Product details
Overview
GS12142-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), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance in a DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD bus protection.
For engineers reviewing the GS12142-INTE3Z datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC response, DFN board-space efficiency, and compatibility with industrial surge standards (±1kV, 1.2/50μs + 8/20μs).
Technical Context
The GS12142-INTE3Z 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) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C, maintains stable clamping across temperature (±0.1V variation), and achieves <600nA reverse leakage at 22V. Its 175pF capacitance at 22V/1MHz and 20mΩ dynamic resistance enable robust protection without signal integrity compromise in high-speed power bus applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage of protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD interfaces. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements for connector-facing protection. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough to avoid signal distortion on 20V power rails while enabling effective high-frequency energy shunting. |
| Package | DFN 1.6×1.6×0.55mm, 6-lead - provides 60% smaller footprint than SO-8 TVS alternatives, critical for compact USB-C and IoT designs. |
Pinout & Package
GS12142-INTE3Z is housed in a RoHS-compliant, halogen-free DFN 1.6mm × 1.6mm × 0.55mm 6-lead package with exposed thermal pad not required (energy dissipated in silicon). All pins must be connected: Pins 1–3 are common ground terminals; Pins 4–6 are parallel-connected input terminals for the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path - all three must be soldered to maximize surge current handling and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Parallel-connected input node - connects directly to protected 22V bus (e.g., VCONN, VBUS) and must be placed adjacent to connector for optimal ESD coupling control. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A - eliminates need for derating at high temperatures or currents unlike TVS diodes. |
| FET-based shunt topology | 20mΩ dynamic resistance enables sub-28V clamping at full 40A surge - protects 24V logic interfaces without overvoltage stress. |
| Wide temperature stability | Clamping holds within 27.5–28V from –40°C to +125°C - ensures consistent protection in industrial and automotive ambient conditions. |
| Low-leakage design | ≤600nA at 22V - prevents power loss or false triggering in always-on 22V systems such as USB PD sink circuits. |
| High-energy EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - suppresses burst noise on power rails in motor drives and PLC modules. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the 20–22V VBUS line in USB-C receptacles supporting up to 100W PD. IC Role / Device Role / Timing Role: Primary EOS shunt device placed between connector and PD controller or load switch, responding within nanoseconds to voltage transients. Use Value: Maintains 27.5–28V clamping across full 40A surge and –40°C to +125°C, preventing latch-up or gate oxide damage in 24V-rated PD controllers. |
Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by the load switch's internal FET during lightning-induced surges. Use Value: Keeps clamping voltage below the 30V absolute maximum rating of typical 24V-input load switches, avoiding catastrophic failure during ±1kV IEC 61000-4-5 events. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
|

Use Scenario: Shielding 22V supercapacitor or LiFePO4 backup supplies in NVMe SSDs and enterprise storage controllers. IC Role / Device Role / Timing Role: Bidirectional transient clamp on backup power path, conducting surge energy to ground without forward conduction loss. Use Value: 0.5V forward voltage and <600nA leakage preserve backup runtime; 175pF capacitance avoids interference with fast charge/discharge timing. |
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 marking (T22), same tape-and-reel packaging (3,000/reel). | No functional difference - TDS2211P.C is the standard orderable variant; GS12142-INTE3Z is Semtech's alternate part number for the same die and assembly. | Select TDS2211P.C for standard procurement; GS12142-INTE3Z may appear in legacy BOMs or distributor cross-listings. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but lower 20A IPP (8/20μs), higher 33V clamping at 20A, SOD-323 package (larger, 2-pin). | Targeted at CC/SBU lines in USB-C, not main VBUS; lacks parallel-pin architecture and thermal robustness for 40A surges. | Use only for low-current auxiliary lines; not suitable as direct replacement for GS12142-INTE3Z in 22V power rail protection. |
Compared with TDS2211P.C (identical device) and uClamp2411ZA (lower-power alternative), GS12142-INTE3Z offers guaranteed 40A surge handling and flat 27.5–28V clamping in the smallest possible footprint - making it the sole choice for space-constrained, high-reliability 22V bus protection where thermal and layout margins are tight.

FAQ
What is the exact package type and dimensions of GS12142-INTE3Z?
GS12142-INTE3Z uses a DFN (Dual Flat No-lead) package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The package is Pb-free, halogen-free, and RoHS/WEEE compliant with UL 94V-0 flammability rating.
Does GS12142-INTE3Z meet IEC 61000-4-5 surge immunity requirements?
Yes, GS12142-INTE3Z is rated for 40A peak pulse current (8/20μs waveform) and withstands ±1kV combination wave surges (1.2/50μs voltage + 8/20μs current, RS = 42Ω), satisfying IEC 61000-4-5 Level 4 for industrial environments. Its 27.5–28V clamping ensures protected devices remain within safe operating limits.
How does GS12142-INTE3Z differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), GS12142-INTE3Z 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 derating and improving predictability in harsh environments.
Can GS12142-INTE3Z be used on bidirectional data lines like USB DP/DM?
No - GS12142-INTE3Z is optimized for unidirectional 22V power or I/O line protection (e.g., VBUS, load switch input). For high-speed data lines such as USB DP/DM, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25pF); GS12142-INTE3Z's 175pF capacitance would degrade signal integrity.
What is the maximum operating temperature range for GS12142-INTE3Z?
GS12142-INTE3Z is specified for continuous operation from –40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range (27.5–28V at 40A), and junction temperature is rated to +150°C - enabling use in sealed industrial enclosures and automotive under-hood auxiliary systems.
