PS2832-1-A

Overview

The PS2832-1-A is a single-channel optocoupler from the CEL NEPOC series, featuring a GaAs infrared LED coupled to an NPN silicon Darlington transistor output. It provides high isolation voltage of 2500Vrms and supports a maximum collector-emitter voltage of 300V. The device operates with a typical forward voltage of 1.2V and delivers an output current of 60mA per channel. Designed for robust signal transmission in electrically noisy environments, it ensures reliable data transfer across isolated circuits.

Feature Summary

High isolation voltage capability for safe circuit separation
Darlington output configuration for enhanced current gain
Compact SOP-4 package with lead-free construction

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops
Signal transmission between microcontrollers and high-voltage loads

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm lot codes and date codes against current production standards. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Check for obsolescence status as some variants may be discontinued. Validate pinout compatibility before integration into existing PCB designs.

Selection Notes

Select this component when high isolation voltage and Darlington output gain are required. Consider thermal dissipation limits and operating temperature range during design. Evaluate current transfer ratio requirements for specific application needs. Ensure input current limits are respected to prevent LED degradation. Compare alternative packages if space constraints exist.

Part Context

Part of the CEL NEPOC series, designed for general-purpose isolation applications. Manufactured by CEL (formerly NEC Electronics), known for reliable optoelectronic components. The PS2832-1 variant specifically denotes a single-channel configuration within the broader PS2832 family.

Replacement Considerations

Check for direct substitutes like PS2832-1-F3 or PS2832-1-A equivalents from other manufacturers. Verify pin compatibility and electrical parameters match original specifications. Consider availability and lifecycle status of potential replacements.
