Applications
•MOSFET protecti on
•IGBT protection
•Auxiliary power supply
Description
The STRVSX series is a TVS family created to
provide simple and effective solutions for
designers working on circuits that require
protect ion from repetitive overvoltage.
The STRVSX series is highly reliable and suits
applications where the surge frequency makes
the protected device tempe ra ture increase, for
example , MOS FET prot ection in fly back
configuration.
Additi onal support for designers using these
device s is available in the STMicroele ctronics
application not e AN4 209: “Design methodolo gy
for repetiti ve voltage suppressors ( RVS) in
repetitive mode: STRVS”.
