Isocom Limited is a leading Manufacturer of HIgh-Performance IC Optocouplers providing isolation for High-Voltage Power Systems in radiation hard environments with Space, Satelite, High-Performance Military and High-Rel Commercial Infrastructure applications.
Our Ceramic Optocouplers are hermetically sealed and screen processed. Applications include The International Space Station, Galileo, Glonass and the European Fighter Plane.
Isocom manufactures the following Radiation Hard Optocouplers
QC88000-C001 Ceramic Hermetically Sealed Transistor Optocouplers
4N24 CSM1200
4N49 CSM1224
CD500/501 CSM2224
CH300 CSM165-2
CS200/201 CSM165-4
CS224 IS49
CSM200
The Transistor Optocouplers are single, dual and quad, hermetically sealed optocouplers. Each channel is composed of an infra-red emitting diode and a silicon phototransistor. Package styles for these devices include Metal Can T05, 6 pin, 8 pin, 16 pin flat pack and hybrid 4 pin, with surface mount, butt cut and gull wing options available.
QC88000-C002 Ceramic Hermetically Sealed High Speed Optocouplers
4N55 CSM168-4
CD850 CSM1800
CH380 CSM1801
CS800/801 MC800
CSM168-2
The High Speed Optocouplers are single, dual and quad, hermetically sealed optocouplers. Each channel is composed of an infra-red light emitting diode and a photon detector high speed transistor output. Package styles for these devices include Metal Can T05, 6 pin, 8 pin, 16 pin flat pack, 6 pin LCC and hybrid 6 pin, with surface mount, butt cut and gull wing options available. Separate connections for the photodiodes and output transistor collectors improve the speed up to a hundred times that of a conventional phototransistor optocoupler by reducing the base-collector capacitance.
QC88000-C003 Ceramic Hermetically Sealed High Gain Optocouplers
6N140A CS700
CD750 CSM141/A
CD5731 CSM160/161/162-2
CH370 CSM160/161/162-4
CS5700 CSM1700
The High Gain Optocouplers are single, dual and quad, hermetically sealed optocouplers. Each channel contains a light emitting diode which is optically coupled to an integrated high gain photon detector. The high gain output stage features an open collector output providing both lower saturation voltage and higher signalling speed than a conventional Photo-Darlington optocoupler. The supply voltage can be operated as low as 2.0V without adversely affecting the parametric performance. The High Current Transfer Ratio of the optocouplers makes them ideal for low input current, min 0.5mA, applications.
The radiation immunity of the High Gain optocouplers compared to conventional photo transistor optocouplers is due to the shallow depth and small junctions offered by the IC process.
The High Gain optocoupler family is also available in various package styles including Metal Can T05, 6, 8 and 16 pin DIP through hole, 16 pin surface mount DIP flat pack and a 6 Pin leadless ceramic chip carrier. The devices can be purchased with lead bend and plating options.
QC88000-C004 Ceramic Hermetically Sealed High Gain Photon Optocouplers
6N134 CSM169-2
CD650/651 CSM169-4
CH350 CSM1600
CS600 MC600
The High Gain Photon Optocouplers are single, dual and quad, hermetically sealed optocouplers. Each channel contains a light emitting diode which is optically coupled to an integrated high speed photon detector. The output of the detector is an open collector Schottky clamped transistor. Internal shields provide a guaranteed common mode transient immunity specification of 1000 V/µs. These optocouplers are for Isolation Voltage applications requiring up to 2500 Vdc.
The High Gain Photon optocoupler family is also available in various package styles including Metal Can T05, 6, 8 and 16 pin DIP through hole, 16 pin surface mount DIP flat pack and a 6 Pin leadless ceramic chip carrier. The devices can be purchased with lead bend and plating options.
