Overview
The PS2802-4-V-A is a four-channel transistor output optocoupler manufactured by Renesas Electronics. It features NPN photodarlington outputs and operates with a DC input. The device provides an isolation voltage of 2500 Vrms and is housed in a 16-pin SSOP package. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 100 mA, and a forward voltage of 1.4 V at a forward current of 50 mA. The typical rise and fall times are both 200 μs, with a current transfer ratio ranging from 200% to 2000%. The operating temperature range spans from -55°C to +100°C.
Feature Summary
- Four independent channels for multi-signal isolation
- High isolation voltage capability of 2500 Vrms
- NPN photodarlington output configuration
- Wide operating temperature range
Applications
- Industrial control systems requiring signal isolation
- Measurement equipment input/output interfaces
- Power supply feedback loops
- Communication interface isolation
Procurement Notes
Verify the specific suffix 'V-A' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with existing PCB footprints for the 16-SSOP package. Check for RoHS compliance status as indicated in official documentation before finalizing procurement orders.
Selection Notes
Select this component when high channel density and robust isolation are required. The photodarlington output offers high current gain but slower switching speeds compared to standard phototransistors. Consider the 2500 Vrms isolation rating for safety-critical applications. Verify that the 40 V collector-emitter voltage meets the load requirements.
Part Context
This part belongs to the PS2802 series of high isolation voltage darlington type photocouplers. It is designed for surface mount applications using the SSOP-16 package. The series is intended for general-purpose isolation tasks where compact size and high reliability are prioritized over high-speed switching performance.
Replacement Considerations
The PS2802-4-F3-A is a documented variant within the same family, offering similar electrical characteristics but potentially different packaging or certification details. Verify functional equivalence regarding pinout and electrical ratings before substitution.
