IS3020SMT&R

Overview

The IS3020SMT&R is a surface mount optoisolator manufactured by Isocom Components 2004 LTD. It features a six-pin package with a non-zero crossing triac output designed for AC load control. The device provides an isolation voltage of 5300Vrms and supports a peak repetitive off-state voltage of 400V. It operates within a temperature range of -40°C to 100°C and accepts a maximum DC forward current of 60mA.

Feature Summary

• Non-zero crossing triac output configuration for reliable AC switching
• High isolation voltage rating of 5300Vrms
• Surface mount packaging for automated assembly

Applications

• AC load switching circuits
• Solid state relay interfaces
• Industrial control systems requiring galvanic isolation

Procurement Notes

Verify the manufacturer part number IS3020SMT&R against official Isocom Components documentation to ensure authenticity. Confirm that the specific suffix matches the required tape and reel or cut tape format. Check for any obsolescence notices or lifecycle changes directly from the supplier before finalizing procurement plans.

Selection Notes

Select this component when non-zero crossing switching is acceptable for the application, as it may generate higher electromagnetic interference compared to zero-crossing variants. Ensure the circuit design accommodates the 400V peak off-state voltage limit. Verify that the surface mount footprint aligns with the PCB layout requirements for the six-pin SMD package.

Part Context

This device belongs to the family of optoisolators utilizing light coupling for signal transmission between isolated circuits. It serves as a bridge between low-voltage control logic and high-voltage AC loads, providing electrical safety through dielectric isolation while maintaining signal integrity in noisy environments.
