The CPC5603 is an N-channel, depletion mode Field

Effect Transistor (FET) that utilizes Clare’s proprietary

third-generation vertical DMOS process. The third

generation process realizes world class, high voltage

MOSFET performance in an economical silicon gate

process. The vertical DMOS process yields a highly

reliable device particularly in difficult application

environments such as telecommunications, security,

and power supplies.

One of the primary applications for the CPC5603 is

as a linear regulator/hook switch for the LITELINK™

family of Data Access Arrangements (DAA) Devices

CPC5620A, CPC5621A, and CPC5622A.

The CPC5603 has a typical on-resistance of 8

, a

drain-to-source voltage of 415V and is available in

the SOT-223 package. As with all MOS devices, the

FET structure prevents thermal runaway and

thermal-induced secondary breakdown.
