PS9351L-AX

Logic Output Optoisolators Overview

The PS9351L-AX is a high-speed optocoupler manufactured by Renesas Electronics Corporation. It features a single channel with a data rate of 15 Mbps and an isolation voltage of 5000 Vrms. The device utilizes a push-pull output type and operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum DC forward current of 25mA, a typical forward voltage of 1.56V, and a propagation delay of 60ns for both tpLH and tpHL. The component supports a minimum common-mode transient immunity of 15kV/µs and functions within an operating temperature range of -40°C to 100°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., L2, E3) against the required package and compliance specifications, as variations exist within the PS9351 family. Confirm surface-mount compatibility with the SDIP-6 gull wing package. Ensure the selected variant meets the necessary RoHS and REACH regulatory standards for the target market. Cross-reference datasheet revisions to confirm pinout consistency before integration.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Verify that the input current requirements align with the driving source capabilities. Consider the thermal performance and power dissipation limits if operating near the upper temperature boundary.

Logic Output Optoisolators Part Context

This part belongs to the NEPOC series of high-speed photocouplers from Renesas. It is designed for applications demanding fast signal transfer across isolation barriers. The family typically includes variants with different packaging options and compliance markings. The PS9351L-AX specifically denotes the base model configuration within this high-performance isolation segment.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other 15 Mbps push-pull output optocouplers with similar isolation ratings. Verify pin-to-pin compatibility with packages such as SOIC-6 or SDIP-6. Check equivalent propagation delays and CMTI values to ensure system timing integrity is maintained during replacement.
