Product details
Overview
GS6081-INE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range. Used in USB Type-C PD input protection to safeguard controllers from voltage overshoot.
For engineers reviewing the GS6081-INE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, low 175pF junction capacitance at 22V, and compatibility with industrial and portable device bus protection requirements.
Technical Context
The GS6081-INE3 employs a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under surge-enabling predictable protection at 27.5–28V up to 40A.
It operates over –40°C to +125°C with <20mΩ dynamic resistance and maintains <600nA reverse leakage at 22V. The device protects one line using a symmetrical 6-pin DFN configuration: pins 4–6 serve as protected input, pins 1–3 as ground return-requiring all six pins to be connected for full 40A rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage before leakage or conduction begins. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream ICs see no more than 28V during worst-case surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 ±1kV (RS=42Ω) industrial surge testing. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds Level 4 immunity for handheld and connector-facing interfaces. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough to avoid signal integrity degradation on 22V power rails and slow control lines. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage rise under increasing surge current. |
Pinout & Package
GS6081-INE3 is housed in a RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). 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 - all three must be connected to minimize inductance and sustain full 40A surge capability. |
| Pins 4, 5, 6 | IN | Protected line input - tied together to distribute surge current across parallel paths and reduce trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables near-constant clamping voltage (27.5–28V) across 1–40A surge range-unlike TVS diodes whose VC rises linearly with IPP. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during 40A transients-critical for maintaining tight clamping margin below IC damage thresholds. |
| Wide temperature stability | Clamping voltage varies <0.5V from –40°C to +125°C-eliminates derating concerns in industrial or automotive under-hood environments. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts)-protects against repetitive switching noise in motor drives and PLCs. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping at 40A-well below typical 30V absolute max ratings of PD controllers like STUSB4500 or TUSB7320. |
Use Scenario: Safeguarding input pins of industrial-grade load switches (e.g., ON Semi NIS513x, TI TPS2594x) against lightning-induced surges. IC Role / Device Role / Timing Role: Front-end transient shunt that diverts energy before it reaches the switch's internal FET gate oxide. Use Value: Prevents gate-oxide rupture and latch-up by limiting transient voltage to ≤28V-within safe operating area of 30V-rated load switches. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways exposed to ESD during field servicing or connector mating. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks on compact PCBs. Use Value: 1.6×1.6mm footprint saves >60% board area versus discrete TVS+series resistor solutions while delivering higher surge rating. |
Use Scenario: Protecting 22V supercapacitor or LiFePO4 backup supplies in enterprise SSDs and NAS enclosures. IC Role / Device Role / Timing Role: Standby-mode protector that blocks leakage (<600nA at 22V) yet responds within nanoseconds to fast-rising transients. Use Value: Low 175pF capacitance avoids destabilizing buck-boost regulators feeding NAND flash controllers during power-loss events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Identical electrical specs, same DFN-6 package, identical marking (T22), same tape/reel packaging (3,000/reel). | No functional difference-direct manufacturer-recommended alternate with identical qualification and lot traceability. | Select TDS2211P.C when requiring Semtech's standard commercial-grade variant with full production documentation. |
| uClamp2411ZA.TCT | 24V working voltage, lower 22V clamping (typ. 22V @ 24A), smaller 0.6×0.6mm DFN-2 package, rated for 24A only. | Better suited for CC/SBU lines in USB-C; insufficient for 40A VBus protection due to lower IPP and thermal limits. | Choose uClamp2411ZA.TCT only for low-current, space-constrained auxiliary lines-not as a replacement for GS6081-INE3 on main power rails. |
Compared with TDS2211P.C, GS6081-INE3 shares identical performance and form factor but may differ in date-code tracking or internal lot handling; compared with uClamp2411ZA.TCT, GS6081-INE3 provides 67% higher surge current rating and 22V vs. 24V working voltage-making it the sole suitable option for 22V bus-level protection.

FAQ
What is the maximum continuous operating voltage for GS6081-INE3?
The GS6081-INE3 has a reverse stand-off voltage (VRWM) of 22V, meaning it reliably blocks up to 22V DC without significant leakage. Its reverse breakdown voltage (VBR) starts at 25V (min), confirming safe operation below 22V in normal conditions. This makes GS6081-INE3 ideal for 20V USB PD bus and 22V industrial auxiliary rails.
Does GS6081-INE3 require external components for basic surge protection?
No, GS6081-INE3 operates as a fully self-contained transient suppressor-no series resistors, capacitors, or bias networks are needed. Its integrated FET-trigger architecture activates autonomously during overvoltage events. However, PCB layout best practices (e.g., short traces, multiple GND vias) are essential to preserve its 40A surge rating and 27.5V clamping performance.
How does GS6081-INE3 compare to standard TVS diodes in clamping behavior?
Unlike TVS diodes-whose clamping voltage rises linearly with surge current (VC = VBR + IPP × RDYN)-GS6081-INE3 uses a shunt FET with decreasing RDS(on), resulting in flat clamping: 27.5–28V from 1A to 40A. This eliminates design uncertainty at high currents and elevated temperatures, a key advantage of GS6081-INE3 over traditional solutions.
Can GS6081-INE3 be used on high-speed data lines like USB SS or PCIe?
No-GS6081-INE3 is not intended for high-speed signal lines. Its 175pF junction capacitance would severely degrade signal integrity on SuperSpeed (5–10Gbps) or PCIe lanes. For those, Semtech recommends ultra-low-capacitance devices like RClamp3371ZC (<0.25pF). GS6081-INE3 is strictly for 22V power or low-speed control lines where capacitance is non-critical.
What is the recommended PCB layout for optimal performance of GS6081-INE3?
Place GS6081-INE3 as close as possible to the protected connector. Connect all three IN pins (4–6) via a single low-inductance trace to the protected line, and tie all three GND pins (1–3) directly to a solid ground plane using ≥3 vias. Avoid thermal relief on GND pads. Do not use an isolated thermal pad-energy is dissipated internally, and excessive copper can impair transient response.
