CMPP6027

CMPP6028

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

(IV), Peak Current (IP), and Intrinsic Standoff Ratio (η).

MARKING CODES: CMPP6027: P27

CMPP6028: P28

NOTE: Reverse Lead Codes Available, Add “R” to

the end of the Part #.
