Infineon BAS70-04E6327: High-Speed Switching Dual Series Schottky Diode

In the realm of modern electronics, efficiency and speed are paramount. The Infineon BAS70-04E6327 stands out as a critical component engineered to meet these demands. This device is a high-speed switching dual series Schottky diode, specifically designed for applications where low forward voltage drop and ultra-fast switching are essential.

Schottky diodes, known for their metal-semiconductor junction, offer significant advantages over standard PN-junction diodes. The BAS70-04E6327 leverages this technology to provide a very low forward voltage drop of typically around 0.32V at 1mA. This characteristic is crucial for enhancing energy efficiency, especially in low-voltage, high-current applications, as it minimizes power loss and heat generation.

A key feature of this diode is its exceptionally fast switching speed. The absence of a minority charge carrier storage effect allows it to switch from the on-state to the off-state much faster than conventional diodes. This makes it an ideal choice for high-frequency circuits, such as RF detectors, mixers, and samplers, as well as in power supply functions like freewheeling diodes in switched-mode power supplies (SMPS) and DC-DC converters.

The BAS70-04E6327 is packaged as a common-cathode dual diode in the compact SOT-23 surface-mount device (SMD) package. This configuration is highly space-efficient and allows for the consolidation of two discrete diodes into a single component, simplifying board layout and reducing the overall footprint. Its robust construction ensures high reliability for automated assembly processes.

Furthermore, its performance is characterized by a low reverse leakage current and strong surge current capability, making it suitable for a wide range of commercial and industrial applications, including signal demodulation, clamping circuits, and reverse polarity protection.
