General Descriptions
• DDC144NS features discrete dual NPN transistors that
can support continuous maximum current up to 100 mA.
It is suited for applications where the load needs to be
turned on and off using circuits like micro-controllers,
comparators, etc., particularly at a point of load. The
component devices can be used as a part of a circuit or
as a stand alone discrete device.
Features
• Epitaxial Planar Die Construction
• Ideally Suited for Automated Assembly Processes
• Lead Free By Design/RoHS Compliant (Note 1)
• "Green" Device (Note 2)
Mechanical Data
• Case: SOT-363
• Case Material: Molded Plastic. "Green” Molding
Compound. UL Flammability Classification Rating 94V-0
• Moisture Sensitivity: Level 1 per J-STD-020C
• Terminal Connections: See Figure 2
• Terminals: Finish - Matte Tin annealed over Alloy 42
leadframe. Solderable per MIL-STD-202, Method 208
• Marking Information: See Page 3
• Ordering Information: See Page 3
• Weight: 0.0065 grams (approximate)
