Product details
Overview
RCLAMP0534N.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of single 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 7.5V (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 RCLAMP0534N.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamping architecture, low 175pF junction capacitance, 5V working voltage compatibility, and validated performance in USB PD bus protection and load switch input surge suppression.
Technical Context
RCLAMP0534N.TCT uses a surge-rated FET as the 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 across 0–24A peak pulse current due to decreasing RDS(on) under surge conditions.
The device features three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3), requiring all six pins to be connected for full 24A (8/20μs) surge handling. Its 175pF capacitance at 5V reverse bias and 130nA leakage at VRWM enable use on high-speed data lines without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - Matches standard USB 2.0/3.x and USB PD 5V bus operation without derating. |
| Clamping Voltage (VC) | 7.5 V @ IPP = 24A - Remains stable across temperature and current, protecting 5V logic interfaces below damage thresholds. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - Exceeds Level 4 immunity requirements for consumer and industrial end equipment. |
| Junction Capacitance | 175 pF @ VR = 5V, 1MHz - Low enough for USB 2.0 data lines; requires pairing with sub-0.3pF devices for SuperSpeed lanes. |
| Dynamic Resistance | 20 mΩ - Enables low-voltage drop during surge conduction, minimizing energy dissipation in protected ICs. |
| Peak Pulse Current | 24 A (tp = 8/20μs) - Meets IEC 61000-4-5 Level 3 surge immunity for industrial and USB PD applications. |
| Operating Temperature | –40°C to +125°C - Supports extended-range deployment in automotive-adjacent, industrial, and outdoor IoT systems. |
Pinout & Package
Package: DFN-6 (1.6 mm × 1.6 mm × 0.55 mm), RoHS-compliant, halogen-free, UL 94V-0 molding compound, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must be connected to PCB ground plane via multiple vias for full 24A surge capability. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBUS or CC line); shared connection ensures uniform current sharing and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.3V across 1–24A surge range, eliminating design margin inflation required with traditional TVS diodes. |
| FET-based shunt protection | Surge energy diverted through low-RDS(on) channel instead of PN-junction, reducing thermal stress and enabling higher reliability in repeated surge events. |
| Multi-pin parallel I/O | Three-input / three-ground terminal layout lowers effective package inductance and improves high-frequency transient response over single-pin alternatives. |
| Temperature-stable clamping | Clamping voltage drift <±0.1V from –40°C to +125°C, enabling robust protection in uncontrolled thermal environments without derating. |
| USB PD–optimized rating | 5V VRWM and 7.5V VC align directly with USB PD 5V default profile, supporting compliance with USB-IF ESD test plans for Type-C connectors. |
Applications
| USB Type-C VBUS Protection | USB PD Controller Input Protection |
|---|---|
Use Scenario: Protecting the 5V VBUS line of a USB Type-C receptacle against lightning-induced surges and contact ESD during hot-plug events. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed immediately adjacent to the connector, clamping transients before they reach the PD controller or load switch. Use Value: Prevents latch-up or gate oxide damage in downstream PD controllers (e.g., FUSB302, TUSB320) by limiting VBUS excursion to ≤7.5V during 24A surges. |
Use Scenario: Safeguarding the VCONN or VBUS monitoring input of a USB PD controller IC against miswiring-induced overvoltage and ESD coupling. IC Role / Device Role / Timing Role: Secondary protection device located between connector and controller analog input, operating in parallel with primary VBUS clamp. Use Value: Maintains accurate voltage sensing under transient stress by holding input node within ±0.5V of nominal 5V, avoiding false fault detection or shutdown. |
| Industrial Load Switch Input Protection | IoT Device Power Rail Clamping |
