ISP824XSMT&R

Overview

The ISP824XSMT&R is a dual-channel optocoupler manufactured by Isocom Components 2004 LTD. It features an AC input configuration paired with phototransistor outputs, housed in an 8-pin surface mount DIP package. The device provides a high isolation voltage of 5300Vrms and supports a maximum forward current of 50 mA per channel. Designed for robust signal transmission across isolated circuits, it offers a typical current transfer ratio of 20%.

Feature Summary

• Dual-channel architecture enabling simultaneous signal isolation for two independent circuits within a single compact package.
• AC input compatibility allows direct interfacing with alternating current sources without requiring additional rectification components.
• High-voltage insulation capability ensures safe electrical separation between input and output sides in noisy environments.

Applications

• Solid-state relays
• Industrial control systems
• Power supply units

Procurement Notes

Verify the specific suffix 'SMT&R' confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the AC input specification aligns with your circuit design, as standard DC input variants exist within the same product family. Ensure the 8-SMD package dimensions match your PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation is required with AC-compatible inputs. The phototransistor output type suits applications needing moderate switching speeds. Consider the 5300Vrms isolation rating for safety-critical interfaces. Verify thermal management requirements for surface mount installation to ensure reliable operation under continuous load conditions.

Part Context

Isocom Components specializes in providing alternative optocoupler solutions, often replacing obsolete parts from other manufacturers. The ISP824 series represents their surface mount offerings designed for modern PCB assembly techniques. This specific model targets markets requiring reliable galvanic isolation in compact form factors.

Replacement Considerations

Check pinout compatibility if substituting with other dual-channel SMD optocouplers. Verify that the replacement part supports AC input signals, as many alternatives are DC-only. Ensure the isolation voltage and current transfer ratio meet or exceed the original specifications for equivalent performance.
