High Voltage No Longer an Issue with Driving SiC MOSFETs

Posted on November 30, 2017 Michael Rodriguez Electronics

Many users have experienced the unfortunate event of having their SiC MOSFETs over heat due to high voltages and switching of the voltages. Many of the SiC MOSFETs have been worn down due to isolation barriers. Due to unfortunate events such as these the Electronic Company RECOM, they have created a new way to not only save the unit but increase its longevity when continuously switching the voltage. RECOM released a 2W DC/DC converter family that is specifically designed for the newest SiC MOSFETs editions. The RxxP21503D has become a key part for the SiC MOSFETs when turning the voltages on and off which is one of the SiCs most common characteristics.

The RxxP21503D has is able to meet the second-generation requirements by omitting voltages of +15 and -3V. One of the dangers that often occurs with the average DC/DC isolation voltage is the overheating of having to put in twice than the standard one. Not only does the unit have the possibility of overheating from over working but can experience over heating due to the increasing temperature of the environment the unit is placed.

Recoms newest releases is able to still fit into a standard “SIP7” case and is optimized with stand the worst conditions these types of units have to face. To be able to withstand the worst conditions the UNIT has been installed with a 6.4kVDC isolation voltage to ensure that the barriers are reinforced. The units come in different varieties to be able to with stand different types of assemblies.

“These converters are available with input voltages of 12, 15 or 24V and come equipped with ultra-low parasitic capacitance (less than 10pF). They are EN-60950-1 certified and fully compliant to RoHS2 and REACH.”


To be able to work alongside the RECOM unit it must be placed with quality components due to the high voltage usage. Due to RECOMs confidence in their product they offer a three-year warranty and have released samples to authorized distributors around the nation.
