High temperature optocoupler series minimizes system failure
November 22, 2011 // Paul Buckley
Fairchild Semiconductor has developed the FODM8801, part of the OptoHiT series of high temperature phototransistor optocouplers. The 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 to +125°C) for greater design flexibility.
The device claim to offer 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 (1.27 mm 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 mm in attaining reliable high voltage isolation, and provides >5 mm creepage and clearance distance, certified by UL1577 and DIN_EN/IEC60747-5-2 standards.
