QS5U16
Transistors
Small switching (30V, 2.0A)
QS5U16
Features 1) The QS5U16 combines Nch MOSFET with a Schottky barrier diode in a single TSMT5 package. 2) Nch MOSFET have a low on-state resistance with a fast switching. 3) Nch MOSFET is reacted a low voltage drive (2.5V). 4) The Independently connected Schottky barrier diode have a low forward voltage.
