RoHS Approved Schottky Diode Guard Ring For Overvoltage Protection

Guard Ring For Overvoltage Protection Schottky Diode With RoHS​

Advantage

SBD 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 highest is only about 100V, which limits its application range. Such as freewheeling diodes of power switching devices in switching power supply (SMPS) and power factor correction (PFC) circuits, high-frequency rectifier diodes above 100V for transformer secondary, high-speed diodes of 600V~1.2kV in RCD snubber circuits, and For 600V diodes used in PFC step-up, only fast recovery epitaxial diodes (FRED) and ultra-fast recovery diodes (UFRD) are used. The reverse recovery time Trr of UFRD is also more than 20ns, which cannot meet the needs of 1MHz~3MHz SMPS in fields such as space stations. Even for an SMPS with hard switching at 100kHz, due to the large conduction loss and switching loss of UFRD, the case temperature is high, and a large heat sink is required, which increases the size and weight of the SMPS, which does not meet the miniaturization and thinning requirements. development trend. Therefore, the development of high-voltage SBDs above 100V has always been a research topic and a focus of attention. In recent years, SBD has made breakthrough progress, 150V and 200V high-voltage SBDs have been listed, and the SBD of more than 1kV made of new materials has also been successfully developed, thus injecting new vitality and vitality into its application.
