RF ESD Protection Diodes
• ESD / transient protection of RF antenna /
interfaces or ultra high speed data lines acc. to:
IEC61000-4-2 (ESD): ± 20 kV (contact)
IEC61000-4-4 (EFT): 40 A (5/50 ns)
IEC61000-4-5 (surge): 10 A (8/20 µs)
• Ultra low capacitance of 1 pF typ.
(0.5 pF per diode)
• Low clamping voltage
• Pb-free (ROHS compliant) package
Applications in anti-parallel configuration
• For low RF signal levels without superimposed
DC voltage: e.g. GPS, WLAN, Bluetooth
Applications in rail-to-rail configuration
• For high RF signal levels or low RF signal levels
with superimposed DC voltage: e.g. HDMI, S-ATA,
Gbit Ethernet

The protection diode should
be placed very close to the
location where the ESD or
other transients can occur to
keep loops and inductances
as small as possible.
Pins 1 and 2 should be
connected in parallel directly
to a ground plane on the
board.
