ESD Protection Device Technology
ON Semiconductor’s portfolio contains three main
technologies for low capacitance ESD protection device
which are highlighted below and in Figure 15.
• ESD7000 series: Zener diode based technology. This
technology has a higher breakdown voltage (VBR)
limiting it to protecting chipsets with larger geometries.
• ESD8000 series: Silicon controlled rectifier (SCR) type
technology. The key advatange for this technology is a
low holding voltage (VH) which produces a deeper
snapback that results in lower voltage over high
currents as shown in the TLP results in Figure 16. This
technology provides optimized protection for chipsets
with small geometries against thermal failures resulting
in chipset damage (also known as “hard failures”).
• ESD8100 series: Low voltage punch through (LVPT)
technology. The key advatange for this technology is a
very low turn-on voltage as shown in Figure 17. This
technology provides optimized protection for chipsets
with small geometries against recoverable failures due
to voltage peaks (also known as “soft failures”).
