PS9124-V-AX

Logic Output Optoisolators Overview

The PS9124-V-AX is a high-speed optocoupler manufactured by Renesas Electronics Corporation. It features a single channel with an open collector output type, housed in a 5-pin SOP (SO-5) package. The device supports data rates up to 10 Mb/s and provides an insulation voltage of 3750 Vrms. Key electrical parameters include a forward current of 10 mA, a forward voltage of 1.55 V, and an output current of 25 mA. The component operates within a temperature range of -40°C to +100°C, with rise and fall times of 20 ns and 5 ns respectively.

Logic Output Optoisolators Feature Summary

• High common-mode transient immunity of 10 kV/µs for reliable signal transmission in noisy environments
• Integrated LED driver circuitry simplifies interface design and reduces external component count
• Complies with CSA safety standard CAN/CSA C22.2 62368-1 for industrial equipment safety

Logic Output Optoisolators Applications

• Industrial automation control systems requiring galvanic isolation
• Power supply feedback loops for noise immunity
• Communication interfaces in electric vehicles and charging stations

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'V' against the manufacturer's official documentation to confirm compliance with relevant safety standards such as UL or CSA. Ensure the SO-5 package dimensions match the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The integrated LED driver makes it suitable for applications where simple logic-level interfacing is needed without complex external drive circuits. Consider the 3750 Vrms insulation rating for systems requiring significant potential difference between input and output grounds. Evaluate the 10 Mbps data rate against the system's communication speed requirements.

Logic Output Optoisolators Part Context

This part belongs to the PS9124 series of high-speed optocouplers from Renesas. The series is designed for applications demanding fast switching speeds and high reliability. The PS9124-V-AX variant specifically denotes the version compliant with certain safety certifications, distinguishing it from other variants in the family that may lack specific regulatory approvals.

Logic Output Optoisolators Replacement Considerations

Check for direct substitutes like the PS9124-F3-AX if safety certification differences are acceptable. Verify pinout compatibility before swapping. Ensure the replacement maintains the same 10 Mbps speed and 3750 Vrms isolation rating.
