Overview
The PS8502L3-V-E3-AX is a high-speed optocoupler from the Renesas PS8502L3 series, featuring an AlGaAs LED input and a phototransistor with base output. It provides 5000 Vrms isolation voltage and supports data rates up to 1 Mb/s. The device operates within a temperature range of -55°C to +100°C, with a typical current transfer ratio of 15% at 16 mA forward current. It is housed in an 8-SMD gull wing package.
Feature Summary
- High common-mode rejection ratio for noise immunity
- Integrated base drive for improved switching speed
- AlGaAs LED technology for long-term reliability
Applications
- Industrial communication interfaces
- Power supply feedback loops
- Signal isolation in noisy environments
Procurement Notes
Verify the specific suffix 'V-E3-AX' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compliance with RoHS directives as indicated by the E3 suffix. Cross-reference the part number with official Renesas documentation to avoid confusion with similar PS8502 variants that may have different electrical characteristics or pin configurations.
Selection Notes
Select this component when high-speed digital isolation is required alongside robust common-mode noise rejection. The integrated base drive distinguishes it from standard phototransistor optocouplers, offering faster response times suitable for data rates up to 1 Mb/s. Consider the 5000 Vrms isolation rating for safety-critical applications requiring strong galvanic separation between input and output circuits.
Part Context
This part belongs to the PS8502L3 family of high-speed photocouplers. It shares the core architecture with PS8502, PS8502L1, and PS8502L2 but features specific packaging and termination variations denoted by the suffix. The L3 variant typically indicates a specific reel packaging configuration for surface-mount assembly.
Replacement Considerations
Direct substitutes include PS8502L1-AX and PS8502L2-V-E3-AX from the same Renesas family, provided pin compatibility and electrical specifications match the design requirements. Verify isolation voltage and data rate capabilities before substitution.
