Product details
Overview
UCLAMP0506T.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of 5V I/O or power lines in USB, industrial, and IoT interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 7.5V (IPP = 24A), features 0.5pF junction capacitance, and uses a surge-rated FET architecture to maintain stable clamping across temperature and current. It protects single-line applications such as USB Type-C CC/SBU or load switch inputs.
For engineers reviewing the UCLAMP0506T.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 24–40A surges, sub-1pF capacitance for high-speed signal integrity, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 standards.
Technical Context
The UCLAMP0506T.TCT employs a precision-triggered shunt FET architecture - not a conventional TVS diode - enabling near-constant clamping voltage (7.5V typ. at 24A) independent of peak pulse current and operating temperature (−40°C to +125°C). Its dynamic resistance is 18mΩ, ensuring minimal voltage rise during surge conduction.
It integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3) in a 1.6mm × 1.6mm DFN package, requiring all six pins to be connected for full 40A (8/20μs) surge rating. The device operates with 5V working voltage (VRWM = 5V), reverse leakage <100nA at VRWM, and junction capacitance of 0.5pF at 0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - defines maximum continuous DC bus voltage before clamping activation; matches standard 5V USB, logic, and sensor interfaces. |
| Clamping Voltage (VC) | 7.5 V at IPP = 24A (1.2/50μs + 8/20μs combo wave) - ensures protected ICs (e.g., USB PD controllers, load switches) remain below absolute max ratings during surge events. |
| Junction Capacitance (CJ) | 0.5 pF at 0V - enables use on high-speed data lines (CC, SBU, I²C) without signal distortion or bandwidth degradation. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for consumer and industrial end-equipment. |
| Peak Pulse Current (IPP) | 40 A (8/20μs) - supports robust protection against lightning-induced surges per IEC 61000-4-5, including ±1kV unsymmetrical line tests. |
| Dynamic Resistance (RDYN) | 18 mΩ - low ON-resistance of internal shunt FET minimizes IR drop during surge, stabilizing clamping performance across current range. |
Pinout & Package
UCLAMP0506T.TCT is housed in a RoHS-compliant, halogen-free DFN-6 package measuring 1.6 mm × 1.6 mm × 0.55 mm, with exposed thermal pad (no solder required) and UL 94V-0 molding compound. All six terminals must be connected: pins 1–3 serve as dedicated ground return paths, and pins 4–6 form a low-inductance, parallel-connected input node for optimal surge current sharing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground (GND) | Three parallel low-inductance GND connections - mandatory for achieving full 40A surge rating and minimizing ground bounce during fast transients. |
| Pins 4, 5, 6 | Input (IN) | Three parallel surge input terminals - connect directly to protected line (e.g., USB CC, SBU, or load switch VIN); shared node ensures uniform current division and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Replaces traditional TVS diodes with a triggered shunt FET, delivering flat clamping voltage (±0.2V variation) across −40°C to +125°C and 1–40A surge range. |
| Ultra-low junction capacitance | 0.5 pF enables placement on high-speed, noise-sensitive lines (e.g., USB Type-C CC, SBU, I²C) without degrading signal integrity or timing margins. |
| Triple-terminal input & ground | Three parallel IN and three parallel GND pins reduce trace inductance by >50% vs. single-pin alternatives, improving response to sub-ns ESD events. |
| High-energy surge handling | Rated for 40A (8/20μs) and ±1kV (1.2/50μs + 8/20μs combo wave, RS = 42Ω), meeting industrial surge immunity requirements without external series impedance. |
Applications
| USB Type-C CC/SBU Line Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting USB Type-C Configuration Channel (CC) and Sideband Use (SBU) lines from ESD and EOS events during hot-plug or cable insertion. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector, clamping surges before they reach USB PD controller or multiplexer. Use Value: 0.5pF capacitance prevents signal jitter on CC/SBU; 7.5V clamping ensures PD controller VDDIO (typically 5V) remains within safe operating limits during ±30kV ESD strikes. |
Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., TPS229xx, AP2265x) against lightning-induced surges in remote meters or factory automation nodes. IC Role / Device Role / Timing Role: Primary front-end surge protector on VIN rail, absorbing energy before it reaches the load switch's internal MOSFET gate oxide. Use Value: 40A surge rating and 18mΩ RDYN prevent voltage overshoot beyond the load switch's absolute maximum VIN rating (often 5.5–6.5V), avoiding catastrophic failure. |
