Overview
The OLS249SXV is a radiation-tolerant phototransistor optocoupler manufactured by Skyworks Solutions Inc. It consists of an LED optically coupled to an NPN silicon phototransistor, housed in a hermetic surface-mount leaded chip carrier (LCC) package. The device provides 1500 VDC electrical isolation and features high current transfer ratio (CTR) with superior degradation characteristics under radiation exposure compared to standard JEDEC registered devices like the 4N49.
Feature Summary
- Radiation tolerant design for harsh environments
- Hermetic surface-mount LCC packaging
- High current transfer ratio stability
- 1500 VDC electrical isolation
Applications
- Avionics systems
- Military communications
- Space applications
- Radar systems
- Medical monitoring equipment
Procurement Notes
Verify the specific suffix 'SXV' against official Skyworks documentation to confirm exact binning or screening levels. Ensure compatibility with existing hermetic LCC footprints. Confirm radiation tolerance specifications match mission requirements. Check for availability of test reports regarding CTR degradation under ionizing radiation.
Selection Notes
Select this component when radiation hardness is critical. Compare CTR performance against standard optocouplers. Verify input current requirements for direct CMOS or TTL interfacing. Ensure the hermetic seal meets environmental sealing standards. Consider package size constraints for compact avionics designs.
Part Context
Part of the Skyworks radiation-tolerant optocoupler family. Designed as a robust alternative to non-radiation-hardened equivalents. Offers improved reliability in aerospace and defense sectors where standard semiconductors may fail due to total ionizing dose effects.

FAQ
What is the electrical isolation voltage?
The device provides 1500 VDC electrical isolation between the input LED and output phototransistor.
How does it compare to the 4N49?
It offers similar electrical parameters but with significantly better current transfer ratio degradation characteristics under radiation exposure.
What type of interface does it support?
The low input current allows direct interfacing with CMOS and low-power Schottky transistor-transistor logic (LSTTL/TTL).
