Product details
Overview
GS1671AIBE3 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. It is used in USB Type-C PD bus protection where low, temperature-invariant clamping prevents damage to 20V-tolerant controllers.
For engineers reviewing the GS1671AIBE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over 40A surge current, DFN-6 thermal and layout performance, 175pF junction capacitance at 22V, and compatibility with industrial-grade load switch input protection schemes.
Technical Context
The GS1671AIBE3 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 due to decreasing RDS(on) under surge - not fixed dynamic resistance.
It operates across –40°C to +125°C with <20mΩ dynamic resistance (measured 1–40A, 8/20μs), 22V reverse stand-off, and 27.9V typical breakdown. Its functional architecture enables stable 27.5–28V clamping at both 24A and 40A IPP, independent of ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - Maximum continuous operating voltage before conduction begins; matches USB PD 20V bus with safety margin. |
| Clamping Voltage (IPP = 40A) | 27.5–28 V - Stable voltage limit during worst-case 40A surge; stays within safe margin for 20V-rated PD controllers. |
| Peak Pulse Current (8/20μs) | 40 A - Withstands high-energy surges per IEC 61000-4-5; supports industrial lightning and load-dump immunity. |
| ESD Withstand (IEC 61000-4-2) | ±30 kV contact & air - Robust front-end protection against human-body and proximity discharge events. |
| Junction Capacitance | 175 pF @ 22V, 1MHz - Low enough for DC power rail protection without signal integrity impact on adjacent traces. |
| Dynamic Resistance | 20 mΩ - Enables flat clamping curve; ensures minimal voltage rise even as surge current scales from 1A to 40A. |
| Operating Temperature Range | –40°C to +125°C - Fully specified performance across automotive and industrial ambient conditions. |
Pinout & Package
GS1671AIBE3 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads and UL 94V-0 flammability rating. All pins must be connected for full surge rating: three GND pins provide low-inductance return path; three IN pins share surge current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - must all be connected to minimize parasitic inductance and maximize 40A surge current capability. |
| 4, 5, 6 | IN | Protected line input - connects directly to VBus or power/data line; all three pins conduct surge current in parallel. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage across IPP range | 27.5–28 V from 24A to 40A - eliminates need for oversized TVS to meet clamping target at high temperature. |
| Temperature-stable clamping | No increase in VC from –40°C to +125°C - enables reliable protection in uncontrolled thermal environments. |
| Surge-rated FET protection architecture | RDS(on) collapses under surge - avoids junction heating failure mode common in silicon avalanche TVS devices. |
| Low dynamic resistance | 20 mΩ - reduces IR drop during surge, maintaining tight clamping window without external series impedance. |
| DFN-6 footprint | 1.6 mm × 1.6 mm - saves >50% board area vs. SOIC-8 or SOT-23 alternatives while supporting same 40A rating. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20V USB PD VBus lines against ESD, lightning-induced surges, and hot-plug transients in portable and docking stations. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed at connector entry point; clamps transients before reaching PD controller IC. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - avoids overvoltage damage to 20V-rated controllers where standard TVS would exceed 38V. |
Use Scenario: Safeguarding input terminals of industrial load switches (e.g., HS2950P) exposed to field wiring surges in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage seen by internal FET gate oxide and drain-source junction. Use Value: Prevents latch-up or permanent damage to load switch by holding clamping below 30V - well under typical 35V absolute max ratings. |
| IoT Device Power Rail Protection | Notebook/Tablet DC Power Input Protection |
|
Use Scenario: Securing 12–24V DC input rails in battery-powered IoT edge nodes deployed in electrically noisy environments. IC Role / Device Role / Timing Role: Single-component, low-capacitance surge diverter for compact, thermally constrained PCB layouts. Use Value: 175pF capacitance avoids filtering issues on DC rails; 40A rating covers EN 61000-4-5 Level 4 requirements without derating. |
Use Scenario: Protecting 20V adapter inputs in ultrabooks and tablets against accidental AC mains coupling and ESD during port insertion. IC Role / Device Role / Timing Role: High-reliability, space-efficient alternative to multi-diode TVS arrays in thin-profile power input stages. Use Value: DFN-6 footprint fits narrow board edges; ±30kV ESD rating exceeds IEC 61000-4-2 Level 4 for consumer product certification. |
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; manufactured by Semtech with same revision history. | No functional difference - direct second-source part with identical qualification and traceability. | Select TDS2211P.C when requiring Semtech's official branded reel packaging and full compliance documentation. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, 0.25pF capacitance - optimized for CC/SBU lines, not power rails. | Designed for low-capacitance data-line protection; unsuitable for 40A VBus protection due to lower surge rating. | Choose uClamp2411ZA only for auxiliary signal lines (CC, SBU); GS1671AIBE3 remains required for main power rail protection. |
Compared with TDS2211P.C, GS1671AIBE3 offers identical performance and form factor but may differ in tape-and-reel logistics or date-code traceability; compared with uClamp2411ZA, GS1671AIBE3 provides 67% higher surge current capacity and is rated for power-line duty - not signal-line use.

FAQ
What is the maximum clamping voltage of GS1671AIBE3 at 40A surge current?
The GS1671AIBE3 clamps at 27.5–28 V under 40A peak pulse current (tp = 8/20μs), with RS = 2Ω, per IEC 61000-4-5 combination waveform testing. This value is guaranteed across –40°C to +125°C and reflects the device's FET-based architecture, which maintains near-constant clamping unlike conventional TVS diodes.
Is GS1671AIBE3 pin-compatible with TDS2211P.C?
Yes, GS1671AIBE3 is pin-compatible with TDS2211P.C: both use identical 6-pin DFN (1.6 mm × 1.6 mm) packages with matching pin 1 location, GND on pins 1–3, and IN on pins 4–6. Layout, solder mask, and land pattern are fully interchangeable per Semtech's published DFN outline drawing.
Can GS1671AIBE3 be used to protect USB SuperSpeed differential pairs?
No, GS1671AIBE3 is not suitable for USB SuperSpeed (TX/RX) lines. Its 175pF junction capacitance would severely degrade signal integrity. For those lines, Semtech recommends ultra-low-capacitance devices like RClamp3371ZC (<0.25pF); GS1671AIBE3 is intended exclusively for DC power or single-ended I/O rail protection.
What is the reverse leakage current specification for GS1671AIBE3 at 22V?
At VRWM = 22V and TA = 25°C, GS1671AIBE3 exhibits reverse leakage current between 130 nA and 600 nA. This low leakage ensures minimal standby power loss in always-on industrial or battery-backed applications, and remains stable across temperature per published leakage vs. temperature curves.
Does GS1671AIBE3 require a thermal pad or heatsink for 40A surge handling?
No, GS1671AIBE3 does not require a thermal pad or external heatsink. Its surge energy is dissipated via the FET channel during transient conduction, not junction heating. Semtech explicitly states no thermal pad is needed - proper PCB layout (multiple vias to ground plane, short traces) suffices for full 40A rating.
