DATA SHEET
OLS449: Radiation-Tolerant Phototransistor Hermetic
Surface-Mount Optocoupler
Features
Radiation tolerant version of the 4N49U
High current transfer ratio (CTR) is guaranteed:
– Over –55 °C to +125 °C ambient temperature range
– At LED current of 1mA
1000 V
DC electrical isolation
Same reliable processing and construction as the OLS249, but
with a higher CTR
High-reliability screenings are available
Description
The OLS449 is specifically designed for high reliability and space
applications that require optical isolation in radiation
environments such as gamma, neutron, and proton radiation with
a high CTR and low saturation V
CE. Each optocoupler consists of
an LED and N-P-N silicon phototransistor that is electrically
isolated, but optically coupled inside a hermetic six-pin Leadless
Chip Carrier (LCC) package.
Electrical parameters are similar to the JEDEC registered 4N49
optocoupler, but with a higher CTR and better CTR degradation
characteristics due to radiation exposure.
The OLS449 is designed for a low LED operating current while
providing excellent radiation tolerance margins. The OLS449 has
100 percent high-reliability screenings available.

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters
set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.

ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.
