Overview
The FOD270LSD is a single-channel photovoltaic output optoisolator manufactured by onsemi. It features an infrared LED coupled to a photovoltaic array, providing high isolation voltage capabilities suitable for robust signal isolation solutions. The device is housed in an 8-pin SOIC surface-mount package, designed for direct connection to logic circuits without requiring external biasing for the output side.
Feature Summary
- Photovoltaic output architecture eliminates the need for external supply voltage on the receiver side
- High isolation voltage rating ensures reliable signal transmission across isolated boundaries
- Surface-mount SOIC packaging facilitates automated assembly and compact board design
Applications
- Solid-state relay driver circuits
- Microcontroller interface isolation
- Industrial control system signal transfer
Procurement Notes
Verify the specific suffix L against official datasheets to confirm lead time and availability constraints. Confirm RoHS compliance status and packaging quantity requirements with the distributor prior to ordering. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when a zero-bias output is required for galvanic isolation. Compare propagation delay and isolation voltage ratings against alternative optocouplers if higher speed or different pin configurations are needed. Validate thermal performance within the target operating temperature range.
Part Context
This part belongs to the FOD series of optoisolators from onsemi, focusing on high-reliability isolation applications. The photovoltaic output type distinguishes it from transistor or logic-gate output variants, offering unique advantages in specific power management and switching topologies.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Generic equivalents may differ in isolation voltage or current transfer ratio. Verify pin compatibility and electrical specifications before substitution.