Use Scenario: Shielding the input of an industrial-grade load switch (e.g., ON Semiconductor NIS5132, TI TPS229xx) from 1kV/42Ω surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Front-end transient suppressor placed upstream of the load switch FET, absorbing surge energy before it reaches the switch's internal gate driver. Use Value: Extends load switch lifetime by preventing gate-source overvoltage and drain-source avalanche failure during repetitive surge exposure. |
Use Scenario: Securing the main 5V supply rail of battery-powered IoT edge nodes (e.g., cellular modems, sensor hubs) against ESD from user interface ports or antenna coupling. IC Role / Device Role / Timing Role: System-level rail clamp integrated into PMIC input stage, providing fail-safe protection independent of regulator control loop response. Use Value: Ensures uninterrupted operation during ±30kV ESD events by limiting rail sag and preventing brownout resets in ultra-low-power microcontrollers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| uClamp0504T.TCT | Same 5V VRWM and DFN-6 package, but uses silicon avalanche diode architecture; clamping rises to 12.5V at 24A. | Limited to lower-energy applications where 12.5V clamping is acceptable; not recommended for USB PD VBUS due to higher VC. | Select uClamp0504T.TCT only if cost sensitivity outweighs clamping performance and board space allows larger thermal relief. |
| TDS5011P | Higher 50V VRWM, 24A rating, same FET-based constant-clamp architecture; physically identical DFN-6 footprint. | Designed for 24–48V industrial buses (e.g., PoE++, CAN FD power rails); incompatible with 5V logic interfaces due to elevated breakdown. | Choose TDS5011P only when protecting >20V rails; not a functional substitute for RCLAMP0534N.TCT in 5V applications. |
Compared with uClamp0504T.TCT and TDS5011P, RCLAMP0534N.TCT uniquely combines 5V working voltage, 7.5V clamping, and FET-based constant-voltage behavior-making it the only option qualified for USB PD 5V bus protection without compromising surge margin or signal integrity.

FAQ
What is the maximum peak pulse current rating for RCLAMP0534N.TCT?
RCLAMP0534N.TCT is rated for 24A peak pulse current (tp = 8/20μs) per IEC 61000-4-5. This rating assumes all three input pins (4–6) and all three ground pins (1–3) are properly connected to minimize parasitic inductance. The device maintains 7.5V clamping at this current level, making RCLAMP0534N.TCT suitable for Level 3 industrial surge immunity requirements.
Does RCLAMP0534N.TCT support USB PD 3.0 compliance?
Yes, RCLAMP0534N.TCT supports USB PD 3.0 compliance by meeting IEC 61000-4-2 ±30kV ESD immunity and maintaining 7.5V clamping at 24A on 5V VBUS lines-within the USB-IF specified limits for Type-C connector protection. Its 175pF capacitance is compatible with USB 2.0 signaling; RCLAMP0534N.TCT must be paired with sub-0.3pF devices like RClamp3371ZC for SuperSpeed lanes.
How does RCLAMP0534N.TCT differ from standard TVS diodes in clamping behavior?
RCLAMP0534N.TCT uses a surge-rated FET and precision trigger circuit to achieve near-constant clamping voltage (7.5V ±0.2V) across 1–24A, unlike standard TVS diodes whose clamping rises linearly with current (VC = VBR + IPP × RDYN). This eliminates the need to overspecify IPP to meet voltage limits, and RCLAMP0534N.TCT maintains stable clamping from –40°C to +125°C-where conventional TVS devices degrade significantly.
Can RCLAMP0534N.TCT be used on USB SuperSpeed differential pairs?
No, RCLAMP0534N.TCT is not suitable for USB SuperSpeed (SS) TX/RX differential pairs due to its 175pF junction capacitance, which would distort high-speed signals. For SS lane protection, Semtech recommends RClamp3371ZC (0.18pF) or similar ultra-low-capacitance TVS devices. RCLAMP0534N.TCT is intended for VBUS, CC, SBU, or other low-speed 5V lines where its 175pF capacitance poses no signal integrity risk.
What PCB layout practices maximize RCLAMP0534N.TCT surge performance?
To maximize RCLAMP0534N.TCT surge performance, place it within 3mm of the protected connector, connect all three GND pins (1–3) to a solid ground plane using ≥4 vias each, route all three IN pins (4–6) via a single short, wide trace, and avoid stubs or splits in the protected line. Do not add thermal pads-energy is dissipated in the FET channel, not the die surface. These practices ensure RCLAMP0534N.TCT achieves full 24A rating and minimal clamping overshoot.
