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. 5/19 Doc ID 17548 Rev 4 **STF4N62K3, STFI4N62K3, STI4N62K3, STP4N62K3, STU4N62K3** **Electrical characteristics** ## **2.1 Electrical characteristics (curves)** **Figure 2.
