MBT3904DW1T1G

Overview

The MBT3904DW1T1G is a dual NPN bipolar junction transistor manufactured by onsemi. It integrates two independent NPN transistors within a single SC-70-6 (SOT-363) surface-mount package. The device supports a maximum continuous collector current of 200 mA and offers a collector-emitter breakdown voltage of 40 V, with a collector-base voltage rating of 60 V and an emitter-base voltage limit of 6 V. Electrical performance includes a transition frequency of 300 MHz and a minimum DC current gain of 40. Thermal specifications define a power dissipation capacity of 150 mW and an operating temperature range from -55°C to +150°C.

Feature Summary
