- Very low intrinsic capacitances - Very good manufacturing repeatibility ## **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. ## **Internal schematic diagram** **==> picture [126 x 144] intentionally omitted <==** ## **Applications** - Switching application ## **Order codes** |**Order codes**|||| |---|---|---|---| |**Part number**|**Marking**|**Package**|**Packaging**| |STD2NK90ZT4|D2NK90Z|DPAK|Tape & reel| |STD2NK90Z-1|D2NK90Z|IPAK|Tube| |STP2NK90Z|P2NK90Z|TO-220|Tube| _www.st.com_ 1/18 July 2006 Rev 4 |**Contents**|**STP2NK90Z - STD2NK90Z - STD2NK90Z-1**| |---|---| |**Contents**|| |**1**|**Electrical ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3**| ||1.1

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. 4/18 **STP2NK90Z - STD2NK90Z - STD2NK90Z-1** **Electrical characteristics** ## **2 Electrical characteristics** (TCASE=25°C unless otherwise specified) ## **Table 5.
