4N25(G)V/ 4N35(G)V Series
Vishay Telefunken
Optocoupler with Phototransistor Output
Description
The 4N25(G)V/ 4N35(G)V series consists of a photo-
transistor optically coupled to a gallium arsenide
infrared-emitting diode in a 6-lead plastic dual inline
package.
The elements are mounted on one leadframe using
a coplanar technique, providing a fixed distance
between input and output for highest safety
requirements.
Applications
Circuits for safe protective separation against
electrical shock according to safety class II
(reinforced isolation):
D For appl. class I – IV at mains voltage ≤ 300 V
D For appl. class I – III at mains voltage ≤ 600 V
according to VDE 0884, table 2, suitable for:
Switch-mode power supplies, line receiver,
computer peripheral interface, microprocessor
system interface.
VDE Standards
These couplers perform safety functions according
to the following equipment standards:
D VDE 0884
Optocoupler for electrical safety requirements
D IEC 950/EN 60950
Office machines (applied for reinforced isolation
for mains voltage ≤ 400 VRMS)
D VDE 0804
Telecommunication apparatus and data
processing
D IEC 65
Safety for mains-operated electronic and related
household apparatus
