Overview
The PS8501-V-AX is a high-speed optocoupler manufactured by Renesas Electronics. It features one channel with a data rate of 1 Mb/s and an insulation voltage of 5000 Vrms. The output type is a photo IC. Key electrical parameters include a current transfer ratio of 15%, a forward current (If) of 16 mA, a forward voltage (Vf) of 1.7 V, and a reverse voltage (Vr) of 5 V. The output current is 8 mA, with a power dissipation (Pd) of 100 mW. The device operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-speed signal transmission with a data rate of 1 Mb/s for efficient digital isolation.
- Ensures robust electrical safety through a high insulation voltage rating of 5000 Vrms between input and output circuits.
Applications
- Industrial automation systems requiring reliable signal isolation
- Power supply circuits needing feedback isolation
- Communication interfaces demanding high common-mode noise rejection
Procurement Notes
Verify the specific suffix variant against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels and thermal requirements before integration. Cross-reference manufacturer part numbers with distributor catalogs to avoid ordering errors due to similar model designations.
Selection Notes
Select this component when high-speed digital isolation is required alongside significant voltage separation. Consider the photo IC output type for driving subsequent logic stages directly. Evaluate the operating temperature range and power dissipation limits to ensure suitability for the intended environmental conditions and load characteristics.
Part Context
This part belongs to the PS8501 series of high-speed optocouplers from Renesas Electronics. These devices are designed for applications requiring fast switching speeds and strong galvanic isolation. The series typically includes variants with different output configurations and packaging options to suit diverse circuit board layouts and performance needs.
Replacement Considerations
Consult official cross-reference lists for direct substitutes. Verify that any alternative component matches the 1 Mb/s data rate, 5000 Vrms isolation, and photo IC output type. Ensure pinout compatibility and thermal performance align with the original design specifications.
