| STW14NM50 N-CHANNEL 550V @ Tjmax - 0.32 - 14A TO-247 MDmeshTM MOSFET Table 1: General Features TYPE STW14NM50 s s s s Figure 1: Package RDS(on) < 0.35 ID 14 A VDSS (@Tjmax) 550 V s s TYPICAL RDS(on) = 0.32 HIGH dv/dt AND AVALANCHE CAPABILITIES 100% AVALANCHE RATED LOW INPUT CAPACITANCE AND GATE CHARGE LOW GATE INPUT RESISTANCE TIGHT PROCESS CONTROL AND HIGH MANUFACTORING YIELDS TO-247 DESCRIPTION The MDmeshTM is a new revolutionary MOSFET technology that associates the Multiple Drain process with the Company's PowerMESHTM 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 proprierati strip technique yields overall dynamic performance that is significantly better than that of similar completition's products. APPLICATIONS The MDmeshTM family is very suitablr for increase the power density of high voltage converters allowing system miniaturization and higher efficiencies.
