TCMT1600T3

Overview

The TCMT1600T3 is a photovoltaic output optoisolator from Vishay Semiconductor Opto Division, designed for electrical isolation and signal transmission between circuits. It features a high voltage isolation capability of 3750Vrms and utilizes a phototransistor output switching function. The device consists of a gallium arsenide infrared-emitting diode optically coupled to a phototransistor within a low-profile surface mount package. Key electrical parameters include a typical forward voltage (Vf) of 1.35V, a maximum collector-emitter saturation voltage (Vce) of 300mV, and a typical coupling capacitance of 0.3 pF. Operating temperatures range from -40°C to 100°C.

Feature Summary

• High voltage isolation capability of 3750Vrms for safe circuit separation
• Low coupling capacitance of 0.3 pF typical value for minimal interference
• Photovoltaic output design with phototransistor switching functionality
• Low temperature coefficient of current transfer ratio for stable performance

Applications

• General purpose digital signal isolation in industrial control systems
• Interface circuits requiring high voltage barrier protection
• Microprocessor system input/output isolation applications

Procurement Notes

Verify the specific ordering suffix matches the required package configuration before procurement. Confirm that the component meets the necessary isolation voltage ratings for the intended application environment. Ensure compatibility with standard surface mount assembly processes. Check for any recent product change notifications regarding manufacturing site transfers or material updates. Validate that the supplier provides authentic components with traceable documentation.

Selection Notes

Select this component when high isolation voltage and low parasitic capacitance are critical requirements. Consider the photovoltaic output type for applications needing galvanic isolation without active pull-up resistors. Evaluate the operating temperature range against environmental conditions. Compare the low saturation voltage characteristics with other transistor output options for efficiency needs.
