Product details
Overview
RCLAMP3328P.TZT from Semtech is an 8-line low-capacitance ESD protection 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 3.8 × 1.0 × 0.50 mm SGP3810N9 package.
For engineers reviewing the RCLAMP3328P.TZT datasheet, pinout, applications, or equivalent options, this device is selected for ultra-low signal distortion in >5 GHz data paths, minimal clamping voltage under TLP stress, and flow-through PCB layout compatibility with matched trace lengths for differential pairs.
Technical Context
The RCLAMP3328P.TZT uses silicon-avalanche EPD technology optimized for 3.3 V operation, enabling sub-3 V clamping at 5 A (8/20 µs) per IEC 61000-4-5 and low-leakage reverse standoff of 3.3 V. Its symmetrical bidirectional structure supports both positive and negative ESD transients without polarity constraints.
Designed specifically for high-speed serial links, it integrates eight independent protection channels-four differential pairs-with intra-pair pitch of 0.40 mm and pair-to-pair pitch of 0.50 mm. The flow-through architecture routes I/O pins linearly across the package to preserve impedance continuity and reduce stub length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 7, 8 | I/O Channel (Differential Pair Terminals) | Eight independent ESD protection paths - pins 1–2, 4–5, 7–8 form three differential pairs; pin 3 is GND for first pair, pin 6 is GND for second, pin 9 is GND for third |
| 3, 6, 9 | Ground Return (Per-Pair) | Dedicated local ground terminals per differential pair - enables low-inductance return path and minimizes crosstalk between protected lanes |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD8S300APWPR | 8-channel, 0.5 pF max capacitance, 3.6 V working voltage, 0.5 Ω dynamic resistance, 10-pin UQFN | Higher working voltage margin but larger 2.5 × 1.0 mm package; no flow-through pinout | Preferred where higher VRW (3.6 V) is required or where board space permits larger footprint |
| SP3222-04UTG | 4-channel, 0.35 pF max, 3.3 V, 0.5 Ω, 10-pin µDFN; requires two devices for 8-line coverage | Lower capacitance but dual-device solution increases BOM count and layout complexity | Selected when lowest possible capacitance (<0.4 pF) is mandatory for >6 GHz applications |
Compared with TPD8S300APWPR and SP3222-04UTG, the RCLAMP3328P.TZT offers optimal balance of ultra-low capacitance, flow-through routing, and single-package 8-line integration - making it the preferred choice for space-constrained HDMI, USB 3.0, and V-By-One designs requiring minimal signal impact.

FAQ
What is the maximum operating voltage rating for RCLAMP3328P.TZT?
The RCLAMP3328P.TZT has a maximum working voltage (VRWM) of 3.3 V, verified per its electrical characteristics table. This rating ensures reliable operation across standard 3.3 V high-speed interface rails such as HDMI, USB 3.0, and V-By-One without leakage or premature conduction. The device remains fully functional within –40°C to +125°C ambient conditions while maintaining this voltage threshold.
Does RCLAMP3328P.TZT support bidirectional ESD protection?
Yes, RCLAMP3328P.TZT provides symmetrical bidirectional clamping, with identical clamping voltage performance for both positive and negative ESD transients. Measured TLP curves show 2.5 V clamping at +5 A and 2.8 V at –5 A, confirming balanced behavior essential for AC-coupled differential signaling like HDMI and USB 3.0 where polarity is undefined.
What is the significance of the SGP3810N9 package's flow-through design in RCLAMP3328P.TZT?
The flow-through design of the SGP3810N9 package in RCLAMP3328P.TZT positions I/O pins linearly across the device (e.g., Pin 1 → Pin 2 → Pin 3-GND), enabling straight PCB trace routing for differential pairs. This eliminates stubs and discontinuities, preserving characteristic impedance and minimizing reflections - a critical advantage over L-shaped or folded layouts in >3 Gbps applications.
How does RCLAMP3328P.TZT achieve 0.65 pF capacitance while delivering ±25 kV ESD protection?
RCLAMP3328P.TZT achieves 0.65 pF max I/O-to-ground capacitance through Semtech's proprietary low-voltage EPD silicon-avalanche process, which optimizes junction area and doping profiles. This process enables high ESD withstand without increasing parasitic capacitance - unlike conventional TVS diodes - allowing simultaneous compliance with IEC 61000-4-2 Level 4 and 5 GHz signal integrity requirements.
Can RCLAMP3328P.TZT be used in eDP v1.4 applications?
Yes, RCLAMP3328P.TZT is qualified for eDP v1.4 applications. Its 2.8 V clamping voltage at 5 A stays well within the eDP receiver's absolute maximum rating of VDD + 0.5 V (typically ≤ 3.8 V), and its 0.65 pF capacitance meets the ≤ 0.8 pF requirement for main link lanes. Layout guidelines in Semtech's application notes confirm successful integration on eDP flex cables and panel-edge connectors.
