Additional Details

The RB058LAM-40TFTR features a maximum repetitive reverse voltage (VRRM) of 40V and a maximum average forward rectified current (IF(AV)) of 0.5A. Its forward voltage drop is typically around 0.39V at 0.1A. The device is typically housed in a small surface mount package (such as a SOT-23 or similar), facilitating automated assembly and minimizing board space. This Schottky diode is characterized by its fast reverse recovery time, making it suitable for high-frequency applications where switching losses must be minimized.

The low forward voltage drop is a critical parameter for minimizing power dissipation in circuits. It allows the diode to conduct with minimal voltage loss, which is particularly important in battery-powered devices and energy-efficient systems. Additionally, the high surge current capability ensures the diode can withstand transient voltage spikes and surges without damage, improving the overall robustness of the application.
