Product details
Overview
RClamp0561Z.TFT from Semtech is an ultra-low-capacitance (0.12 pF typical), single-line ESD protection diode in a 2-pin SGP0603P2X3 package (0.62 × 0.32 mm), rated for 5.5 V working voltage and ±12 kV IEC 61000-4-2 contact ESD immunity - designed specifically to protect high-speed differential data lines such as HDMI 2.0, USB 3.1, and Thunderbolt without signal integrity degradation.
For engineers reviewing the RClamp0561Z.TFT datasheet, pinout, applications, or equivalent options, key selection criteria include sub-0.15 pF capacitance, 17.5 GHz bandwidth, low 0.15 dB insertion loss at 5 GHz, clamping voltage ≤20 V at 2 A (8/20 µs), and compatibility with 10 Gb/s serial interfaces requiring minimal trace-length impact and no impedance discontinuity.
Technical Context
RClamp0561Z.TFT employs silicon-avalanche TVS technology with symmetrical bidirectional clamping, enabling protection of AC-coupled high-speed differential pairs without polarity constraints. Its dynamic resistance is 1.5 Ω (TLP, 4–16 A), ensuring rapid response and low-voltage clamping during ESD transients.
The device operates within -40°C to +85°C junction temperature range, maintains ≤50 nA reverse leakage at 5.5 V, and achieves 17.5 GHz -3 dB cutoff frequency - validated via eye diagram testing at 3.4 Gb/s (HDMI 1.4), 5.94 Gb/s (HDMI 2.0), and 10 Gb/s (USB 3.1).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (CJ) | 0.12 pF typical at 0 V, 1 MHz - preserves signal integrity on >10 Gb/s links with negligible impedance mismatch. |
| ESD Withstand | ±12 kV contact / ±15 kV air per IEC 61000-4-2 - meets industrial and consumer interface immunity requirements. |
| Clamping Voltage (VC) | ≤20 V at 2 A (8/20 µs) - limits transient overvoltage seen by downstream PHY ICs. |
| Bandwidth | 17.5 GHz (-3 dB cutoff) - supports full-rate HDMI 2.0 (5.94 Gb/s), USB 3.1 Gen 2 (10 Gb/s), and Thunderbolt 3. |
| Insertion Loss | 0.15 dB typical at 5 GHz - ensures <0.2 dB total loss across critical high-frequency operating bands. |
| Package | SGP0603P2X3 (0.62 × 0.32 × 0.30 mm) - enables placement directly at connector pads with minimal PCB area. |
| Working Voltage (VRWM) | 5.5 V - matches standard 5 V I/O rails of USB, HDMI, and MIPI host controllers. |
Pinout & Package

Applications
| HDMI 2.0 Interface Protection | USB 3.1 Gen 2 Channel Protection |
|---|---|
|
Use Scenario: Protecting TMDS clock/data lanes on 4K@60Hz HDMI 2.0 source or sink PCBs against ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed between each TMDS+/- line and chassis ground, preserving differential impedance and common-mode rejection. Use Value: Maintains 5.94 Gb/s eye margin (tested) with <0.2 dB loss at 3 GHz, preventing HDMI link training failure due to ESD-induced jitter or amplitude collapse. |
Use Scenario: ESD protection of SuperSpeed TX/RX differential pairs in USB 3.1 Gen 2 host or device ports supporting 10 Gb/s operation. IC Role / Device Role / Timing Role: Single-line symmetrical clamp per lane, installed adjacent to USB Type-C receptacle on both top/bottom PCB layers to support reversible plug insertion. Use Value: Enables clean 10 Gb/s eye diagrams (validated) with ≤0.15 dB insertion loss at 5 GHz, avoiding signal integrity penalties from higher-capacitance alternatives. |
| Thunderbolt 3 Data Lane Protection | MIPI D-PHY / C-PHY Line Protection |
|
Use Scenario: Board-level ESD hardening of Thunderbolt 3 controller outputs driving passive cables or docks, where transient suppression must not degrade PCIe Gen 3 or DisplayPort 1.2a signaling. IC Role / Device Role / Timing Role: Per-lane TVS clamp on DP++/PCIe differential pairs, leveraging 17.5 GHz bandwidth to pass full Thunderbolt 3 spectral content. Use Value: Prevents ESD-induced link retraining or display flicker by clamping transients below 20 V while adding <0.2 dB loss at 8 GHz - critical for stable 40 Gbps aggregate throughput. |
