ADC144EUQ-7

Bipolar Transistor Arrays, Pre-Biased Overview

The ADC144EUQ-7 is a dual NPN pre-biased transistor array manufactured by Diodes Incorporated. It integrates two NPN transistors with built-in biasing resistors (R1 and R2, both nominally 47 kΩ) within a compact SOT-363 surface-mount package. The device supports a maximum supply voltage of 50 V and a continuous collector current of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 68 at 5 mA and a transition frequency (fT) of 250 MHz. It operates within a temperature range of -55°C to +150°C and dissipates up to 270 mW of power.
