TCET2200G

Overview

The TCET2200G is a dual-channel transistor output optocoupler from Vishay, housed in an 8-pin PDIP package. It features NPN phototransistor outputs with a maximum collector-emitter voltage of 70 V and a continuous collector current of 50 mA. The device provides 5000 Vrms insulation voltage and operates within a temperature range of -40°C to +100°C. Key electrical parameters include a forward current of 60 mA, forward voltage of 1.6 V, and a current transfer ratio ranging from 50% to 600%. Power dissipation is rated at 250 mW, with a collector-emitter saturation voltage of 300 mV.

Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• High insulation voltage capability for safety-critical applications
• NPN phototransistor output structure for standard logic interfacing

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated ground planes

Procurement Notes

Verify the specific suffix 'G' corresponds to the RoHS-compliant variant as indicated by manufacturer documentation. Confirm that the 8-pin DIP package matches the PCB footprint requirements. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the current transfer ratio specifications against the application's noise immunity needs.

Selection Notes

Select this component when dual-channel isolation is required within a single package to save board space. The NPN output type is suitable for sinking current loads. Consider the 5000 Vrms isolation rating for applications demanding high dielectric strength between input and output circuits. Evaluate the thermal performance based on the 250 mW power dissipation limit under worst-case operating conditions.

Part Context

The TCET2200G belongs to the broader category of transistor output optocouplers manufactured by Vishay Semiconductor Opto Division. It serves as a solution for electrically isolating low-voltage control circuits from higher-voltage power stages. The dual-channel design distinguishes it from single-channel counterparts, offering integrated isolation for paired signals.

Replacement Considerations

Direct substitutes may include other Vishay dual-channel optocouplers with similar pinouts and electrical ratings. Verify compatibility regarding isolation voltage, current transfer ratio, and package dimensions before substitution.
