The MMBT5401 with 150V 225mW 500mA 100@10mA,5V 100MHz 500mV@50mA,5mA -55?~+150?@(Tj) SOT-23 Bipolar Transistors - BJT ROHS is a Bipolar Junction Transistor (BJT) manufactured by JSMSEMI. This type of transistor is commonly used to switch and amplify electronic signals. It is designed with a base and two other terminals: collector and emitter. The MMBT5401 features a supra-high voltage of 150V, power dissipation of 225mW, current handling of 500mA, collector-emitter saturation voltage of 100@10mA,5V, and a frequency of 100MHz. It also has collecter-emitter breakdown voltage of 500mV@50mA,5mA, and an operating temperature range from -55? to +150?. The part is compliant with Restriction of Hazardous Substances (ROHS) standards and is provided in the SOT-23 package.
