Dual Pair, Common Cathode Low VF Schottky Diodes
CMLSH2-4LC
40V, 200mA
|
|
The CMLSH2-4LC is a dual pair of low VF Schottky diodes packaged in the space saving SOT-563 surface mount case. This device has two isolated pairs of 40V, 200mA Schottky diodes in a common cathode configuration making it one of the world’s smallest discrete dual diode pair device. The CMLSH2-4LC has a typical low VF of 0.24V and a typical switching speed of 3.5ns and is ideal for a wide range of portable battery powered circuit applications.
The CMLSH2-4LC in the six lead SOT-563 case with a maximum height of 0.6mm has a 45% lower profile than its predecessor the SOT-363 (1.1mm) and utilizes 42% less board space. This device is an ideal choice for small electronic products, including: cell/smart phones, MP3 music players, medical test equipment, bar code scanners, PDAs, and notebook computers.
The CMLSH1-40 is available 3,000 pcs on 7” tape & reel. Sample devices are available upon request.
