There are many type of ESD sensitive parts. Some of the most ESD sensitive parts used in the Electronic Industry are:

• Radio Frequency components
• Disk Drive head (Magneto resistive heads (MR), Giant Magneto resistive heads (GMR))
• Complementary Metal Oxide Silicon (CMOS) Integrated Circuits (ICs)
• Gallium Arsenide Field Effect transistors (GaAsFETs)
• Reticles
• Random Access Memory (RAM) chips Among the all, GMR is the most sensitive parts with ESD withstand voltage in a few volt range.
  

The ESD sensitivity level for majority of modern ESD sensitive parts are documented in their component datasheets. The threshold voltage for Human Body Model (HBM), Machine Model (MM), Charge Device Model (CDM) for the ESD sensitive parts is in the datasheets. ESD sensitive parts are packaged in the ESD packaging that suits the parts. The ESD sensitive parts can be identified through an ESD symbol. The most commonly used ESD symbols are described here:

• A bar is across the human’s hand
• Three arrows pointing inwards (this is an obsolete Military symbol but it is still widely used by component manufacturers)

These symbols are either printed in paper sign-labels or permanently imprinted in the part’s packaging, for example the ESD symbol is placed on the reels.

A proper handling of ESD sensitive parts is required when handling the ESDS parts.
