ONPZT3904T1G
Overview
The PZT3904T1G is a surface-mount NPN bipolar junction transistor (BJT) housed in a SOT-223 package, designed for general-purpose switching and amplification. It provides a significant power dissipation upgrade over standard SOT-23 variants, supporting up to 1.5 W while maintaining the characteristics of the industry-standard 3904 series. This device features a transition frequency of 300MHz and a maximum collector current of 200 mA.
Why Choose This Part
The primary advantage is the SOT-223 package, which allows for 1.5 W of power dissipation compared to the 350 mW typical of a SOT-23 3904. It maintains a high DC current gain (hFE) of at least 100 at 10mA, ensuring efficient performance in low-current switching applications.

Key Specifications
Getting Started
When designing with this part, ensure the large collector tab is soldered to a sufficient copper plane for optimal thermal performance. Use standard spice models for the 2N3904 for simulation, as the electrical characteristics are matched to that family.
