Overview
The PS8501L2-E3-AX is a high-speed analog output optocoupler from the NEPOC series, manufactured by Renesas Electronics Corporation. It features a single channel with a GaAlAs LED input and a PN photodiode combined with a high-speed amplifier transistor on the output side. The device provides 5000Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum forward current of 25 mA, a typical forward voltage of 1.7 V, and an output current of 8 mA. The minimum current transfer ratio is 15% at 16 mA. It utilizes an 8-SMD gull-wing surface mount package.
Feature Summary
- Integrates a GaAlAs LED with a PN photodiode and high-speed amplifier transistor on a single chip for high-speed analog output.
- Provides robust electrical isolation with a 5000Vrms insulation voltage rating.
- Features a wide operating temperature range suitable for demanding industrial environments.
Applications
- Industrial automation control systems
- Power supply feedback loops
- Signal isolation in noisy environments
Procurement Notes
Verify the specific suffix E3-AX against the official Renesas datasheet to confirm lead-free compliance and packaging type. Ensure the 8-SMD gull-wing package matches your PCB footprint requirements. Confirm RoHS3 status and moisture sensitivity level (MSL 1) during component selection. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when high-speed analog signal transmission with galvanic isolation is required. The integrated amplifier transistor offers higher speed compared to standard transistor outputs. Consider the 8-SMD package size for space-constrained designs. Verify that the 5000Vrms isolation meets system safety standards. Check the CTR specifications against the driving circuit capabilities.
Part Context
This part belongs to the PS8501 series, which includes variants like PS8501, PS8501L1, and PS8501L3. These are high-speed photocouplers designed for applications requiring fast response times. The L2 variant specifically denotes the surface-mount package configuration. The series is part of Renesas' NEPOC lineup, focusing on reliability and performance in industrial and automotive sectors.
Replacement Considerations
Check for direct substitutes within the PS8501 family, such as PS8501L1 or PS8501L3, depending on package preference. Verify pinout compatibility and electrical characteristics before substitution. Consult the official replacement guide for any discontinued variants.
