Features

• Built-in bias resistors (R1 = 47 kΩ, R2 = 47 kΩ)
• NPN Transistor
• Reduces component count
• Simplified circuit design
• Halogen-free
• ROHS compliant
• Small SOT-346 package

Benefits

• Reduces overall system cost by eliminating external resistors.
• Saves valuable PCB space, allowing for smaller and more compact designs.
• Simplifies the design process, reducing design time and effort.

Additional Details

The DTC144WU is a NPN digital transistor with built-in bias resistors. Its collector-emitter voltage (VCEO) rating is 50V and it can handle a collector current (IC) of up to 100mA. Power dissipation is 200mW. The built-in resistors (47kΩ) make it easy to implement common-emitter amplifier stages and switching circuits with minimal external components. The SOT-346 package makes it suitable for high-density surface mount assembly.
