Product details
Overview
1N6113AUS 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 ultra-low 20mΩ dynamic resistance. It protects USB Type-C power delivery buses and industrial load switch inputs.
For engineers reviewing the 1N6113AUS datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, clamping stability across temperature and current, and direct alternatives for 22V bus protection in USB PD, IoT, and industrial equipment.
Technical Context
The 1N6113AUS 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-across 24–40A and −40°C to +125°C due to decreasing RDS(on) under surge.
It operates with three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3) in a 1.6mm × 1.6mm DFN package, requiring all six pins to be connected for full 40A rating. Its 175pF junction capacitance at 22V and 1MHz suits moderate-speed power/data line protection without signal integrity compromise.
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 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - stays below 30V damage threshold of most 24V-rated 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 industrial ESD requirements without external staging. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping vs. current, unlike TVS diodes whose VC rises linearly with IPP. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB PD CC/SBU and load switch enable lines; not suitable for SuperSpeed data lanes. |
| Operating Temp | −40°C to +125°C - supports extended industrial and automotive under-hood environments. |
Pinout & Package
1N6113AUS is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder connection required). All six terminals must be connected: three GND pins for low-inductance return path and three IN pins for parallel surge current sharing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground | Low-inductance return path; all three must be connected to solid ground plane via multiple vias for full 40A capability. |
| Pins 4, 5, 6 | Input / Protected Line | Parallel-connected surge input terminals; all three must tie directly to protected bus (e.g., VBus or load switch input) with minimal trace length. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS with active shunt architecture, delivering stable clamping independent of surge magnitude or temperature. |
| Constant clamping over current range | 27.5–28V across full 24–40A rating - eliminates need for oversized TVS to meet worst-case VC at high IPP. |
| Ultra-low dynamic resistance | 20mΩ enables minimal IR drop during surge - critical for protecting low-voltage-tolerance ICs downstream of load switches. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz & 5kHz bursts) - ensures robustness against repetitive switching noise in motor drives and PLCs. |
| Small-footprint DFN packaging | 1.6mm × 1.6mm saves >60% board area vs. SO-8 or SOT-23 TVS solutions rated for comparable energy. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V USB PD bus lines from lightning-induced surges and connector hot-plug transients in portable and docking stations. IC Role / Device Role / Timing Role: Primary EOS shunt device placed at Type-C connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.5–28V clamping across temperature and current-unlike TVS diodes whose VC rises to >38V at 125°C-ensuring consistent controller safety margin. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) against EOS in remote meters, robotics, and factory automation. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by the load switch's internal FET gate and drain, preventing latch-up or oxide rupture. Use Value: 40A surge rating and 20mΩ RDYN ensure fast, low-loss diversion-keeping clamp voltage well below 30V even during 8/20μs surges at full rating. |
| IoT Edge Node Power Bus Protection | Industrial Equipment DC Power Input Protection |
Use Scenario: Securing 12–24V DC power inputs of battery-powered IoT sensors and gateways exposed to ESD during field servicing or environmental coupling. IC Role / Device Role / Timing Role: Single-device solution for both ESD (±30kV) and surge (±1kV IEC 61000-4-5) on main supply rail, eliminating cascaded protection stages. Use Value: 175pF capacitance avoids power-rail instability while enabling full ±30kV ESD compliance-critical for compact, unshielded enclosures. |
Use Scenario: Hardening 24V DC input of programmable logic controllers (PLCs), HMIs, and motor drives against induced surges from nearby AC switching or lightning. IC Role / Device Role / Timing Role: High-energy transient suppressor placed upstream of input filter and DC-DC converter, absorbing >1kV surges before system-level filtering. Use Value: 1120W peak pulse power rating and −40°C to +125°C operation guarantee reliability in harsh cabinet environments with wide ambient swings. |
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; 1N6113AUS is Semtech's alternate ordering code for TDS2211P. | No functional difference; used interchangeably in BOMs and schematics. | Select 1N6113AUS when sourcing through distributors using legacy part numbering; verify marking "T22" on unit. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping at 20A, 12pF capacitance. | Better suited for low-capacitance CC/SBU lines in USB Type-C; insufficient for 40A bus-level protection. | Choose uClamp2411ZA only for auxiliary signal lines-not as a replacement for 1N6113AUS on main power rails. |
Compared with TDS2211P (identical function) and uClamp2411ZA (lower energy rating, lower capacitance), the 1N6113AUS delivers unmatched 40A surge handling and flat 27.5–28V clamping for 22V bus protection-making it the sole choice where industrial surge immunity and thermal stability are mandatory.

FAQ
What is the exact package type and footprint for 1N6113AUS?
The 1N6113AUS uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no electrical connection required). Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. Land pattern follows Semtech's recommended layout with multiple vias to ground plane for optimal surge performance.
Does 1N6113AUS meet IEC 61000-4-5 surge immunity standards?
Yes, the 1N6113AUS is rated for 40A peak pulse current (8/20μs waveform) and withstands ±1kV combination wave (1.2/50μs voltage + 8/20μs current, RS = 42Ω) per IEC 61000-4-5, making it suitable for Level 4 industrial surge protection on 22V power rails and load switch inputs.
How does 1N6113AUS differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes-whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN)-the 1N6113AUS uses an active FET shunt that maintains 27.5–28V clamping across its full 24–40A rating and −40°C to +125°C operating range, ensuring predictable protection margins.
Can 1N6113AUS be used on USB SuperSpeed differential pairs (TX/RX)?
No, the 1N6113AUS has 175pF junction capacitance at 22V-too high for USB 3.x/3.2 SuperSpeed lanes, which require <0.25pF devices like RClamp3371ZC. It is intended for VBus, CC, SBU, and load switch power/enable lines-not high-speed data paths.
Is 1N6113AUS pin-compatible with other Semtech TDS devices?
The 1N6113AUS shares the same DFN-6 pinout (3×GND / 3×IN) and mechanical footprint as TDS2211P, but not with other TDS variants like TDS1211P (12V) or TDS3311P (33V), which use identical packaging but different internal trigger thresholds and clamping voltages.
