PS2833-1-A

Overview

The PS2833-1-A is a single-channel optocoupler from the NEPOC series, manufactured by Renesas Electronics Corporation. It features a GaAs infrared LED coupled to an NPN silicon Darlington phototransistor output. The device provides high isolation voltage of 2500Vrms and supports a collector-emitter voltage up to 350V. Key electrical parameters include a typical current transfer ratio of 2000% at 1mA forward current, with a maximum DC forward current of 50mA. The unit operates within a temperature range of -55°C to 100°C and is available in a compact 4-SSOP surface-mount package.

Feature Summary

• Integrates a GaAs light emitting diode with an NPN silicon Darlington-connected phototransistor for optical signal transmission.
• Provides high collector-to-emitter voltage capability of 350V for robust circuit isolation.
• Features a small and thin Shrink Small Outline Package (SSOP) design suitable for high-density mounting applications.

Applications

• Hybrid IC designs requiring galvanic isolation
• Telephone and telegraph receiver circuits
• Fax machine interface modules

Procurement Notes

Verify the specific suffix designation against official documentation, as standard listings often utilize F3 or F4 variants for tape-and-reel packaging. Confirm RoHS compliance status and safety approvals such as UL, CSA, or VDE requirements relevant to the target application region before finalizing procurement orders.

Selection Notes

Select this component when high voltage isolation and high current transfer ratio are required in a compact form factor. Ensure the input drive current remains within the 50mA maximum limit and verify that the 350V collector-emitter rating exceeds the peak transient voltages present in the isolated circuit environment.

Part Context

This part belongs to the PS2833 series of high collector-to-emitter voltage photocouplers. It shares architectural similarities with the PS2832 series but offers increased voltage tolerance. The NEPOC series designation indicates a specific product line optimized for reliability and density in industrial communication interfaces.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameter equivalence if considering alternative manufacturers for this specific optocoupler configuration.
