ISP827BL

Overview

The ISP827BLXG is a high-density, dual-channel phototransistor optocoupler manufactured by Isocom Components. It features a plastic DIP-8 package and provides a minimum isolation voltage of 5300 Vrms. The device includes two separate channels with a nominal current transfer ratio of 200% and a maximum dark power of 100 nA. It operates within a temperature range of -55 °C to 100 °C and has a collector-emitter breakdown voltage of at least 35 V. The component is lead-free, RoHS compliant, and holds UL recognition (File No. E91231) and VDE approval.

Feature Summary

• Dual-channel configuration for independent signal isolation
• High insulation capability with 5300 V isolation rating
• Compliant with UL and VDE safety standards

Applications

• Logic-to-logic isolation in noisy environments
• Line receiver circuits
• Programmable current level sensors
• Digital control of motors and servo machines
• Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix against official documentation, as variations such as 'X' or 'BL' may indicate differences in lead form or packaging configuration rather than functional changes. Confirm that the procurement source provides valid UL and VDE certification records. Ensure the component meets RoHS directives and lead-free requirements specified in the datasheet before integration into final assemblies.

Selection Notes

Select this component when high-density mounting and robust electrical isolation are required for dual-channel applications. The 5300 V isolation rating makes it suitable for demanding industrial environments. Consider the DIP-8 package constraints and the -55 °C to 100 °C operating temperature range to ensure compatibility with the target system's thermal and spatial requirements.
