Product details
Overview
UCLAMP0506P.TCT from Semtech is a transient diverting suppressor 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 17pF junction capacitance, and uses solid-state FET-based shunt architecture for stable clamping across temperature and current.
For engineers reviewing the UCLAMP0506P.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 24A surge, low 17pF capacitance for high-speed data line compatibility, DFN-6 1.6×1.6mm footprint, ±30kV ESD rating, and 5V working voltage compliance for USB 2.0/Type-C CC/SBU protection.
Technical Context
The UCLAMP0506P.TCT employs a precision-triggered surge-rated FET as its primary protection element, activated by an internal circuit when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-7.5V at both 12A and 24A-due to decreasing RDS(on) under surge conditions.
It operates over −40°C to +125°C with <600nA reverse leakage at 5V, 17pF capacitance at 1MHz/5V, and dynamic resistance of 20mΩ (8/20μs). The device is optimized for unsymmetrical line protection and meets IEC 61000-4-2, -4-4, and -4-5 standards without derating at elevated temperatures.
Key Specifications

| ±30kV ESD immunity | Meets IEC 61000-4-2 Level 4 without external spark gaps or multi-stage protection, reducing BOM count and board space. |
| Stable performance over temperature | Clamping voltage drift <0.5V from −40°C to +125°C, enabling reliable protection in uncontrolled thermal environments. |
| DFN-6 1.6×1.6mm footprint | Reduces PCB area by >50% vs. SO-8 or SOT-23 alternatives while maintaining 24A surge capability and thermal dissipation via exposed pad grounding. |
Applications
| USB Type-C CC Line Protection | Industrial 5V Sensor Interface |
|---|---|
Use Scenario: Protecting USB Type-C Configuration Channel (CC) pins against ESD events during cable insertion and hot-plug operations in portable chargers and docking stations. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between CC pin and USB PD controller, acting as first-line shunt clamp during sub-ns ESD strikes. Use Value: 7.5V clamping ensures CC logic thresholds (typically 0.2–2.0V) remain undisturbed, preventing false attach/detach detection and PD negotiation failure. |
Use Scenario: Safeguarding analog sensor outputs (e.g., 5V-output pressure or temperature transducers) connected to PLC I/O modules in factory automation systems. IC Role / Device Role / Timing Role: EOS protector on 5V analog supply or signal return path, diverting lightning-induced surges before they reach ADC front-end or op-amp input stages. Use Value: 24A peak pulse rating and −40°C to +125°C operation ensure reliability in harsh industrial settings where ambient temperature and surge exposure vary widely. |
| USB 2.0 Data Line (D+/D−) Protection | IoT Device Battery Charging Port |
Use Scenario: Shielding USB 2.0 high-speed data lines in medical handheld devices and point-of-sale terminals from ESD during frequent cable swaps. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor placed inline on D+ and D− traces, minimizing signal distortion while clamping transients to 7.5V. Use Value: 17pF capacitance avoids measurable eye diagram degradation at 480 Mbps, maintaining USB 2.0 compliance without sacrificing protection level. |
Use Scenario: Securing the 5V input of USB-C battery charging circuits in smart home hubs and asset trackers exposed to user-handled ports. IC Role / Device Role / Timing Role: Input-side surge limiter on the 5V VBUS rail entering the charging IC, preventing latch-up or gate oxide damage during plug-in surges. Use Value: Flat 7.5V clamping prevents overvoltage stress on buck converter input stages and enables use of lower-voltage-rated input capacitors and MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | Higher 12V VRWM; 12pF capacitance; ±25kV ESD; 12A IPP rating. | Better suited for 12V industrial buses but insufficient clamping margin for 5V logic interfaces. | Select only if system operating voltage ≥10V and surge requirement ≤12A; not recommended for USB CC or 5V sensor lines. |
| SP1001-01UTG | 5V VRWM; 0.5pF capacitance; ±30kV ESD; 5A IPP rating; polymer-based technology. | Ultra-low capacitance ideal for >5Gbps interfaces but lacks energy handling for IEC 61000-4-5 compliance. | Use only for ESD-only scenarios (e.g., front-panel buttons); avoid where lightning or EFT surges are present. |
Compared with TPD4E05U06DQAR and SP1001-01UTG, UCLAMP0506P.TCT uniquely balances 5V working voltage, 24A surge capability, 7.5V clamping, and 17pF capacitance-making it the only option validated for full IEC 61000-4-2/-4-5 compliance on 5V USB and industrial I/O lines without secondary protection stages.

FAQ
What is the maximum clamping voltage of UCLAMP0506P.TCT under a 24A 8/20μs surge?
The UCLAMP0506P.TCT clamps at 7.5 V under a 24A 8/20μs surge waveform per IEC 61000-4-5. This value is guaranteed across −40°C to +125°C and reflects the device's FET-based architecture, which maintains near-constant clamping voltage independent of peak current magnitude-unlike conventional TVS diodes whose clamping rises linearly with current.
Can UCLAMP0506P.TCT be used to protect USB 2.0 D+ and D− lines without degrading signal integrity?
Yes, UCLAMP0506P.TCT is qualified for USB 2.0 D+/D− protection due to its 17pF junction capacitance at 5V and 1MHz, which introduces negligible insertion loss or eye diagram distortion at 480 Mbps. Its low dynamic resistance (20mΩ) also minimizes voltage overshoot during fast ESD events, preserving signal fidelity while delivering ±30kV IEC 61000-4-2 protection.
Does UCLAMP0506P.TCT require a thermal pad or heatsink for 24A surge handling?
No, UCLAMP0506P.TCT does not require a thermal pad or external heatsink. Its DFN-6 package dissipates surge energy through the GND pins (1–3) into the PCB ground plane. Layout guidelines specify connecting all three GND pins with multiple vias to a solid internal ground layer-this provides sufficient thermal and current-carrying capacity for repeated 24A 8/20μs surges without thermal runaway or parameter shift.
How does UCLAMP0506P.TCT differ from standard TVS diodes in clamping behavior?
UCLAMP0506P.TCT uses a triggered FET shunt instead of a pn-junction avalanche structure. As a result, its clamping voltage remains stable at ~7.5V from 1A to 24A and from −40°C to +125°C. In contrast, standard TVS diodes exhibit rising clamping (VC = VBR + IPP × RDYN) with both current and temperature-often exceeding safe limits for 5V logic at elevated ambient temperatures or high surge currents.
Is UCLAMP0506P.TCT compatible with automated SMT assembly processes?
Yes, UCLAMP0506P.TCT is fully compatible with standard reflow soldering profiles (J-STD-020 compliant), including peak temperatures up to 260°C. Its DFN-6 package has well-defined land patterns, lead-free terminations, and no moisture sensitivity level (MSL) restrictions-enabling reliable placement and soldering in high-volume manufacturing without special baking or handling requirements.
