The growing trend toward greater functionality and sophistication in smartphones and other mobile devices, while simultaneously reducing size and maintaining or even extending battery life, has led to increased demand for ultra-compact components that minimize power consumption, particularly Schottky barrier diodes used in power supplies, where low voltage (VF) and high rectified current are essential. However, until now, reducing VF and increasing current handling capacity has required increasing chip size, making miniaturization difficult.
In response, ROHM has significantly improved current efficiency through diode redesign, reducing VF by 32% compared to conventional products. This results in lower heat generation and higher current rating, allowing for smaller packages that can reduce the mounting area by up to 80%.
Main features.
1. High current in a compact package.
The low VF ensures high current handling capacity in a compact size.
2. Up to 80% reduction in mounting footprint.
Higher current rating allows for smaller form factors, significantly reducing the required mounting area.
Terminology.
VF (Forward Voltage)
The voltage when current flows through the diode in the forward direction. The lower the value, the lower the power consumption.
Average rectified current (Io)
The maximum rectified current that can flow in the forward direction under the specified conditions.
