IS3052

Overview

The IS3052 is a single-channel optoisolator manufactured by Isocom Components, featuring a triac output designed for high-voltage isolation applications. It provides a robust 5000Vrms isolation voltage between the input and output circuits, ensuring safety in demanding environments. The device operates with a random phase triac output, allowing triggering at any point of the AC line cycle without zero-crossing detection circuitry. It supports an off-state voltage of up to 600V and is housed in a standard 6-DIP package suitable for through-hole mounting.

Feature Summary

• High voltage isolation capability of 5000Vrms
• Random phase triac output for flexible AC control
• Off-state voltage rating of 600V
• Single channel configuration

Applications

• Solid state relays
• AC motor control systems
• Industrial power switching modules
• Lighting control interfaces

Procurement Notes

Verify that the specific order matches the random phase triac output variant, as zero-crossing versions exist within the same family. Confirm the 6-DIP package requirement against board layout constraints. Ensure the 600V off-state voltage meets the peak line voltage requirements of the target application circuit before finalizing procurement.

Selection Notes

Select this component when random phase triggering is required rather than zero-crossing synchronization. The 5000Vrms isolation rating makes it suitable for high-noise industrial environments. Consider the 600V blocking capability for standard mains voltage applications. The DIP-6 package offers easy prototyping and replacement compared to surface-mount alternatives.

Part Context

Isocom Components specializes in replacing discontinued or hard-to-find optocouplers from major manufacturers. The IS3052 serves as a direct functional equivalent to industry-standard triac outputs, maintaining pinout compatibility. This allows designers to migrate existing designs without re-engineering the PCB layout while benefiting from Isocom's manufacturing flexibility.

Replacement Considerations

Check datasheets for compatible parts offering identical pinouts and electrical ratings. Verify that substitute components support random phase operation if zero-crossing is not desired. Ensure the replacement maintains the 5000Vrms isolation and 600V off-state voltage specifications.
