Overview
The PS2733-1-V-F3-A is a transistor output optocoupler manufactured by Renesas Electronics. It features a single channel with an NPN phototransistor output in a 4-pin SOP package. The device provides high isolation voltage of 3750 Vrms and supports a maximum collector-emitter voltage of 350V. It operates within a temperature range of -55°C to 100°C. Key electrical parameters include a minimum current transfer ratio of 1500% at 1mA, a maximum forward current of 50mA, and a typical forward voltage of 1.15V. The saturation voltage is limited to 1V, with rise and fall times typically at 100µs.
Feature Summary
- High current transfer ratio for efficient signal transmission
- Wide operating temperature range suitable for harsh environments
- Compact surface mount packaging for space-constrained designs
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal isolation in microprocessor interfaces
Procurement Notes
Verify the specific suffix 'V-F3-A' against official Renesas documentation to ensure correct tape and reel configuration and compliance status. Confirm that the requested quantity matches the standard factory packaging specifications to avoid handling discrepancies. Always cross-reference the latest datasheet revision for any updates in mechanical dimensions or thermal characteristics prior to final procurement.
Selection Notes
Select this component when high current gain is required due to its superior CTR compared to standard phototransistors. Ensure the application voltage does not exceed the 350V collector-emitter rating. Consider the 100µs switching speed limitations for high-frequency applications. Verify that the SOP-4 footprint aligns with the PCB layout requirements and that the thermal management strategy accommodates the specified power dissipation limits.
Part Context
This part belongs to the PS2733 series of transistor output optocouplers from Renesas. It is designed for general-purpose isolation tasks where high reliability and wide temperature operation are critical. The series offers various packaging options and electrical ratings to suit different system requirements while maintaining consistent performance standards across the product line.
Replacement Considerations
Check for direct pin-compatible alternatives within the Renesas PS27xx family that may offer updated packaging or slightly different electrical characteristics. Ensure any substitute maintains the same isolation voltage and current transfer ratio specifications to guarantee circuit functionality without redesign.
