Infineon BAT62-02W Silicon Schottky Barrier Diode: Characteristics and Applications

The Infineon BAT62-02W is a high-performance silicon Schottky barrier diode designed for a wide range of applications, particularly where low forward voltage drop and fast switching speeds are critical. As a surface-mount device in the SOD-323 package, it is well-suited for modern, space-constrained electronic designs. This diode leverages the fundamental advantages of Schottky barrier technology, making it a preferred choice in power rectification and high-frequency circuits.

One of the most significant characteristics of the BAT62-02W is its extremely low forward voltage drop, typically around 0.3V to 0.4V at low currents. This is substantially lower than that of standard PN-junction diodes, which results in higher efficiency and reduced power loss in circuits. This feature is especially beneficial in low-voltage, high-current applications, such as power supplies and DC-DC converters, where minimizing energy dissipation is paramount.

Another key attribute is its fast switching capability. Schottky diodes are majority carrier devices, meaning they do not suffer from minority carrier storage effects that cause reverse recovery time delays in conventional diodes. The BAT62-02W exhibits negligible reverse recovery time, enabling it to operate effectively at high frequencies without the performance degradation associated with recovery losses. This makes it ideal for use in switching regulators, RF detectors, and signal demodulation circuits.

The device is also characterized by its low junction capacitance, further enhancing its high-frequency performance. This allows it to function efficiently in very fast switching applications without being limited by capacitive loading effects. Additionally, the BAT62-02W offers good thermal stability and is encapsulated in a package suitable for automated assembly processes.

In terms of applications, the BAT62-02W is extensively used in:

Power Rectification: Serving as a rectifier in low-voltage switch-mode power supplies (SMPS) and DC-DC converters to improve overall efficiency.

Reverse Polarity Protection: Safeguarding sensitive electronic circuits from damage caused by incorrect battery or power supply insertion.

High-Frequency Circuits: Acting as a detector in RF applications and in clamping circuits due to its fast response time.

Signal Demodulation: Used in mixers and demodulators for recovering information from high-frequency carrier signals.

ICGOOODFIND: The Infineon BAT62-02W Schottky diode stands out for its low forward voltage, fast switching speed, and high-frequency capability, making it an excellent component for enhancing efficiency and performance in modern power and RF electronic designs.