Use Scenario: Protecting MIPI D-PHY (1.5–2.5 Gb/s) or C-PHY (up to 3.5 Gsps) camera/display links in mobile and automotive infotainment systems exposed to handling ESD. IC Role / Device Role / Timing Role: One RClamp0561Z.TFT per data lane (CLK, DATA0–2), mounted directly at flex-to-PCB connectors to minimize stub length. Use Value: Delivers <0.1 pF added capacitance - avoids timing skew and bit error rate increase in multi-lane MIPI bundles, validated in 2.5 Gb/s D-PHY eye tests. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.5 pF typical capacitance, 5.5 V VRWM, ±12 kV ESD, SOT-563 package (1.6 × 1.6 mm) | Larger footprint, higher capacitance - suitable only for ≤5 Gb/s interfaces like USB 3.0 or HDMI 1.4. | Select when board space permits larger package and bandwidth requirement is ≤8 GHz. |
| SP1003-01UTG | 0.25 pF typical capacitance, 5 V VRWM, ±15 kV ESD, 0201 package (0.6 × 0.3 mm), 12.5 GHz bandwidth | Lower bandwidth (12.5 vs. 17.5 GHz) and higher capacitance - marginal for full-rate USB 3.1 Gen 2 or HDMI 2.0. | Choose only if cost sensitivity outweighs need for 10 Gb/s margin and tighter eye opening. |
Compared with TPD4E05U06DQAR and SP1003-01UTG, RClamp0561Z.TFT delivers the lowest capacitance (0.12 pF) and highest bandwidth (17.5 GHz) in a 0.62 × 0.32 mm footprint - making it the only option validated for 10 Gb/s USB 3.1 Gen 2 and 5.94 Gb/s HDMI 2.0 without signal degradation.

FAQ
What is the maximum data rate supported by RClamp0561Z.TFT without signal integrity loss?
RClamp0561Z.TFT supports up to 10 Gb/s (USB 3.1 Gen 2, Thunderbolt 3) with validated eye diagrams and 0.15 dB insertion loss at 5 GHz. Its 17.5 GHz -3 dB bandwidth and 0.12 pF capacitance ensure minimal jitter and amplitude degradation - confirmed in HDMI 2.0 (5.94 Gb/s) and USB 3.1 (10 Gb/s) eye testing per Semtech's datasheet Rev 6.1.
Is RClamp0561Z.TFT polarity-sensitive during PCB layout?
No, RClamp0561Z.TFT is electrically symmetrical - both terminals function identically as anode/cathode. This allows flexible placement on differential pairs without orientation constraints, simplifying routing for USB Type-C top/bottom layer protection and eliminating risk of reverse installation. The datasheet explicitly states "Device is electrically symmetrical" on page 9.
What is the recommended PCB land pattern for RClamp0561Z.TFT?
Semtech specifies a solder land pattern matching IPC-7351B for SGP0603P2X3: 0.62 mm × 0.32 mm pad size, 0.175 mm stencil aperture width, and 0.272 mm length (page 7). A 0.075 mm laser-cut electropolished stencil with rectangular apertures and rounded corners is recommended to achieve reliable solder joints on this 0.62 × 0.32 mm device.
Does RClamp0561Z.TFT meet IEC 61000-4-2 Level 4 ESD requirements?
Yes, RClamp0561Z.TFT exceeds IEC 61000-4-2 Level 4: it is rated for ±12 kV contact discharge and ±15 kV air discharge (page 2, Absolute Maximum Ratings). This qualifies it for industrial and commercial equipment requiring the highest ESD immunity class without external shielding or additional protection stages.
Can RClamp0561Z.TFT be used to protect USB Type-C CC and SBU pins?
No - RClamp0561Z.TFT is optimized for high-speed data lines (e.g., SuperSpeed TX/RX) and not recommended for CC/SBU pins. Semtech's Application Information (page 6) specifies RClamp5011ZA for CC/SBU protection due to its lower dynamic resistance (0.25 Ω) and 0.45 pF capacitance, better suited for low-speed control signals with different clamping and leakage requirements.
