The DTC115EEGZTL is a digital transistor (Bias Resistor Transistor - BRT) manufactured by Rohm Semiconductor. It is an NPN transistor with built-in resistors. This integration simplifies circuit design, minimizes the number of components required, and saves board space. It is specifically designed for switching applications where a controlled input current dictates the output. The internal resistors provide a bias network, removing the necessity for external biasing resistors.

Applications

• Digital circuit switching
• Inverter circuits
• Driver circuits
• Load switches
• General-purpose switching

Features

• Built-in bias resistors (R1 = 100kΩ, R2 = Open)
• NPN Transistor
• Low input current
• Surface Mount Device (SMD) package
• Halogen-free

Benefits

• Reduced component count
• Simplified circuit design
• Lower assembly costs
• Minimized board space
• Improved circuit performance

The DTC115EEGZTL provides a simplified solution for various switching needs. The integrated resistors guarantee a stable bias point, eliminating the necessity for manual resistor selection. The surface mount package is designed for high-density mounting on printed circuit boards. This transistor has low input current requirements, making it suitable for battery-operated devices. The 'EE' in the part number refers to specific resistor values. R1 is 100kΩ, and R2 is not present (open). This creates a specific bias arrangement that dictates switching performance.
