Overview
The PS2833-4-F3-A is a quad-channel optocoupler from Renesas Electronics, featuring an NPN silicon Darlington phototransistor output and a GaAs infrared LED input. It provides 2500Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. The device supports DC input with a maximum forward current of 50mA and typical rise/fall times of 20µs/5µs. Packaged in a 16-pin SSOP, it offers a minimum current transfer ratio of 400% at 1mA input.
Feature Summary
- Quad-channel configuration for multi-signal isolation
- High gain NPN Darlington transistor output stage
- Wide operating temperature range suitable for industrial environments
Applications
- Industrial automation control systems
- Power supply feedback loops
- Signal isolation in measurement equipment
Procurement Notes
Verify the specific suffix F3-A against the manufacturer's latest datasheet to confirm package dimensions and reel specifications. Ensure compatibility with RoHS3 standards as indicated in public documentation. Cross-reference the part number with official Renesas distributors to confirm current availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when high current transfer gain is required for driving loads directly without additional amplification. The quad-channel layout reduces board space compared to single-channel alternatives. Verify that the 2500Vrms isolation rating meets the safety requirements of the target application circuit design.
Part Context
This part belongs to the PS2833 series of optocouplers designed for general-purpose isolation. It complements other Renesas optical isolators by offering a four-channel solution in a compact surface-mount package. The series is engineered for reliability in noisy electrical environments common in industrial and consumer electronics.
Replacement Considerations
Check for direct pin-compatible substitutes such as the PS2833-1 variant if fewer channels are needed. Verify equivalent isolation voltage and CTR specifications when considering cross-brand replacements to ensure circuit performance remains unchanged.
