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
