TCET1113

Overview

The TCET1113 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a phototransistor output. It provides an isolation voltage of 5000Vrms and operates within a temperature range of -55°C to 110°C. The device utilizes a 4-DIP package with a pitch of 7.62mm. Key electrical specifications include a maximum collector-emitter voltage of 70V, a DC forward current limit of 60mA, and a typical forward voltage of 1.39V. The saturation voltage is capped at 400mV, while the current transfer ratio ranges from 100% to 200% at a test current of 10mA. Switching characteristics include typical turn-on and turn-off times of 3µs and 2.3µs, respectively.

Feature Summary

• High-voltage insulation capability rated at 5000Vrms for safe signal transmission across isolated circuits.
• Wide operating temperature range extending from -55°C to 110°C for robust performance in demanding environments.
• Fast switching response with defined turn-on and turn-off times suitable for digital signal isolation applications.

Applications

• Industrial control systems requiring galvanic isolation
• Measurement and testing equipment interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific datasheet revision and component marking against official Vishay documentation before integration. Confirm that the 4-DIP package dimensions align with the target PCB footprint. Ensure that thermal management strategies account for the specified operating temperature limits during continuous operation. Cross-reference the isolation voltage ratings with system safety requirements to guarantee compliance with relevant electrical standards.

Selection Notes

Select this component when high isolation voltage and wide temperature tolerance are required for transistor-output applications. Consider the 4-DIP form factor for through-hole mounting constraints. Evaluate the current transfer ratio and switching speeds against the specific signal integrity needs of the circuit design. Ensure compatibility with the driving logic levels and load conditions present in the target application environment.

Part Context

The TCET1113 belongs to the broader family of Vishay optoisolators designed for general-purpose isolation tasks. It shares functional similarities with other devices in the series but is distinguished by its specific package type and electrical ratings. This component serves as a critical interface element in systems where electrical separation between input and output stages is mandatory for safety or noise reduction purposes.

Replacement Considerations

Publicly confirmed substitute part numbers include CNY17-3X009T and VO610A-3. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure that any replacement maintains the required isolation voltage and package dimensions for the existing assembly.
