SURFACE MOUNT

ULTRA HIGH SPEED

SILICON SWITCHING DIODE

DESCRIPTION:

The CENTRAL SEMICONDUCTOR CFD4448

is an ultra high speed switching diode ideal for

applications where very small size and operational

efficiency are prime requirements.

MARKING CODE: X

FEATURES:

• Current (IO=250mA)

• Forward Voltage Drop (VF=0.91V TYP @ 100mA)

• Extremely Fast Switching Speed (4ns Max)

• Small TLP, 1.0 x 0.6 x 0.4mm, Ultra Low Profile

Leadless Surface Mount Package.

APPLICATIONS:

• General Purpose Switching

• DC - DC Converters

• Flyback Diodes

• Polarity Protection

• Battery powered applications including

Cell Phones, Digital Cameras, Pagers,

PDAs, Laptop Computers, etc.

MAXIMUM RATINGS: (TA=25°C)
