PC849

Overview

The PC849 is a high-density mounting type photocopler manufactured by Sharp Microelectronics. It features four channels with transistor and photovoltaic output configurations, housed in a 16-DIP package. The device provides an insulation voltage of 5000Vrms, ensuring reliable optoisolated transmission for industrial automation applications requiring high isolation.

Feature Summary

• High-density mounting design
• Four-channel configuration
• High insulation voltage capability

Applications

• Industrial automation systems
• Optoisolated signal transmission
• High isolation voltage requirements

Procurement Notes

Verify the specific datasheet version and pinout compatibility before integration. Confirm that the 16-DIP package dimensions match your PCB layout constraints. Ensure the 5000Vrms isolation rating meets your safety standards. Check current availability status as some listings indicate obsolete or limited supply conditions.

Selection Notes

Select this component when multiple isolated channels are required in a compact footprint. The high insulation voltage makes it suitable for noisy environments. Consider the transistor and photovoltaic output types for different load driving needs. Verify thermal management requirements for dense mounting scenarios.

Part Context

This part belongs to Sharp's line of photocouplers designed for robust signal isolation. It serves as a bridge between low-voltage control circuits and higher-voltage power stages. The four-channel architecture allows for complex isolation tasks within a single package, reducing board space compared to discrete solutions.
