## Description
The B0540W RHG is a surface-mount Schottky barrier diode engineered by Taiwan Semiconductor in a compact SOD-123 plastic package. Featuring a 2-pin single configuration, this low-profile device supports a repetitive peak reverse voltage ($V_{RRM}$) of 40 V and a maximum average forward current ($I_O$) of 500 mA at a lead temperature of 100°C. Designed for high-frequency small-signal rectification and power management efficiency, the component exhibits a maximum forward voltage drop ($V_F$) of 510 mV at 500 mA ($T_J = 25^\circ\text{C}$), minimizing conduction power losses in space-constrained layouts.
Built for reliability in dense printed circuit board assemblies, the B0540W RHG handles a non-repetitive peak forward surge current ($I_{FSM}$) of 5.5 A based on an 8.3 ms single half sine-wave overlay. It features a matte tin lead finish with a nickel underplate, is rated for moisture sensitivity level 1 (MSL 1), and operates across a wide junction and storage temperature range of -55°C to +125°C. The component is fully compliant with RoHS Directive 2011/65/EU and is halogen-free in accordance with IEC 61249-2-21, utilizing green compound molding.
This Schottky rectifier is well-suited for low-power voltage conversion circuits, reverse polarity protection, high-frequency switching, and signal demodulation in consumer electronics and industrial automation equipment. Its minimal junction capacitance and fast reverse recovery characteristics help mitigate switching losses, while the standardized SOD-123 footprint ensures seamless integration via standard surface-mount reflow soldering profiles up to 260°C for 10 seconds.