| IoT Sensor Interface Protection | Smartphone Peripheral Port Protection |
|
Use Scenario: Shielding 5V I²C, UART, or GPIO lines connecting microcontrollers to environmental sensors (e.g., temperature, humidity) in unshielded enclosures. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on bidirectional signal lines, preserving rise/fall times while blocking EOS from EMI-coupled cables or human touch. Use Value: Sub-1pF capacitance maintains >10 MHz signal bandwidth; ±30kV ESD rating meets IEC 61000-4-2 Level 4 for handheld field-deployed devices. |
Use Scenario: Protecting auxiliary ports (e.g., SIM tray detection, antenna tuning, or charging indicator lines) in smartphones and tablets exposed to repeated ESD during user interaction. IC Role / Device Role / Timing Role: Miniature, board-level ESD clamp mounted adjacent to port connectors, activated within nanoseconds of transient onset. Use Value: 1.6mm × 1.6mm footprint saves critical PCB area; 7.5V clamping prevents latch-up or gate oxide damage in baseband PMICs interfacing with these low-voltage control lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-050 | TVS diode (not FET-based); higher clamping (12V at 24A), 12pF capacitance, 30kV ESD rating. | Suitable for lower-speed, non-data lines (e.g., power enable, reset); not recommended for CC/SBU due to capacitance-induced signal distortion. | Select SP1003-050 only when board space allows larger SOD-323 package and signal bandwidth is <1MHz. |
| uClamp0506T | Same Semtech FET-based architecture; identical pinout and electrical specs, but lacks tape-and-reel packaging code (.TCT) and may have different date-code marking. | Functionally interchangeable in design; verified drop-in replacement per Semtech documentation and distributor cross-reference. | Prefer uClamp0506T for prototyping or small-batch builds where reel packaging is not required; UCLAMP0506T.TCT preferred for automated SMT production. |
Compared with SP1003-050, UCLAMP0506T.TCT offers 24× lower capacitance and 4.5V lower clamping - critical for high-speed interfaces - while uClamp0506T provides identical protection performance with simplified logistics for non-reel applications.

FAQ
What is the maximum continuous operating voltage for UCLAMP0506T.TCT?
The UCLAMP0506T.TCT has a reverse stand-off voltage (VRWM) of 5 V, meaning it can safely operate on DC or low-frequency signal lines up to 5 V without triggering. This makes it ideal for protecting 5V USB, I²C, and GPIO interfaces. Exceeding 5 V continuously risks premature conduction and accelerated wear. UCLAMP0506T.TCT is rated for transient clamping only - sustained overvoltage requires upstream regulation.
How does UCLAMP0506T.TCT differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), UCLAMP0506T.TCT uses a triggered shunt FET that maintains ~7.5 V clamping from 1A to 40A and across −40°C to +125°C. This stability prevents downstream ICs from exceeding absolute maximum ratings under varying surge conditions - a key advantage confirmed in Semtech's TDS2211P reference data, which shares the same architecture.
Can UCLAMP0506T.TCT be used on USB SuperSpeed differential pairs?
No - UCLAMP0506T.TCT is not intended for USB 3.x TX/RX or PCIe lanes. Its 0.5 pF capacitance is optimized for single-ended lines like CC, SBU, or power rails. For SuperSpeed lines, Semtech recommends RClamp3371ZC (0.15 pF) or similar sub-0.2 pF devices. Using UCLAMP0506T.TCT on differential high-speed pairs would cause impedance mismatch and bit-error-rate degradation.
What is the recommended PCB layout for UCLAMP0506T.TCT to achieve full 40A surge rating?
To achieve the full 40A (8/20μs) rating, all three GND pins (1–3) and all three IN pins (4–6) must be connected with short, wide traces and multiple vias to an inner ground plane. Place UCLAMP0506T.TCT within 3 mm of the protected connector. Avoid stubs or tees on the IN trace. Semtech's layout guidelines emphasize symmetric routing and minimized loop inductance - deviations reduce effective surge current handling and increase clamping voltage overshoot.
Is UCLAMP0506T.TCT compliant with automotive AEC-Q200?
No - UCLAMP0506T.TCT is not AEC-Q200 qualified. It is rated for industrial temperature range (−40°C to +125°C) and meets IEC 61000-4-2/4-4/4-5, but lacks the stress testing, failure analysis, and qualification documentation required for automotive applications. For AEC-Q200-compliant 5V transient protection, consider Semtech's AEC-Q200-qualified TDS5V0F1B or equivalent alternatives.
