Overview
The TCET1100 is a single-channel phototransistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a DIP-4 through-hole package with an isolation voltage of 5000Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70V, a typical forward voltage of 1.6V, and a maximum forward current of 60mA. The device exhibits a typical rise time of 3μs and a fall time of 4.7μs. It operates within a temperature range of -40°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Features low coupling capacitance for enhanced noise immunity
- Offers high common mode rejection capabilities
Applications
- General-purpose signal isolation in industrial control systems
- Microcontroller interface circuits requiring galvanic separation
- Power supply feedback loops for safety isolation
Procurement Notes
Verify the specific suffix (e.g., G) against the datasheet to confirm RoHS compliance status. Ensure the ordering part number matches the required CTR binning if precise gain characteristics are critical for the design. Confirm package type and lead form match the PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a single channel with moderate speed and high isolation voltage is required. Compare CTR ranges against other TCET110x variants to ensure sufficient gain margin for the load. Verify that the 60mA forward current limit accommodates the driving circuit's output capability without exceeding absolute maximum ratings.
Part Context
This component belongs to the TCET1100 series of Vishay's phototransistor optocouplers. The series offers various Current Transfer Ratio (CTR) bins to suit different sensitivity requirements while maintaining consistent electrical characteristics such as switching times and isolation voltage across the family.
Replacement Considerations
Direct substitutes include TCET1100G for RoHS-compliant versions. Other members of the TCET1100 series may be compatible if their specific CTR ranges align with the application's gain requirements.
