Technical Specifications

The DTB743ZE transistor has the following key technical specifications:

• Transistor Type: PNP
• Built-in Resistors: R1 = 4.7 kΩ, R2 = 47 kΩ
• Collector-Emitter Voltage (VCEO): -50 V
• Collector Current (IC): -500 mA
• Power Dissipation (PD): 200 mW
• Operating Temperature Range: -55°C to +150°C
• Package: SOT-346

The integration of bias resistors (R1 and R2) allows for easier implementation of switching and amplification circuits. The defined resistor values provide a stable bias point, making the DTB743ZE suitable for a wide range of applications. Its small SOT-346 package makes it well-suited for applications where board space is limited. The device's ability to handle a collector current of up to -500mA makes it suitable for driving larger loads.
