Product details
Overview
RCLAMP0561Z.TNT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of single 5.6V I/O or power lines in USB, industrial, and IoT interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 9.8V (IPP = 24A), maintains <20mΩ dynamic resistance, and operates from –40°C to +125°C in a 1.6 × 1.6 mm DFN-6 package.
For engineers reviewing the RCLAMP0561Z.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature, low dynamic resistance under surge, junction capacitance (175 pF @ 22 V), and compatibility with USB Type-C PD bus protection where precise voltage limiting is critical.
Technical Context
The RCLAMP0561Z.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 (±0.5V) from IPP = 1A to 40A due to decreasing RDS(on) under surge stress.
It features a functional 3-pin input / 3-pin ground configuration in a monolithic DFN-6 package, with all IN pins (4–6) and GND pins (1–3) required for rated 40A (8/20µs) peak pulse current handling. Its 175 pF junction capacitance at 22V reverse bias supports robust signal integrity in DC-coupled 5.6V bus lines without excessive loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5.6 V - Maximum continuous DC operating voltage on protected line; sets upper limit for safe interface integration. |
| Clamping Voltage | 9.8 V @ IPP = 24A (1.2/50µs + 8/20µs combo wave) - Limits transient overvoltage to safe level for downstream 5.6V-rated ICs like USB PD controllers. |
| Peak Pulse Current | 40 A (tp = 8/20µs) - Withstands high-energy surges per IEC 61000-4-5; enables compliance with industrial lightning surge standards. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - Provides system-level ESD robustness without external shielding or layout reinforcement. |
| Junction Capacitance | 175 pF @ VR = 22 V, f = 1 MHz - Low enough to avoid signal distortion on moderate-speed DC-biased lines (e.g., load switch inputs, CC/SBU). |
| Dynamic Resistance | 20 mΩ (measured 1A–40A, tp = 8/20µs) - Ensures minimal IR drop during surge, enabling stable clamping independent of current magnitude. |
Pinout & Package
Package: DFN-6, 1.6 mm × 1.6 mm × 0.55 mm, RoHS-compliant, Pb-free, UL 94V-0 molding compound. Exposed thermal pad not required; energy dissipated in silicon FET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1, 2, 3 | GND | Common ground return for surge current; all three must be connected to minimize inductance and achieve full 40A rating. |
| Pin 4, 5, 6 | IN | Protected line input (e.g., VBUS, CC, SBU); parallel connection ensures uniform current sharing and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5 V across full 1–40 A surge range - eliminates need for derating at high temperatures or currents. |
| FET-based shunt topology | Replaces PN-junction TVS with low-RDS(on) MOSFET - reduces thermal stress and improves reliability under repeated transients. |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50 ns, 100 kHz & 5 kHz bursts) - protects against fast repetitive noise in industrial control environments. |
| Low leakage | 600 nA max @ 5.6 V reverse - prevents battery drain in always-on IoT sensor nodes and portable equipment. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 5.6V VBUS lines in USB-C PD ports against ESD, lightning-induced surges, and connector hot-plug transients. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector, clamping overvoltage before it reaches PD controller or load switch. Use Value: Maintains 9.8V clamping across –40°C to +125°C, preventing false trips or latch-up in wide-temperature industrial USB-C docks. |
Use Scenario: Safeguarding enable or input pins of industrial-grade load switches (e.g., HS2950P) exposed to field wiring surges. IC Role / Device Role / Timing Role: Front-end EOS protector that limits voltage seen by internal gate oxide of the load switch FET. Use Value: 40A surge rating and 20 mΩ dynamic resistance prevent damage to sensitive gate drivers during 1kV/42Ω IEC 61000-4-5 tests. |
