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 5/10 Doc ID 17338 Rev 1 **STS1DN45K3** **Test circuits** ## **3 Test circuits** **==> picture [399 x 21] intentionally omitted <==** **----- Start of picture text -----**
