Overview
The TCET4100G is a quad phototransistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a Darlington transistor output configuration housed in a 16-DIP package. The device provides electrical isolation with an insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter saturation voltage of 300 mV, a reverse voltage rating of 6 V, and power dissipation of 265 mW. It operates within a temperature range of -40°C to +100°C.
Feature Summary
- Quad channel architecture for multi-circuit isolation
- Darlington output structure for high current transfer ratio
- Extra low coupling capacitance typical of 0.2 pF
- High common mode rejection capability
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission across isolated ground planes
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific ordering suffix and package variant against the official Vishay datasheet before procurement. Ensure that the selected component matches the required pinout and thermal specifications for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and availability status.
Selection Notes
Select this component when high current gain is required from a single LED input due to the Darlington output stage. Consider the 16-DIP package dimensions for PCB layout constraints. Evaluate the 5000 Vrms isolation rating against system safety requirements. Confirm that the operating temperature range meets the environmental conditions of the intended deployment scenario.
Part Context
The TCET4100G belongs to Vishay's TCET series of optocouplers, which are designed for robust signal isolation. This model specifically offers four independent channels within a single package, distinguishing it from dual-channel variants like the TCET2200G. The series emphasizes low coupling capacity and stable performance across varying temperatures.
Replacement Considerations
Direct substitutes may include other quad Darlington output optocouplers from Vishay or competitors such as the PC847 series. Verify pin compatibility and electrical ratings before substitution. Consult the official Vishay replacement guide for qualified alternative part numbers.
