Product details
Overview
RCLAMP3328P.TNT from Semtech is an 8-line, low-capacitance ESD protection diode array designed for high-speed differential interfaces including USB 3.0, HDMI 1.4, and V-By-One. It delivers ±30kV air/±25kV contact IEC 61000-4-2 ESD protection, 0.65pF max I/O-to-ground capacitance, and 0.35Ω typical dynamic resistance in a 9-pin SGP3810N9 package (3.8 × 1.0 × 0.50 mm).
For engineers reviewing the RCLAMP3328P.TNT datasheet, pinout, applications, or equivalent options, this device is selected for GHz-range signal integrity-critical ports where ultra-low clamping voltage (≤2.85V at 5A TLP), matched trace routing via flow-through layout, and sub-1pF loading are mandatory design requirements.
Technical Context
The RCLAMP3328P.TNT implements silicon-avalanche EPD (Electrostatic Protection Device) technology optimized for 3.3V operation, with bidirectional clamping on all eight I/O lines referenced to ground. Its flow-through pin architecture supports four differential pairs (e.g., HDMI TX0+/−, TX1+/−) without signal path skew.
Clamping performance is characterized using Transmission Line Pulse (TLP) testing (100ns pulse, 0.2ns rise), yielding ≤2.85V clamping at 5A and ≤11.8V at 16A, with dynamic resistance derived between 4A–16A TLP current steps. Junction capacitance is measured at 1MHz and 0V bias, ensuring minimal impact on 5GHz+ data lanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±30kV air, ±25kV contact - meets highest industrial ESD immunity requirement without external spark gaps. |
| Max Capacitance (I/O to GND) | 0.65pF - enables use in 5GHz+ interfaces (e.g., HDMI 1.4, USB 3.0) with negligible insertion loss. |
| Dynamic Resistance | 0.35Ω typical - minimizes voltage overshoot during fast ESD transients, improving system-level robustness. |
| Clamping Voltage (TLP, 5A) | 2.85V max - ensures protected ICs (e.g., HDMI PHY) remain below absolute maximum ratings during ESD events. |
| Working Voltage (VWM) | 3.3V - matches standard high-speed interface supply rails; prevents leakage or false triggering during normal operation. |
| Package | SGP3810N9 (3.8 × 1.0 × 0.50 mm) - surface-mount, flow-through layout supports matched differential trace lengths. |
Pinout & Package
Package: SGP3810N9 - 9-pin, lead pitch 0.4mm (intra-pair), 0.5mm (pair-to-pair), NiPdAu finish, Pb-free/RoHS compliant, tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | I/O Line A (e.g., TX0+, TX1+, etc.) | Input/output terminal for first side of differential pair; connected internally to avalanche clamp diode cathode. |
| 2, 4, 6, 8 | I/O Line B (e.g., TX0−, TX1−, etc.) | Input/output terminal for second side of differential pair; symmetric clamping to ground. |
| 9 | Ground (GND) | Common reference for all eight clamping paths; low-inductance connection critical for effective ESD energy shunting. |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through pin arrangement | Enables straight-through PCB routing for differential pairs - eliminates stubs and maintains impedance continuity (Z0 ≈ 100Ω). |
| Low dynamic resistance (0.35Ω) | Reduces clamping voltage overshoot under fast-rising ESD pulses, protecting sensitive SerDes receivers from latch-up. |
| Bidirectional ESD clamping | Protects both positive and negative ESD transients on each line without polarity constraints - simplifies layout and validation. |
| 0.65pF max I/O-to-GND capacitance | Preserves signal integrity up to 5GHz - verified via S21 insertion loss plots showing <−3dB at 5GHz. |
Applications
| HDMI 1.4 Transmitter Port | USB 3.0 SuperSpeed Interface |
|---|---|
Use Scenario: Protecting HDMI 1.4 source-side differential lanes (TX0+/− through TX2+/−) against ESD during cable hot-plug events in set-top boxes and AV receivers. IC Role / Device Role / Timing Role: ESD transient suppressor placed immediately before the HDMI connector, clamping surges before they reach the HDMI PHY. Use Value: Prevents permanent damage to HDMI transmitter ICs while maintaining eye diagram integrity at 3.4Gbps due to sub-0.7pF loading. |
