Overview
The PS2833-1-F3-A is a single-channel optoisolator featuring a Darlington transistor output, manufactured by Renesas Electronics Corporation. It provides an isolation voltage of 2500Vrms and operates within a temperature range of -55°C to 100°C. The device supports a maximum DC forward current of 50 mA with a typical forward voltage of 1.2 V. Output specifications include a collector-emitter saturation voltage of up to 1 V and a maximum output voltage of 350 V. The current transfer ratio ranges from 400% to 4500% at 1 mA input. Typical switching times are 20 µs for rise and 5 µs for fall. It is housed in a 4-SSOP surface-mount package.
Feature Summary
- High current transfer ratio capability suitable for low-input drive applications
- Wide operating temperature range supporting harsh industrial environments
- Compact surface-mount packaging for automated assembly
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix F3-A against the official Renesas datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure compliance with RoHS3 standards and check moisture sensitivity level classifications prior to storage and handling. Confirm that the 4-SSOP package dimensions match the target PCB footprint requirements.
Selection Notes
Select this component when high gain is required due to the Darlington output structure, which offers superior current transfer compared to standard phototransistors. Consider the slower switching speeds inherent to Darlington configurations when designing for high-frequency signal transmission. Evaluate thermal management needs given the power dissipation limits within the small SSOP package.
Part Context
This part belongs to the NEPOC series of optocouplers from Renesas Electronics. It is designed for general-purpose isolation tasks where high sensitivity is prioritized over speed. The product line emphasizes reliability in industrial and consumer electronics applications requiring robust electrical separation between circuits.
Replacement Considerations
Public confirmed substitute part numbers: PS2733-1-F3-A (similar Darlington output but different switching characteristics). Verify compatibility regarding isolation voltage ratings and package dimensions before substitution.
FAQ
What is the typical current transfer ratio for this device?
The current transfer ratio typically ranges from 400% to 4500% when tested at a forward current of 1 mA.
Does this optocoupler support high-speed switching applications?
No, the Darlington output results in longer rise and fall times (typically 20 µs and 5 µs), making it unsuitable for high-frequency data transmission.
