Product details
Overview
1N6162US from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection on single 22V 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 40A, and 20mΩ dynamic resistance. It protects USB Type-C power delivery buses and industrial load switch inputs.
For engineers reviewing the 1N6162US datasheet, pinout, applications, or equivalent options, this device offers stable clamping across temperature and current-critical for USB PD, IoT, and industrial equipment where conventional TVS diodes exhibit rising VC with IPP or temperature.
Technical Context
The 1N6162US 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 the breakdown threshold. Unlike standard TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C, maintains 27.5–28V clamping from 24A to 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω), and delivers 1120W peak pulse power while exhibiting only 175pF junction capacitance at 22V and 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds even at max surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD test mandates. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during conduction, minimizing energy dissipation in the device. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with medium-speed data/power lines; not suitable for >1Gbps differential pairs. |
Pinout & Package
1N6162US is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with six terminals. The compact footprint enables placement directly at connectors for minimal trace inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three pins must be connected to maximize current handling and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS or power rail); parallel connection of all three pins ensures uniform current sharing and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V from 24A to 40A and –40°C to +125°C - eliminates thermal runaway risk seen in conventional TVS. |
| FET-based shunt protection | Surge-rated MOSFET replaces pn-junction, enabling sub-0.1Ω effective RDS(on) and lower thermal stress than silicon avalanche diodes. |
| Low dynamic resistance | 20mΩ measured between 1A and 40A (8/20μs) - reduces voltage overshoot and improves system-level surge margin. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive fast transients in motor drives and PLC environments. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the VBUS line in USB Type-C ports supporting up to 20V/5A PD negotiation, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Transient diverting suppressor placed at connector entry point to clamp overvoltage before reaching PD controller and power switches. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents false shutdown or latch-up in PD controllers rated for ≤30V absolute maximum. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics subject to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Primary front-end EOS protector that limits voltage across the load switch's internal FET gate-source and drain-source terminals. Use Value: Prevents permanent gate oxide damage and drain-source avalanche failure by holding clamping voltage well below 30V ratings of modern e-fuse ICs. |
| IoT Edge Node Power Rail Protection | Storage Device DC Power Input Protection |
Use Scenario: Securing 22V-rated power inputs on battery-backed IoT gateways deployed in unshielded outdoor enclosures. IC Role / Device Role / Timing Role: Single-line TDS device absorbing multi-kA lightning-induced surges coupled via long cables or metal chassis. Use Value: Delivers 1120W peak pulse power handling in 1.6×1.6mm area - replaces bulkier TVS arrays while maintaining board space efficiency. |
Use Scenario: Protecting SATA or NVMe SSD power inputs against hot-plug transients and backplane coupling in enterprise storage racks. IC Role / Device Role / Timing Role: Standoff protector on +12V or +19V supply rails, operating continuously at 22V working voltage with <600nA leakage. Use Value: Ultra-low 130–600nA reverse leakage at 22V ensures no measurable impact on standby power budget in always-on storage subsystems. |
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 manufacturer, identical electrical specs and package - direct functional match; marking differs but die and performance are equivalent. | Identical use cases: USB PD, load switch, industrial 22V rail protection. | Select 1N6162US for standard distribution channels; TDS2211P may be preferred for design-in with Semtech reference schematics. |
| SM712-02HT7 | TVS diode array (bidirectional, 12V standoff); higher clamping (~35V at 25A), no constant-clamp behavior, 2x higher capacitance (350pF). | Limited to lower-energy interfaces (e.g., RS-485, CAN); unsuitable for 22V USB PD due to clamping margin and thermal drift. | Only consider SM712-02HT7 if cost is primary constraint and clamping stability across temperature/current is not required. |
Compared with TDS2211P, 1N6162US offers identical protection performance and form factor; versus SM712-02HT7, it provides superior clamping consistency, lower dynamic resistance, and better thermal robustness - critical for 22V industrial and USB PD designs.

FAQ
What is the working voltage rating of the 1N6162US?
The 1N6162US has a reverse stand-off voltage (VRWM) of 22V, meaning it remains non-conductive under normal operation up to this DC or continuous AC voltage. This makes it suitable for protecting 22V-rated power rails and USB PD VBUS lines without leakage or premature conduction.
Does the 1N6162US meet IEC 61000-4-5 surge immunity standards?
Yes, the 1N6162US is rated for 40A peak pulse current with an 8/20μs waveform and supports ±1kV combination-wave testing (1.2/50μs voltage + 8/20μs current, RS = 42Ω), satisfying IEC 61000-4-5 Level 3 and Level 4 industrial surge requirements for 22V systems.
How does the clamping voltage of the 1N6162US behave across temperature?
The 1N6162US maintains a clamping voltage of 27.5–28V from –40°C to +125°C at 40A, as confirmed in its datasheet's typical characteristics plots. This stability results from its FET-based architecture - unlike standard TVS diodes, its VC does not rise with temperature.
Can the 1N6162US be used on high-speed data lines like USB SuperSpeed?
No, the 1N6162US is not intended for high-speed data lines. With 175pF junction capacitance at 22V, it would severely degrade signal integrity on USB 3.x, PCIe, or DisplayPort lanes. It is designed exclusively for power and medium-speed control lines such as VBUS, CC, SBU, or load switch enable inputs.
What is the package type and pin configuration of the 1N6162US?
The 1N6162US uses a 6-pin DFN package (1.6mm × 1.6mm × 0.55mm) with pins 1–3 assigned to GND and pins 4–6 assigned to IN. All six pins must be soldered - the triple-GND and triple-IN configuration ensures optimal surge current sharing and minimizes parasitic inductance.
