Product details
Overview
RCLAMP3324T.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of 22V-rated power or data lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the RCLAMP3324T.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC vs. IPP behavior, DFN-6 package layout constraints, and compatibility with 22V bus systems requiring robust surge immunity per IEC 61000-4-5.
Technical Context
RCLAMP3324T.TCT implements a surge-rated FET shunt architecture with precision trigger circuitry - unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A and across –40°C to +125°C due to decreasing RDS(on) under surge conditions. It operates as a voltage-controlled switch activated above VBR ≈ 27.9V.
The device protects one bidirectional line (pins 4–6 to pins 1–3), with all six terminals electrically grouped into two functional sets: three GND pins (1,2,3) and three IN pins (4,5,6). Its solid-state design eliminates junction heating limitations typical of avalanche diodes, enabling stable energy handling up to 1120W peak pulse power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS=42Ω) on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements for connector-facing protection. |
| Dynamic Resistance | 20mΩ - enables flat clamping response; reduces voltage overshoot during fast-rising transients compared to TVS diodes with fixed RDYN. |
| Junction Capacitance | 175pF at 22V, 1MHz - suitable for <20Mbps signal lines (e.g., USB 2.0, SMBus, PMBus); not intended for USB 3.x/PCIe. |
| Operating Temp | –40°C to +125°C - maintains specified clamping and leakage performance across full industrial temperature range. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound, tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected with low-inductance routing to maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected line input (bidirectional); tied together externally to interface with VBUS, CC, or load switch input - no internal series impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A and remains stable across –40°C to +125°C - eliminates derating uncertainty in thermal designs. |
| FET-based shunt protection | Uses surge-rated MOSFET instead of PN-junction - dissipates energy in channel rather than junction, avoiding thermal runaway and enabling higher IPP density. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - minimizes IR drop during surge, delivering tighter clamping control than TVS diodes (RDYN > 1Ω). |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive switching noise in motor drives and industrial PLCs. |
| Space-efficient footprint | 1.6mm × 1.6mm DFN-6 saves >60% board area vs. SO-8 or SOT-23 TVS solutions rated for equivalent 40A surge. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to ESD from hot-plug events and lightning-induced surges on long cables. IC Role / Device Role: Primary high-energy shunt clamp placed directly at connector, upstream of PD controller and load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to 24V-tolerant PD controllers (e.g., TUSB73x, STUSB4500) where standard TVS would exceed 35V at elevated temperature. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., ON Semi NIS5132, TI TPS25940) in remote meters, robotics, and factory automation equipment. IC Role / Device Role: Transient shunt placed between VIN and GND before the load switch's internal FET, limiting gate-source and drain-source overvoltage during surge events. Use Value: Clamps to ≤28V during 40A transients - keeps stress below 30V absolute maximum ratings of integrated e-fuse FETs, preventing latch-up or permanent failure. |
| IoT Edge Node Power Bus Protection | Storage Device 12–24V Rail Protection |
|
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways and edge AI nodes subjected to ESD during field servicing and conducted surges from shared AC adapters. IC Role / Device Role: Single-component solution for 22V rail protection - replaces multi-stage TVS+MOV or TVS+polymer PTC combinations. Use Value: Delivers 40A surge handling and ±30kV ESD in 1.6mm² footprint - enables compact, reliable protection without thermal management overhead or PCB real estate penalty. |
Use Scenario: Protecting 24V input rails of NVMe SSD enclosures, SAS backplanes, and enterprise HDD trays exposed to hot-swap transients and system-level ESD coupling. IC Role / Device Role: Front-end clamp on main power input, coordinated with downstream low-capacitance TVS (e.g., RClamp3371ZC) on data lanes. Use Value: 175pF capacitance avoids signal integrity impact on 24V bias rails while providing certified IEC 61000-4-5 Level 4 immunity - meets storage OEM reliability test plans. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Identical electrical specs, same DFN-6 package, identical pinout (GND on 1–3, IN on 4–6), but marked "T22" and shipped in 3,000-unit reels. | Same use cases: USB-C PD, load switch input, 22V rail protection - validated in Semtech reference designs for Type-C and industrial e-fuses. | Select TDS2211P.C when sourcing from Semtech's official distribution channel with full traceability and guaranteed revision (Rev 2.5). |
| SP1003-02HTG | TVS diode array (SOD-323), 22V VRWM, 33V VC @ 24A, 350pF - higher clamping, higher capacitance, no constant-clamp behavior. | Suitable only for lower-speed, lower-energy applications (e.g., 5V logic lines); cannot replace RCLAMP3324T.TCT in 40A/22V PD or load switch roles. | Consider SP1003-02HTG only if cost sensitivity outweighs clamping performance and board space is unconstrained - not a functional substitute. |
Compared with TDS2211P.C, RCLAMP3324T.TCT shares identical electrical behavior and mechanical form, differing only in marking and reel packaging; versus SP1003-02HTG, it delivers 6V lower clamping, 50% less capacitance, and thermally stable performance - making it the sole viable option for 22V high-reliability power rail protection.

FAQ
What is the exact pin configuration and connection requirement for RCLAMP3324T.TCT?
RCLAMP3324T.TCT uses a 6-pin DFN package with pins 1–3 assigned to GND and pins 4–6 assigned to IN. All three GND pins must be connected to a low-inductance ground plane, and all three IN pins must be tied together externally to the protected line - splitting or omitting any pin degrades peak pulse current capability below 40A.
Does RCLAMP3324T.TCT meet IEC 61000-4-5 Level 4 surge immunity?
Yes, RCLAMP3324T.TCT is rated for ±1kV (1.2/50μs voltage, 8/20μs current, RS=42Ω) on unsymmetrical lines per IEC 61000-4-5, supported by its 40A peak pulse current rating and 27.5–28V clamping voltage - verified in Semtech's TDS2211P reference design documentation which applies identically to RCLAMP3324T.TCT.
How does RCLAMP3324T.TCT differ from standard TVS diodes in clamping behavior?
RCLAMP3324T.TCT uses a triggered FET shunt architecture that maintains near-constant clamping voltage (27.5–28V) from 24A to 40A and across –40°C to +125°C, whereas standard TVS diodes exhibit linear VC = VBR + IPP × RDYN rise - causing clamping to exceed 35V at high current or temperature, risking damage to 24V-rated ICs.
Can RCLAMP3324T.TCT be used on high-speed data lines like USB 3.2 or PCIe?
No, RCLAMP3324T.TCT is not suitable for high-speed data lines - its 175pF junction capacitance introduces excessive signal loading and insertion loss on >1Gbps interfaces. It is designed exclusively for 22V power rails and low-speed control lines (e.g., USB PD CC, load switch EN); use RClamp3371ZC (<0.25pF) for SuperSpeed lanes.
Is RCLAMP3324T.TCT RoHS and REACH compliant?
Yes, RCLAMP3324T.TCT is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 - confirmed in Semtech's official datasheet Rev 2.5, Section "Mechanical Characteristics", and supported by material declarations available through Semtech's compliance portal.
