Infineon BAS4004E6327HTSA1: A High-Performance Schottky Diode for Power Electronics Applications

In the rapidly evolving field of power electronics, efficiency, speed, and thermal performance are paramount. The Infineon BAS4004E6327HTSA1 stands out as a critical component engineered to meet these demanding requirements. This Schottky barrier diode is specifically designed to deliver superior performance in a compact SMD (Surface Mount Device) package, making it an ideal choice for a wide array of modern applications.

At the heart of its design is the Schottky barrier principle, which enables a very low forward voltage drop (VF), typically around 0.37V at 1A. This characteristic is fundamental for enhancing system efficiency, as it minimizes power losses and reduces heat generation during operation. Furthermore, the device boasts an extremely fast switching speed, virtually eliminating reverse recovery losses that are common in standard PN-junction diodes. This makes it exceptionally suitable for high-frequency circuits, such as switch-mode power supplies (SMPS), DC-DC converters, and inverters, where switching performance directly impacts overall efficiency and electromagnetic interference (EMI).

The BAS4004E6327HTSA1 is characterized by its high current capability with a maximum average forward current (IF(AV)) of 1A and a repetitive peak reverse voltage (VRRM) of 40V. Its SOT-23 package offers excellent thermal properties and is designed for automated assembly, catering to the needs of high-volume manufacturing. The device also features a low thermal resistance and a wide operating junction temperature range from -65 °C to +125 °C, ensuring reliable performance even under strenuous conditions.

Key application areas include:

Power rectification in AC-DC adapters and power supplies.

Freewheeling and clamping diodes in motor control and inductive load circuits.

Reverse polarity protection circuits.

Output rectification in high-frequency DC-DC converters.

ICGOODFIND: The Infineon BAS4004E6327HTSA1 is a high-efficiency, fast-switching Schottky diode that provides an optimal solution for reducing energy losses and improving thermal management in space-constrained, high-frequency power electronic designs.
