RF ESD Protection Diodes
• ESD protection of RF antenna /
interfaces or ultra high speed data lines acc. to:
IEC61000-4-2 (ESD): ± 15 KV (air / contact)
IEC61000-4-4 (EPT): 40 A (5/50 ns)
IEC61000-4-5 (surge): 5 A (8/20 µs)
• Very low line capacitance: 0.4 pF @ 1 GHz
( 0.2 pF per diode)
• Ultra low series inductance: 0.4 nH per diode
• Very low clamping voltage
• Ultra small leadless package:1.2 x 0.8 x 0.39 mm³
• Pb-free (RoHS compliant) package
Applications in anti-parallel configuration
• For low RF signal levels without superimposed
DC voltage: e.g. GPS, XM-Radio, Sirius, DVB,
DMB, DAB, Remote Keyless Entry
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

1. Application example ESD0P4RFL
1 RF signal channel, anti-parallel configuration
ESD0P4RFL
1 protected signal line,
superimposed DC voltage up to
±VF (diode forward volatge)
I/O
ESD
sensitive
circuit
Line to ground capacitance
0.4 pF @1 GHz
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.
Grounded pins should be
connected in parallel directly to a
ground plane on the board.
2. Application example ESD0P4RFL
1 RF signal channel, rail-to-rail configuration
1 protected signal line,
superimposed DC voltage up to
+Vcc (voltage supply)
I/O
ESD
sensitive
circuit
Line to ground capacitance
0.4 pF @1 GHz
+Vcc
Cathode of one diode should be
connected to the positive supply
voltage +Vcc and anode of the
opposite diode should be
connected directly to a ground
plane on the board. Clamped
input voltage at I/O port is limited
to Vcc + VF at positive transients
and 0V - VF at negative transients
(VF ... diode forward voltage
drop).
