PS8101-V-F3-K-AX

Overview

The PS8101-V-F3-K-AX is a high-speed optocoupler from the Renesas NEPOC series, designed for applications requiring robust signal isolation. It integrates a GaAlAs LED on the input side with a PIN photodiode and high-speed amplifier transistor on the output side within a single chip. The device supports data rates up to 1 Mbps and offers a high common-mode transient immunity of ±15 kV/μs. It operates with a supply voltage up to 35 V and provides an isolation voltage of 3750 Vrms. The component is housed in a compact 5-pin SOP package, suitable for high-density PCB layouts.

Feature Summary

• High common-mode transient immunity for reliable noise rejection
• Compact plastic SOP-5 package for high-density mounting
• Integrated high-speed amplifier transistor for fast response
• High isolation voltage capability for safety-critical circuits

Applications

• Industrial communication interfaces
• Power supply feedback loops
• Motor control systems
• Signal isolation in noisy environments

Procurement Notes

Verify the specific suffix 'K' against official Renesas documentation to confirm if it denotes a unique tape-and-reel specification or packaging variant distinct from standard versions. Ensure the ordering code matches the exact datasheet revision required for your design. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when high-speed digital isolation is required alongside significant common-mode noise immunity. The 1 Mbps data rate and low propagation delay make it suitable for modern serial communication protocols. Consider the 5-pin SOP footprint for space-constrained designs where traditional optocouplers may be too large. Ensure the operating temperature range meets the environmental requirements of the target application.

Part Context

This device belongs to the NEPOC (NEC Photocoupler) family, now managed by Renesas Electronics following the acquisition of CEL. The PS8101 series is specifically engineered for analog and digital isolation applications requiring high speed and reliability. It represents a transition from discrete components to integrated optocouplers with built-in amplification for improved performance.

Replacement Considerations

Check for direct substitutes within the PS8101 series such as PS8101-F3 or PS8101-V-AX, ensuring pin compatibility and electrical specifications match. Verify if alternative manufacturers offer equivalent high-speed optocouplers with similar isolation voltages and data rates.
