Product details
Overview
GS1670AIBE3 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 full current and temperature range (−40°C to +125°C). It is used in USB Type-C PD bus protection where low, temperature-invariant clamping prevents damage to voltage-sensitive controllers.
For engineers reviewing the GS1670AIBE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, dynamic resistance <20 mΩ, junction capacitance of 175 pF at 22V, and DFN 1.6×1.6mm package compatibility with high-density USB PD and industrial load switch layouts.
Technical Context
The GS1670AIBE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, its clamping voltage remains nearly constant because the FET's RDS(on) collapses under surge, minimizing voltage rise with increasing IPP.
It operates with reverse stand-off voltage (VRWM) of 22V, breakdown voltage (VBR) of 25–27.9V, and dynamic resistance of 20 mΩ measured between 1A and 40A (8/20μs). Its functional architecture enables stable clamping at 27.5–28V up to 40A while maintaining <600 nA leakage at VRWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below absolute maximum ratings during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards for connector-facing protection. |
| Junction Capacitance | 175 pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Dynamic Resistance | 20 mΩ - enables flat clamping curve; reduces voltage overshoot compared to TVS diodes with fixed RDYN >1 Ω. |
Pinout & Package
GS1670AIBE3 is housed in a RoHS-compliant DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead package with exposed thermal pad (no solder mask defined). All three GND pins must be connected for full 40A surge capability; all three IN pins must be paralleled to minimize trace inductance and ensure uniform current sharing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; requires low-inductance connection to PCB ground plane via multiple vias. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBUS); must be routed as single low-inductance trace from connector. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A (8/20μs), eliminating design margin inflation needed with TVS diodes. |
| Temperature-stable protection | Clamping remains 27.5–28V across −40°C to +125°C - avoids derating or thermal shutdown in industrial environments. |
| Low dynamic resistance | 20 mΩ enables efficient energy shunting with minimal IR drop, reducing localized heating during repeated surges. |
| High-energy EOS handling | 1120W peak pulse power rating supports sustained surge events in USB PD and industrial power rails. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C receptacles against lightning-induced surges and hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt device placed directly at connector, diverting transients before they reach PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents controller latch-up or gate oxide damage where standard TVS would clamp >38V. |
Use Scenario: Safeguarding input of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics against 1kV/42Ω surges. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage seen by internal FET drain-source junction during EOS events. Use Value: Keeps clamping voltage below 30V - avoids avalanche failure or gate-source overvoltage in integrated load switches rated for ≤30V max VDS. |
| IoT Device Power Rail Protection | Notebook/Tablet Main Power Input Protection |
Use Scenario: Securing 22V input rails in battery-powered IoT gateways exposed to ESD during field servicing or docking. IC Role / Device Role / Timing Role: Single-component solution replacing multi-stage TVS+MOV designs, reducing BOM count and board area. Use Value: 175 pF capacitance and DFN 1.6×1.6mm footprint enable placement near connectors without compromising RF or signal integrity. |
Use Scenario: Protecting main system power input (e.g., barrel jack or USB-C port) in portable computing devices against accidental 1.2/50μs surges. IC Role / Device Role / Timing Role: Standalone transient suppressor for unidirectional 22V supply lines, eliminating need for series impedance or filtering. Use Value: ±30kV ESD rating and 4kV EFT immunity meet IEC 61000-4-4/-2 compliance for CE-marked consumer electronics. |
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 1.6×1.6mm package, identical pinout and marking (T22XX), same Semtech production lot traceability. | No functional difference; TDS2211P.C is the direct orderable variant with 3,000-unit tape-and-reel packaging. | Select TDS2211P.C when requiring Semtech's standard distribution packaging and full datasheet alignment with GS1670AIBE3. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, 0.25pF junction capacitance, SOD-323 package - optimized for CC/SBU lines, not power rails. | Designed for low-capacitance data-line protection; unsuitable for 22V power rail due to lower surge rating and different thermal profile. | Choose uClamp2411ZA only for auxiliary signal lines (CC, SBU); GS1670AIBE3 remains required for VBUS-level protection. |
Compared with TDS2211P.C (identical performance, alternate packaging) and uClamp2411ZA (lower IPP, signal-line optimized), GS1670AIBE3 provides validated 40A surge handling and thermal stability for 22V power rail applications where clamping consistency is critical.

FAQ
What is the exact clamping voltage specification for GS1670AIBE3 at 40A surge current?
The GS1670AIBE3 clamps at 27.6–28V under 40A peak pulse current (tp = 1.2/50μs voltage + 8/20μs current combination waveform, RS = 2Ω), as guaranteed by design per Semtech's TDS2211P datasheet Rev 2.5. This value is stable across −40°C to +125°C ambient temperature.
Is GS1670AIBE3 pin-compatible with TDS2211P.C?
Yes - GS1670AIBE3 and TDS2211P.C share identical pin configuration (Pins 1–3 = GND, Pins 4–6 = IN), mechanical dimensions (DFN 1.6×1.6×0.55mm), marking code (T22XX), and electrical specifications. They are functionally and physically interchangeable in layout.
Does GS1670AIBE3 require a thermal pad or special PCB copper pour?
No - GS1670AIBE3 dissipates surge energy in the FET channel, not the junction, so no thermal pad is needed. However, all three GND pins must connect to a solid ground plane using ≥3 vias each, and all three IN pins must be routed as one low-inductance trace to maximize 40A surge performance.
Can GS1670AIBE3 be used to protect bidirectional data lines like USB DP/DM?
No - GS1670AIBE3 is unidirectional (GND-to-IN), rated for 22V working voltage on power or single-ended I/O lines. For DP/DM protection, Semtech recommends RClamp3371ZC (0.25pF, 3.3V), which is specifically designed for high-speed bidirectional signal integrity.
What is the maximum operating temperature range for GS1670AIBE3?
GS1670AIBE3 is specified for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range, and junction temperature is rated to +150°C, supporting use in sealed industrial enclosures and automotive under-hood proximity.
