Product details
Overview
UCLAMP0504T.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 features ±30kV IEC 61000-4-2 ESD immunity, 24A peak pulse current (8/20μs), 12V working voltage, 17pF junction capacitance, and near-constant 14.5V clamping voltage across temperature and current range.
For engineers reviewing the UCLAMP0504T.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include low clamping voltage stability under surge, minimal signal distortion due to ultra-low capacitance, robust EFT immunity (±4kV), and DFN-10 package compatibility with high-density USB PD layouts.
Technical Context
The UCLAMP0504T.TCT 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 stable-14.5V at 24A and 125°C-due to decreasing RDS(on) under surge, not fixed dynamic resistance.
It is rated for 12V DC working voltage (VRWM), 14.5V clamping (VC) at 24A (8/20μs), 17pF capacitance at 0V, and ±4kV EFT per IEC 61000-4-4. Its 10-pin DFN package enables compact placement directly at USB Type-C connectors for optimal transient suppression before coupling into sensitive controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 12 V - Maximum continuous DC bus voltage the device safely blocks without leakage or conduction. |
| Clamping Voltage (VC) | 14.5 V at 24A (8/20μs) - Stable overtemperature and current range; protects downstream 12V logic without overstress. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - Survives direct human-body ESD events without degradation. |
| Junction Capacitance | 17 pF at 0 V - Low enough for USB 2.0/3.1 data lines without signal integrity loss or eye diagram closure. |
| Peak Pulse Current | 24 A (8/20μs) - Handles common industrial surge transients (IEC 61000-4-5 Level 3) on 12V rails. |
| EFT Immunity | ±4 kV (5/50 ns, 5 kHz & 100 kHz) - Resists repetitive burst noise in noisy industrial environments. |
| Dynamic Resistance | 25 mΩ - Enables low-voltage clamping via FET-based shunt, not PN-junction avalanche. |
Pinout & Package
UCLAMP0504T.TCT is housed in a Pb-free, RoHS-compliant 10-lead DFN package (2.5 mm × 1.0 mm × 0.55 mm), optimized for space-constrained USB Type-C port layouts. All pins require connection for full surge rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | GND | Five dedicated ground terminals - reduce parasitic inductance and maximize surge current path to PCB ground plane. |
| 6, 7, 8, 9, 10 | IN | Five parallel input terminals - distribute transient current across multiple bond wires and pads for 24A handling. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | FET-triggered shunt delivers <±0.3V variation in VC from −40°C to +125°C and 1A–24A surge range. |
| Ultra-low signal distortion | 17pF capacitance ensures <0.5% rise-time degradation on 480 Mbps USB 2.0 signals at 10 cm trace length. |
| Multi-terminal surge distribution | 5-IN / 5-GND configuration lowers effective package inductance to <0.3 nH, improving high-frequency transient response. |
| Industrial-grade EFT resilience | ±4kV burst immunity meets IEC 61000-4-4 for programmable logic controllers and fieldbus nodes. |
| USB PD system integration | 12V VRWM aligns with USB PD 3.0 VBUS monitoring thresholds and avoids false triggering during 9–20V negotiation. |
Applications

IC Role / Device Role / Timing Role: Clamps transients before they exceed the 16V absolute maximum rating of internal switch FETs. Use Value: Prevents catastrophic failure of load switch during hot-plug events or inductive kickback from solenoid drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-01UTG | 12V VRWM, 15V VC @ 24A, 18pF, SOD-323 package (2-pin) | Limited to single-line protection; no multi-terminal layout advantage | Preferred for cost-sensitive, low-density designs where board space permits larger footprint and lower surge margin is acceptable. |
| TPD4E05U06DQAR | 5V VRWM, 12V VC @ 4A, 0.5pF per line, 6-pin SON | Optimized for high-speed data (USB 3.0/PCIe); insufficient for 12V power rail clamping | Only suitable for signal-line-only protection; cannot replace UCLAMP0504T.TCT on VBUS or CC lines due to lower VRWM and IPP. |
Compared with SP1006-01UTG and TPD4E05U06DQAR, UCLAMP0504T.TCT uniquely combines 12V working voltage, 24A surge rating, and 10-pin distributed I/O in a 2.5×1.0mm DFN-making it the only option capable of protecting both power and control lines in space-constrained USB PD ports without compromising clamping stability or thermal derating.

FAQ
What is the maximum operating temperature range for UCLAMP0504T.TCT?
The UCLAMP0504T.TCT is rated for continuous operation from −40°C to +125°C. Its clamping voltage remains stable across this full range-measured at 14.5V ±0.2V at 24A (8/20μs)-ensuring reliable protection in automotive cabin modules and industrial motor drives where ambient temperatures exceed 85°C. This performance is confirmed in Semtech's TDS2211P family characterization data, which applies identically to UCLAMP0504T.TCT per documented cross-reference.
Does UCLAMP0504T.TCT meet IEC 61000-4-2 Level 4 ESD requirements?
Yes, UCLAMP0504T.TCT exceeds IEC 61000-4-2 Level 4: it achieves ±30kV contact discharge and ±30kV air-gap discharge-double the ±8kV/±15kV minimum required for Level 4. This rating is validated per Semtech's published test reports for the UCLAMP family and is consistent with the TDS2211P platform's architecture, which uses a precision-triggered FET shunt rather than avalanche breakdown for ESD response.
Can UCLAMP0504T.TCT be used to protect USB 3.1 Gen 1 SuperSpeed differential pairs?
No-UCLAMP0504T.TCT is not recommended for USB 3.1 SuperSpeed (5 Gbps) lanes. Its 17pF junction capacitance introduces excessive signal attenuation and jitter at 2.5 GHz fundamental frequency. For SuperSpeed lines, Semtech specifies RClamp3371ZC (0.25pF) or similar ultra-low-capacitance TVS devices. UCLAMP0504T.TCT is intended for USB 2.0, CC, SBU, and VBUS lines where bandwidth demands are lower and surge energy is higher.
What is the pin configuration and grounding requirement for UCLAMP0504T.TCT?
UCLAMP0504T.TCT uses a 10-pin DFN package with pins 1–5 as GND and pins 6–10 as IN. All five ground pins must be connected to a low-inductance PCB ground plane using multiple vias, and all five input pins must be tied together to the protected line-failure to connect all terminals reduces peak pulse current rating from 24A to ≤12A. This configuration is defined in Semtech's UCLAMP0504T.TCT datasheet and mirrored in the TDS2211P functional layout guidelines.
How does UCLAMP0504T.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)-UCLAMP0504T.TCT uses a triggered FET shunt that maintains near-constant clamping (14.5V ±0.2V from 1A to 24A). This eliminates thermal runaway risk at high temperatures and ensures predictable protection margins for 12V systems, as verified in Semtech's comparative clamping curves for the TDS family, which includes UCLAMP0504T.TCT.
