STW24NK55Z N-channel 550 V - 0.18 - 23 A - TO-247 Zener-protected SuperMESH Power MOSFET Features Type V R I Pw DSS DS(on) D STW24NK55Z 550 V <0.22 23 A 285 W Extremely high dv/dt capability 3 100% avalanche tested 2 1 Gate charge minimized TO-247 Very low intrinsic capacitances Very good manufacturing repeatability Application Switching applications Description Figure 1. Internal schematic diagram The SuperMESH series is obtained through an extreme optimization of STs well established strip-based 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. Table 1.
