HFBR-3810Z & HFBR-3810MSZ
650 nm Fiber Optics Link for DC to 10Mbaud
Data Sheet
Description
HFBR-3810Z consists of an optic transmitter and receiver
operating at 650nm wavelength. The pin to pin air gap
distance of 25.1mm provides transient voltage suppres-
sion of 12kV.
Features
Data transmission at signal rates of DC to 10MBaud
DC coupled receiver with CMOS/TTL output for easy
designs: no data encoding or digitizing circuitry
required
High noise immunity
RoHS compliant
Transient voltage suppression of up to 12kV according
IEC 60664-1
Laser class 1 according to IEC-60825: Amendment 2001
Applications
Drives/Inverters
Galvanic isolation on one single PCB
