Electrostatic discharge (ESD)
Triboelectric charging: Charge transfer due to the contact and separation of materials
- Electrons transfer from one material to the other
- You can acquire 5 – 15 thousands of volts of static charge
- By walking on carpet or moving your clothes or...
ESD: Charge transfer between bodies at different potentials
- You feel a shock when you touch something
- This shock will kill a chip
Most ICs have input protection
- But only good to about 2000V
