PS8601L

Overview

The PS8601L is an 8-pin high-speed photocoupler from the NEPOC series, manufactured by CEL. It integrates a Gallium Aluminum Arsenide (GaAlAs) LED on the input side with a PN photodiode and a high-speed amplifier transistor on the output side within a single chip. This configuration provides logic IC output functionality with a maximum isolation voltage of 5000 V. The device supports a wide operating temperature range from -55 °C to 100 °C and features CMOS compatibility.

Feature Summary

• High-speed response capability for efficient signal transmission
• High isolation voltage ensuring robust electrical separation between circuits
• CMOS compatible logic output interface

Applications

• Industrial control systems requiring galvanic isolation
• Communication equipment signal interfaces
• Microprocessor system isolation barriers

Procurement Notes

Verify the specific suffix (e.g., E3, E4) against the manufacturer's current datasheet to confirm lead-free status and packaging type. Confirm availability as some variants may be discontinued or subject to allocation. Ensure the selected package matches the required surface mount footprint specifications.

Selection Notes

Select this component when high-speed digital isolation is required in compact surface-mount designs. The integrated amplifier transistor offers improved noise immunity compared to basic phototransistor outputs. Verify that the 5000 V isolation rating meets the safety requirements of the target application environment.

Part Context

This part belongs to the NEC/CEL NEPOC series of high-speed optocouplers. It shares architectural similarities with the PS8601 (DIP package) and PS8601L1/L2 (long creepage variants). The series is designed for applications demanding fast switching speeds and reliable isolation in space-constrained PCB layouts.
