Product Brief
CFD4448
120V, 250mA Switching Diode
in ultra miniature SOD-882L package
Central Semiconductor’s CFD4448 is a high speed switching
diode with low reverse leakage ideal for applications where
small size and operational efficiency are prime requirements.
The CFD4448 utilizes 91% less board space than the industry
standard SOD-123 and 58% less than the SOT-523; equally
important is its low profile of 0.4mm.
Features:
• Current (IF = 250mA)
• Forward voltage drop (VF = 0.91V @ 100mA)
• Extremely Fast Switching Speed (4.0ns)
• Low capacitance (2.0pF)
Applications:
• General purpose switching
• Steering diode arrays
• Flyback diodes
• Polarity protection
• Battery powered portable equipment
Benefits:
• Low profile package
• Very low reverse leakage current
• Low capacitance and fast switching
