Overview
The PS2702-1-V-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features a Darlington phototransistor output with a maximum collector current of 200 mA and a peak reverse voltage of 40 V. The device provides an insulation voltage of 3750 Vrms and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a minimum current transfer ratio (CTR) of 200% at 1 mA input, a typical turn-on time of 90 µs, and a typical turn-off time of 60 µs. The forward voltage is typically 1.1 V at a maximum DC forward current of 50 mA.
Feature Summary
- High isolation voltage capability of 3750 Vrms for robust circuit protection
- Darlington output configuration providing high current gain and drive capability
- Wide operating temperature range suitable for demanding industrial environments
Applications
- Industrial automation control systems
- Power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix 'V' indicates the required packaging format, as datasheets list both tape-and-reel and cut-tape options. Confirm RoHS compliance status matches project requirements, noting REACH exemption. Check for recent PCN updates regarding label changes or manufacturing site transfers before finalizing orders.
Selection Notes
Select this component when high current drive capability is needed from a low-power control signal. The Darlington output offers higher CTR than standard phototransistors but exhibits slower switching speeds. Ensure the application timing requirements accommodate the microsecond-level rise and fall times specified in the datasheet.
Part Context
This part belongs to the NEPOC series of optocouplers from Renesas. It is designed for general-purpose isolation tasks where moderate speed and high output current are prioritized over ultra-fast switching. The SOP-4 package allows for compact surface-mount integration into various electronic assemblies.
Replacement Considerations
Direct substitutes may include other Renesas PS2702 variants with different packaging suffixes. Cross-brand replacements require matching the 40V Vceo, 200mA Iout, and 3750Vrms isolation rating while verifying pin compatibility.
