Overview
The PS2833-1-V-A is a single-channel optocoupler from the NEPOC series, manufactured by Renesas Electronics Corporation. It features a GaAs light-emitting diode coupled to an NPN silicon Darlington phototransistor output. The device provides 2500Vrms isolation voltage and supports a maximum collector-to-emitter voltage of 350V. Key electrical parameters include a typical current transfer ratio of 2000% at 1mA forward current, with a maximum DC forward current of 50mA and a typical forward voltage of 1.2V. The unit operates within a temperature range of -55°C to 100°C and is housed in a compact 4-SSOP package.
Feature Summary
- High collector-to-emitter voltage capability up to 350V for robust signal isolation
- Compact 4-pin Shrink Small Outline Package (SSOP) design for high-density mounting
- High current transfer ratio ensuring efficient signal transmission between circuits
Applications
- Hybrid integrated circuit designs requiring galvanic isolation
- Telephone and telegraph receiver systems
- Fax machine interface circuits
Procurement Notes
Verify that the specific suffix 'V' corresponds to the required safety certification approvals, such as UL or CSA listings, as indicated in official documentation. Confirm the package variant matches the 4-SSOP form factor. Ensure compliance with RoHS3 standards and check moisture sensitivity level requirements for storage and handling procedures before assembly.
Selection Notes
Select this component when a high-voltage Darlington output is necessary for driving loads directly without additional amplification stages. The 350V collector-to-emitter rating distinguishes it from lower-voltage variants like the PS2832 series. Consider the 4-SSOP footprint for space-constrained PCB layouts where standard SOP packages do not fit.
Part Context
This part belongs to the PS2833 family of high-voltage optocouplers. It shares the same internal Darlington transistor architecture as the quad-channel PS2833-4 but offers a single channel configuration. The 'V' suffix typically denotes specific safety agency approvals compared to other suffixes in the product line.
