PS9821-1-F3-AX

Logic Output Optoisolators Overview

The PS9821-1-F3-AX is a high-speed optocoupler from the NEPOC series, manufactured by Renesas Electronics Corporation. It features a single channel with an open collector output type and operates within a supply voltage range of 2.7V to 3.6V. The device supports a data rate of 15Mbps and provides an isolation voltage of 2500Vrms. Key electrical parameters include a typical forward voltage of 1.65V, maximum DC forward current of 15mA, and an output current of 25mA per channel. Propagation delay is specified at a maximum of 75ns for both low-to-high and high-to-low transitions, with typical rise and fall times of 20ns and 5ns respectively. The component is housed in an 8-SSOP package.

Logic Output Optoisolators Feature Summary

Logic Output Optoisolators Procurement Notes

Verify the specific suffix F3-AX against the official Renesas datasheet to confirm pinout and packaging dimensions match your PCB footprint. Confirm RoHS compliance status as indicated in the latest product documentation. Check for any recent Product Change Notices (PCN) regarding label or material updates that may affect integration. Ensure the source is an authorized distributor to guarantee authenticity and traceability of the component.

Logic Output Optoisolators Selection Notes

Select this component when a single-channel high-speed isolator with 15Mbps capability is required. It is suitable for designs operating between 2.7V and 3.6V. Consider the 8-SSOP package size for board layout constraints. Verify that the 2500Vrms isolation rating meets the safety standards of the target application. Compare propagation delays if timing precision is critical for the specific digital interface being implemented.

Logic Output Optoisolators Part Context

This part belongs to the NEPOC family of high-speed optocouplers from Renesas. It shares architectural similarities with other models in the series but differs in channel count and specific electrical characteristics.
