Product details
Overview
LC01-6.TDT from Semtech is a transient diverting suppressor designed for high-energy EOS/ESD protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range. It protects USB Type-C VBus, load switch inputs, and industrial power rails.
For engineers reviewing the LC01-6.TDT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (20 mΩ), junction capacitance (175 pF), and DFN 1.6×1.6mm 6-lead package compatibility with high-density USB PD and IoT layouts.
Technical Context
The LC01-6.TDT 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 nearly constant-27.5–28V at 24A and 40A-due to decreasing RDS(on) under surge.
It operates over −40°C to +125°C, maintains <600 nA reverse leakage at 22V, and delivers 1120W peak pulse power. Its functional architecture separates trigger threshold (25–27.9V breakdown) from conduction path, enabling robust protection without thermal runaway in industrial and USB PD applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds during surge |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD test levels for connector-facing protection |
| Dynamic Resistance | 20 mΩ - enables low-voltage drop during high-current transients, minimizing energy dissipation in silicon |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - compatible with 20V USB PD bus lines without signal integrity impact |
| Package | DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead - supports ultra-compact placement near Type-C connectors or load switches |
Pinout & Package
LC01-6.TDT is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All six terminals are surface-mount; pin 1 is marked by laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three must be connected to maximize current handling and minimize inductance |
| 4, 5, 6 | IN | Protected line input (e.g., VBus); parallel connection of all three pins ensures uniform current sharing and optimal 40A capability |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5 V from 24A to 40A surge - eliminates design margin inflation needed with TVS diodes |
| FET-based shunt topology | Surge energy diverted through low-RDS(on) channel instead of PN-junction - avoids thermal derating above 25°C |
| High-temp stable performance | Clamping remains 27.5–28 V from −40°C to +125°C - enables reliable protection in uncooled industrial enclosures |
| Low-leakage standby | ≤600 nA at 22 V and 125°C - prevents battery drain or bias shift in always-on IoT power rails |
| Compact DFN footprint | 1.6 mm × 1.6 mm area - saves >60% board space vs. SO-8 or SOT-23 TVS solutions rated for same 40A surge |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20V–22V VBus lines in USB-C ports against lightning-induced surges and connector ESD events. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between connector and USB PD controller or load switch. Use Value: Maintains 27.5–28V clamping at full 40A surge and 125°C ambient - prevents PD controller latch-up where standard TVS would exceed 38V. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient clamp preventing gate oxide damage and overvoltage failure of internal FETs. Use Value: Limits voltage across load switch input to ≤28V during ±1kV IEC 61000-4-5 surges - avoids destructive breakdown of integrated control circuitry. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
|
Use Scenario: Securing 22V auxiliary power inputs in battery-backed smart sensors exposed to field ESD and induced transients. IC Role / Device Role / Timing Role: Standalone transient diverter on main DC input, upstream of LDOs and PMICs. Use Value: Delivers 40A surge handling in 1.6 mm² footprint - enables compact, sealed enclosures without external heat sinking or layout compromises. |
Use Scenario: Protecting 22V backup power inputs in NVMe SSDs and enterprise storage controllers during hot-plug and system-level surges. IC Role / Device Role / Timing Role: High-reliability clamping device on VBackup rail, co-located with connector interface. Use Value: Stable 27.5–28V clamping ensures backup controller ICs remain within absolute maximum ratings even after repeated 40A transients. |
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 and DFN 1.6×1.6mm package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. LC01-6.TDT's unspecified reel count) | No functional difference; suitable for identical USB PD and industrial use cases | Select TDS2211P.C when standard Semtech reel quantity and traceability are required |
| uClamp2411ZA | 24V working voltage, lower 24A surge rating, higher 30V clamping, and smaller 0.6×0.6mm 2-pin package | Better suited for CC/SBU lines in USB-C; insufficient for 40A VBus protection | Use uClamp2411ZA only for low-current auxiliary lines-not as direct replacement for LC01-6.TDT on power rails |
Compared with TDS2211P.C, LC01-6.TDT offers identical protection performance but may differ in reel logistics; versus uClamp2411ZA, LC01-6.TDT provides 67% higher surge current capacity and 2.5V lower clamping-critical for 22V power rail integrity.

FAQ
What is the maximum continuous operating voltage for LC01-6.TDT?
The LC01-6.TDT has a reverse stand-off voltage (VRWM) of 22 V, meaning it reliably blocks up to 22 V DC in normal operation while maintaining leakage below 600 nA. This makes LC01-6.TDT suitable for 20V USB PD VBus and other 22V-rated industrial power rails without false triggering or thermal stress.
Does LC01-6.TDT require a thermal pad on the PCB?
No, LC01-6.TDT does not require an external thermal pad. Its FET-based architecture dissipates surge energy in the silicon channel rather than at a PN junction, eliminating the need for copper thermal slugs. The DFN package relies on low-inductance GND connections (pins 1–3) and short traces to manage transient energy-per Semtech's layout guidelines.
How does LC01-6.TDT achieve stable clamping voltage across temperature?
LC01-6.TDT achieves stable clamping by using a precision trigger circuit to activate a low-RDS(on) shunt FET. As temperature rises, the FET's on-resistance decreases, counteracting typical semiconductor voltage drift. This results in consistent 27.5–28V clamping from −40°C to +125°C-unlike TVS diodes whose clamping increases linearly with temperature.
Can LC01-6.TDT be used on high-speed data lines like USB SuperSpeed?
No, LC01-6.TDT is not intended for high-speed data lines. With 175 pF junction capacitance, it is optimized for 22V power rails (e.g., VBus, load switch inputs), not signal integrity-critical paths. For USB SS, DP/DM, or CC lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25 pF) alongside LC01-6.TDT in a layered protection scheme.
What is the pin configuration and recommended PCB layout for LC01-6.TDT?
LC01-6.TDT uses a 6-pin DFN: pins 1–3 are GND, pins 4–6 are IN. All three GND pins must connect to a solid ground plane via multiple vias; all three IN pins must tie together with a single short trace to the protected line. Placement must be adjacent to the connector-within 5 mm-to minimize inductive coupling during fast ESD events, as specified in the official LC01-6.TDT layout guide.
