The DTA114EUA FRAT106 is a digital transistor (also known as a bias resistor transistor or BRT) manufactured by Rohm Semiconductor. This device integrates a transistor with built-in resistors, simplifying circuit design and reducing the number of external components needed. It's commonly used in various electronic applications where space and component count are critical.

Applications:

• Digital circuits
• Switching circuits
• Inverter circuits
• Driver circuits for LEDs, relays, and small loads
• General-purpose amplification

Features:

• Built-in bias resistors: R1 = 10 kΩ, R2 = 10 kΩ (These values can vary slightly depending on the exact specification, but 10kΩ is typical)
• NPN transistor configuration
• Reduces component count and board space
• Simplifies circuit design
• Available in a small surface-mount package (typically SOT-323 or similar)

Benefits:

• Lower component cost due to integrated resistors
• Reduced assembly costs
• Improved circuit reliability
• Simplified PCB layout
• Smaller overall circuit size

Additional Details:

The DTA114EUA's built-in resistors eliminate the need for external biasing resistors, which saves space and simplifies circuit design. The input resistor (R1) is connected between the base and the input terminal, while the base-emitter resistor (R2) provides a stable bias voltage. The transistor is switched on when a sufficient voltage is applied to the input terminal. The device is commonly housed in a small surface mount package, facilitating high-density board designs.

Technical Specifications (Typical):

• Polarity: NPN
