3C91C Datasheet | TT Electronics

Features : - TO-72 hermetically sealed package - 1 k VDC 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) IF (m A) Min / Max Typ / Max VCE (V) Typ / Max Lead Length 935 nm 0.3 / 2.0 10 / 50 10 / 50 Transistor 880 nm 0.15 / NA 0.3 / NA 0.6 / NA 1.0 / 5.0 3 / 40 1 / 40 0.50" 10 / 30 5 /...
