Overview
The IS283 is a single-channel optocoupler manufactured by Isocom Components 2004 LTD, housed in a compact 4-pin SOP package. It features a DC input type and a transistor output configuration, designed for signal isolation applications. The device supports a maximum collector-emitter voltage of 80V and provides an isolation voltage rating of 3750Vrms. Key electrical specifications include a minimum current transfer ratio (CTR) of 50% at an input current of 5mA. Typical switching performance is characterized by a rise time of 2µs and a fall time of 3µs, ensuring reliable operation in digital signal transmission circuits requiring galvanic isolation.
Feature Summary
- Provides high-voltage galvanic isolation between input and output circuits
- Features a compact surface-mount SOP package design
- Utilizes a standard transistor output configuration for digital signaling
Applications
- Digital signal isolation in communication interfaces
- Microcontroller input/output protection circuits
- Switching power supply feedback loops
Procurement Notes
Verify the specific ordering suffix to confirm packaging format, as tape and reel options with 3000 pieces per reel are available. Confirm that the selected variant matches the required SOP pinout and lead finish specifications for your PCB assembly process. Ensure compliance with SVHC regulations as indicated in product documentation before finalizing procurement orders.
Selection Notes
Select this component when a low-profile surface-mount solution is required for isolating low-speed digital signals. The 50% CTR at 5mA ensures adequate drive capability for standard logic levels. Consider the 80V collector-emitter voltage limit to ensure compatibility with the load circuit requirements. The 3750Vrms isolation rating provides robust safety separation for general industrial applications.
Part Context
Isocom Components 2004 LTD specializes in infrared optoelectronic devices, offering alternatives to discontinued industry-standard components. The IS283 belongs to their range of photovoltaic and transistor-output optoisolators, designed to meet global manufacturing standards. This part serves as a direct replacement for legacy DIP-based optocouplers in modern surface-mount designs.
Replacement Considerations
Public confirmed substitute part numbers are not explicitly listed in the provided source material for the IS283. Verify pinout compatibility and electrical parameters against existing designs if considering alternative manufacturers.
