PS2802-1-V-A

Overview

The PS2802-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN photodarlington output and operates with a DC input. The device provides an isolation voltage of 2500 Vrms. Key electrical parameters include a typical current transfer ratio (CTR) of 2000% at a forward current of 1 mA, a maximum collector-emitter saturation voltage of 1 V, and a maximum collector current of 100 mA. The unit is housed in a compact 4-pin SSOP package with a pin pitch of 1.27 mm.

Feature Summary

• High isolation voltage capability for safe signal transmission between circuits
• High current transfer ratio ensures efficient coupling with low input drive requirements
• Compact surface-mount packaging facilitates dense circuit board layouts

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated grounds

Procurement Notes

Verify the specific suffix 'V' against official Renesas documentation to confirm lead-free status or specific tape-and-reel specifications. Ensure compatibility with RoHS directives if required by your manufacturing process. Cross-reference the exact part number with authorized distributors to confirm current availability and authenticity, as supply conditions may vary.

Selection Notes

Select this component when high current transfer ratio is critical for driving loads with minimal input current. The 2500 Vrms isolation rating suits applications demanding robust barrier protection. Consider the 4-pin SSOP footprint for space-constrained designs. Verify that the photodarlington output speed meets the system's timing requirements, as darlington structures typically exhibit slower switching speeds compared to standard transistors.

Part Context

This part belongs to the PS2802 series of high-isolation optocouplers from Renesas. The series utilizes a small thin package design to minimize board area while maintaining high dielectric strength. The PS2802-1 variant specifically denotes a single-channel configuration within this family, offering a balance of performance and compactness for general-purpose isolation tasks.

Replacement Considerations

Check for direct substitutes such as PS2802-1-F3-A or PS2802-1-K-A, ensuring pinout and electrical characteristics match. Verify package compatibility and insulation clearance requirements before substitution.
