MULTICOMP PRO BAS40 Surface Mount Barrier Diode

Surface Mount Barrier Diodes like BAS40 and its variants BAS40-04, -05, -06 are high-speed switching components designed for circuit protection, voltage clamping, and transient suppression. Featuring low turn-on voltage, fast switching capabilities, and a PN junction guard ring for ESD and transient protection, these diodes are ideal for high-speed applications. Packaged in SOT-23, they offer reliable performance with maximum ratings including a 40V peak reverse voltage, 350mW power dissipation, and junction temperatures up to 150°C. Suitable for modern electronic circuit protection solutions.
