Additional Details

The DTD114EK comes in a compact surface-mount package optimized for high-density mounting. The integrated resistor network eliminates the need for external biasing resistors, simplifying the design process. Key electrical characteristics include a collector-base voltage of -50V, a collector-emitter voltage of -50V, and a collector current of -100mA. The power dissipation is approximately 200mW. The built-in resistor (R1) is 10kΩ, providing a defined base current for a given input voltage. This configuration is advantageous in switching applications where a specific input threshold is required. The operating temperature range extends from -55°C to +150°C. The DTD114EK is designed to minimize the space needed in circuits by incorporating the biasing resistors inside the package, making it easier to assemble, and decreasing the number of parts required. It enhances performance in digital circuits where consistent transistor biasing is critical.
