Bare Die Product Detail: 1N4448

Switching:
General purpose high conductance fast diode in bare die form suiting small-size and high integration switching applications such as micro SMPS, high frequency DC/DC converters and also free wheeling or polarity protection.
Replaces Motorola (MOT), Fairchild (FSC/FCH), Sprague / Allegro or National (NSC) 1N4448. Metalized with Aluminium top side for wirebonding and Gold back side for solder attach for use in high integration and high reliability applications.
Features:
  • Very small form factor
  • High temperature capability with no package limitation
  • Low capacitance
  • Higher current capability
  • Very low conduction losses
  • Negligible switching losses
  • Low forward voltage drop
