Product details
Overview
GV7700-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 a stable 27.5–28V clamping voltage across temperature and current range. It is used in USB Type-C PD input protection to safeguard controllers from voltage overshoot during lightning surges or ESD events.
For engineers reviewing the GV7700-INE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, low dynamic resistance (20mΩ), and compatibility with industrial-grade operating temperatures (−40°C to +125°C).
Technical Context
The GV7700-INE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage and rapidly shunts transient energy to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under increasing surge current.
It operates with a 22V reverse stand-off voltage and 27.9V typical breakdown voltage, supporting unsymmetrical line protection per IEC 61000-4-5 (±1kV, 1.2/50μs). Its 175pF junction capacitance at 22V/1MHz enables use on moderate-speed power rails without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs see <28V during worst-case surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial ESD immunity standards |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimal VC rise across 1–40A range |
| Junction Capacitance | 175pF at 22V/1MHz - suitable for DC power bus and low-to-moderate speed control lines |
| Operating Temp | −40°C to +125°C - supports extended industrial and automotive under-hood environments |
Pinout & Package
GV7700-INE3 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound.
| 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 handling and minimize inductance |
| 4, 5, 6 | IN | Protected line input terminal; connects to VBus, load switch input, or power rail requiring EOS suppression |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers near-constant clamping voltage (27.5–28V) from 1A to 40A, unlike TVS diodes whose VC rises linearly with IPP |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during surge, preserving clamping accuracy across temperature and current |
| High-temperature clamping stability | Clamping voltage remains unchanged from −40°C to +125°C - critical for industrial and automotive thermal environments |
| Compact DFN-6 footprint | 1.6mm × 1.6mm saves >50% board area vs. traditional SOT-23 or SOIC TVS solutions while maintaining 1120W peak power rating |
| Unsymmetrical line surge rating | Rated for ±1kV (1.2/50μs, RS=42Ω) - directly applicable to USB PD and industrial power rail protection |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the VBus input of USB Type-C PD controllers against lightning-induced surges and contact ESD. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed between connector and PD controller input, clamping transients before they reach sensitive logic. Use Value: Maintains clamping at ≤28V across full 40A surge and −40°C to +125°C, preventing controller latch-up or gate oxide damage where standard TVS would exceed 35V. |
Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics against 1kV line surges. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage stress on the load switch's internal MOSFET during EOS events. Use Value: Keeps clamping voltage below the FET's absolute maximum VDS, avoiding avalanche failure and enabling reliable operation without derating at high ambient temperatures. |
| IoT Device Power Rail Protection | Notebook/Tablet DC Power Input Protection |
|
Use Scenario: Securing 22V-capable power inputs in battery-powered IoT gateways exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution for DC bus protection, replacing multi-component TVS+capacitor networks. Use Value: 175pF capacitance avoids signal distortion on 22V supply rails while delivering ±30kV ESD robustness - eliminating need for additional filtering. |
Use Scenario: Protecting the main DC input stage of ultrabooks and tablets accepting up to 20V USB PD charging. IC Role / Device Role / Timing Role: High-reliability surge clamp positioned at the DC jack or Type-C port entry point. Use Value: Stable 27.5V clamping ensures compliance with system-level safety margins even at 85°C ambient, reducing thermal derating overhead in compact thermal envelopes. |
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 code "T22" - direct Semtech factory variant with tape-and-reel packaging | No functional difference; differs only in packaging format (reel vs. tray) and traceability labeling | Select TDS2211P.C for volume production with automated pick-and-place; GV7700-INE3 is functionally identical and qualified for same applications |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 30V clamping, smaller 0.65mm × 0.65mm DFN-2 package | Targeted at CC/SBU lines in USB Type-C, not power bus protection - insufficient for 40A surge or 22V continuous operation | Not a functional replacement for GV7700-INE3; use only for auxiliary signal-line protection where lower surge rating and voltage margin are acceptable |
Compared with TDS2211P.C, GV7700-INE3 offers identical protection performance and package; compared with uClamp2411ZA, GV7700-INE3 provides 2× peak current rating, 22V vs. 24V standoff, and optimized thermal design for power-rail placement - making it the sole suitable choice for 22V bus-level EOS suppression.

FAQ
What is the maximum continuous operating voltage for GV7700-INE3?
The GV7700-INE3 has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously withstand up to 22V DC or RMS on its IN pins relative to GND without leakage exceeding 600nA. This makes it suitable for 20V USB PD and 22V industrial power rails where sustained voltage margin is critical.
Does GV7700-INE3 require external components like series resistors or capacitors for basic operation?
No, GV7700-INE3 is a fully self-contained transient suppressor requiring no external components for core EOS protection. Its integrated FET-trigger architecture eliminates the need for RC networks or biasing. Layout best practice mandates direct, low-inductance connection of all GND (pins 1–3) and IN (pins 4–6) terminals to respective planes.
How does GV7700-INE3's clamping voltage compare to standard TVS diodes under surge conditions?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GV7700-INE3 maintains 27.5–28V clamping from 1A to 40A due to its FET-based architecture and 20mΩ dynamic resistance. At 40A and 125°C, it clamps ~10V lower than a typical 22V TVS diode.
Can GV7700-INE3 be used on high-speed data lines such as USB SuperSpeed or PCIe?
No, GV7700-INE3 is not intended for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on >100MHz differential pairs. It is designed exclusively for DC power rails and low-speed control lines; for USB SS or DP/DM, Semtech recommends RClamp3371ZC (<0.25pF).
What is the recommended PCB layout for optimal surge performance of GV7700-INE3?
Place GV7700-INE3 within 5mm of the protected connector. Connect all three GND pins (1–3) to a solid ground plane using ≥3 vias each, and tie all three IN pins (4–6) together with a short, wide trace to the protected line. Avoid stubs or routing gaps - parasitic inductance directly degrades clamping response during fast ESD events.
