Product details
Overview
GS12241-INTE3 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, and 20mΩ dynamic resistance. It protects USB Type-C power delivery buses, load switch inputs, and industrial interfaces where stable clamping under temperature and current stress is critical.
For engineers reviewing the GS12241-INTE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping behavior across temperature, and validated alternatives for 22V bus protection in USB PD, IoT, and industrial equipment.
Technical Context
The GS12241-INTE3 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 - across 24A to 40A peak pulse current and from –40°C to +125°C due to decreasing RDS(on) under surge conditions.
It operates with a 22V reverse stand-off voltage (VRWM) and 25–27.9V reverse breakdown (VBR), exhibits only 130–600nA leakage at VRWM, and maintains 175pF junction capacitance at 22V/1MHz - enabling use on high-speed power rails without signal integrity compromise.
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 24V-rated 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 input stages. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements without derating. |
| Dynamic Resistance | 20mΩ - enables low-voltage-drop shunting, minimizing energy dissipation in the device and reducing thermal stress. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with DC power rails and low-speed control lines; avoids resonance or filtering issues. |
Pinout & Package
GS12241-INTE3 is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All six terminals must be connected for full 40A surge rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be tied to solid ground plane via multiple vias to minimize inductance. |
| Pins 4, 5, 6 | IN | Protected line input - connects directly to VBus, load switch input, or USB PD power rail; all three pins conduct surge current in parallel. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A and remains stable across –40°C to +125°C - eliminates thermal derating uncertainty in industrial deployments. |
| FET-based shunt topology | Replaces PN-junction TVS with low-RDS(on) MOSFET, reducing clamping voltage by ~10V vs. comparable 22V TVS at 40A and 125°C. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events in remote meters and robotics without parameter shift. |
| Low-leakage protection | Max 600nA reverse leakage at 22V enables use on always-on battery-backed rails without measurable drain. |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input |
|---|---|
Use Scenario: Protecting 20V–22V VBus lines in USB-C receptacles supporting up to 100W 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 across temperature and current - prevents false overvoltage shutdown and ensures PD controller survival during 40A surges. |
Use Scenario: Shielding enable and input pins of high-side load switches (e.g., HS2950P) in programmable logic controllers and smart sensors. IC Role / Device Role / Timing Role: Front-end transient guard for load switch VIN/EN pins exposed to field wiring transients. Use Value: Clamps below 28V to avoid gate oxide stress or internal FET avalanche in load switches rated for ≤30V absolute max. |
| IoT Edge Node Power Rail | Storage Device 24V Backup Supply |
Use Scenario: Securing 22V auxiliary power inputs in battery-powered gateways and cellular modems deployed outdoors. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on unregulated DC input. Use Value: Delivers ±4kV EFT immunity (IEC 61000-4-4) and ±30kV ESD without external RC filters - simplifies BOM and layout. |
Use Scenario: Safeguarding 22V backup battery inputs in NVMe SSD enclosures and RAID controllers subjected to hot-plug transients. IC Role / Device Role / Timing Role: Standoff protector for battery management IC inputs during insertion/removal events. Use Value: 175pF capacitance avoids interference with battery voltage monitoring accuracy while blocking >27V transients. |
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), and shared Semtech qualification - direct manufacturing variant of GS12241-INTE3. | No functional difference; used interchangeably in USB PD reference designs and industrial schematics. | Select TDS2211P.C when sourcing from authorized Semtech distributors with standard reel packaging (3,000 pcs/reel). |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but lower 20A IPP rating and higher 33V clamping at 20A - lacks constant-clamp FET architecture. | Suitable for CC/SBU lines in USB-C, not for 22V power rails requiring 40A surge handling. | Choose uClamp2411ZA only for low-current signal lines; not a functional replacement for GS12241-INTE3 on power paths. |
Compared with TDS2211P.C (identical performance, alternate ordering code) and uClamp2411ZA (lower surge rating, higher clamping), GS12241-INTE3 delivers unique constant-voltage clamping at 40A - making it the only option among the three qualified for 22V industrial power rail protection with guaranteed <28V turn-on behavior across temperature.

FAQ
What is the exact package type and dimensions of GS12241-INTE3?
GS12241-INTE3 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed pad (no thermal pad required). Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. Land pattern follows Semtech's recommended layout with multiple vias to ground for optimal surge current handling.
Does GS12241-INTE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS12241-INTE3 is rated for 40A peak pulse current (8/20μs waveform) and complies with IEC 61000-4-5 Level 4 for unsymmetrical lines (±1kV, 1.2/50μs voltage, 8/20μs current, RS = 42Ω). Its 27.5–28V clamping ensures protected circuits remain within safe operating limits during standardized surge tests.
How does GS12241-INTE3 differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS12241-INTE3 uses a triggered FET shunt that maintains near-constant clamping - 27.5–28V from 24A to 40A and across –40°C to +125°C - eliminating thermal and current derating uncertainties.
Can GS12241-INTE3 be used on USB-C superspeed data lines?
No, GS12241-INTE3 is not suitable for USB-C SS TX/RX differential pairs due to its 175pF junction capacitance, which would distort high-speed signals. It is intended exclusively for 22V power rails (VBus, load switch inputs); low-capacitance devices like RClamp3371ZC (<0.25pF) are specified for superspeed line protection.
What is the maximum operating temperature range for GS12241-INTE3?
GS12241-INTE3 is fully specified from –40°C to +125°C ambient operating temperature. Its clamping voltage remains stable across this range, and junction temperature is rated to +150°C - enabling deployment in sealed industrial enclosures and automotive under-hood environments with validated thermal margin.
