Hi-Reliability Optically Coupled Isolator 3C91C, 3C92C (TX), 3N243, 3N244, 3N245 (TX), 3N262 Features: • TO-72 hermetically sealed package • 1 kVDC electrical isolation • High current transfer ratio • TX devices processed to MIL-PRF-19500 Description: Each device is a high reliability optically coupled isolator that consists of an infrared emitting diode and a NPN silicon phototransistor which are mounted in a hermetically sealed TO-72 package. The 3C91C and 3C92C have a 935 nm wavelength, whereas the 3N243, 3N244, 3N245 and 3N262 have an 880 nm wavelength. All devices have 0.50” (12.70 mm) leads. Electrical characteristics vary. TX devices are processed to OPTEK’s military screening program patterned after MIL-PRF-19500. Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data. Contact your local representative or OPTEK for more information. Applications: • High-voltage isolation between input and output • Electrical isolation in dirty environments • Industrial equipment • Medical equipment • Office equipment Part Number 3C91C 3C92C (TX) 3N243 3N244 3N245 (TX) 3N262 LED Peak Wavelength Sensor Isolation Voltage (,000) CTR IF (mA) Min / Max Typ / Max VCE (V) Typ / Max Lead Length 935 nm 0.3 / 2.0 10 / 50 10 / 50 Transistor 1 880 nm 0.15 / NA 0.3 / NA 0.6 / NA 1.0 / 5.0 3 / 40 1 / 40 0.50" 10 / 30 5 / 30 3C91 1 2 3C92 1 3 4 3 Phototransistor Collector is connected to the Header-Base-Case for ALL versions 3N2XX 2 3 4 2 Pin # 1 2 3 4 3C91 Cathode Collector Emitter Anode 3C92 Cathode Emitter Collector Anode 4 1 3N2XX Emitter Cathode Collector Anode General Note TT Electronics reserves the right to make changes in product specification without notice or liability.
