ISP827-2SMT&R

Overview

The ISP827-2SMT&R is a surface-mount transistor output optocoupler manufactured by Isocom Components. It features two independent channels within a single DIP-8 plastic package, providing high-density mounting capabilities. The device offers a nominal current transfer ratio of 200% and supports a maximum insulation voltage of 5300 V. It operates reliably across a wide temperature range from -55 °C to +100 °C. Key electrical specifications include a maximum forward current of 0.05 A and a minimum collector-emitter breakdown voltage of 35 V. The component is designed for efficient signal isolation in compact electronic circuits.

Feature Summary

• Dual-channel configuration for high-density circuit design
• High insulation voltage capability for robust signal isolation
• Wide operating temperature range suitable for demanding environments
• Compliant with UL recognition and VDE approval standards

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission between microprocessors and peripheral devices
• Power supply feedback loops for voltage regulation
• Interface circuits in communication equipment

Procurement Notes

Verify the specific suffix '2SMT&R' against official Isocom documentation to confirm the exact lead frame configuration and tape-and-reel packaging details. Ensure that the procurement request explicitly references the dual-channel nature of the ISP827 series to avoid confusion with single-channel variants like the ISP817 or ISP847. Confirm compliance requirements such as RoHS status and specific safety approvals (UL/VDE) relevant to the target application before finalizing orders.

Selection Notes

Select this component when a dual-channel isolation solution is required in a small footprint. The ISP827-2SMT&R is appropriate for applications needing moderate current transfer ratios around 200%. Consider the 5300 V isolation rating for high-voltage separation needs. Evaluate the thermal performance within the -55 °C to +100 °C range to ensure suitability for the intended environmental conditions compared to other optocoupler families.

Part Context

This part belongs to the ISP827 series of high-density mounting phototransistor optically coupled isolators. The series includes various configurations such as ISP817, ISP827, and ISP847, available in different lead forms including STD and G types. The 'X' designation in related datasheets often indicates specific specification approvals. This surface-mount variant integrates two elements into a standard DIP-8 package format adapted for SMD assembly.

Replacement Considerations

Direct substitutes may include other dual-channel optocouplers in DIP-8 packages with similar isolation voltages and CTR ranges. Verify pin compatibility and channel independence. Single-channel replacements would require two separate components. Check if alternative manufacturers offer equivalent high-density dual-channel solutions with matching safety certifications.
