VOS615A-2X001T

Transistor, Photovoltaic Output Optoisolators Overview

The VOS615A-2X001T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output housed in a compact 4-pin SSOP surface-mount package. The device provides an isolation voltage of 3750 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80 V and a continuous collector current of 50 mA. The current transfer ratio ranges from 63% to 125% at a forward current of 10 mA. Operating temperatures span from -55°C to +110°C, supporting reliable performance in demanding environments.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation via a 3750 Vrms dielectric barrier between the infrared LED input and NPN phototransistor output.
• Utilizes a compact 4-pin SSOP surface-mount footprint designed for automated assembly and space-constrained PCB layouts.
• Delivers fast switching characteristics with typical rise and fall times of 3 µs and 4 µs respectively for signal transmission.

Transistor, Photovoltaic Output Optoisolators Applications

• Solid-state relay interfaces requiring galvanic isolation
• Microcontroller I/O expansion and digital signal isolation
• Power supply feedback loops for voltage regulation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '2X001T' corresponds to the required tape-and-reel packaging configuration, as other suffixes may indicate cut-tape or different reel quantities. Confirm that the 4-SSOP package dimensions align with the target PCB footprint. Ensure the 3750 Vrms isolation rating meets the safety standards applicable to the final equipment design, such as UL or VDE requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution is preferred over through-hole DIP packages within the VO series. The VOS615A-2X001T offers a balance of moderate speed and high isolation voltage suitable for general-purpose digital isolation. Compare against the VO615A-X001 for through-hole needs or the VOS615A-1X001T if different CTR bins are required. Ensure the 50 mA collector current limit suffices for the load connected to the phototransistor.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the Vishay VO series of transistor output optocouplers, which are widely used for general-purpose isolation. The VOS615A variant specifically denotes the surface-mount SSOP version of the standard VO615A through-hole device. This series is characterized by its silicon gate structure and high reliability, making it a standard choice for industrial and consumer electronics applications requiring cost-effective signal isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements within the same manufacturer family include VOS615A-1X001T and VOS615A-4X001T, though these may differ in current transfer ratio specifications or packaging quantity. Cross-brand equivalents should be evaluated based on matching isolation voltage, CTR, and package dimensions.
