NSB4904DW1T1G

Overview

The NSB4904DW1T1G is a digital transistor array manufactured by onsemi, featuring two NPN transistors integrated with base resistors in a compact SOT-323-6 surface-mount package. This component provides a typical input resistance of 47 kOhms and maintains a resistor ratio of 1. It supports a maximum collector-emitter voltage (VCEO) of 50 V and handles a continuous collector current of 100 mA. The device ensures a minimum DC collector/base gain (hfe) of 80, making it suitable for switching applications requiring dual NPN configurations within space-constrained designs.
