Low Reverse Current 100v Schottky Diode / Schottky Diode Forward
Voltage Drop
100v Schottky Diode Advantage
100v Schottky Diode has the advantages of high switching frequency and low forward
voltage, but its reverse breakdown voltage is relatively low,
mostly not higher than 60V, and the maximum is only about 100V,
which limits its application range. For example, in the switching
power supply (SMPS) and power factor correction (PFC) circuits, the
freewheeling diode of the power switching device, the transformer
secondary uses a high-frequency rectifier diode of 100V or more,
and the RCD snubber circuit uses a high-speed diode of 600V to
1.2kV. The PFC boost uses a 600V diode, etc., and only uses a fast
recovery epitaxial diode (FRED) and an ultra fast recovery diode
(UFRD). The reverse recovery time Trr of UFRD is also above 20 ns,
which cannot meet the needs of SMPS of 1 MHz to 3 MHz in fields
such as space stations. Even with a SMPS with a hard switch of 100
kHz, due to the large conduction loss and switching loss of the
UFRD, the case temperature is high, and a large heat sink is
required, so that the volume and weight of the SMPS are increased,
which is not compatible with miniaturization and thinning. The
development trend. Therefore, the development of high-pressure SBD
above 100V has always been a research topic and a hot spot of
concern. In recent years, SBD has made breakthroughs. High-voltage
SBDs of 150V and 200V have been launched. SBDs with more than 1kV
made of new materials have also been successfully developed, thus
injecting new vitality and vitality into their applications.
