THAT Corporation Bipolar Transistors - BJT 300AS14-U

The THAT 300AS14-U is a monolithic NPN transistor array containing four matched transistors in an SO14 package, designed for low-noise amplifier input stages, log amplifiers, and current mirrors. Each transistor has a minimum current gain (hFE) of 150, a collector-emitter voltage rating of 36 V, and a collector current rating of 30 mA. The array exhibits a typical voltage noise density of 0.8 nV/√Hz, a gain-bandwidth product of 350 MHz, and less than 0.5 mV matching in base-emitter voltage between devices. The transistors are dielectrically isolated to minimize crosstalk and maximize DC isolation.
