Product details
Overview
1N6107A 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, 20mΩ dynamic resistance, and 175pF junction capacitance at 22V. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and IoT equipment.
For engineers reviewing the 1N6107A datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, constant-clamp behavior across temperature and current, and real-world implementation insights for high-reliability surge protection design.
Technical Context
The 1N6107A 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-from 24A to 40A and across –40°C to +125°C due to decreasing RDS(on) under surge conditions.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V at 1mA, and exhibits only 130–600nA leakage at VRWM. Its 1.6mm × 1.6mm × 0.55mm DFN-6 package integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3) to minimize parasitic inductance and maximize surge current handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without triggering |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD systems |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds automotive and industrial ESD requirements without external shielding |
| Dynamic Resistance | 20mΩ - enables flat clamping response and low voltage overshoot during fast-rising transients |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with 22V bus protection where signal integrity is secondary to robustness |
Pinout & Package
1N6107A 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. Pin 1 location is marked by laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path - all three must be connected to solid ground plane via multiple vias for full 40A surge capability |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals - connect directly to protected line (e.g., USB PD VBus) to distribute surge current and reduce trace inductance |
Key Features
| Feature | Design Value |
|---|---|
| Constant Clamping Voltage | 27.5–28V across full 24–40A range and –40°C to +125°C - eliminates derating uncertainty vs. traditional TVS diodes |
| FET-Based Shunt Architecture | Surge-rated MOSFET triggered by precision circuit - achieves <0.1Ω effective RDS(on), minimizing power dissipation in silicon junction |
| High-Energy Surge Rating | 1120W peak pulse power (8/20μs) - supports repeated lightning-surge events in industrial and metering applications |
| Low-Leakage Protection | ≤600nA reverse leakage at 22V - avoids loading sensitive 22V rails or battery-backed circuits during normal operation |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V USB PD VBus lines from ESD, lightning-induced surges, and connector hot-plug transients in notebooks and docking stations. IC Role / Device Role / Timing Role: Primary shunt protector placed adjacent to Type-C connector, clamping transients before they reach PD controller or buck converter. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to 24V-tolerant PD controllers where standard TVS would exceed 38V at same conditions. |
Use Scenario: Safeguarding input pins of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems exposed to field wiring surges. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Keeps clamping voltage below 30V across temperature - avoids latch-up or permanent damage to load switch ICs rated for ≤30V absolute maximum input. |
| IoT Device Power Rail Protection | Storage Device 22V Auxiliary Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-powered IoT gateways and edge sensors subjected to ESD during handling and installation. IC Role / Device Role / Timing Role: Standalone EOS suppressor on main power input, replacing bulkier multi-stage protection schemes. Use Value: Delivers ±30kV ESD immunity and 40A surge rating in 2.56mm² footprint - enables compact, certified designs without sacrificing reliability. |
Use Scenario: Protecting 22V standby or auxiliary supplies in NVMe SSD enclosures and enterprise storage backplanes against hot-swap and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage shunt device on non-high-speed supply rail, co-located with connector. Use Value: Provides stable 22V working voltage and sub-1μA leakage - preserves system quiescent current budget while meeting IEC 61000-4-5 surge compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, fixed RDYN (~1.2Ω) | Higher clamping voltage increases risk of downstream IC damage at elevated temperatures or currents | Select when cost sensitivity outweighs clamping performance; requires thermal derating above 85°C |
| TDS2211P | Same architecture and specs as 1N6107A; identical pinout, marking, and electrical characteristics per Semtech documentation | No functional difference - TDS2211P is the official Semtech part number; 1N6107A is a legacy or alternate designation | Prefer TDS2211P for new designs to ensure long-term availability and access to latest revision support |
Compared with SMAJ22A, 1N6107A delivers 8–10V lower clamping at full surge current and stable performance across temperature, enabling robust protection for 24V-tolerant ICs. Compared with TDS2211P, 1N6107A is functionally identical but may reflect older packaging or traceability labeling conventions.

FAQ
What is the exact package type and dimensions of the 1N6107A?
The 1N6107A is packaged in a 6-pin DFN (Dual Flat No-lead) case measuring 1.6mm × 1.6mm × 0.55mm with exposed copper terminals. Pins 1–3 are GND; pins 4–6 are IN. The package is Pb-free, RoHS-compliant, and carries UL 94V-0 flammability rating. No thermal pad is required beneath the body.
Does the 1N6107A meet IEC 61000-4-5 surge immunity standards?
Yes, the 1N6107A is rated for 40A peak pulse current using the 8/20μs waveform per IEC 61000-4-5, and supports ±1kV combination-wave testing (1.2/50μs voltage + 8/20μs current, RS = 42Ω). Its 27.5–28V clamping ensures protected circuits remain within safe voltage margins during standardized surge events.
How does the 1N6107A differ from standard TVS diodes like SMAJ22A?
The 1N6107A uses an active FET-based shunt architecture with a precision trigger circuit, delivering near-constant 27.5–28V clamping from 24A to 40A and across –40°C to +125°C. In contrast, SMAJ22A is a passive PN-junction TVS with rising clamping voltage (e.g., ~35.5V at 12.3A) and significant thermal derating above 25°C.
Can the 1N6107A be used to protect USB Type-C CC or SBU lines?
No - the 1N6107A is optimized for 22V power-line protection (e.g., VBus) and is not suitable for low-capacitance, high-speed data lines. For CC/SBU protection, Semtech recommends uClamp2411ZA (24V, <10pF); for SuperSpeed lanes, RClamp3371ZC (<0.25pF) is specified. Using 1N6107A on signal lines would impair signal integrity due to its 175pF capacitance.
What is the maximum operating temperature range for the 1N6107A?
The 1N6107A is specified for continuous operation from –40°C to +125°C ambient temperature, with junction temperature rated up to +150°C. Its clamping voltage remains stable across this full range - unlike conventional TVS devices whose VC rises significantly with temperature - making it ideal for under-hood, industrial, and enclosed thermal environments.
