OLS2449

Overview

The OLS2449 is a dual-channel, radiation-tolerant phototransistor optocoupler housed in an eight-pin Leadless Chip Carrier (LCC) hermetic package. It consists of an LED and N-P-N silicon phototransistor electrically isolated but optically coupled internally. The device features high BV CEO of 65V minimum and 1500 V DC electrical isolation. Electrical parameters align with JEDEC registered 4N49U standards but offer higher current transfer ratio (CTR) and superior CTR degradation characteristics under radiation exposure.

Feature Summary

Radiation tolerance for gamma, neutron, and proton environments
Hermetic surface mount construction for high reliability
High current transfer ratio at low LED currents
Guaranteed performance over -55 °C to +100 °C ambient temperature range

Applications

High-reliability applications requiring optical isolation in radiation environments
Systems exposed to gamma, neutron, and proton radiation
Applications demanding high CTR and low saturation V CE

Procurement Notes

Verify availability through Skyworks Solutions or authorized distributors as the component may be subject to limited supply or factory special order status. Confirm that the specific lot meets high-reliability screening requirements if applicable. Ensure the hermetic LCC-8 package matches the design constraints. Validate radiation tolerance specifications against the specific mission profile requirements before finalizing procurement.

Selection Notes

Select the OLS2449 when radiation hardness is critical for system integrity. Choose this part over standard optocouplers for environments involving significant ionizing radiation. Consider the hermetic packaging for harsh environmental conditions. Evaluate the higher CTR benefits for low-current LED drive applications. Ensure the 1500 V DC isolation voltage meets the safety requirements of the target circuit design.

Part Context

The OLS2449 belongs to Skyworks Solutions' portfolio of high-reliability optoelectronic components designed for aerospace and defense sectors. It shares processing similarities with the OLS049 but offers enhanced current transfer ratio. The device addresses the need for robust signal isolation in space and military applications where standard semiconductor devices would fail due to radiation-induced degradation.
