RB420DT146 Description

Short technical summary and product information.

The RB420DT146 is a Schottky barrier diode from ROHM Semiconductor. It is designed for low-power rectification and switching applications requiring a low forward voltage drop. The diode has a maximum reverse voltage of 40V and an average rectified current rating of 100mA. At a forward current of 10mA, the maximum forward voltage is 450mV. The reverse leakage current is 100µA at the rated reverse voltage.

 

The device is housed in a compact SMD3 package (TO-236-3 / SC-59 / SOT-23-3) and is intended for surface mount assembly. The junction capacitance is typically 6pF at 10V and 1MHz, making it suitable for high-frequency applications. The maximum operating junction temperature is 125°C. This diode is suitable for use in general-purpose rectification, polarity protection, and low-voltage clamping circuits where Schottky characteristics are beneficial.
