4N25-X隔離器的光隔離器-晶體管光電輸出規(guī)格書(shū)PDF中文資料

DESCRIPTION

The 4N25 family is an Industry Standard Single Channel

Phototransistor Coupler. This family includes the 4N25, 4N26,

4N27, 4N28. Each optocoupler consists of gallium arsenide

infrared LED and a silicon NPN phototransistor.

These couplers are Underwriters Laboratories (UL) listed to

comply with a 5300 VRMS isolation test voltage. This isolation

performance is accomplished through special Vishay

manufacturing process.

Compliance to DIN EN 60747-5-2 (VDE 0884)/

DIN EN 60747-5-5 pending partial discharge isolation

specification is available by ordering option 1.

These isolation processes and the Vishay ISO9001 quality

program results in the highest isolation performance available

for a commercial plastic phototransistor optocoupler.

The devices are also available in lead formed configuration

suitable for surface mounting and are available either on tape

and reel, or in standard tube shipping containers.
