The BAS40LT1G is a Schottky barrier diode intended for high-speed switching, circuit protection, and voltage clamping. It features a reverse voltage of 40 V and an extremely low forward voltage, such as 380 mV at 1.0 mA, which reduces conduction loss. Key characteristics include a low total capacitance of 5.0 pF and a maximum reverse leakage current of 1.0 µA at 25 V. Housed in a miniature SOT-23 surface-mount package, this diode is excellent for space-limited handheld and portable applications.
