DESCRIPTION
The SFH6345 is an optocoupler with a GaAlAs infrared
emitting diode, optically coupled to an integrated photo
detector consisting of a photo diode and a high speed
transistor in a DIP-8 plastic package. The device is similar to
the 6N135 but has an additional Faraday shield on the
detector which enhances the input-output dV/dt immunity.
Signals can be transmitted between two electrically
separated circuits up to frequencies of 2 MHz. This an ideal
solution for industrial communication bus isolation, as well
as isolated drive circuit applications such as IPM (intelligent
power module) drivers.
FEATURES
• High-speed optocoupler without base
connection
• Isolation test voltage: 5300 VRMS
• GaAlAs emitter
• Integrated detector with photo diode and
transistor
• High data transmission rate: 1 MBit/s
• TTL compatible
• Open collector output
• Good CTR linearity relative to forward current
• Field effect stable
• Low coupling capacitance
• Very high common mode transient immunity dV/dt:
15 kV/μs at VCM = 1500 V
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• Data communications
• IGBT drivers
• Programmable controllers
• IPM (intelligent power module) drivers
AGENCY APPROVALS
• UL1577 file no. E52744, double protection
• DIN EN 60747-5-5 (VDE0884-5) available with option 1
• cUL components acceptance service no. 5A
• CQC GB8898-2001, GB4943.1-2011
