Small-signal Schottky for fast switching and tight spaces
The Infineon BAS140WE6327HTSA1 is a 40 V, 120 mA Schottky diode in a SOD-323 surface-mount package, built for high-speed switching where every picosecond counts. Its 100 ps reverse recovery time and low forward voltage of 1 V at 40 mA make it a natural fit for protection clamping, OR-ing diodes, and low-power rectification in battery-operated or portable gear. The junction temperature range spans -55°C to 150°C, so it handles the thermal cycling you see in outdoor telecom or under-hood automotive modules without derating headaches.
Package and handling on site
SOD-323 (SC-76) is a standard two-pin surface-mount package. The cathode is marked with a band on the body — orientation is obvious under a loupe, even on a crowded board. No special hot-air station needed; a soldering iron with a fine tip and some flux will swap it in the field if the board has accessible pads. The PG-SOD323-3D supplier package code is Infineon's internal variant — same footprint, same thermal pad, no surprises.
Lifecycle and compliance
It is ROHS3 compliant, so it passes the material declarations for EU and most global markets without an exemption waiver.
