Product details
Overview
RCLAMP3324P.TNT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 3.3V I/O lines in USB, HDMI, and industrial interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 5.8V (IPP = 24A), maintains <0.5Ω dynamic resistance, and operates from –40°C to +125°C - enabling robust protection in space-constrained USB Type-C port designs.
For engineers reviewing the RCLAMP3324P.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature, low capacitance (12pF @ 0V), DFN-10 package compatibility with high-speed signal routing, and verified performance against IEC 61000-4-5 surge (±1kV, 1.2/50μs).
Technical Context
RCLAMP3324P.TNT uses a precision-triggered shunt FET architecture instead of conventional PN-junction TVS diodes, delivering near-constant clamping voltage independent of peak pulse current (24A–40A) and operating temperature (–40°C to +125°C). Its trigger circuit activates the low-RDS(on) FET when transient voltage exceeds VBR, bypassing surge energy to ground via three parallel input terminals.
The device integrates three independent 3.3V-rated protection channels in a single DFN-10 package, each featuring matched breakdown (5.2V typ), ultra-low leakage (<100nA @ 3.3V), and 12pF junction capacitance - optimized for bidirectional data line protection without signal integrity degradation in USB 3.2 Gen 1 and HDMI 2.0 applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 3.3V - matches standard I/O rail voltage for USB, HDMI, and PCIe interfaces without derating. |
| Clamping Voltage (VC) | 5.8V @ IPP = 24A (1.2/50μs + 8/20μs combo wave) - stays below 6V threshold of most 3.3V transceivers. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for consumer and industrial ports. |
| Junction Capacitance | 12pF @ 0V, 1MHz - enables use on 5Gbps USB 3.2 Gen 1 differential pairs with minimal insertion loss. |
| Dynamic Resistance | <0.5Ω (measured 1A–24A, tp = 8/20μs) - ensures stable clamping and minimizes voltage overshoot during fast transients. |
| Operating Temperature | –40°C to +125°C - supports operation in automotive infotainment and industrial edge gateway environments. |
Pinout & Package
Package: DFN-10 (2.5mm × 1.0mm × 0.55mm), RoHS-compliant, halogen-free, UL 94V-0 molding compound, tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | GND | Five dedicated ground terminals - reduce parasitic inductance and enable >40A surge current handling via parallel paths. |
| 6, 7, 8, 9, 10 | IN | Five input terminals - configured as three independent 3.3V protection channels (pins 6–7, 8–9, 10–GND) with shared ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS diodes with active shunt FET, achieving flat clamping response across temperature and current range. |
| Multi-channel 3.3V protection | Three independent protection paths in one DFN-10 package - reduces PCB area vs. discrete solutions and eliminates channel mismatch. |
| Low signal-line capacitance | 12pF per channel - preserves signal integrity on high-speed differential buses (USB 3.x, HDMI, DisplayPort). |
| High-energy surge rating | Rated for ±1kV (IEC 61000-4-5, 1.2/50μs + 8/20μs combo wave, RS = 42Ω) - meets industrial surge immunity standards. |
| Ultra-low leakage | <100nA @ VRWM = 3.3V - prevents DC loading on sensitive I/O pins and avoids false triggering in low-power states. |
Applications
| USB Type-C Port Protection | HDMI 2.0 Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | Quad-channel 3.3V TVS array; 12pF/channel, but clamping rises to 7.2V @ 24A (vs. 5.8V for RCLAMP3324P.TNT); uses passive PN-junction architecture. | Limited to lower-energy surges; not rated for IEC 61000-4-5 ±1kV due to higher clamping and thermal limitations. | Choose for cost-sensitive, non-surge-critical USB 2.0 applications where board space allows larger SOIC-10 package. |
| SP3222-01UTG | Single-channel 3.3V TDS; identical FET-based architecture, 5.8V clamping, but only one protection path and DFN-6 (2.0mm × 1.25mm) footprint. | Requires three separate devices for full USB Type-C auxiliary line coverage - increases BOM count and layout complexity. | Choose when protecting isolated high-value signals (e.g., single GPIO) where multi-channel integration is unnecessary. |
Compared with TPD4E05U06DQAR and SP3222-01UTG, RCLAMP3324P.TNT uniquely combines triple-channel 3.3V protection, flat 5.8V clamping across temperature and current, and DFN-10 footprint - delivering highest functional density and surge margin for USB Type-C and HDMI 2.0 designs.

FAQ
What is the maximum peak pulse current rating for RCLAMP3324P.TNT?
RCLAMP3324P.TNT is rated for 24A peak pulse current under IEC 61000-4-5 combination waveform (1.2/50μs voltage + 8/20μs current, RS = 2Ω). Its FET-based architecture sustains this rating with stable 5.8V clamping across –40°C to +125°C - unlike conventional TVS diodes whose clamping degrades with temperature.
Does RCLAMP3324P.TNT support USB 3.2 Gen 1 (5Gbps) data lines?
Yes, RCLAMP3324P.TNT supports USB 3.2 Gen 1 with 12pF junction capacitance per channel at 0V bias and minimal signal distortion. Its flat clamping response and DFN-10 layout allow placement directly at the USB Type-C connector without compromising eye diagram integrity - validated in Semtech reference designs for USB 3.x host ports.
How many independent protection channels does RCLAMP3324P.TNT provide?
RCLAMP3324P.TNT provides three independent 3.3V-rated protection channels in a single DFN-10 package. Pins 6–7, 8–9, and 10–GND form three matched paths, each with identical breakdown (5.2V typ), clamping (5.8V @ 24A), and capacitance (12pF) - eliminating inter-channel skew in multi-line interfaces like USB Type-C CC/SBU/VCONN.
Is RCLAMP3324P.TNT compliant with IEC 61000-4-2 Level 4 ESD testing?
Yes, RCLAMP3324P.TNT achieves ±30kV contact and ±30kV air discharge per IEC 61000-4-2 - exceeding Level 4 (±15kV contact / ±15kV air) requirements. This is enabled by its active FET trigger circuit and low-leakage design (<100nA @ 3.3V), ensuring no false triggering during repeated ESD events.
What is the recommended PCB layout for optimal surge performance of RCLAMP3324P.TNT?
Place RCLAMP3324P.TNT within 3mm of the protected connector. Connect all five GND pins (1–5) to a solid ground plane using ≥6 thermal vias; route all input pins (6–10) with short, symmetric traces. Avoid stubs or splits - Semtech's layout guidelines specify direct trace-to-pin routing to minimize inductance and ensure balanced current sharing across all three channels.
