High isolation photodarlington photocoupler Cosmo KPS28320E TLD with gallium arsenide infrared diode
Cosmo KPS2832 Series Photodarlington Photocoupler
The Cosmo KPS2832 series features photodarlington photocouplers designed for high isolation and voltage applications. These devices combine a photodarlington optically coupled to a gallium arsenide infrared-emitting diode within a compact 4-pin SSOP package. They offer a high collector-emitter voltage of 300V and an input-output isolation voltage of 3750 Vrms, making them suitable for various electronic circuits requiring robust isolation. Key advantages include their small, thin package with a 1.27mm pin pitch, Pb-free and RoHS compliance, and MSL class 1 rating. Applications include telephone/telegraph receivers, FAX machines, and hybrid ICs.
