ISP827ASM

Overview

The ISP827ASM is a dual-channel transistor output optocoupler manufactured by Isocom Components. It features an infrared LED coupled to NPN silicon phototransistors in an 8-pin DIP plastic package. Key electrical parameters include a maximum isolation voltage of 5300 Vrms, a minimum current transfer ratio of 80%, and a collector-emitter breakdown voltage of 35 V. The device operates within a temperature range of -55°C to 100°C and supports a maximum forward current of 50 mA.

Feature Summary

• Dual-channel configuration for independent signal isolation
• High insulation capability with 5300 Vrms isolation voltage
• NPN silicon phototransistor output structure

Applications

• Logic-to-logic isolation in noisy environments
• Industrial control systems
• Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix ASM against official Isocom documentation to confirm pinout compatibility and package dimensions. Ensure that the required current transfer ratio and isolation voltage meet the target circuit design specifications before procurement. Cross-reference UL and VDE recognition status if safety certification is mandatory for the application.

Selection Notes

Select this component when dual-channel isolation is required within a standard DIP footprint. Consider the 80% minimum CTR for logic level interfacing and the 5300 Vrms rating for high-voltage separation needs. Evaluate thermal management requirements given the 100°C maximum operating temperature limit.
