SAN JOSE, Calif. – November 21, 2011 – Industrial applications present reliability challenges to designers as a result of the high temperature and tight spaces commonly found in power supplies, motor controls and consumer applications such as chargers and adapters. To combat these reliability challenges, system design engineers need an optocoupler, which allows for more design margins and has stable parameters in high temperature environments.

To meet this need, Fairchild Semiconductor (NYSE: FCS), a leading global supplier of high-performance power and mobile semiconductor solutions, developed the FODM8801, part of the OptoHiT™ series of high temperature phototransistor optocouplers. These devices use Fairchild's proprietary OPTOPLANAR® coplanar packaging technology to achieve high noise immunity and reliable isolation at high operating temperatures.

The FODM8801 consists of an aluminum gallium arsenide (AlGaAs) infrared light emitting diode optically coupled to a phototransistor. The device provides a guaranteed Current Transfer Ratio (CTR) for both saturated and non-saturated modes of operation and switching specifications over the extended operating temperature range (-40°C to +125°C) for greater design flexibility.

The device offers excellent CTR linearity at high temperature and operates at a very low input current (IF). The FODM8801 is packaged in a compact, half-pitch, mini-flat, 4-pin package (1.27mm lead pitch), saving board space and providing more design flexibility, allowing for overall reductions in system cost.

Additionally, the FODM8801 provides high isolation voltage for increased reliability in lead-free environments. Devices in the OptoHiT series are ideally suited for industrial applications, including power supplies, motor controls and consumer applications, which include chargers and adapters.

The FODM8801 is part of Fairchild's comprehensive portfolio of high performance optocouplers that offer leading-edge noise immunity resulting from its proprietary OPTOPLANAR coplanar packaging technology. The OPTOPLANAR technology ensures safe insulation thickness of more than 0.4 millimeters in attaining reliable high voltage isolation, and provides >5mm creepage and clearance distance, certified by UL1577 and DIN_EN/IEC60747-5-2 standards.
