SURFACE MOUNT SILICON

PROGRAMMABLE UNIJUNCTION

TRANSISTORS

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).
