NJT4031NT3G Description

Short technical summary and product information.

The NJT4031NT3G from On Semiconductor is an NPN silicon bipolar junction transistor (BJT) housed in a SOT-223 package. This device is rated for a maximum collector-emitter voltage of 40V and a continuous collector current of 3A, with a peak current capability of 5A.

 

Key electrical characteristics include a continuous base current of 1A and a DC current gain (hFE) of 200 at 1A and 1V. The saturation voltage (Vce(sat)) is a maximum of 300mV at 300mA and 3A.

 

With a power dissipation rating of 2.0W (on a 1-inch sq. collector pad on FR-4) and an operating temperature range of -55°C to +150°C, the NJT4031NT3G is suitable for various power switching and amplification applications. The transistor is Pb-Free and Halogen Free, meeting RoHS compliance standards.

 

Mounting is via surface mount technology. The SOT-223 package (also known as TO-261AA) is commonly used for power applications where space is a consideration. The device is supplied in tape and reel packaging.
