DATA SHEET OLS2249: Dual-Channel, Radiation-Tolerant Phototransistor 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. OLS2249 Block Diagram Figure 1 shows the OLS2249 functional block diagram. Table 1 provides the OLS2249 absolute maximum ratings. Table 2 provides the OLS2249 electrical specifications. Figures 2 through 4 illustrate the OLS2249 typical performance characteristics. Figure 5 shows the OLS2249 switching test circuit. Figure 6 provides the OLS2249 package dimensions.

Table 1. OLS2249 Absolute Maximum Ratings1 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. ■ Measured between pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7, and 8 shorted together.
