Constant current source in SOT353 package

Resistor-equipped PNP transistor with two diodes on one chip in a SOT353 (SC-88A) plastic package. Stabilized output current of between 15 uA and 50 mA by connection of an external resistor between pins 4 and 5.

Features and benefits

  • One chip integrated constant current source

  • Output current setting by use of an external resistor

  • Very small package

  • Reduces component count and board space

  • AEC-Q101 qualified

Applications

  • Automotive applications

  • Generic constant current source

  • Constant current LED driver

  • Active bias control for audio amplifiers

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
