Overview
The ISP827BSM is a surface-mount, dual-channel transistor output optocoupler manufactured by Isocom Components. It features a plastic DIP-8 package and provides 5300 Vrms isolation voltage between input and output circuits. The device utilizes NPN phototransistor outputs with a nominal current transfer ratio of 200%. It operates within a temperature range of -55°C to 100°C and supports a maximum forward current of 50 mA. Key approvals include UL recognition (File No. E91231) and VDE 0884 certification.
Feature Summary
- Dual-channel configuration for independent signal isolation
- High-density surface-mount packaging for compact circuit design
- Certified safety isolation meeting UL and VDE standards
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in noisy electrical environments
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify the specific lead form suffix 'B' against official Isocom documentation to confirm pinout and mechanical dimensions. Ensure compliance with RoHS directives and check for any specific handling requirements related to the plastic DIP-8 package during assembly processes.
Selection Notes
Select this component when dual-channel isolation is required in a single package footprint. Consider the 5300 Vrms isolation rating for high-voltage applications. Verify that the NPN phototransistor output characteristics align with the receiving circuit's logic levels and switching speed requirements.
Part Context
This part belongs to the ISP827 series of high-density mounting phototransistor optically coupled isolators. It shares family characteristics with other models like ISP817 and ISP847 but offers dual-channel functionality distinct from single-channel variants. The series is designed for reliable performance in industrial and commercial electronic equipment.
Replacement Considerations
Check for direct substitutes within the ISP827 series or equivalent dual-channel optocouplers from other manufacturers. Ensure replacement parts match the DIP-8 package, 5300 Vrms isolation rating, and NPN output type. Verify that any alternative maintains the same UL and VDE safety certifications.
