Overview
The PS2701-1-F3-Y-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output housed in a 4-pin SOP package. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 80 mA, and a forward voltage of 1.1 V at a forward current of 50 mA. The device offers a high isolation voltage of 3750 Vrms and a typical rise time of 3 µs.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Compact SOP-4 surface mount package design for space-constrained applications
- Fast switching speed with typical rise time of 3 microseconds
Applications
- AC input detection circuits
- Microcomputer input/output interface
- General purpose signal isolation
Procurement Notes
Verify the specific suffix 'F3-Y-A' against official Renesas documentation to confirm pinout and packaging variations. Confirm RoHS compliance status as required by project specifications. Check product lifecycle status to ensure availability for new designs or long-term supply needs.
Selection Notes
Select this component when a single channel of isolation with high CTR and fast switching is required. Ensure the 40 V collector-emitter voltage rating meets the load requirements. Verify that the SOP-4 package dimensions fit the PCB layout constraints compared to through-hole alternatives.
Part Context
This part belongs to the PS2701 series of transistor output optocouplers. The series is characterized by high isolation voltage and small SOP packages. It serves as a standard solution for galvanic isolation in digital communication and control systems where compact size and reliable performance are prioritized.
Replacement Considerations
Consult official substitution lists for direct replacements. Generic equivalents may differ in isolation voltage or switching speed. Verify pin compatibility and electrical ratings before integrating alternative components into existing designs.
