ISP827-3

Overview

The ISP827-3 is a high-density, dual-channel transistor output optocoupler manufactured by Isocom Components 2004 LTD. It features two independent phototransistor outputs within a single DIP-8 plastic package. The device provides a minimum collector-emitter breakdown voltage of 35 V and supports a maximum forward current of 50 mA. It offers a nominal current transfer ratio of 200% and a maximum dark power dissipation of 100 nA. The unit is rated for an insulation voltage of 5300 V and operates within a temperature range of -55 °C to 100 °C.

Feature Summary

Dual-channel configuration with separate phototransistor outputs in a compact DIP-8 package
High isolation capability rated at 5300 V for enhanced circuit protection
Compliant with UL recognition (File No. E91231) and VDE 0884 standards

Applications

Industrial control systems requiring galvanic isolation
Signal transmission between microcontrollers and peripheral devices
Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm lead form variations such as STD or G forms. Ensure compliance requirements match project specifications, specifically UL and VDE approvals. Confirm pinout compatibility with existing PCB layouts before integration. Cross-reference manufacturer documentation for any recent packaging or specification updates.

Selection Notes

Select this component when dual-channel isolation is required within a limited footprint. The high current transfer ratio suits applications demanding efficient signal coupling. Verify thermal management needs given the 100 °C maximum operating temperature. Consider the 35 V breakdown voltage limit for low-voltage signal interfaces. Evaluate package constraints against available DIP-8 mounting options.

Part Context

This part belongs to the ISP827X series of high-density phototransistor optically coupled isolators. It shares functional similarities with the ISP817 and ISP847 models but offers dual-channel architecture. The series is designed for applications requiring robust electrical isolation in compact electronic assemblies.
