The DTC143ZU is a resistor-equipped NPN transistor manufactured by Rohm Semiconductor. This device integrates bias resistors, simplifying circuit design and reducing the number of external components required. This is particularly useful in applications where space and component count are critical factors.

Applications

• Switching circuits
• Inverter circuits
• Digital logic control
• Load driver circuits
• General-purpose amplification

Features

• Built-in bias resistors (R1 = 4.7 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.
• Improves circuit reliability due to fewer solder joints.
• Environmentally friendly due to halogen-free construction and RoHS compliance.

Additional Details

The DTC143ZU 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 (4.7kΩ and 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.
