Overview
The PS2535L-1-F3-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN Photodarlington output and provides 5000 Vrms insulation voltage. The device supports a maximum collector-emitter voltage of 350 V and a maximum collector current of 120 mA. Typical current transfer ratio (CTR) is 1500%, with a range of 400% to 5500%. Forward voltage is 1.4 V at 50 mA forward current. Rise time is 18 µs and fall time is 5 µs. Maximum power dissipation is 70 mW. Operating temperature ranges from -55°C to +100°C.
Feature Summary
- High isolation voltage capability for safe signal transmission across isolated circuits
- High collector-to-emitter voltage rating suitable for demanding switching applications
- NPN photodarlington output structure providing high current gain
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal isolation in noisy environments
Procurement Notes
Verify the manufacturer designation, as this part number appears in catalogs for both Renesas Electronics and California Eastern Labs (CEL). Confirm the specific datasheet version matches your design requirements. Check availability status, as some distributors list this component as discontinued or substitute it with parametric equivalents. Ensure the package type matches the PCB footprint specifications.
Selection Notes
Select this component when high voltage isolation and high collector voltage are required. The NPN photodarlington output offers high sensitivity and gain. Consider the rise and fall times for speed requirements. Verify thermal management needs against the 70 mW power dissipation limit. Ensure the operating temperature range meets environmental conditions.
Part Context
This component belongs to the PS2535L series of optocouplers. It is designed for general-purpose isolation applications. The L suffix typically indicates a gull-wing lead bending model for surface mount installation. It serves as a replacement for older DIP versions in modern PCB designs.
Replacement Considerations
Parametric equivalents may be available from other manufacturers. Verify pinout compatibility and electrical parameters before substitution. Some sources list this part as discontinued; check for direct replacements from the same family.
