Overview
The BAS40LT1 Schottky barrier diode, produced by onsemi, is designed for high-speed switching applications, circuit protection, and voltage clamping. This diode is notable for its extremely low forward voltage, which reduces conduction loss, making it highly efficient. It is packaged in a miniature surface mount SOT-23 (TO-236) package, which is ideal for handheld and portable applications where space is limited. The BAS40LT1 is also Pb-free, halogen-free/BFR-free, and RoHS compliant, ensuring environmental sustainability and regulatory compliance.
