Additional Details

The DTA114EKAFRAT46 is housed in a small surface mount package, making it suitable for high-density circuit designs. Its integrated bias resistors eliminate the need for external resistors, further minimizing board space. The transistor is designed for general-purpose switching applications and is commonly used in digital circuits, inverters, and LED drivers. The input resistor value (R1) is 10 kΩ, and the resistor between base and power supply (R2) is also 10 kΩ. The output current is rated at a maximum of 100mA. The supply voltage is typically 50V. The operating temperature range is typically -55°C to +150°C.

Using this digital transistor in applications will simplify the BOM, improve board density, and potentially lower total costs.
