TCET1114

Overview

The TCET1114 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a phototransistor output. It provides galvanic isolation with a rated voltage of 5000Vrms. The device supports a maximum forward current of 60 mA and delivers an output current of 50 mA per channel. It operates within a temperature range of -55°C to 110°C. The component is housed in a 4-DIP package suitable for through-hole mounting.

Feature Summary

Provides high-voltage galvanic isolation between input and output circuits
Features a phototransistor output topology for signal coupling
Rated for high-temperature operation up to 110°C

Applications

Signal coupling in industrial control systems
Isolation interfaces for microcontroller-based designs
General-purpose digital signal transmission across isolated boundaries

Procurement Notes

Verify the specific datasheet version and mechanical dimensions against the 4-DIP package specification before integration. Confirm that the 5000Vrms isolation rating meets the safety requirements of the target application environment. Ensure thermal management strategies account for the 110°C maximum operating temperature limit during continuous operation.

Selection Notes

Select this component when a robust transistor-output isolator is required for moderate-speed digital signals. The wide operating temperature range makes it suitable for harsh environments. Consider the 4-DIP form factor for legacy or through-hole PCB layouts where surface-mount alternatives are not feasible.

Part Context

The TCET1114 belongs to Vishay’s family of high-temperature optocouplers designed for reliable performance in demanding applications. It shares functional similarities with other transistor-output isolators but distinguishes itself through its specific 4-DIP packaging and extended thermal rating compared to standard commercial-grade variants.
