DESCRIPTION:
The CENTRAL SEMICONDUCTOR CMPP6027R and CMPP6028R 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: CMPP6027R: P27
