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 photo
transistors. 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.
FEATURES
Ultra small and thin package
(12-pin ultra shrink SOP, Pin pitch 0.8 mm, 4.4 (L) 5.6 (W) 2.5 (H))
Common lead PS2841-4A: cathode, collector common
PS2841-4B: anode, collector common
High current transfer ratio (CTR = 200% TYP. @ IF = 1mA)
High isolation voltage (BV = 1 500 Vr.m.s.)
