PS9309L2-AX

Logic Output Optoisolators Overview

The PS9309L2-AX is a high-speed logic output optocoupler manufactured by Renesas Electronics Corporation. It features a single channel with a totem pole (active high) output configuration, designed for applications requiring fast signal transmission and electrical isolation. The device provides an insulation voltage of 5000Vrms and exhibits a common-mode transient immunity of 15kV/µs. Key timing parameters include a propagation delay of 200ns maximum, a rise time of 24ns, and a fall time of 3.2ns. It operates within a supply voltage range of 4.5V to 20V and supports a maximum continuous output current of 25mA. The component is housed in a 6-pin SDIP gull-wing package.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'AX' against the manufacturer's latest datasheet to confirm pinout and packaging details. Check for end-of-life status or recommended new designations, as some variants may be obsolete. Ensure compatibility with your system's voltage levels and thermal requirements before finalizing procurement. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Logic Output Optoisolators Selection Notes

Select this component when high-speed isolation is critical for gate driving or signal interfacing. The low propagation delay and fast switching characteristics make it suitable for high-frequency applications. Consider the 5000Vrms isolation rating for safety-critical designs. Evaluate the 25mA output current capability against the load requirements of the driven device. The SDIP package offers a compact solution for space-constrained PCB layouts.
