Product details
Overview
RCLAMP2654P.TCT from Semtech is a low-capacitance TVS array designed for ESD and surge protection of USB 2.0, USB OTG, and micro-USB interfaces. It integrates dedicated protection for DP, DM, and ID lines (4 V rated) plus a high-surge VBus clamp (26 V), with <0.80 pF capacitance on data lines, ±15 kV IEC 61000-4-2 contact ESD rating, and 80 A (8/20 µs) VBus surge capability.
For engineers reviewing the RCLAMP2654P.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include its SLP2626P10 10-pin package, differential data-line clamping voltage of 8.5 V at 1 A, VBus clamping voltage of 35 V at 80 A, dynamic resistance of 0.55 Ω on DP/DM/ID, and compliance with IEC 61000-4-2/4-4/4-5 across all protected pins.
Technical Context
The RCLAMP2654P.TCT implements dual-stage protection: three parallel 4 V TVS diodes (pins 4–6) safeguard DP, DM, and ID signal lines up to 4 V operating voltage, while three shorted 26 V TVS diodes (pins 1–3) protect the VBus line with 28 V minimum breakdown at 1 mA. All protected paths reference the exposed thermal pad (pin Tab) as system ground.
Its solid-state silicon-avalanche architecture delivers extremely low dynamic resistance (0.55 Ω typical on signal pins) and sub-0.80 pF junction capacitance-critical for preserving USB 2.0 signal integrity at 480 Mbps. The device requires PCB-level shorting of pins 1–3 to achieve full 80 A surge rating on VBus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signal Line Clamping Voltage | 8.5 V at 1 A IPP - ensures safe voltage stress on USB transceivers during ESD events |
| VBus Clamping Voltage | 35 V at 80 A IPP - limits VBus overvoltage during lightning-surge transients |
| Data Line Capacitance | <0.80 pF at 0 V - preserves USB 2.0 eye diagram integrity and minimizes signal distortion |
| ESD Rating (IEC 61000-4-2) | ±15 kV contact on DP/DM/ID; ±30 kV contact on VBus - exceeds industrial immunity requirements |
| Dynamic Resistance | 0.55 Ω typical on DP/DM/ID - reduces clamping voltage overshoot under fast transients |
| Surge Rating (IEC 61000-4-5) | 80 A (8/20 µs) on VBus - withstands severe lightning-induced surges in portable systems |
| Operating Voltage | 4 V max on DP/DM/ID; 26 V max on VBus - matches USB specification voltage domains |
Pinout & Package
The RCLAMP2654P.TCT is housed in a 2.6 × 2.6 × 0.60 mm SLP2626P10 leadless package with an exposed thermal pad (Tab) serving as the primary ground terminal. Pins 1–3 must be shorted externally on PCB to enable full VBus surge rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | VBus Surge Protection Anode | Shorted inputs for 26 V TVS; require PCB copper short to achieve 80 A rating |
| Pin 4 | DP Line Protection Cathode | Connected to USB DP; clamps to GND when voltage exceeds 4 V |
| Pin 5 | DM Line Protection Cathode | Connected to USB DM; symmetric clamping with Pin 4 for differential integrity |
| Pin 6 | ID Line Protection Cathode | Supports USB OTG role detection; same 4 V clamping threshold as DP/DM |
| Tab (exposed pad) | System Ground Reference | Primary low-inductance GND path; multiple microvias recommended for ESD performance |
| Pins 7–10 | No Connect (NC) | Unbonded; must remain unconnected per datasheet layout guidance |
Key Features
| Feature | Design Value |
|---|---|
| Low signal-line capacitance | <0.80 pF enables USB 2.0 high-speed (480 Mbps) operation without signal degradation |
| Dual-voltage protection architecture | Separate 4 V (DP/DM/ID) and 26 V (VBus) clamping thresholds match native USB voltage domains |
| Integrated VBus surge handling | 80 A (8/20 µs) rating eliminates need for external high-current TVS on power rail |
| Ultra-low dynamic resistance | 0.55 Ω typical on data lines reduces transient-induced voltage overshoot at IC input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB interface protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-01WTG | Single-channel 0.3 pF TVS; requires 3× devices for DP/DM/ID + separate VBus TVS | Lacks integrated VBus protection; higher BOM count and board area | Choose only if ultra-low capacitance (<0.3 pF) is prioritized over integration and VBus surge rating |
| TPD2EUSB30DRBR | 0.7 pF typical capacitance; 5.5 V working voltage on data lines; no integrated VBus TVS | Designed for USB 3.0; lacks VBus surge capability-requires external 26 V TVS | Select for USB 3.0 SuperSpeed designs; not suitable for VBus-only surge protection needs |
Compared with SP1006-01WTG and TPD2EUSB30DRBR, the RCLAMP2654P.TCT uniquely combines full USB 2.0 signal-line protection (DP/DM/ID) and high-current VBus clamping in one SLP2626P10 package-reducing component count, PCB area, and ground-path inductance versus multi-device solutions.

FAQ
What is the maximum operating voltage supported by RCLAMP2654P.TCT on USB data lines?
The RCLAMP2654P.TCT supports a maximum operating voltage of 4 V on DP, DM, and ID pins. This is defined by its 4 V standoff voltage (VWM)-ensuring reliable non-conduction during normal USB 2.0 signaling while triggering clamping above that threshold. Exceeding 4 V continuously risks premature conduction and potential device degradation.
Why must pins 1, 2, and 3 of RCLAMP2654P.TCT be shorted on the PCB?
Pins 1, 2, and 3 are internally connected to the anode of the same 26 V VBus TVS structure. Shorting them externally on the PCB ensures current sharing across all three terminals during surge events, enabling the full 80 A (8/20 µs) IEC 61000-4-5 rating. Leaving them unshorted reduces effective surge current handling and compromises protection reliability.
Does RCLAMP2654P.TCT provide ESD protection for both air and contact discharge per IEC 61000-4-2?
Yes, the RCLAMP2654P.TCT provides ±30 kV ESD protection on VBus pins (1–3) and ±18 kV air / ±15 kV contact discharge on DP/DM/ID pins (4–6), fully compliant with IEC 61000-4-2. These ratings are verified per standard test conditions and apply directly to the RCLAMP2654P.TCT device as specified in its preliminary datasheet.
What is the thermal pad (Tab) connection requirement for RCLAMP2654P.TCT?
The exposed thermal pad (Tab) of the RCLAMP2654P.TCT must be soldered to a solid PCB ground plane using multiple microvias. This establishes the lowest-inductance return path for ESD/surge currents, minimizing clamping voltage overshoot. Failure to properly connect the Tab degrades ESD performance and violates the device's validated test configuration.
Can RCLAMP2654P.TCT be used in USB 3.0 applications?
No, the RCLAMP2654P.TCT is specifically characterized and optimized for USB 2.0 (480 Mbps) interfaces. Its capacitance profile and clamping behavior are validated for 2.0 signaling frequencies. For USB 3.0 SuperSpeed (5 Gbps), Semtech recommends devices like the TPD2EUSB30 series, which offer lower capacitance and differential pair tuning not present in the RCLAMP2654P.TCT.
