PHOTOCOUPLER

PS2841-4A,PS2841-4B

WORLD’S SMALLEST CLASS, FOUR CHANNELS

12-PIN ULTRA SHRINK SOP PHOTOCOUPLER

DESCRIPTION

The PS2841-4A and PS2841-4B are optically coupled isolators containing GaAs light emitting diodes and NPN

silicon phototransistors.

These products include four channels in a single package for high-density mounting applications.

The PS2841-4A and PS2841-4B are the world's smallest class of photocouplers and realize about 50% reduction in

mounting area compared with the PS280x and PS281x Series.

*1 The optically induced leakage current is current which can be measured at transistor if LED = ”ON” and LED =

”OFF”.

LED of channel 1 is switched to ”ON”.

At Tr-output of channel 2 a voltage is applied and one can measure a current between emitter and collector.

This is leakage current (at I
