The BAT 62 series from Infineon Technologies AG consists of Schottky diodes rated at 40V and 20mA. These diodes are commonly used in power supply circuits, battery chargers, and other low-power applications where fast recovery times and low forward voltage drops are important. If you're working on designs that require efficient switching and minimal power loss, these diodes can be a good fit. One thing worth noting is their suitability for buck converters and other switching regulators where reducing the diode drop can significantly improve overall efficiency. Engineers tend to reach for this when they need a compact, reliable solution that doesn’t compromise on performance. Another practical use case is in portable electronics where every milliwatt saved during operation can extend battery life.
