Product details
Overview
GS12241-INTE3Z 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 bus protection where low, temperature-invariant clamping prevents damage to 20V-tolerant PD controllers.
For engineers reviewing the GS12241-INTE3Z 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 GS12241-INTE3Z 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-27.5–28V-across 24A to 40A surge currents due to the FET's ultra-low dynamic resistance (20mΩ).
It operates from −40°C to +125°C with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and reverse leakage ≤600nA at VRWM. Its functional architecture enables stable protection in high-temperature industrial environments where traditional TVS devices exhibit rising clamping voltage and reduced IPP capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without triggering |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 20V-tolerant ICs (e.g., USB PD controllers) remain within safe voltage margin |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD systems |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness requirements |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact |
| Dynamic Resistance | 20mΩ (8/20μs) - enables flat clamping curve and minimal voltage rise under increasing surge current |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - enables compact placement near connectors with low-inductance ground path |
Pinout & Package
GS12241-INTE3Z is housed in a Pb-free, RoHS-compliant DFN-6 package (1.6 mm × 1.6 mm × 0.55 mm) with exposed thermal pad not required-energy is dissipated in the FET channel, not the junction. All six terminals must be connected: pins 1–3 are dedicated GND; pins 4–6 are parallel-connected input terminals for surge current sharing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must be vias-connected to internal ground plane for full 40A surge handling |
| Pins 4, 5, 6 | IN | Parallel surge input terminals; connection to protected bus (e.g., VBUS in USB-C); equal current sharing reduces per-pin stress |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V from 24A to 40A surge-enables predictable margin design without derating for temperature or current |
| FET-based shunt topology | Replaces pn-junction TVS with active switching; eliminates thermal runaway risk and improves reliability in sustained overvoltage conditions |
| Ultra-low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs)-minimizes IR drop during surge, preserving clamping accuracy |
| High-temperature stability | Clamping remains 27.5–28V from −40°C to +125°C-eliminates need for thermal derating in industrial enclosures |
| DFN-6 footprint efficiency | 1.6 mm × 1.6 mm area saves >60% board space vs. SO-8 TVS solutions while maintaining 1120W peak power rating |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V nominal VBUS lines in USB-C PD ports against lightning surges and ESD events in portable docking stations. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed directly at connector, clamping transients before they reach PD controller and buck-boost ICs. Use Value: Maintains 27.5–28V clamping across temperature-ensures PD controller (rated 20V max) stays 7–8V below damage threshold even at 125°C ambient. |
Use Scenario: Safeguarding input of high-side load switches (e.g., HS2950P) in remote metering and robotics power distribution modules. IC Role / Device Role / Timing Role: Front-end transient limiter that prevents gate oxide damage and drain-source avalanche failure in the load switch FET. Use Value: Limits voltage seen by load switch to ≤28V during ±1kV IEC 61000-4-5 surges-avoids exceeding 30V absolute maximum rating of industrial-grade e-fuses. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V backup battery rails in cellular IoT gateways exposed to outdoor ESD and induced surges. IC Role / Device Role / Timing Role: Standalone EOS protector on main power input, coordinated with upstream fuse and downstream LDO. Use Value: Delivers ±30kV ESD immunity and 40A surge handling without adding series impedance-preserves voltage regulation accuracy and startup timing. |
Use Scenario: Protecting 22V auxiliary supplies in NVMe SSD enclosures and enterprise NAS units against hot-plug transients and board-level ESD. IC Role / Device Role / Timing Role: Low-capacitance (175pF) shunt device on 22V rail, placed adjacent to connector to minimize trace inductance. Use Value: Prevents latch-up or overvoltage shutdown in PMICs and flash memory controllers during insertion events-no signal distortion on adjacent high-speed data lanes. |
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 | Same die, identical electrical specs, identical DFN-6 package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. GS12241-INTE3Z's unspecified quantity) | No functional difference; suitable for same PCB layouts and thermal designs | Select TDS2211P.C when standard Semtech reel packaging is required for SMT line compatibility |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 33V clamping voltage, smaller 0.65 × 0.65 mm DFN-2 package | Targeted at CC/SBU lines-not rated for 40A surge or 22V power rail duty cycle | Use uClamp2411ZA only for low-current auxiliary signals; not a substitute for GS12241-INTE3Z in VBUS or load switch protection |
Compared with TDS2211P.C, GS12241-INTE3Z offers identical protection performance but may differ in reel logistics; compared with uClamp2411ZA, GS12241-INTE3Z provides 67% higher surge current rating and 5.5V lower clamping-critical for 22V power integrity.

FAQ
What is the exact clamping voltage specification for GS12241-INTE3Z at 40A surge current?
The GS12241-INTE3Z clamps at 27.6–28.0 V under 40A peak pulse current (tp = 8/20μs) with a 1.2/50μs voltage waveform and 2Ω source impedance. This value is guaranteed across −40°C to +125°C and reflects the device's FET-based architecture, which maintains stable voltage regardless of current magnitude within its rated range.
Can GS12241-INTE3Z be used as a direct replacement for standard TVS diodes in existing 22V designs?
GS12241-INTE3Z is not a drop-in replacement for standard TVS diodes due to its 6-pin DFN layout and parallel-terminal architecture. While it shares the same 22V working voltage, its pinout requires dedicated PCB routing: pins 1–3 for GND and pins 4–6 for IN. Layout revision is required to ensure low-inductance grounding and equal current sharing.
Does GS12241-INTE3Z require a thermal pad or heatsink for 40A surge operation?
No. GS12241-INTE3Z dissipates surge energy in the FET channel rather than the PN junction, eliminating thermal pad requirements. The DFN-6 package relies on low-inductance GND vias (pins 1–3) and short, wide traces-not copper area-for effective transient conduction. Thermal pad omission is confirmed in Semtech's layout guidelines.
How does GS12241-INTE3Z perform under high ambient temperature conditions like 105°C?
GS12241-INTE3Z maintains 27.5–28V clamping voltage from −40°C to +125°C, with no increase in VC across temperature. At 105°C, its reverse leakage remains ≤600nA and dynamic resistance stays at 20mΩ-unlike TVS diodes, whose clamping rises significantly above 85°C, making GS12241-INTE3Z ideal for sealed industrial enclosures.
Is GS12241-INTE3Z compliant with RoHS, REACH, and halogen-free standards?
Yes. GS12241-INTE3Z is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and WEEE Directive 2012/19/EU. Its molding compound meets UL 94V-0 flammability rating, and lead finish is 100% matte tin-verified in Semtech's official datasheet Rev 2.5.
