirmed in the provided documentation.
