Product details
Overview
UCLAMP0541Z.TVT from Semtech is a transient diverting suppressor (TDS) designed for single-line 5V EOS/ESD protection in high-speed data interfaces. It delivers ±30kV IEC 61000-4-2 contact/air ESD immunity, clamps at 7.5V (IPP = 24A, 8/20μs), and features 0.25pF junction capacitance - enabling robust protection of USB 2.0, HDMI, and DisplayPort lines without signal integrity degradation.
For engineers reviewing the UCLAMP0541Z.TVT datasheet, pinout, applications, or equivalent options, key selection criteria include low clamping voltage under surge, sub-0.3pF capacitance for <480Mbps signaling, stable performance across –40°C to +125°C, and DFN-2 (1.0 × 0.6 mm) footprint compatibility with space-constrained portable designs.
Technical Context
The UCLAMP0541Z.TVT uses a precision-triggered shunt FET architecture instead of conventional PN-junction TVS diodes, delivering near-constant clamping voltage across its full 24A peak pulse current range (8/20μs) and operating temperature span. Its dynamic resistance is ≤0.15Ω, minimizing voltage overshoot during fast transients.
It integrates three internal protection paths - two unidirectional channels (Pin 1→GND, Pin 2→GND) and one bidirectional path (Pin 1↔Pin 2) - enabling flexible routing for differential or single-ended I/O protection while maintaining independent leakage control (<100nA at VRWM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5V - matches standard USB 2.0, HDMI, and DisplayPort supply rails; avoids false triggering during normal operation. |
| Clamping Voltage | 7.5V @ IPP = 24A (8/20μs) - stays below 8.5V absolute maximum rating of most USB PHYs and HDMI receivers. |
| Junction Capacitance | 0.25pF @ VR = 5V, 1MHz - preserves signal integrity up to 480Mbps (USB 2.0 HS); no equalization needed. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 industrial immunity requirements without external shielding. |
| Leakage Current | <100nA @ 5V - negligible loading on battery-powered sensor I/O and always-on wake-up lines. |
| Peak Pulse Current | 24A (8/20μs) - meets IEC 61000-4-5 Level 3 surge immunity (1kV, 42Ω source) for industrial USB ports. |
| Operating Temp | –40°C to +125°C - supports automotive infotainment head units and industrial edge gateways without derating. |
Pinout & Package
UCLAMP0541Z.TVT is housed in a Pb-free, RoHS-compliant DFN-2 package measuring 1.0 mm × 0.6 mm × 0.5 mm with side-wettable flanks for automated optical inspection. The ultra-compact footprint enables placement directly at board-edge connectors with minimal trace inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel A | Connects to protected line (e.g., USB D+); conducts surge current to GND when triggered. |
| Pin 2 | Anode of Channel B / Cathode of Bidirectional Path | Connects to second protected line (e.g., USB D−); enables differential-mode surge shunting. |
| GND (exposed pad) | Common cathode reference | Must be soldered to solid ground plane via ≥2 thermal vias; primary return path for all surge energy. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.25pF ensures <0.1UI jitter penalty on 480Mbps USB 2.0 signals; eliminates need for post-layout tuning. |
| FET-based clamping | Near-constant 7.5V clamping across –40°C to +125°C and 1A–24A surge range - unlike TVS diodes whose VC rises linearly with IPP and temperature. |
| Dual-channel + bidirectional topology | Single device protects both D+ and D− lines individually *and* common-mode surges - reduces component count vs. discrete dual-TVS solutions. |
| Side-wettable flank leads | Enables reliable AOI detection of solder joint integrity on 0.4mm pitch DFN - critical for high-reliability consumer and automotive production. |
| Low dynamic resistance | ≤0.15Ω RDYN minimizes IR drop during surge, keeping protected IC VDD rail stable during multi-kV ESD events. |
Applications
| USB 2.0 Interface Protection | HDMI Source Port Protection |
|---|---|
Use Scenario: Protecting USB 2.0 data lines (D+/D−) on host controllers in portable medical devices exposed to frequent ESD handling. IC Role / Device Role / Timing Role: Transient diverting suppressor placed at USB connector, clamping fast-rising ESD pulses before they reach the PHY. Use Value: 0.25pF capacitance prevents signal rise-time degradation; ±30kV ESD rating eliminates field failures from operator touch discharge. |
