SURFACE MOUNT SILICON
PROGRAMMABLE UNIJUNCTION
TRANSISTOR
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
(I ), Peak Current (I ), and Intrinsic Standoff Ratio (η).
