The DTA144EE transistor from Luguang is a PNP Bipolar Junction Transistor (BJT) with a Breakdown Voltage (BRT) of 50V, a continuous collector current of 0.1A, a total power dissipation of 150mW, a SOT523 package, and a 47kO resistance. This transistor is designed for general purpose switching and amplifying circuits in an array of applications. It can handle switching frequencies of up to 200KHz and can be used for low-side or high-side switching. It is also capable of providing fast rise and fall times with a low collector-emitter saturation voltage. It is an efficient solution for low-voltage power management, interface, and on/off switching circuits in power supplies, audio amplifiers, and data converters.
