OptoHiT™ Optocoupler High Temperature

FODM8801 OptoHiTTM 125ºC Phototransistor The OptoHiT™ trademark denotes Optocoupler High Temperature, utilizes Fairchild’s leading edge patented process technology to achieving high operating temperature characteristics, up to 125°C. The first optocoupler in OptoHiT™ Series, FODM8801, consists of an aluminum gallium arsenide (AlGaAs) infrared light emitting diode optically coupled to a phototransistor, in a compact half pitch, mini-flat, 4-pin package. It set various benchmarks in guaranteeing Current Transfer Ratio (CTR) and switching performance across extended operating temperature range.

Value Propositions of OptoHiTTM Optocouplers High efficiency emitter and tight hfe binning of transistor result in Guaranteed Current Transfer Ratio (CTR) specifications across full temperature range from -40ºC to +125ºC Excellent CTR linearity at high temperature CTR at very low input current, IF (1mA, 1.6mA, and 3mA) Guaranteed switching specifications over extended operating temperature range as compared to the existing optocouplers Owing to its small footprint, this half-pitch Mini-Flat Package (MFP) can further save on board real estate giving hardware designers more flexibility and allowing for overall systems cost savings High isolation voltage certified by UL1577 (3,750VACRMS for 1 min.) and DIN_EN/IEC60747-5-2(VDE) certification for increased reliability 245°C IR reflow soldering capability in lead free environments

OPTOPLANAR® Technology The High-Speed and Gate Drive optocoupler families utilize Fairchild’s patented coplanar packaging technology, Optoplanar® technology, and optimized IC design to guarantee minimum 20kV/μs Common Mode Rejection (CMR). Competitive Advantages High Common Mode Noise Rejection (CMR). This construction eliminates the capacitive charge buildup that occurs in the over-under construction. Fixed isolation gap (thickness through insulation). So a consistent high input to output isolation voltage The High-Speed and Gate Drive series are packaged in Fairchild’s patented coplanar packaging technology called Optoplanar®, and using optimized IC design to guarantee 20kV/µs minimum Common Mode Noise Rejection rating. This co-planar packaging eliminates the capacitive charge buildup, and thus reduces package capacitance by more than 30% compared to competitive solutions, which uses the over-under construction. In addition the fixed isolation gap, as defined by the thickness through insulation, provide a consistently high input to output isolation voltage. These competitive advantages will further differentiate us from our competitors, especially when used in noisy industrial environments. Positioned as high CMR, provides a credible edge over competitive alternatives; high CMR is a consistent value-added message from Product Line to the field and end customers.
