DESCRIPTION
The SuperMESH™ series is obtained through an
extreme optimization of ST’s well established
stripbased PowerMESH™ layout. In addition to
pushing on-resistance significantly down, special
care is taken to ensure a very good dv/dt capability
for the most demanding applications. Such series
complements ST full range of high voltage MOSFETs including revolutionary MDmesh™ products.

APPLICATIONS
■ HIGH CURRENT, HIGH SPEED SWITCHING
■ IDEAL FOR OFF-LINE POWER SUPPLIES,
ADAPTORS AND PFC
■ LIGHTING

PROTECTION FEATURES OF GATE-TO-SOURCE ZENER DIODES
The built-in back-to-back Zener diodes have specifically been designed to enhance not only the device’s
ESD capability, but also to make them safely absorb possible voltage transients that may occasionally be
applied from gate to source. In this respect the Zener voltage is appropriate to achieve an efficient and
cost-effective intervention to protect the device’s integrity. These integrated Zener diodes thus avoid the
usage of external components.
