I am using the following diodes for ESD proection of IO for some pins of MCU
There are some ESD Diodes for 3.3V and some on 5V (USB VBus and some external inputs that are 5V)
I am using the following parts
No. Make Ordering code Voltage
1 Nexperia PESD3V3V1BCZF 3.3 V
2 Nexperia PESD5V0X1BL 5V
My doubt is... Can we really use a 3V3 TVS on 3.3V line. and 5V TVS for 5V line. Wouldn’t it just conduct at that voltage and give false results.
My test requirements are for 8KV
