PS8821-1-A

Overview

The CEL PS8821-1-A is a high-speed optocoupler featuring a GaAlAs LED input and a PIN photodiode with a high-speed amplifier output. It operates at data rates up to 1 Mbps and provides isolation of 2500 Vrms. The device is housed in an 8-pin SSOP package and supports a maximum operating temperature of +100°C.

Feature Summary

High-speed signal transmission capability
Integrated PIN photodiode and amplifier for analog output
Robust electrical isolation between input and output circuits

Applications

Industrial communication interfaces
Power supply feedback loops
Signal isolation in noisy environments

Procurement Notes

Verify current availability status as the PS8821-1-A may be obsolete. Confirm exact pinout and package dimensions against official datasheets before integration. Ensure replacement components meet identical isolation voltage and speed requirements for system compatibility.

Selection Notes

Select this component for applications requiring fast digital or analog signal isolation. Consider the 1 Mbps bandwidth limit and 2500 Vrms isolation rating. Evaluate thermal performance within the specified operating range and ensure the 8-pin SSOP footprint fits the design constraints.

Part Context

This part belongs to the CEL PS8821 series of high-speed photocouplers. It shares architectural similarities with other variants like the PS8821-2, differing primarily in output configuration. The series is designed for reliable data transmission across isolated boundaries in compact packages.
