IL206AT

Transistor, Photovoltaic Output Optoisolators Overview

The IL206AT is a single-channel optoisolator featuring an NPN phototransistor with base output in an 8-SOIC package. It provides 4000 Vrms isolation voltage between input and output circuits. The device supports a maximum DC forward current of 60 mA and a collector-emitter saturation voltage of up to 400 mV. Key electrical parameters include a collector-emitter voltage rating of 70 V, a reverse voltage of 6 V, and a power dissipation capacity of 240 mW. The current transfer ratio ranges from 63% to 125%, ensuring reliable signal transmission across the isolation barrier for digital applications.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the ordering suffix matches the specific tape-and-reel or tube packaging configuration required for your assembly line. Confirm that the manufacturer designation aligns with Vishay Semiconductor Opto Division specifications. Ensure the component meets RoHS compliance requirements if mandated by your project standards. Cross-reference the datasheet revision date to guarantee compatibility with current design constraints and parameter tolerances.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single channel with base access is necessary for improved switching speed or gain control. The 70 V collector-emitter rating suits applications involving moderate load voltages. Consider the 60 mA forward current limit when designing drive circuits. The SOIC-8 footprint requires appropriate PCB land pattern dimensions. Evaluate thermal dissipation needs based on the 240 mW power rating under continuous operation conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

The IL206AT belongs to the IL20xAT family of phototransistor output optocouplers manufactured by Vishay. This series includes variants such as the IL205AT, IL207AT, and IL208AT, which share similar structural characteristics but may differ in specific electrical ratings or testing criteria. These devices are designed for surface-mount technology, offering compact solutions for modern electronic assemblies requiring reliable optical isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the same Vishay family include the IL205AT, IL207AT, and IL208AT. Verify pinout compatibility and ensure that alternative part numbers meet the specific voltage and current requirements of the original design. Check datasheets for any differences in current transfer ratio or isolation voltage before implementing a swap.
