Nexperia NCR32xZ NPN Low Side LED Drivers

Nexperia NCR32xZ NPN Low Side LED Drivers consist of a resistor-equipped NPN transistor with two diodes on one chip in a medium-power SOT223 (SC-73) SMD plastic package. These LED drivers have stabilized output current of 10mA that can be adjustable up to 250mA when an external resistor is used. The Nexperia NCR32xZ LED drivers feature high power dissipation, low voltage overhead of 1.4V, and high-current accuracy at a supply voltage variation. These drivers are ideal for interior lighting, dashboard, and instrumentation.

Features

  • Stabilized output current of 10mA without external resistor
  • Stabilized output current adjustable up to 250mA when an external resistor is used
  • High current accuracy at supply voltage variation
  • Low voltage overhead of 1.4V
