WORLD’S SMALLEST CLASS, FOUR CHANNELS 12-PIN ULTRA SHRINK SOP PHOTOCOUPLER
DESCRIPTION
The PS2845-4A is an optically coupled isolator containing GaAs light emitting diodes and NPN silicon
phototransistors.
This product includes four channels in a single package for high-density mounting applications.
The PS2845-4A is the world's smallest class of photocouplers and realizes 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 anode, cathode, collector common
• High current transfer ratio (CTR = 200% TYP. @ IF = ±1mA)
• High isolation voltage (BV = 1 500 Vr.m.s.)
• Pb-Free product
• Ordering number of tape product: PS2845-4A-F3: 2 500 pcs/reel
• Safety standards
• UL approved: UL1577, Single protecion
