TCET1109

Overview

The TCET1109 is a high-temperature optocoupler manufactured by Vishay Semiconductor Opto Division. It features a phototransistor output and provides electrical isolation of 5000Vrms across a single channel. The device supports through-hole mounting in a 4-DIP package. Key electrical parameters include a maximum collector-emitter voltage of 70V, a peak forward current of 60mA, and a typical forward voltage of 1.39V. The unit operates within a temperature range of -40°C to 100°C.

Feature Summary

Designed for reliable data transmission in noisy environments
Optimized for high-temperature operational stability
Provides robust galvanic isolation between input and output circuits

Applications

Industrial control systems requiring noise immunity
High-temperature electronic circuit isolation
DC signal transmission applications

Procurement Notes

Verify the specific suffix codes against official Vishay documentation to ensure correct pinout and performance characteristics. Confirm that the selected variant matches the required thermal rating and package style for your PCB layout. Cross-reference the datasheet revision history to account for any recent manufacturing changes or parameter updates before finalizing procurement.

Selection Notes

Select this component when high-temperature resilience and standard phototransistor output are required. Ensure the application voltage does not exceed the 70V collector-emitter limit. Verify that the 4-DIP through-hole package aligns with the assembly process. Consider the CNY17 series if surface-mount options are preferred instead.

Part Context

This part belongs to the Vishay optocoupler family, specifically designed for general-purpose isolation tasks. It shares functional similarities with other Vishay transistor-output isolators but distinguishes itself through its specific high-temperature rating and through-hole packaging configuration suitable for durable industrial applications.
