H11N1SD

Logic Output Optoisolators Overview

The onsemi H11N1SD is a discontinued single-channel logic output optocoupler featuring an open-collector NPN transistor output. It provides 7500Vrms isolation voltage and supports data rates up to 5MHz. Key electrical parameters include a maximum forward current of 3.2mA, typical forward voltage of 1.4V, and output current capability of 50mA. Propagation delays are specified at 330ns maximum for both low-to-high and high-to-low transitions. The device is housed in a 6-SMD鸥翼 (gull-wing) surface-mount package.

Logic Output Optoisolators Procurement Notes

Verify component obsolescence status as the H11N1SD is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure replacement parts meet identical pinout and electrical specifications. Check RoHS compliance requirements against project standards. Validate supplier authenticity to prevent counterfeit components.

Logic Output Optoisolators Selection Notes

Select this component only if legacy compatibility with existing designs is required. Consider alternative active parts from the same family for new projects. Verify package dimensions match PCB footprint constraints. Ensure isolation voltage ratings exceed system operating requirements. Evaluate propagation delay limits against signal timing specifications.

Logic Output Optoisolators Part Context

The H11N1SD belongs to the H11N series of high-speed optocouplers manufactured by onsemi. This series is designed for applications requiring reliable signal transmission across isolated boundaries. The specific SD suffix indicates a surface-mount gull-wing package variant within the broader product line.

Logic Output Optoisolators Replacement Considerations

The H11N1SM is identified as a direct substitute part number available from onsemi. Verify pin compatibility and electrical parameter equivalence before implementation.
