Overview
The BAT54LT1G Schottky barrier diode, produced by onsemi, is designed for high-speed switching applications, circuit protection, and voltage clamping. This diode features an extremely low forward voltage, which reduces conduction loss and makes it ideal for applications where efficiency is crucial. The miniature surface mount package (SOT-23) is well-suited for handheld and portable devices where space is limited. The BAT54LT1G is also AEC-Q101 qualified and PPAP capable, making it suitable for automotive and other applications requiring unique site and control change requirements.
