Overview
The IS3021SMT&R is a surface-mount optoisolator manufactured by Isocom Components 2004 LTD. It features a single channel with a triac output device. The component provides an isolation voltage of 5300Vrms and supports a maximum blocking voltage of 400V. It operates with a non-zero crossing characteristic and utilizes a 6-pin DIP-style SMD package.
Feature Summary
- Non-zero crossing triac output for precise load control
- High isolation voltage rating of 5300Vrms
- Surface mount packaging for automated assembly
Applications
- Solid-state relay circuits
- AC motor control systems
- Industrial process control interfaces
Procurement Notes
Verify the manufacturer designation as Isocom Components 2004 LTD against official datasheets. Confirm the specific suffix R indicates reel packaging if required. Ensure the non-zero crossing variant matches the application requirements rather than zero-crossing types.
Selection Notes
Select this component when non-zero switching is required for AC loads. The 400V blocking voltage suits low-voltage AC applications. Verify thermal management needs for surface mount operation within specified temperature ranges.
Part Context
This part belongs to the IS3021 series of optocouplers. It integrates an infrared LED emitter with a triac detector. The design facilitates electrical isolation between control circuits and high-power AC loads in compact form factors.
Replacement Considerations
Check for compatible triac-output optocouplers with matching 5300Vrms isolation and 400V blocking voltage. Verify pinout compatibility for direct replacement in existing PCB layouts.
