DESCRIPTION:
The CENTRAL SEMICONDUCTOR CMPP6027 and CMPP6028 are silicon programmable unijunction transistors, manufactured in a surface mount SOT-23 package, designed for adjustable (programmable) characteristics such as, valley current (IV), peak current (IP), and intrinsic standoff ratio (η).

MARKING CODES: CMPP6027: P27
