Overview
The PS2701-1-F3 is a transistor output optocoupler featuring a GaAs infrared LED and an NPN silicon phototransistor. It provides high isolation voltage of 3,750 Vrms between input and output circuits. The device utilizes a Small Outline Package (SOP) for compact integration. Typical switching characteristics include a rise time of 3 μs and a fall time of 5 μs at a forward current of 5 mA. The maximum collector-emitter voltage is rated at 40V, with a current transfer ratio up to 300% under specified conditions.
Feature Summary
- High isolation voltage capability of 3,750 Vrms
- Compact SOP package design
- High-speed switching performance
Applications
- General purpose signal isolation
- Microprocessor interface circuits
- Industrial control systems
Procurement Notes
Verify the specific suffix codes against manufacturer documentation to confirm exact packaging and lead time requirements. Ensure compatibility with SOP-4 footprint specifications during PCB layout. Confirm operating temperature ranges align with system environmental constraints before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and compact form factor are required. Verify that the 40V output voltage rating meets circuit demands. Consider the typical 3 μs rise time for signal integrity in high-speed digital applications. Ensure input current limits are respected to maintain optimal current transfer ratio performance.
Part Context
This part belongs to the PS2701 series of multi photocouplers manufactured by CEL and Renesas. The series includes variants with different package types and electrical characteristics. The PS2701-1-F3 specifically denotes the SOP package version with standard switching speeds. It is designed for reliable galvanic isolation in electronic circuits.
Replacement Considerations
Check datasheets for equivalent parts from other manufacturers offering similar 3,750 Vrms isolation and SOP-4 packages. Verify pinout compatibility and electrical parameters such as CTR and switching times before substitution.
