ESD1P0RFW Visão geral
RF ESD protection is a specialized form of circuit protection used to shunt transient voltage away from low-voltage radio-frequency or high-speed interface circuitry. This device belongs to the TVS diode and surge-protection hierarchy, where fast, low-capacitance clamping preserves high-frequency signal integrity better than a conventional power TVS diode.
The key feature is its ultra-low 1 pF typical line capacitance to ground, reported as 0.5 pF per diode. Low capacitance limits loading of RF and ultra-high-speed data lines while still providing transient protection. The device is specified for IEC 61000-4-2 contact discharge to 20 kV, IEC 61000-4-4 EFT at 40 A, and IEC 61000-4-5 surge at 10 A using the indicated pulse waveforms.
The six-pin SOT-323 arrangement supports an anti-parallel protected signal-line configuration, as shown in the manufacturer application example. The diode structure can operate with superimposed DC voltage up to ±VF, but the exact forward-voltage and DC operating limits must be taken from the complete manufacturer datasheet before final circuit sign-off.
Typical applications include GPS antenna inputs, RF antenna connectors, HDMI interfaces, Ethernet ports, and ultra-high-speed data lines. The low capacitance makes ESD1P0RFW most useful where transient suppression must be added without materially degrading signal bandwidth.
Designers should place the protection device close to the connector or board entry point, route the protected signal on the protected side of the device, and verify that the package footprint and pin mapping match the PCB land pattern. Apply the manufacturer’s recommended layout and grounding practice to maximize surge-current handling and minimize parasitic inductance.
This page combines verified Infineon specifications, distributor references, practical protection-layout guidance, and a strict assessment of drop-in alternatives. Because the supplied cross-reference data identifies no validated same-package substitute, no unverified replacement MPNs are presented.

Aplicações típicas
ESD1P0RFW é adequado para 6 aplicaçãos: GPS Antenna Input Protection, RF Antenna and Radio Interface Protection, HDMI Interface Protection, Ethernet Port Transient Protection, Ultra-High-Speed Data-Line Protection, Embedded RF and Wireless Module Interfaces.
GPS Antenna Input Protection
The ESD1P0RFW fits a GPS antenna connector because Infineon lists GPS as a target application and specifies only 1 pF typical capacitance to ground. Placing the device near the RF entry point provides ±20 kV contact ESD protection while limiting the capacitance introduced into the antenna path. The protection still requires system-level validation because connector loss, antenna impedance, and transient coupling determine the final ESD margin. Use the manufacturer’s anti-parallel application arrangement and keep the layout path short.
Recomendado
RF Antenna and Radio Interface Protection
For RF antenna inputs, ESD1P0RFW provides a compact way to add transient protection without the higher capacitance associated with general-purpose TVS protection. The verified 1 pF typical line capacitance helps preserve high-frequency behavior, while ±20 kV contact ESD and 10 A surge compliance address connector-borne transients. The device should be positioned at the board boundary, with the protected circuitry on the device side and a low-inductance grounding arrangement. Validate insertion loss and impedance continuity in the final antenna path.
Recomendado
HDMI Interface Protection
ESD1P0RFW is applicable to HDMI entry points where transient suppression must coexist with a high-speed signal path. Infineon identifies HDMI as an intended application and specifies 1 pF typical capacitance, which helps control loading at the connector. The device is most useful when placed directly behind the external connector and before long protected traces or sensitive receiver circuitry. Engineers should still verify differential impedance, edge-rate margin, return loss, and the complete connector-plus-protection capacitance budget.
Recomendado
Ethernet Port Transient Protection
The ESD1P0RFW can be used at Ethernet line-entry points when low capacitance and high contact-discharge capability are required together. Its verified 1 pF typical line capacitance avoids intentionally adding the larger capacitance of a general-purpose suppressor, while ±20 kV contact ESD protection addresses the specified transient threat. Place the device close to the connector and route surge current through a short ground return. Confirm the exact Ethernet topology, bias conditions, and channel capacitance against the production interface specification.
Recomendado
Ultra-High-Speed Data-Line Protection
For ultra-high-speed data lines, ESD1P0RFW is suitable when the protection device’s capacitance must remain small enough to preserve the intended signal bandwidth. The verified 1 pF typical line capacitance is the central benefit, together with ±20 kV contact ESD capability. The device should be placed at the board entry point, not deep in the signal path, and its ground connection should minimize inductance. Confirm edge-rate degradation, impedance continuity, and return loss with the complete channel and connector model.
Recomendado
Embedded RF and Wireless Module Interfaces
Embedded wireless modules can benefit from ESD1P0RFW at exposed RF or high-speed connector boundaries where accidental contact discharge is a concern. The low 1 pF typical capacitance helps avoid unnecessary loading of sensitive module interfaces, while the 10 A surge rating provides a defined transient target. The exact protection arrangement must follow the module vendor’s grounding and keep-out guidance. Validate the system’s antenna matching, module sensitivity, and enclosure discharge path before treating the protection as sufficient.

- Known distributor availability (vs Unverified alternative sourcing)
Notas de projeto
Place ESD1P0RFW immediately adjacent to the external RF or high-speed connector so surge current reaches the protection device before the signal reaches sensitive circuitry. Route the protected signal on the protected side of the diode network and keep the ground return short and low inductance. The manufacturer datasheet’s anti-parallel application example is the relevant topology reference; do not move the device deep into the PCB without revalidating transient-current paths.
Use the verified 1 pF typical line capacitance as part of the complete interface budget, not as an isolated device number. Connector capacitance, receiver input capacitance, trace discontinuities, and protection-device capacitance can combine to reduce edge-rate margin. For GPS, RF, HDMI, or Ethernet interfaces, compare the calculated loading with the channel specification and verify return loss and impedance continuity using the final layout.
Do not select a replacement based only on the phrase TVS diode. Confirm exact SOT-323 footprint dimensions, pin mapping, capacitance, stand-off voltage, clamping behavior, and transient test conditions. ESD1P0RFW is specified at ±20 kV contact ESD, 40 A EFT, and 10 A surge in the supplied data, but those ratings must remain valid for the actual ordering suffix, bias condition, pulse waveform, and system layout.
