Product details
Overview
RCLAMP5031T.TNT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of 22V-rated power or I/O 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 RCLAMP5031T.TNT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for 22V bus protection in USB PD, IoT, and industrial equipment designs.
Technical Context
RCLAMP5031T.TNT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) across 24–40A peak pulse current and −40°C to +125°C operating temperature due to decreasing RDS(on) under surge conditions.
The device protects one unidirectional line with 22V working voltage (VRWM), 25–27.9V reverse breakdown (VBR), and low 130–600nA leakage at VRWM. Its functional architecture separates trigger sensing from power shunting, enabling stable clamping independent of ambient thermal rise or surge magnitude - critical for USB PD controller survivability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and ensures reliable operation without leakage or false triggering. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform) - stays below typical 30V damage threshold of USB PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial and USB PD applications. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 ESD requirements for external connectors and handheld interfaces. |
| Dynamic Resistance | 20mΩ - enables minimal voltage rise during surge conduction, directly supporting stable clamping performance. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with DC power rails and low-speed signal lines; not intended for >1Gbps data paths. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Exposed pad not present; all six terminals are signal/ground pins requiring full connection for rated surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected line input - connects directly to VBus or power rail; parallel connection of all three pins reduces trace inductance and improves ESD coupling immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across 24–40A and −40°C to +125°C - eliminates derating uncertainty in thermal or high-current environments. |
| FET-based shunt architecture | Surge-rated MOSFET + precision trigger circuit - replaces fixed-RDYN TVS diode behavior with active, low-RDS(on) conduction. |
| Low dynamic resistance | 20mΩ - ensures <1V additional drop beyond trigger voltage during 40A surge, enabling predictable protection margin. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - sustains operation under repetitive burst noise in industrial control systems. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting the VBus line of a USB Type-C receptacle handling up to 20V/5A PD negotiation and 22V fault transients. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping at full 40A surge, preventing overvoltage damage to downstream PD controllers rated ≤30V. |
Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., HS2950P) exposed to lightning-induced surges in remote meters or robotics. IC Role / Device Role / Timing Role: Primary EOS shunt device absorbing multi-kV transients before they reach the load switch's internal FET. Use Value: Clamps below the 30V absolute maximum rating of common load switch inputs, avoiding gate oxide rupture or latch-up. |
| IoT Device DC Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary power inputs on battery-backed IoT gateways subjected to ESD during field servicing or connector mating. IC Role / Device Role / Timing Role: Standalone transient suppressor on main DC input rail, upstream of DC-DC converters and PMICs. Use Value: Delivers ±30kV ESD robustness and 40A surge handling without degrading efficiency or adding significant capacitance to the rail. |
Use Scenario: Protecting 22V backup power inputs on enterprise SSDs or NAS enclosures against AC-line coupled surges during brownouts or grid switching. IC Role / Device Role / Timing Role: High-energy clamping device on secondary power path, ensuring backup supply integrity during mains disturbances. Use Value: Stable 27.5–28V clamping across temperature prevents false shutdown or data corruption in storage controllers during extended operation. |
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 | Same die, identical electrical specs, same DFN-6 package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. RCLAMP5031T.TNT's unspecified reel count). | No functional difference; validated for identical USB PD, load switch, and industrial use cases. | Select TDS2211P.C when standard Semtech reel quantity and marking (T22 + date code) are required for procurement alignment. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, but clamping rises to ~42V at 40A (per datasheet), and exhibits strong temperature dependence. | Acceptable only where clamping voltage margin >14V exists; unsuitable for tight-margin USB PD or load switch inputs. | Choose SMAJ22A only for cost-sensitive, non-critical 22V rails where clamping >40V is tolerable and thermal derating can be managed. |
Compared with RCLAMP5031T.TNT, TDS2211P.C offers identical protection performance and form factor, while SMAJ22A trades clamping stability and temperature insensitivity for lower unit cost - making RCLAMP5031T.TNT optimal for high-reliability 22V bus protection where voltage margin is constrained.

FAQ
What is the clamping voltage of RCLAMP5031T.TNT at 40A surge current?
RCLAMP5031T.TNT clamps at 27.5–28V under IEC 61000-4-5 combination waveform (1.2/50μs voltage + 8/20μs current, RS = 2Ω) at 40A peak pulse current. This value is guaranteed across −40°C to +125°C and reflects the device's FET-based architecture, which maintains near-constant clamping unlike traditional TVS diodes.
Is RCLAMP5031T.TNT pin-compatible with TDS2211P.C?
Yes, RCLAMP5031T.TNT and TDS2211P.C share identical DFN-6 pinout (Pins 1–3 = GND, Pins 4–6 = IN), mechanical dimensions (1.6mm × 1.6mm × 0.55mm), and electrical specifications. They differ only in packaging configuration and marking - making them functionally and physically interchangeable in PCB layout.
Can RCLAMP5031T.TNT be used on high-speed data lines like USB SuperSpeed?
No, RCLAMP5031T.TNT is not suitable for USB SuperSpeed (5–10Gbps) or other high-frequency data lines due to its 175pF junction capacitance, which would severely degrade signal integrity. It is designed exclusively for 22V DC power rails or low-speed control lines; for SuperSpeed lanes, Semtech recommends RClamp3371ZC (<0.25pF).
What is the maximum operating temperature range for RCLAMP5031T.TNT?
RCLAMP5031T.TNT operates reliably from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range - a key differentiator from standard TVS diodes whose clamping increases with temperature. Junction temperature may reach +150°C under surge, per absolute maximum ratings.
Does RCLAMP5031T.TNT require a thermal pad or heatsink?
No, RCLAMP5031T.TNT does not require a thermal pad or external heatsink. The device dissipates surge energy through its internal FET structure, and its DFN-6 package is designed for direct PCB copper connection. Layout best practice emphasizes low-inductance grounding via multiple vias to the ground plane - not thermal mass addition.
