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.

Notes:
*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 IF = 5 mA, VCEO = 24 V). Measurement circuits for optical leakage current E.g. : In the case of 1 to 2-ch (PS2841-4A)
