TCET4100

Overview

The TCET4100 is a quad optoisolator manufactured by Vishay Semiconductor Opto Division, featuring four independent channels within a single package. It utilizes a phototransistor output coupled to an infrared-emitting diode, providing robust electrical isolation with a voltage rating of 5000Vrms. The device supports a maximum output voltage of 70V and can handle a continuous output current of 50mA per channel. Designed for through-hole mounting, it is housed in a standard 16-DIP package. The unit operates reliably across an extended temperature range from -55°C to 100°C, ensuring stability in demanding electronic environments.

Feature Summary

• Quad-channel configuration for multi-signal isolation
• High-voltage insulation capability
• Through-hole DIP packaging

Applications

• Industrial control systems requiring signal isolation
• Communication equipment interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to procurement, as manufacturing updates may occur. Confirm that the 16-DIP package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your system's thermal specifications. Cross-reference the part number with official Vishay documentation to confirm availability and any potential obsolescence notices before finalizing orders.

Selection Notes

Select this component when multiple isolated channels are required in a compact form factor. The 5000Vrms isolation rating makes it suitable for high-noise industrial environments. Consider the 16-DIP package for prototyping or applications where surface area allows for through-hole assembly. Evaluate the 50mA output current capacity against load requirements to ensure adequate drive capability without exceeding limits.

Part Context

The TCET4100 belongs to Vishay’s family of transistor-output optoisolators, designed for general-purpose digital and analog signal isolation. It shares design principles with other Vishay optocouplers but distinguishes itself through its quad-channel architecture. This configuration reduces board space compared to using four separate single-channel devices, offering a streamlined solution for complex isolation needs in consumer and industrial electronics.
