Overview
The TCET1104 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a transistor output. It provides an isolation voltage of 5000Vrms and operates within a temperature range of -40°C to 100°C. The device utilizes a 4-DIP package with through-hole mounting. Key electrical specifications include a maximum collector-emitter voltage of 70V, a peak forward current of 60mA, and a typical forward voltage of 1.35V. The collector current per channel is rated at 50mA, with a maximum saturation voltage drop of 300mV. The current transfer ratio ranges from 160% to 320% at a forward current of 10mA.
Feature Summary
- Provides high-voltage isolation between input and output circuits using optical coupling technology.
- Features a phototransistor output configured for reliable switching and signal transmission applications.
- Designed for robust performance across a wide industrial operating temperature range.
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits in automated machinery
- Power supply feedback loops
Procurement Notes
Verify the specific suffix code against the manufacturer datasheet to confirm pin configuration and packaging details. Ensure compliance with RoHS3 standards as indicated in official documentation. Confirm that the 4-DIP package dimensions match the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a single-channel transistor output with 5000Vrms isolation is required. Consider the 160-320% current transfer ratio for logic-level interfacing. Verify that the 4-DIP through-hole package fits the assembly constraints compared to surface-mount alternatives like the TCMT1104.
Part Context
This part belongs to the TCET series of optoisolators from Vishay, designed for general-purpose isolation tasks. It shares functional similarities with other Vishay transistor-output isolators but differs in package type and specific electrical ratings. The TCET1104 specifically targets applications needing through-hole mounting solutions.
Replacement Considerations
The TCMT1104 serves as a surface-mount equivalent offering similar electrical characteristics in a 4-SOP package. Direct substitution requires verifying footprint compatibility and ensuring the lower isolation rating of 3750Vrms meets system safety requirements.
