STW11NK100Z STW15NK90Z N-channel 900V - 0.40 - 15A - TO-247 Zener - Protected SuperMESHTM PowerMOSFET General features Type VDSS (@Tjmax) STW15NK90Z 900 V RDS(on) ID PW < 0.55 15 A 350W Extremely high dv/dt capability 100% avalanche tested Gate charge minimized Very low intrinsic capacitances Very good manufacturing repeatibility TO-247 Description The SuperMESHTM series is obtained through an extreme optimization of ST's well established strip-based PowerMESHTM 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 MDmeshTM products.

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. 4/14 STW15NK90Z 2 Electrical characteristics Electrical characteristics (TCASE=25C unless otherwise specified) Table 5.
