Description
The STTH240F04 uses ST’s 400 V planar
technology. The STTH240F04 is especially suited
for switching welding equipments.
The device, housed in ISOTOP package, has in
the meantime a low thermal resistance, and a
high electrical isolation, which make it particularly
efficient in high power converters requiring to be
safe for the end user.
