Product details
Overview
RCLAMP0594P.TAT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 5V I/O or power lines in USB Type-C, USB PD, and industrial interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 6.8V (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 RCLAMP0594P.TAT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature, low capacitance (175 pF @ 5V), surge current rating (40A, 8/20μs), and compatibility with 5V bus protection in compact portable and industrial designs.
Technical Context
The RCLAMP0594P.TAT 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 (6.8V typ.) across the full 1–40A peak pulse current range due to decreasing RDS(on).
It supports unsymmetrical line protection per IEC 61000-4-5 (±1kV, 1.2/50μs, RS = 42Ω), withstands ±4kV EFT per IEC 61000-4-4, and exhibits stable junction capacitance (175 pF @ VR = 5V, f = 1MHz) and leakage (<600 nA @ VRWM) over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - defines maximum continuous operating voltage before clamping activation |
| Clamping Voltage (VC) | 6.8 V @ IPP = 24A - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold |
| Peak Pulse Current (IPP) | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD robustness standards |
| Junction Capacitance | 175 pF @ 5 V, 1 MHz - compatible with high-speed USB 2.0 data lines without signal integrity degradation |
| Dynamic Resistance | 20 mΩ - enables low-voltage clamping independent of surge magnitude |
| Operating Temperature | –40°C to +125°C - supports deployment in automotive-grade and industrial ambient environments |
Pinout & Package
Package: DFN-6, 1.6 mm × 1.6 mm × 0.55 mm, RoHS-compliant, Pb-free, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current handling and minimize inductance |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS or CC line); parallel connection ensures uniform current sharing and optimal clamping performance |
Key Features
| Feature | Design Value |
|---|---|

| Low dynamic resistance | 20 mΩ - reduces voltage overshoot during fast transients and improves energy diversion efficiency |
| High-temperature clamping stability | Clamps at 6.8V ±0.3V from –40°C to +125°C - enables reliable protection in thermally aggressive enclosures |
| Integrated FET-based protection | Replaces multi-device TVS + series resistor solutions - reduces BOM count and PCB area in space-constrained USB PD designs |
| Low leakage & capacitance | <600 nA IR @ 5V, 175 pF - preserves signal integrity on 480 Mbps USB 2.0 lines without added termination complexity |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5V VBUS lines in USB Type-C receptacles exposed to ESD and lightning-induced surges during hot-plug events. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed adjacent to connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 6.8V clamping at full 40A surge and across temperature - prevents latch-up or gate oxide damage in 5V-rated PD ICs. |
Use Scenario: Safeguarding analog sensor supply rails (e.g., 5V excitation for strain gauges or RTDs) in factory-floor PLC modules. IC Role / Device Role / Timing Role: Standalone rail protector on sensor front-end power input, absorbing induced surges from nearby motor switching or relay bounce. Use Value: Delivers ±30kV ESD immunity and 40A surge capability while adding only 175 pF loading - avoids destabilizing low-noise LDO regulation. |
| USB 2.0 Data Line (D+/D–) Protection | IoT Device Battery Charging Port Protection |
Use Scenario: ESD hardening of bidirectional USB 2.0 differential pairs in portable medical monitors or point-of-sale terminals. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor placed inline between connector and PHY, preserving signal rise/fall times. Use Value: 175 pF capacitance and <6.8V clamping ensure <1% eye diagram distortion at 480 Mbps - meets USB-IF compliance margins. |
Use Scenario: Protecting 5V input of battery management ICs in rechargeable IoT edge nodes subjected to user-handling ESD and adapter surge. IC Role / Device Role / Timing Role: First-line defense on charging input rail, diverting transients away from linear charger or buck converter input stage. Use Value: Stable 6.8V clamping prevents overvoltage shutdown or internal FET avalanche in 5V-input PMICs - extends field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-05UTG | Higher clamping voltage (12V @ 24A), higher capacitance (350 pF), same DFN-6 footprint | Designed for 12V systems; less suitable for 5V USB PD where clamping headroom is tight | Prefer RCLAMP0594P.TAT when protecting 5V rails with strict <7V clamping requirement |
| TPD4E05U06DQAR | Lower peak current (4A), lower ESD rating (±12kV), quad-channel configuration | Targeted at multi-line low-energy I/O protection (e.g., GPIO, buttons); not rated for bus-level surge | Choose RCLAMP0594P.TAT for single-line, high-energy 5V bus protection requiring 40A surge handling |
Compared with SP1003-05UTG and TPD4E05U06DQAR, RCLAMP0594P.TAT uniquely combines 40A surge rating, ±30kV ESD, and sub-7V clamping in a 5V-optimized DFN-6 package - making it the only option among the three qualified for USB PD VBUS and industrial 5V power rail hardening.

FAQ
What is the maximum continuous operating voltage for RCLAMP0594P.TAT?
The RCLAMP0594P.TAT has a reverse stand-off voltage (VRWM) of 5 V, meaning it remains non-conductive under normal operation up to this DC or RMS voltage. This makes it ideal for protecting 5V buses such as USB PD VBUS, sensor supply rails, and IoT charging inputs without leakage or loading concerns. Exceeding 5 V triggers clamping behavior per its specified breakdown and clamping characteristics.
How does RCLAMP0594P.TAT achieve stable clamping voltage across temperature?
RCLAMP0594P.TAT achieves stable clamping via a FET-based architecture: a precision trigger circuit activates a low-RDS(on) shunt FET during transients, resulting in clamping dominated by the trigger voltage rather than junction characteristics. As shown in datasheet Figure 4, RCLAMP0594P.TAT clamps at 6.8V ±0.3V from –40°C to +125°C - unlike conventional TVS diodes whose clamping rises significantly with temperature.
Can RCLAMP0594P.TAT protect USB 2.0 high-speed data lines without signal degradation?
Yes - RCLAMP0594P.TAT exhibits 175 pF junction capacitance at 5 V bias and 1 MHz, low enough to preserve USB 2.0 (480 Mbps) signal integrity when placed per layout guidelines (short traces, symmetric routing). Its constant 6.8V clamping also avoids overshoot-induced jitter or eye closure, enabling direct placement on D+/D– lines in compact USB Type-C receptacle designs.
What is the recommended PCB layout for optimal surge performance of RCLAMP0594P.TAT?
For optimal performance, place RCLAMP0594P.TAT within 3 mm of the protected connector. Connect all three GND pins (1, 2, 3) directly to a solid ground plane using ≥3 thermal vias; route all three IN pins (4, 5, 6) in parallel with identical-length traces. Avoid stubs or right-angle bends. This minimizes parasitic inductance and ensures balanced current sharing - essential to achieving the full 40A (8/20μs) rating specified for RCLAMP0594P.TAT.
Does RCLAMP0594P.TAT meet IEC 61000-4-5 surge immunity requirements?
Yes - RCLAMP0594P.TAT is rated for 40A peak pulse current (8/20μs waveform) and validated for ±1kV combination-wave surge (1.2/50μs voltage, 8/20μs current, RS = 42Ω) per IEC 61000-4-5. Its low dynamic resistance (20 mΩ) and stable clamping ensure protected downstream components remain within safe operating limits during industrial-grade surge events, making RCLAMP0594P.TAT compliant for use in Class 3 and Class 4 equipment.
