PS2701A-1-F4-A

Overview

The PS2701A-1-F4-A is a single-channel optically coupled isolator manufactured by California Eastern Laboratories (CEL). It integrates a Gallium Arsenide (GaAs) infrared light emitting diode with an NPN silicon phototransistor to provide electrical isolation. The device features a high insulation voltage rating of 3,750 Vrms and supports a collector-emitter voltage of 70 V. It operates within a temperature range of -55°C to +100°C and is housed in a lead-free SOP-4 surface-mount package.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits using optical transmission.
Integrates a GaAs LED emitter with an NPN silicon phototransistor for efficient signal transfer.
Designed for surface-mount assembly in a compact SOP-4 package.

Applications

Industrial control systems requiring circuit isolation
Measurement equipment signal interfacing
Power supply feedback loops

Procurement Notes

Verify the manufacturer designation matches California Eastern Laboratories (CEL) or its successor entity Renesas Electronics, as production rights have transferred. Confirm the suffix F4-A corresponds to the specific tape-and-reel packaging and lead-free compliance requirements. Ensure the datasheet version aligns with current specifications, particularly regarding insulation ratings and thermal characteristics, before finalizing procurement orders.

Selection Notes

Select this component when a single-channel isolation solution with a 3,750 Vrms rating is required in a small footprint. It is suitable for applications needing galvanic separation between low-voltage logic and higher-voltage power stages. Consider the operating temperature range up to 100°C for environments with elevated thermal loads. Verify that the NPN phototransistor output configuration meets the specific switching speed and load requirements of the target circuit design.

Part Context

This part belongs to the PS2701A series of high-isolation voltage SOP photocouplers originally developed by NEC and now managed by CEL/Renesas. The series is designed for general-purpose isolation tasks where space constraints necessitate surface-mount technology. Similar parts in the family include variants with different output configurations or pinouts, such as the PS2801-1.
