TCET1106

Overview

The TCET1106 is a single-channel photovoltaic output optoisolator manufactured by Vishay Semiconductor Opto Division. It provides electrical isolation with a rated voltage of 5000Vrms. The device features a DC input and transistor output configuration housed in a 4-DIP package. Key electrical parameters include a minimum current transfer ratio of 100% at 5mA forward current, with a maximum CTR of 300%. Typical switching times are specified as 6µs for turn-on and 5µs for turn-off, while rise and fall times are typically 3µs and 4.7µs respectively.

• Power supply feedback loop isolation

Procurement Notes

Verify the specific suffix or variant against the official Vishay datasheet to ensure exact electrical characteristics match the design requirements. Confirm package dimensions and pinout alignment with PCB footprints prior to procurement. Check for any recent product change notices regarding manufacturing location or material composition updates.

Selection Notes

Select this component when high isolation voltage is required in a small form factor. Ensure the application current does not exceed the maximum ratings defined in the datasheet. Consider the thermal performance and ambient operating temperature range during system design to maintain reliability under varying load conditions.

Part Context

This component belongs to the Vishay optoisolator family, designed for reliable signal transmission across isolated barriers. It serves as a critical interface element in systems requiring galvanic separation between low-voltage control circuits and higher-voltage power stages, ensuring safety and noise immunity.

Replacement Considerations

Direct substitutes may include other Vishay models within the same series offering identical pinouts and electrical specifications. Verify that alternative components meet the same isolation voltage and current transfer ratio requirements before implementation.
