DATA SHEET OLI249: Radiation-Tolerant, Phototransistor Optocoupler for Hybrid Assembly Features Current transfer ratio (CTR) is: 5 6 4 Cathode Base Emitter Guaranteed over -55 C to +100 C ambient temperature range High at low input current: 200% at IF = 2 mA over temperature Comparable to Darlington output, but with low saturation VCE = 0.15 V typical 1500 VDC electrical isolation Anode Collector 1 3 Small footprint for hybrid device 202467-001 More radiation tolerant than 4N49 (contact Isolink for more information) Figure 1. OLI249 Block Diagram Similar to 4N4X type optocouplers High reliability and rugged construction Custom package is available (contact Isolink for more information) Description The OLI249 is designed especially for hybrid applications that Figure 1 shows the OLI249 functional block diagram. Table 1 require optical isolation with high CTR and low saturation VCE. provides the OLI249 absolute maximum ratings. Table 2 provides Each OLI249 consists of an LED and N-P-N silicon phototransistor the OLI249 electrical specifications. that is mounted and coupled in a miniature custom ceramic Figures 2 through 4 illustrate the OLI249 typical performance package. The low input current makes the OLI249 well suited for characteristics. Figure 5 shows the OLI249 switching test circuit. direct Complementary Metal Oxide Semiconductor (CMOS) to Low Figure 6 provides the OLI249 package dimensions. Power Schottky Transistor-Transistor Logic (LSTTL)/ Transistor- to-Transistor Logic (TTL) interfaces. Electrical parameters are similar to the JEDEC registered 4N49 optocoupler, but with better CTR degradation characteristics due to radiation exposure. Device mounting is achieved by standard hybrid assembly with non-conductive epoxies. Gold or aluminum wire bonding can be used to make electrical connections for maximum placement flexibility. Special electrical parametric selections are available upon request.

There is no damage to the 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 in the above table may result in permanent damage to the device. 2 Measured between pins 1 and 6 shorted together, and pins 2, 3, 4, and 5 shorted together. TA = 25 C and duration = 1 s. 3 Value applies for Pw 1 ms, PRR 300 pps. 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.
