Product details
Overview
LC03-6.TBT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 24–40A, and DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD bus protection.
For engineers reviewing the LC03-6.TBT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and current, low dynamic resistance (<20mΩ), junction capacitance (175pF @ 22V), and validated use in load switch input protection and industrial surge environments per IEC 61000-4-5.
Technical Context
The LC03-6.TBT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with stable 27.5–28V clamping at rated IPP, supported by 22V reverse stand-off voltage, 27.9V typical breakdown, and 130–600nA leakage at VRWM - enabling reliable protection in thermally demanding USB PD and industrial equipment interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds standard USB interface ESD robustness requirements. |
| Junction Capacitance | 175pF @ 22V, 1MHz - compatible with low-speed power/data lines (e.g., VBus, CC, SBU); not suitable for >100MHz signal paths. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
Pinout & Package
LC03-6.TBT is housed in a Pb-free, RoHS-compliant DFN 1.6mm × 1.6mm × 0.55mm 6-lead package with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All pins must be soldered for full 40A rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to PCB ground plane via multiple vias to minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBus, load switch input); all three pins are internally paralleled and must be shorted externally to connector for optimal surge handling. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A and –40°C to +125°C - eliminates derating needed with conventional TVS diodes. |
| FET-based shunt topology | Surge energy diverted through low-RDS(on) channel instead of PN-junction - reduces thermal stress and improves longevity under repeated surges. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive switching noise in industrial motor drives and PLCs. |
| Small-footprint DFN | 1.6×1.6mm area - saves >60% board space vs. SO-8 or SOT-23 TVS alternatives while maintaining 1120W peak power capability. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C PD ports against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents overvoltage damage to 24V-tolerant PD controllers without over-specifying IPP. |
Use Scenario: Shielding e-fuse or load switch inputs (e.g., HS2950P) in remote meters, robotics, and IoT gateways from 1kV/42Ω surges. IC Role / Device Role / Timing Role: Primary front-end EOS protector upstream of integrated load switch, absorbing >95% of surge energy before it reaches sensitive control logic. Use Value: Clamping voltage stays below MOSFET drain-source breakdown (typically <30V), preventing catastrophic failure of internal switch FETs. |
| Storage Device Power Rail Protection | Tablet/Notebook VBus Line Protection |
Use Scenario: Safeguarding 22V-capable SSD or NVMe power rails against system-level ESD coupling and backplane surges. IC Role / Device Role / Timing Role: Standalone rail protector on main 22V supply input, positioned adjacent to edge connector. Use Value: 40A peak current rating supports multi-kV surge standards (IEC 61000-4-5) while 175pF capacitance avoids signal integrity issues on DC power paths. |
Use Scenario: Securing VBus lines in thin-client tablets and 2-in-1 notebooks where board space and thermal constraints limit TVS options. IC Role / Device Role / Timing Role: Compact, low-profile EOS suppressor mounted directly at USB-C receptacle footprint. Use Value: DFN 1.6×1.6mm package enables placement within 3mm of connector - critical for suppressing sub-ns ESD rise times without trace inductance penalties. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Identical electrical specs, same DFN 1.6×1.6mm package, identical pinout and marking (T22XX), but ordered via Semtech's standard reel packaging (3,000 pcs/reel). | No functional difference; used interchangeably in production where tape-and-reel logistics align with OEM assembly lines. | Select TDS2211P.C for volume manufacturing; LC03-6.TBT may reflect legacy distributor-specific marking or packaging variant. |
| uClamp2411ZA | 24V working voltage, lower 30A IPP rating, higher 32V clamping (at 24A), 12pF capacitance - optimized for CC/SBU lines, not power rails. | Designed for low-capacitance data/control lines (not 22V power buses); unsuitable for VBus or load switch input due to insufficient IPP and higher VC. | Use uClamp2411ZA only for auxiliary USB-C signals; LC03-6.TBT remains required for primary 22V power line protection. |
Compared with TDS2211P.C, LC03-6.TBT offers identical protection performance and layout compatibility; versus uClamp2411ZA, LC03-6.TBT provides 33% higher surge current capacity and 4.5V lower clamping - making it the sole viable option for 22V power rail EOS hardening.

FAQ
What is the exact package type and dimensions of LC03-6.TBT?
LC03-6.TBT uses a DFN (Dual Flat No-lead) package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads. Pins 1–3 are GND terminals; pins 4–6 are IN terminals. The package is Pb-free, halogen-free, and RoHS/WEEE compliant with UL 94V-0 flammability rating. No thermal pad is required beneath the die - energy is dissipated within the silicon FET structure.
Does LC03-6.TBT meet IEC 61000-4-5 surge immunity standards?
Yes, LC03-6.TBT is rated for ±1kV (1.2/50μs voltage waveform, RS = 42Ω, CS = 0.5μF) and 40A (8/20μs current waveform) per IEC 61000-4-5, making it suitable for Level 4 industrial surge protection. Its constant-clamp behavior ensures compliance across –40°C to +125°C ambient without derating - unlike standard TVS diodes whose clamping rises with temperature.
Can LC03-6.TBT be used to protect USB SuperSpeed (SS) differential pairs?
No, LC03-6.TBT is not suitable for USB SuperSpeed TX/RX lines. Its 175pF junction capacitance would severely degrade signal integrity above ~100MHz. For SS lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). LC03-6.TBT is intended exclusively for VBus, CC, SBU, or load switch input protection - not high-speed data paths.
How does LC03-6.TBT differ from traditional TVS diodes in clamping behavior?
LC03-6.TBT uses a triggered FET shunt architecture, resulting in near-constant clamping voltage (27.5–28V) across its full 24–40A rating and –40°C to +125°C range. Traditional TVS diodes exhibit linear VC = VBR + IPP × RDYN behavior, causing clamping to rise significantly with current and temperature - often exceeding safe limits for 24V-rated ICs under real-world conditions.
What is the recommended PCB layout for optimal performance of LC03-6.TBT?
Place LC03-6.TBT within 3mm of the protected connector. Connect all three IN pins (4,5,6) via a single low-inductance trace to the protected line, and tie all three GND pins (1,2,3) directly to a solid ground plane using ≥4 vias. Avoid stubs or splits in GND traces. Do not add thermal relief or isolated copper - full GND connectivity is mandatory to achieve rated 40A surge capability.
