OLS2249

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 phototransistor 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). Figure 1.
