Overview
The PS2535L-1-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared LED with an NPN silicon photodarlington detector, providing high isolation voltage of 5000 Vrms. Key electrical parameters include a typical current transfer ratio (CTR) of 1500%, with a minimum of 400% and maximum of 5500%. The device supports a maximum forward current of 50 mA and a collector-emitter saturation voltage of 1 V. It operates within a temperature range of -55°C to +100°C and features rise/fall times of 18 µs/5 µs.
Feature Summary
- High current transfer ratio capability for efficient signal transmission
- Robust insulation performance with 5000 Vrms isolation rating
- Wide operating temperature range suitable for industrial environments
Applications
- Industrial automation control systems
- Power supply feedback loops
- Solid-state relay drivers
Procurement Notes
Verify the specific suffix F3-A corresponds to the required tape and reel packaging configuration. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure the ordering part number matches the exact pinout and package variant required for the PCB layout design.
Selection Notes
Select this component when high CTR and fast switching speeds are required in a compact surface-mount package. Compare against standard PS2535L variants if different packaging or lead-free specifications are needed. Evaluate thermal dissipation requirements given the 70 mW power dissipation limit at elevated temperatures.
Part Context
This part belongs to the PS2535L series of optically coupled isolators. The series combines GaAs LEDs with NPN photodarlington outputs. The PS2535L-1-F3-A specifically denotes the surface-mount version with defined packaging characteristics. It serves as a key component for galvanic isolation in electronic circuits requiring reliable signal transfer across potential differences.
Replacement Considerations
Check for direct substitutes within the PS2535L family such as PS2535L-1-A if packaging differences are acceptable. Verify pin compatibility and electrical parameter overlaps before substituting with other manufacturers' darlington output optocouplers.
