CMLT5088EM TR PBFREE

Overview

The CMLT5088EM is a surface-mount silicon dual matched NPN transistor from Central Semiconductor Corp. It integrates two individual, isolated transistors with matched VBE(ON) characteristics in a SOT-563 package. Key electrical parameters include a collector-base voltage of 50V, continuous collector current of 100mA, and power dissipation of 350mW at 25°C. The device features a typical DC current gain (hFE) ranging from 300 to 900 at low currents, a transition frequency (fT) of 100MHz, and a noise figure of 3.0dB. Matching characteristics ensure |VBE1-VBE2| differences remain within 10mV across specified current ranges.