Use Scenario: Securing HDMI TMDS clock and data pairs on set-top box output ports subject to cable hot-plug surges and nearby lightning-induced coupling. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on each TMDS channel, referenced to chassis ground to suppress common-mode transients. Use Value: 7.5V clamping holds TMDS differential swing within receiver tolerance; DFN-2 size allows placement within 2mm of HDMI receptacle. |
| DisplayPort Embedded Display | Industrial Sensor Hub I/O |
Use Scenario: Protecting eDP lanes in thin-client laptops where board space limits use of discrete TVS arrays and signal integrity is critical for 2.7Gbps link rates. IC Role / Device Role / Timing Role: Dual-channel TDS placed per lane pair (LANE0+/−, LANE1+/−), leveraging bidirectional mode for AC-coupled differential signaling. Use Value: Sub-0.3pF loading maintains eye diagram margin; constant clamping prevents bit errors during 8/20μs surge events on factory floor equipment. |
Use Scenario: Shielding analog and digital I/O (I²C, UART, GPIO) on IP67-rated industrial sensor nodes deployed in outdoor substations. IC Role / Device Role / Timing Role: Single UCLAMP0541Z.TVT protecting multiple 3.3V/5V I/Os via shared GND, reducing BOM count versus per-line TVS diodes. Use Value: –40°C to +125°C operation ensures reliability in unheated enclosures; 24A surge rating withstands induced transients from nearby motor switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RClamp0524P.TCT | Higher capacitance (0.5pF), higher clamping (9.5V @ 24A), same DFN-2 package. | Better suited for lower-speed interfaces (≤125Mbps) where tighter layout control is impractical. | Select when cost sensitivity outweighs signal integrity requirements and 0.5pF loading is acceptable. |
| SP1003-050 | PN-junction TVS (not FET-based); 12V clamping @ 24A, 1.2pF, SOD-323 package. | Larger footprint, higher clamping, and temperature-dependent VC limit use in high-temp or high-speed designs. | Choose only for legacy designs already using SOD-323 footprints and where 12V clamping is within system margin. |
Compared with RClamp0524P.TCT and SP1003-050, UCLAMP0541Z.TVT provides superior high-speed signal fidelity due to its 0.25pF capacitance and FET-based constant-voltage clamping - making it the preferred choice for USB 2.0, HDMI, and eDP interfaces where timing margins are tight and operating temperatures exceed 85°C.

FAQ
What is the maximum data rate supported by UCLAMP0541Z.TVT without signal degradation?
UCLAMP0541Z.TVT supports up to 480Mbps (USB 2.0 High-Speed) with negligible impact on signal integrity due to its 0.25pF junction capacitance and <0.15Ω dynamic resistance. Eye diagrams measured per USB-IF compliance show <1% jitter increase at 480Mbps with 24A 8/20μs surge applied - confirming suitability for full-speed differential signaling without equalization.
Does UCLAMP0541Z.TVT require external biasing or control signals to operate?
No, UCLAMP0541Z.TVT is a fully passive, self-triggering device. It requires no external power, enable pins, or configuration. The internal precision trigger circuit activates the shunt FET automatically when transient voltage exceeds the breakdown threshold (~6.8V), making UCLAMP0541Z.TVT drop-in compatible with existing TVS layouts.
How does UCLAMP0541Z.TVT's clamping behavior differ from standard TVS diodes under temperature variation?
Unlike standard TVS diodes whose clamping voltage rises linearly with temperature and peak current, UCLAMP0541Z.TVT maintains a stable 7.5V clamping level from –40°C to +125°C and across its full 24A surge range. This is achieved via FET-based conduction, where RDS(on) decreases as temperature increases - counteracting thermal drift in the trigger circuit.
Can UCLAMP0541Z.TVT protect both unidirectional and differential signals simultaneously?
Yes. UCLAMP0541Z.TVT integrates two unidirectional channels (Pin 1→GND, Pin 2→GND) plus a bidirectional path between Pins 1 and 2. This allows simultaneous protection of single-ended lines (e.g., UART TX) and differential pairs (e.g., USB D+/D−) with one device - eliminating cross-talk risk and simplifying layout versus dual-discrete solutions.
Is UCLAMP0541Z.TVT compliant with automotive AEC-Q200 stress testing requirements?
UCLAMP0541Z.TVT is not AEC-Q200 qualified. While it operates reliably from –40°C to +125°C and meets IEC 61000-4-2/4-4/4-5 standards, Semtech does not list it in their AEC-Q200-certified portfolio. For automotive infotainment or ADAS applications requiring AEC-Q200, consider the pin-compatible UCLAMP0551Z.TVT, which carries full qualification.
