Product details
Overview
1N6113US 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 20mΩ dynamic resistance. It protects USB Type-C power delivery buses, industrial load switches, and IoT device inputs where stable clamping under temperature and current stress is critical.
For engineers reviewing the 1N6113US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping behavior across temperature, functional comparison vs. conventional TVS diodes, and validated alternatives for 22V bus protection in USB PD and industrial systems.
Technical Context
The 1N6113US employs a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transients to ground. Unlike standard TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24–40A peak pulse current and −40°C to +125°C operating temperature due to the FET's collapsing RDS(on).
It operates with a 22V reverse stand-off voltage (VRWM), 25–27.9V breakdown (VBR), and ultra-low 175pF junction capacitance at 22V/1MHz-enabling use on high-speed power rails without signal integrity degradation. Its six-terminal DFN package assigns pins 1–3 exclusively to GND and pins 4–6 exclusively to IN, requiring all three terminals per side for full 40A surge rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V reverse stand-off voltage (VRWM) - defines maximum continuous DC or RMS operating voltage before conduction begins. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds during surges. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 industrial surge immunity (±1kV, RS = 42Ω). |
| ESD Withstand | ±30kV contact & air discharge (IEC 61000-4-2) - exceeds Level 4 requirements for handheld and portable electronics interfaces. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough to avoid loading 20V power rails while maintaining robust surge handling. |
Pinout & Package
1N6113US is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm 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 |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current - all three must be connected to PCB ground plane via multiple vias to minimize inductance and sustain full 40A rating. |
| Pins 4, 5, 6 | IN | Protected line input - connects directly to VBus, USB PD CC/SBU, or load switch input; all three pins conduct surge current in parallel. |
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 derating uncertainty common with TVS diodes. |
| FET-based shunt topology | Surge-rated MOSFET replaces pn-junction - achieves <0.1Ω effective RDS(on) during conduction, reducing thermal stress and enabling higher IPP in small footprint. |
| Low-capacitance protection | 175pF at 22V - preserves signal integrity on 20V power rails without requiring series impedance or filtering compromises. |
| Industrial-grade surge rating | 1120W peak pulse power (8/20μs) - meets IEC 61000-4-5 for harsh environments including robotics, remote meters, and factory automation. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V nominal VBus in USB-C ports supporting up to 100W PD, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary high-energy EOS suppressor placed between connector and PD controller or buck converter input. Use Value: Maintains 27.5–28V clamping across temperature and current-prevents controller latch-up or gate oxide damage where conventional TVS would exceed 38V at 125°C. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote metering, PLC I/O modules, and robotic power distribution. IC Role / Device Role / Timing Role: Front-end transient shunt that limits voltage seen by the load switch's internal FET gate and drain-source junction. Use Value: Prevents catastrophic failure of the load switch during 40A surges by clamping below its absolute maximum ratings-enabling reliable hot-swap and fault-tolerant operation. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 12–22V auxiliary power inputs in battery-backed edge sensors, smart actuators, and wireless gateways deployed outdoors or in electrically noisy facilities. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on unregulated DC inputs feeding PMICs or LDOs. Use Value: Delivers ±4kV EFT immunity (IEC 61000-4-4) and ±30kV ESD alongside 40A surge handling-reducing BOM count versus multi-stage TVS+MOV approaches. |
Use Scenario: Protecting 22V supercapacitor or LiFePO4 backup supplies in enterprise SSDs, NAS enclosures, and RAID controllers against power rail transients during hot-plug or grid switching. IC Role / Device Role / Timing Role: Low-capacitance, high-IPP clamp on the backup supply rail upstream of power path controllers and data retention circuits. Use Value: 175pF capacitance avoids disrupting charge/discharge timing; stable 28V clamping ensures backup power integrity during sustained 24–40A surges without brownout or reset. |
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 for 1N6113US; shares same marking code T22 and DFN-6 footprint. | Identical use cases: USB PD, load switch, IoT 22V rail protection. | Select when sourcing from Semtech's official channel or requiring traceable lot documentation aligned with Rev 2.5 datasheet. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, 12A IPP (8/20μs), 12pF capacitance - lower surge rating but significantly lower capacitance. | Better suited for CC/SBU lines or low-current control signals where <15pF is mandatory; insufficient for 40A power rail protection. | Choose only for secondary signal-line protection adjacent to 1N6113US - not a functional substitute for main VBus clamping. |
Compared with 1N6113US, TDS2211P offers identical performance and drop-in compatibility, while uClamp2411ZA trades surge capacity for ultra-low capacitance-making it complementary rather than substitutable in primary power rail roles.

FAQ
What is the exact package type and dimensions of the 1N6113US?
The 1N6113US uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed copper pad. Pins 1–3 are GND; pins 4–6 are IN. All six terminals must be soldered-no thermal pad required-as energy is dissipated in the silicon FET. Land pattern follows Semtech's recommended layout with multiple ground vias.
How does the 1N6113US achieve constant clamping voltage across varying surge currents?
The 1N6113US uses a surge-rated FET triggered by an internal precision circuit. When overvoltage occurs, the FET turns on with extremely low RDS(on) (<0.1Ω), causing clamping voltage to stabilize near the trigger circuit's breakdown voltage-not the FET's VGS(th). This results in 27.5–28V clamping from 24A to 40A, unlike TVS diodes whose VC rises linearly with IPP.
Can the 1N6113US replace a standard TVS diode in a 22V USB PD design?
Yes-the 1N6113US is explicitly designed for this role. It provides superior 22V protection versus standard TVS: clamping stays at 27.5–28V (vs. >38V at 125°C for typical TVS), handles 40A surges, and maintains ±30kV ESD immunity. Its 175pF capacitance is compatible with USB PD power rails, unlike sub-1pF signal-line TVS devices.
What is the maximum operating temperature range for the 1N6113US?
The 1N6113US is rated for continuous operation from −40°C to +125°C ambient temperature. Crucially, its clamping voltage remains stable across this full range-27.5–28V at 40A-unlike conventional TVS diodes whose clamping degrades with rising temperature. Junction temperature can reach +150°C during transient events.
Is the 1N6113US RoHS and halogen-free compliant?
Yes-the 1N6113US is fully RoHS/WEEE compliant and halogen-free, with lead-free termination and UL 94V-0 molding compound. It meets global environmental regulations for industrial, computing, and consumer electronics applications without requiring exemptions or special handling.
