Fairchild Semiconductor, a provider of high-performance mobile and power semiconductor solutions has created the FODM8801, a part of the OptoHiT family of phototransistor optocouplers exhibiting increased temperatures, which employs the company’s own OPTOPLANAR coplanar packaging technology to enable increased sound resistance and consistent isolation at increased operating temperatures.
Industrial applications experience increased temperature and tight spaces normally in motor control, power supplies and consumer applications like adapters and chargers, thereby posing a challenge to designers. Hence, system design engineers require an optocoupler, which will allow more number of design margins with stable parameters in increased temperature environments.
This device is equipped with an infrared light emitting diode optically attached to a phototransistor made of aluminum gallium arsenide (AlGaAs).
The current transfer ratio (CTR) for both non-saturated and saturated operation modes is consistent and switching specifications over the complete operating temperature ranges from -40°C to +125°C. It also provides superior CTR linearity at increased temperatures and functions at a very low input current (IF). The device is enclosed in a compact, mini-flat, 4-pin package of 1.27mm lead pitch, reducing board space with increased design flexibility, thereby reducing the overall system cost. Lead-free environments depend on this device for high isolation voltage. Devices in the OptoHiT series are well suited for various industrial applications.
