Short-range fiber optic devices offer significantly higher margin specifications (creepage/clearance) than existing optocouplers and provide superior galvanic isolation compared to transformer-based technology.
Fiber optic technology offers excellent EMI resistance and EMC characteristics. The Avago HFBR-3810Z short-range transceiver/receiver operates reliably in the high-noise environments common in high-voltage switching and motor control equipment and systems. The DC-coupled data link requires no data encoding or digitization circuitry. The fiber optic receiver features a CMOS/TTL output for simplified interface design.
Key features:
• Proven 650 nm fiber optic technology.
• Voltage transient suppression up to 12 kV according to IEC 60664-1, 24.96 mm pin spacing.
• High speed: DC to 10 MBaud.
• DC-coupled receiver with CMOS/TTL output for simplified designs. No data encoding or digitization circuitry required.
• Compact mounting: 13 mm x 33.56 mm footprint. 4.36 cm² board footprint. Unique board insulation.
• Excellent EMI immunity and EMC characteristics.
• Available with metal shielding: HFBR-3810MSZ
. • Wide operating temperature range: -40 °C to +85 °C.
• RoHS compliant.
In addition to the HFBR-3810Z, it offers a wide range of fiber optic transmitters, receivers, and transceivers, as well as gate drivers for power IGBT/MOSFETs, and optocoupler-based isolation products for applications in wind turbines, wind farms, and solar power generation.