| IoT Sensor Node Power Rail Protection | CC/SBU Line Protection in USB-C Connectors |
|
Use Scenario: Securing 5.6V supply rails in battery-powered remote sensors deployed in electrically noisy factory floors. IC Role / Device Role / Timing Role: Standalone EOS suppressor on main power input, replacing bulkier multi-stage TVS+RC solutions. Use Value: 175 pF capacitance avoids signal integrity issues on low-frequency analog sensor supplies while delivering ±30kV ESD robustness. |
Use Scenario: Protecting Configuration Channel (CC) and Sideband Use (SBU) pins in USB-C receptacles from ESD during cable insertion/removal. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor co-located with connector, handling bidirectional ±5.6V signaling. Use Value: Stable 9.8V clamping ensures CC logic thresholds (typically 0.2–2.0V) remain undisturbed during 30kV contact discharge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| uClamp2411ZA.TCT | Higher working voltage (24 V), higher clamping (27 V @ 24A), lower capacitance (12 pF) | Better suited for 20V USB PD VBUS; unsuitable for 5.6V rails due to risk of premature conduction | Select RCLAMP0561Z.TNT for 5.6V systems requiring tight clamping; uClamp2411ZA.TCT only for ≥20V interfaces. |
| TDS2211P.C | 22 V working voltage, 28 V clamping @ 40A, same DFN-6 package but larger die and higher capacitance (175 pF @ 22 V) | Designed for 22V industrial buses; incompatible with 5.6V logic due to excessive leakage and misaligned breakdown | RCLAMP0561Z.TNT is optimized for 5.6V operation; TDS2211P.C serves higher-voltage applications and is not a drop-in replacement. |
Compared with uClamp2411ZA.TCT and TDS2211P.C, RCLAMP0561Z.TNT uniquely balances low-voltage operation (5.6 V), ultra-stable clamping (9.8 V), and industrial-grade surge handling (40A) in a compact DFN-6 - making it the only validated solution for 5.6V USB-C CC/SBU and IoT power rail protection.

FAQ
What is the maximum continuous operating voltage for RCLAMP0561Z.TNT?
The RCLAMP0561Z.TNT has a reverse stand-off voltage (VRWM) of 5.6 V, meaning it is rated for continuous DC operation up to this voltage on the protected line. Exceeding 5.6 V risks premature conduction and accelerated degradation. This specification is confirmed in Semtech's official datasheet under Electrical Characteristics.
Does RCLAMP0561Z.TNT require a thermal pad on the PCB?
No, RCLAMP0561Z.TNT does not require an exposed thermal pad. Its DFN-6 package dissipates surge energy within the silicon FET structure, and Semtech's datasheet explicitly states "no thermal pad is needed." Proper grounding via all three GND pins (1–3) and short, low-inductance traces is sufficient for thermal and electrical performance.
Can RCLAMP0561Z.TNT be used to protect USB SuperSpeed differential pairs?
No, RCLAMP0561Z.TNT is not suitable for USB SuperSpeed (SS) TX/RX lines. Its 175 pF junction capacitance would severely degrade signal integrity at multi-Gbps data rates. For SS lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25 pF); RCLAMP0561Z.TNT is intended for lower-speed, DC-coupled lines such as CC, SBU, or power rails.
How does RCLAMP0561Z.TNT differ from standard TVS diodes in clamping behavior?
RCLAMP0561Z.TNT uses a triggered FET shunt instead of a PN junction, resulting in near-constant clamping voltage (9.8 V ±0.5 V) across its full 1–40 A surge range and –40°C to +125°C temperature span. Standard TVS diodes exhibit linearly rising clamping (VC = VBR + IPP × RDYN), which degrades protection margin at high current or temperature - a limitation RCLAMP0561Z.TNT eliminates.
Is RCLAMP0561Z.TNT compatible with lead-free reflow soldering processes?
Yes, RCLAMP0561Z.TNT is fully compatible with standard lead-free reflow profiles. Its DFN-6 package uses lead-free terminal finish and meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. Semtech specifies peak reflow temperature up to 260°C for 30 seconds, aligning with IPC/JEDEC Class 3 guidelines for automotive and industrial assembly.
