Additional Details

The DTA144EEFRATL has a collector-emitter voltage (VCEO) of -50V, a collector current (IC) of -100mA, and a power dissipation of 200mW. The DC current gain (hFE) is typically around 68 at IC = -5mA. It is housed in a small SOT-23 (or equivalent) surface mount package, making it ideal for compact electronic devices. The internal resistors ensure stable switching behavior and eliminate the need for external biasing components.

This transistor is designed for general purpose amplification and switching applications where a low input current and a controlled output current are required. The integrated resistors provide a defined bias, reducing the complexity of the external circuitry. The device is RoHS compliant.
