Product details
Overview
1N6107AUS from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB PD, Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the 1N6107AUS datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and real-world implementation details for EOS-critical bus protection.
Technical Context
The 1N6107AUS 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 across 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with <600nA reverse leakage at 22V, 175pF junction capacitance at 22V/1MHz, and maintains stable 27.5–28V clamping up to 125°C - a key advantage over standard TVS devices whose clamping rises with temperature and current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD VBus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below 30V damage threshold of common load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB IF and IEC 61000-6-2 requirements for end-equipment certification. |
| Dynamic Resistance | 20mΩ - enables low-voltage overshoot during fast transients and minimizes power dissipation in FET channel. |
| Junction Capacitance | 175pF at 22V/1MHz - suitable for DC power rails and low-speed control lines; not for >100MHz signal paths. |
Pinout & Package
1N6107AUS is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals must be connected per datasheet layout guidelines to achieve rated 40A surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return for surge current; requires low-inductance multi-via connection to internal ground plane. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBus); all three pins must be shorted externally to maximize current sharing and minimize parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers flat clamping voltage vs. current and temperature - eliminates design margin inflation needed with TVS diodes. |
| Ultra-low dynamic resistance | 20mΩ ensures minimal IR drop during 40A surges, preserving downstream voltage integrity during fault events. |
| High-temperature stability | Clamping remains ≤28V from –40°C to +125°C - enables reliable protection in uncooled industrial enclosures. |
| Low leakage & capacitance | ≤600nA @ 22V and 175pF @ 1MHz - avoids standby power loss and signal distortion on power rails. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector entry point to clamp EOS before reaching PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping across full temperature range, preventing false OVP trips and enabling use of lower-cost 30V-rated downstream ICs. |
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: Primary front-end surge diverter that limits voltage stress on internal MOSFET gate oxide and drain-source junction. Use Value: Prevents latch-up or permanent failure of load switches during 1kV/42Ω IEC 61000-4-5 surges by holding clamping below 30V. |
| IoT Device Power Rail Protection | Notebook/Tablet DC Input Protection |
Use Scenario: Securing 22V auxiliary power inputs in battery-powered IoT gateways exposed to field ESD and induced transients. IC Role / Device Role / Timing Role: Solid-state EOS protector replacing bulkier TVS arrays while delivering superior clamping consistency. Use Value: 1.6mm × 1.6mm footprint saves >60% board area versus discrete TVS + RC snubber solutions. |
Use Scenario: Hardening 20V DC-in ports on ultrabooks and tablets against accidental adapter misconnection and AC-line coupled surges. IC Role / Device Role / Timing Role: First-line transient suppressor upstream of buck converters and battery charge management ICs. Use Value: ±30kV ESD rating and stable clamping ensure compliance with IEC 61000-6-2 and UL 62368-1 system-level safety tests. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same die, identical electrical specs and DFN-6 package; 1N6107AUS is Semtech's alternate ordering code for TDS2211P. | No functional difference; used interchangeably in BOMs and schematics per Semtech documentation. | Select 1N6107AUS when sourcing through distribution channels requiring legacy part numbering; no layout or validation changes required. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 35V clamping, smaller 0.65mm × 0.65mm DFN-2 package. | Better suited for CC/SBU lines in USB-C; insufficient for 40A VBus protection. | Use uClamp2411ZA only for low-current signal lines; 1N6107AUS remains mandatory for main power rail protection. |
Compared with TDS2211P, 1N6107AUS is an identical device with identical performance and footprint - it is a manufacturer-assigned alternate part number, not a variant. Compared with uClamp2411ZA, 1N6107AUS provides 2× higher surge current handling and 7–8V lower clamping, making it the sole viable option for 22V power rail EOS protection.

FAQ
What is the exact relationship between 1N6107AUS and TDS2211P?
The 1N6107AUS is Semtech's alternate orderable part number for the TDS2211P device. Both share identical silicon die, electrical specifications, DFN-6 package dimensions, pinout, and thermal characteristics. No schematic, layout, or qualification changes are needed when substituting 1N6107AUS for TDS2211P in production.
Does 1N6107AUS require a thermal pad or heatsink on the PCB?
No. The 1N6107AUS dissipates surge energy primarily through conduction via its GND pins (1–3) and IN pins (4–6), not junction heating. Semtech explicitly states no thermal pad is needed - instead, low-inductance multi-via connections to a solid ground plane are required to handle 40A peak current without voltage overshoot.
Can 1N6107AUS be used on high-speed data lines like USB SS or PCIe?
No. With 175pF junction capacitance at 22V, the 1N6107AUS introduces excessive signal loading on high-speed differential pairs. It is intended exclusively for DC power rails and low-speed control lines. For USB SuperSpeed or DisplayPort, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF).
What is the maximum operating temperature for continuous DC bias on 1N6107AUS?
The 1N6107AUS supports continuous operation from –40°C to +125°C ambient. Its reverse leakage remains ≤600nA at 22V up to +125°C, and clamping voltage stays within 27.5–28V across this full range - enabling deployment in sealed industrial enclosures without active cooling.
How does 1N6107AUS improve reliability compared to standard TVS diodes in 22V applications?
Unlike TVS diodes whose clamping voltage rises linearly with current and temperature (VC = VBR + IPP × RDYN), the 1N6107AUS maintains ≤28V clamping from 24A to 40A and from –40°C to +125°C. This eliminates over-clamping risks that can damage 30V-rated PD controllers or load switches during worst-case surge + thermal conditions.