Use Scenario: Shielding USB 3.0 SuperSpeed differential pairs (SSTX+/−, SSRX+/−) from ESD in docking stations and host controllers. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp integrated into the USB 3.0 signal path, co-located with connector footprint. Use Value: Enables compliance with USB-IF ESD test requirements while preserving signal rise/fall times and jitter budget at 5Gbps. |
| V-By-One HS Link | eDP Display Interface |
Use Scenario: Safeguarding V-By-One HS (up to 4Gbps per lane) differential video links in industrial displays and medical monitors. IC Role / Device Role / Timing Role: High-speed ESD protector placed at display panel input, minimizing parasitic capacitance across all 4–8 lanes. Use Value: Maintains V-By-One's strict timing margin (tskew < 0.2UI) by eliminating capacitive imbalance between +/− lines. |
Use Scenario: Protecting embedded DisplayPort (eDP) source outputs in thin-client laptops and tablets during hinge flex or connector mating. IC Role / Device Role / Timing Role: Compact 8-line ESD solution covering eDP main link lanes (AUX, HPD, and up to three differential pairs). Use Value: Achieves IEC 61000-4-2 Level 4 immunity without degrading eDP 2.7Gbps link training success rate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD8S300ARHBR | 8-channel, 0.5pF max capacitance, 3.6V working voltage, 2.7V clamping at 5A (TLP); QFN-16 package (4.0 × 4.0 mm). | Larger footprint and higher pin count; requires more PCB area and different layout routing vs. flow-through SGP3810N9. | Select when lower capacitance (<0.5pF) is prioritized over board space and differential pair symmetry. |
| SZ1.5SMC33AT3G | Discrete 33V unidirectional TVS; 1.5kW peak power; 100pF capacitance - not suitable for high-speed data lines. | Not rated for USB/HDMI/V-By-One; used only for DC power rail or low-frequency signal protection. | Reject for high-speed interface use; only applicable for non-data-line auxiliary circuit protection. |
Compared with TPD8S300ARHBR, RCLAMP3328P.TNT offers superior differential pair routing support and smaller footprint, while SZ1.5SMC33AT3G lacks the bandwidth and capacitance specs required for any GHz data interface - making RCLAMP3328P.TNT the only viable option among the three for HDMI/USB 3.0 signal line protection.

FAQ
What is the maximum operating temperature range for RCLAMP3328P.TNT?
RCLAMP3328P.TNT operates reliably from −55°C to +125°C junction temperature (TJ). This wide thermal range supports deployment in automotive infotainment head units and industrial display enclosures where ambient temperatures exceed 85°C. The device's thermal derating curve ensures sustained ESD performance across the full range without parameter drift.
Does RCLAMP3328P.TNT support bidirectional signal paths like HDMI and USB 3.0?
Yes, RCLAMP3328P.TNT provides symmetrical, bidirectional clamping on all eight I/O lines relative to ground. Each line features identical forward and reverse breakdown characteristics, enabling transparent integration into full-duplex or AC-coupled differential interfaces such as HDMI 1.4 and USB 3.0 without signal polarity restrictions.
Can RCLAMP3328P.TNT be used for PCIe Gen3 or Gen4 applications?
No - RCLAMP3328P.TNT is not recommended for PCIe Gen3 (8GT/s) or Gen4 (16GT/s). Its 0.65pF capacitance and published S21 data confirm suitability up to 5GHz, but PCIe Gen3 signaling requires tighter insertion loss and return loss control beyond this device's validated performance envelope. Use Semtech's RCLAMP0524P or discrete low-C solutions for PCIe.
What is the lead finish and RoHS status of RCLAMP3328P.TNT?
RCLAMP3328P.TNT uses NiPdAu (Nickel-Palladium-Gold) lead finish and is fully compliant with RoHS Directive 2011/65/EU and WEEE requirements. It is also halogen-free per IEC 61249-2-21, with no brominated flame retardants or chlorine-based compounds in the mold compound or terminations.
How does the flow-through package of RCLAMP3328P.TNT improve PCB layout for differential pairs?
The SGP3810N9 flow-through layout routes I/O pins 1–8 linearly (1→2, 3→4, 5→6, 7→8) with ground on pin 9, allowing differential traces to pass straight through the device without vias or bends. This preserves controlled impedance (100Ω differential), minimizes skew between +/− lanes, and reduces EMI radiation compared to L- or U-shaped routing around conventional arrays.
