6N135, 6N136, CT4502, CT4503
1Mbit/s High Speed Phototransistor Optocoupler
Description
The 6N135, 6N136, CT4502 and CT4503 devices
each consist of an infrared emitting diode, optically
coupled to a high speed photo detector transistor. A
separate connection for the photodiode bias and
output-transistor collector increase the speed by
several orders of magnitude over conventional
phototransistor
couplers
by
reducing
the
Features
High speed 1MBit/s
High isolation voltage between input and output
(Viso=5000 Vrms )
Guaranteed CTR performance from 0°C to 70°C
Wide operating temperature range of -55°C to
100°C
Regulatory Approvals
UL - UL1577 (E364000)
VDE - EN60747-5-5(VDE0884-5)
CQC – GB4943.1, GB8898
IEC60065, IEC60950
base-collector capacitance of the input transistor.
The devices are packaged in an 8-pin DIP package
and also available in gullwing (400mil) and surface
mount lead forming.
Applications
Line receivers
Telecommunication equipment
High speed logic ground isolation
Feedback loop in switch-mode power supplies
Home appliances
