Product details
Overview
UCLAMP2411ZATFT from Semtech is a single-line transient voltage suppression (TVS) diode designed for board-level ESD protection of 24V DC power rails and high-speed data lines. It delivers ±20 kV air/±17 kV contact ESD immunity per IEC 61000-4-2, 150 W peak pulse power (8/20 µs), 45 V clamping voltage at 2 A, 9–15 pF junction capacitance, and ultra-low 0.05–0.1 µA reverse leakage at 24 V.
For engineers reviewing the UCLAMP2411ZATFT datasheet, pinout, applications, or equivalent options, key selection considerations include its SLP0603P2X3F 0.6 × 0.3 mm package, bidirectional conduction, low dynamic resistance (1 Ω), and suitability for space-constrained portable electronics requiring robust, low-capacitance surge protection.
Technical Context
The UCLAMP2411ZATFT employs silicon-avalanche TVS technology optimized for fast response to sub-nanosecond ESD transients. Its symmetrical bidirectional structure enables protection of either polarity on a single line without ground reference dependency.
It operates with a 24 V working voltage and clamps to ≤45 V under 2 A 8/20 µs surges, while maintaining <15 pF capacitance-critical for preserving signal integrity on USB, HDMI, or display data lines in mobile devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 24 V - defines maximum continuous DC operating voltage before leakage rises significantly |
| ESD Rating (IEC 61000-4-2) | ±20 kV air / ±17 kV contact - meets industrial-grade ESD immunity requirements for handheld and portable equipment |
| Clamping Voltage | 45 V at 2 A (8/20 µs) - limits downstream voltage stress during surge events to safe levels for 24V-rated ICs |
| Junction Capacitance | 9–15 pF at 0 V - low enough to avoid signal degradation on high-speed interfaces like MIPI D-PHY or LVDS |
| Peak Pulse Power | 150 W (8/20 µs) - supports robust protection against repetitive EFT and cable discharge events |
| Dynamic Resistance | 1 Ω - ensures minimal voltage overshoot during fast TLP pulses (0.2/100 ns) |
Pinout & Package
UCLAMP2411ZATFT is housed in the ultra-compact SLP0603P2X3F package (0.6 × 0.3 × 0.25 mm), lead-free NiAu-plated, RoHS/WEEE compliant. The device is bidirectional and has no polarity marking; both terminals are electrically identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Connects to protected line; interchangeable with Pin 2 due to symmetrical TVS structure |
| Pin 2 | Anode/Cathode (bidirectional) | Connects to system ground or return path; functionally identical to Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 0.6 × 0.3 mm SLP0603P2X3F package enables placement directly at connector or IC I/O pad |
| Bidirectional ESD protection | Symmetrical clamping allows use on AC-coupled or floating lines without polarity concerns |
| Low clamping voltage | 45 V max at 2 A ensures compatibility with 24 V logic and power ICs' absolute maximum ratings |
| Low leakage current | ≤0.1 µA at 24 V minimizes standby power loss in battery-powered systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC package (4.5 × 2.7 mm), 300 W PPK, 38.9 V VBR, 64 V VC @ 25 A | Higher clamping, larger footprint - suited for industrial power rail protection, not portable data lines | Select SMAJ24A only when board space permits and higher surge current (>10 A) is required |
| TPD2E001DRYR | 2-channel, 5.5 V working voltage, 10 pF, SOT-553 package - rated for 3.3/5 V systems only | Not rated for 24 V operation; unsuitable for DC power rail protection | Choose TPD2E001DRYR for dual low-voltage data line protection where UCLAMP2411ZATFT's 24 V rating is unnecessary |
Compared with SMAJ24A and TPD2E001DRYR, the UCLAMP2411ZATFT uniquely balances 24 V operation, ultra-miniature size, and sub-15 pF capacitance-making it the only viable option for ESD-hardened 24 V data/power interfaces in space-constrained portable designs.

FAQ
What is the maximum continuous operating voltage for UCLAMP2411ZATFT?
The UCLAMP2411ZATFT has a reverse stand-off voltage (VRWM) of 24 V, meaning it can safely operate continuously at up to 24 V DC without significant leakage current. This makes UCLAMP2411ZATFT ideal for protecting 24 V power rails and compatible with industrial and automotive auxiliary power domains where nominal voltages align with this rating.
Does UCLAMP2411ZATFT require a ground connection to function?
Yes - UCLAMP2411ZATFT must be connected between the protected line and system ground (or return path) to shunt transient energy. As a bidirectional TVS, it conducts equally in both directions, but relies on a low-inductance ground path to achieve specified clamping performance. Proper PCB layout with short, wide traces to ground is essential for UCLAMP2411ZATFT to meet its 45 V clamping specification.
Can UCLAMP2411ZATFT be used on high-speed data lines like USB 2.0 or MIPI?
Yes - UCLAMP2411ZATFT's 9–15 pF junction capacitance and low dynamic resistance (1 Ω) make it suitable for USB 2.0, MIPI D-PHY, and other high-speed interfaces operating below 480 Mbps. Its fast response time preserves signal edge integrity, and its 24 V rating allows use on powered data lines (e.g., USB-C VBUS-adjacent CC lines). Always verify eye diagram compliance in final UCLAMP2411ZATFT layout.
What is the thermal derating behavior of UCLAMP2411ZATFT above 25°C?
UCLAMP2411ZATFT's peak pulse power rating decreases linearly above 25°C ambient, with full 150 W capability only at TJ ≤ 25°C. At 85°C junction temperature, its PPK drops to approximately 90 W. Derating curves are provided in the official Semtech datasheet Rev 3.1. System-level thermal design must ensure UCLAMP2411ZATFT's junction stays within −40°C to +85°C under worst-case surge repetition.
Is UCLAMP2411ZATFT compatible with lead-free reflow processes?
Yes - UCLAMP2411ZATFT is qualified for lead-free soldering per JEDEC J-STD-020, with a maximum peak reflow temperature of 260°C. Its NiAu lead finish and SLP0603P2X3F package support standard Type 4 solder paste and 0.100 mm stencil thickness. Semtech recommends non-solder-mask-defined pads and OSP or NiAu PCB finishes to ensure reliable UCLAMP2411ZATFT solder joint formation.
