PS9115-F3-AX

Logic Output Optoisolators Overview

The PS9115-F3-AX is a high-speed logic output optoisolator manufactured by CEL. It features a push-pull totem pole output stage capable of data rates up to 10Mbps. The device provides 3750Vrms isolation voltage and exhibits a common-mode transient immunity (CMTI) of 10kV/µs. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum DC forward current of 30mA. The component is housed in a 5-SO package with a width of 4.40mm and functions reliably across an operating temperature range of -40°C to 85°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix AX against official datasheets to confirm packaging and tape-and-reel specifications. Confirm end-of-life status as this part may be discontinued. Ensure compatibility with existing PCB footprints for the 5-SO package. Cross-reference CMTI ratings with system noise requirements. Validate operating temperature ranges against environmental conditions.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 10Mbps data rate limit for signal integrity. Evaluate the 3750Vrms isolation barrier for safety compliance in high-voltage environments.

Logic Output Optoisolators Part Context

This device belongs to the NEPOC series from CEL, now part of Renesas Electronics. It represents a specialized solution for high-speed isolated communication where traditional transistor outputs are too slow. The 5-SO form factor allows for compact surface-mount integration in dense electronic assemblies requiring galvanic separation.

Logic Output Optoisolators Replacement Considerations

Check for direct pin-compatible substitutes within the same NEPOC family. Verify that alternative devices maintain the 10Mbps speed and 10kV/µs CMTI specifications. Ensure replacement parts support the same 5-SO package dimensions and voltage ratings.
