DATA SHEET
OLS2249: Dual Channel, Radiation Tolerant, Photo-Transistor
Hermetic Surface Mount Optocoupler
Features
Dual channels of OLS049/OLS249
CTR guaranteed over 55 °C to +100 °C ambient temperature
range
1500 VDC electrical isolation
Radiation tolerant
High-reliability screening is available
Description
The OLS2249 is specifically designed for high-reliability
applications that require optical isolation in radiation
environments such as gamma, neutron, and proton radiation with
high Current Transfer Ratio (CTR) and low saturation VCE. Each
optocoupler channel consists of an LED and N-P-N silicon photo-
transistor that is electrically isolated, but optically coupled inside
a hermetic eight-pin Leadless Chip Carrier (LCC) package.
The OLS2249 has 100 percent high-reliability screening parts
available (contact Isolink for more information).
