Infineon BSR202N: A High-Performance N-Channel Logic Level MOSFET

In the realm of power electronics, efficient control and switching of power are paramount. The Infineon BSR202N stands out as a robust and highly efficient N-Channel logic level MOSFET engineered to meet these demanding requirements. This component is specifically designed to be driven directly from logic circuits, such as microcontrollers and GPIO pins (typically 3.3V or 5V), making it an indispensable part of modern low-voltage, high-efficiency applications.

A key strength of the BSR202N lies in its exceptional low gate-drive requirements. With a maximum gate threshold voltage (V_GS(th)) as low as 1.8V, it ensures full enhancement and minimal on-state resistance even when controlled by low-voltage logic signals. This capability eliminates the need for complex gate-drive circuitry, simplifying board design and reducing overall system cost and footprint.

The device boasts an impressively low on-state resistance (R_DS(on)) of just 50 mΩ (max) at a gate-source voltage of 4.5V. This characteristic is crucial for maximizing efficiency, as it directly translates to reduced conduction losses. When the MOSFET is switched on, the voltage drop across it is minimal, leading to lower power dissipation and significantly less heat generation. This makes the BSR202N ideal for power management tasks where thermal performance is a critical concern, such as in DC-DC converters, motor control circuits, and power switches.

Furthermore, the BSR202N is packaged in a compact and space-saving SOT-223 package. This package offers an excellent balance between physical size and thermal performance, providing a low thermal resistance path to the PCB for effective heat dissipation. Its ability to handle a continuous drain current (I_D) of up to 2.5A makes it suitable for a wide range of medium-power applications, from automotive systems and battery management to load switching and PWM control.

The combination of logic-level compatibility, low R_DS(on), and a robust package makes the Infineon BSR202N a superior choice for designers seeking to enhance the performance and reliability of their electronic systems.

ICGOO FIND: The Infineon BSR202N is a top-tier logic-level MOSFET that excels in low-voltage drive applications, offering high efficiency and excellent thermal performance due to its ultra-low on-resistance, making it a perfect fit for space-constrained and power-sensitive designs.
