Additional Details

The UNR2119 contains an NPN transistor with two built-in resistors. It has an input resistor of 10 kΩ and a resistor between base and power supply of 10 kΩ. The collector current is typically 100mA. The supply voltage can be up to 50V. The device is commonly used in applications where a simple, space-saving solution for switching or amplification is needed. Its integrated resistors eliminate the need for external biasing components, streamlining the design process. The UNR2119 is particularly useful in portable devices and other space-constrained applications. It helps to reduce the overall bill of materials and assembly time in electronic manufacturing. The small SOT-346 package allows for high-density board layouts.
