STW26NM50 N-CHANNEL 500V - 0.10Ω - 30A TO-247 MDmesh™ MOSFET Table 1: General Features TYPE STW26NM50 ■ ■ ■ ■ Figure 1: Package VDSS RDS(on) ID 500 V < 0.120 Ω 30 A TYPICAL RDS(on) = 0.10 Ω HIGH dv/dt AND AVALANCHE CAPABILITIES IMPROVED ESD CAPABILITY LOW INPUT CAPACITANCE AND GATE CHARGE DESCRIPTION The MDmesh™ is a new revolutionary MOSFET technology that associates the Multiple Drain process with the Company’s PowerMESH™ horizontal layout. The resulting product has an outstanding low on-resistance, impressively high dv/dt and excellent avalanche characteristics. The adoption of the Company’s proprietary strip technique yields overall dynamic performance that is significantly better than that of similar competition’s products. TO-247 Figure 2: Internal Schematic Diagram APPLICATIONS The MDmesh™ family is very suitable for increasing power density of high voltage converters allowing system miniaturization and higher efficiencies.

Max. Unit V 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. 2/9 STW26NM50 Table 7: On /Off Symbol Parameter Test Conditions Min. Typ.
