PS8101-K-A

Overview

The CEL PS8101-K-A is a linear IC output optocoupler featuring a single channel with 3750 Vrms isolation voltage. It operates at a data rate of 1 MBps and supports a maximum supply voltage of 35 V. The device utilizes a GaAlAs LED input and a PIN photodiode with a high-speed amplifier transistor output. It is housed in a lead-free plastic SOP-5 package, suitable for high-density surface-mount applications.

Feature Summary

High common mode transient immunity of ±15 kV/μs minimum
Small SOP-5 plastic package design for high density applications
Supports high supply voltage up to 35 V
Includes UL and CSA safety approvals

Applications

High-speed signal isolation in industrial control systems
Analog signal transmission across isolated boundaries
Noise-sensitive digital communication interfaces

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm pinout and electrical characteristics. Confirm current availability status as this part may be obsolete or discontinued. Ensure compliance with RoHS directives if lead-free status is required for the assembly process. Cross-reference safety approval numbers with relevant regulatory bodies before final integration.

Selection Notes

Select this component when high common-mode rejection and fast response times are critical for signal integrity. The SOP-5 package is appropriate for space-constrained PCB layouts requiring surface-mount technology. Consider the 35 V supply limit and 3750 Vrms isolation rating when designing circuits with significant potential differences between input and output domains.

Part Context

This component belongs to the NEC PS8101 series, originally developed by NEC (now CEL). It represents a high-speed analog output type photocoupler designed to replace older discrete isolation solutions. The series is characterized by its integration of a PIN photodiode and amplifier on a single chip, providing enhanced performance over standard transistor-output optocouplers.
