TCET1600G

Overview

The TCET1600G is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and utilizes a 4-DIP package for through-hole mounting. The device provides high isolation with a rated voltage of 5300 Vrms. Key electrical parameters include a collector-emitter saturation voltage of 300 mV maximum, a forward current of 60 mA maximum, and a forward voltage of 1.25 V typical. The current transfer ratio ranges from 20% to 300%. Operating temperatures span from -40°C to +100°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using a phototransistor configuration.
• Features a robust dielectric barrier capable of withstanding high isolation voltages for safety-critical applications.
• Designed for through-hole integration within standard DIP-4 footprints.

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic gates
• Power supply feedback loops requiring voltage separation

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm exact packaging and compliance status. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest datasheet revisions to confirm active status and any potential pinout or mechanical dimension updates prior to finalizing orders.

Selection Notes

Select this component when high isolation voltage requirements exceed standard 5000 Vrms ratings. Consider the 4-DIP package constraints for PCB layout and thermal management. Evaluate the current transfer ratio range against the driving circuit capabilities to ensure reliable switching performance across the specified temperature range. Confirm that the through-hole mounting style aligns with the assembly process requirements.

Part Context

The TCET1600G belongs to the family of transistor output optoisolators produced by Vishay Semiconductor Opto Division. These devices are engineered for general-purpose isolation tasks where electrical safety and noise immunity are paramount. The product line typically includes variants with different isolation voltages and package styles to accommodate diverse design specifications.

Replacement Considerations

Direct substitutes may include other Vishay models such as TCET1100G or TCLT1600, provided they meet the isolation voltage and package requirements. Verify compatibility regarding current transfer ratio and pin configuration before substitution.
