Product details
Overview
GS12142-INTE3 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, and stable performance from −40°C to +125°C - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the GS12142-INTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and current, low dynamic resistance (20 mΩ), DFN-6 package footprint, and compatibility with 22V bus architectures requiring robust surge immunity per IEC 61000-4-5.
Technical Context
The GS12142-INTE3 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 the full 1–40A peak pulse range due to decreasing RDS(on) under surge conditions.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and exhibits only 130–600 nA leakage at VRWM. Its 175 pF junction capacitance at 22V/1MHz and 20 mΩ dynamic resistance enable low-voltage overshoot control without signal integrity compromise on DC power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - stays below 30V damage threshold of common load switches and PD controllers. |
| Peak Pulse Current | 40 A (8/20μs) - satisfies IEC 61000-4-5 Level 4 (±1 kV, RS = 42 Ω) for industrial equipment. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity requirements. |
| Dynamic Resistance | 20 mΩ - ensures minimal voltage rise during fast transients, critical for protecting sensitive downstream FETs. |
| Junction Capacitance | 175 pF at 22 V / 1 MHz - low enough for DC power line use; avoids resonance or filtering issues on 22V rails. |
Pinout & Package
GS12142-INTE3 is housed in a RoHS-compliant DFN-6 package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed thermal pad not required - optimized for space-constrained USB-C and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to maximize current handling and minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS or load switch input); parallel connection ensures uniform current sharing and optimal clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5 V across 1–40A surge range - eliminates need for over-spec'ed IPP to meet voltage limits. |
| Temperature-stable protection | Clamping remains 27.5–28 V from −40°C to +125°C - enables reliable operation in uncooled industrial enclosures. |
| Low dynamic resistance | 20 mΩ measured between 1A and 40A - reduces transient-induced voltage overshoot on protected bus. |
| DFN-6 footprint | 1.6 mm × 1.6 mm area - saves >60% board space vs. SO-8 or SOT-23 alternatives while maintaining 40A capability. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting the VBUS line of a USB-C port supporting up to 20V/5A PD negotiation against lightning surges and connector hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at the connector, diverting surge energy to GND before it reaches the PD controller or buck converter. Use Value: Maintains clamping at ≤28 V across temperature and current - prevents latch-up or gate oxide damage in 22V-tolerant PD ICs like STUSB4500 or TUSB7320. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, PLC I/O modules, and robotic power distribution units. IC Role / Device Role / Timing Role: Front-end transient limiter that clamps incoming surges before they stress the internal MOSFET's drain-source breakdown rating. Use Value: Keeps peak voltage at switch input below 30 V during 40A transients - avoids avalanche failure and extends lifetime of integrated e-fuse devices. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing the main 22V input rail of battery-backed wireless gateways or cellular edge routers exposed to outdoor surge environments. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on DC input - replaces multi-component TVS+MOV stacks. Use Value: Delivers ±4 kV EFT immunity (IEC 61000-4-4) and 40A surge handling in 2.56 mm² - enables compact, certified Class B industrial designs. |
Use Scenario: Protecting the 22V auxiliary supply rail feeding NVMe SSD power management ICs or backup SRAM in enterprise storage arrays. IC Role / Device Role / Timing Role: Low-capacitance (175 pF), low-leakage (≤600 nA) protector preserving rail stability during long-term standby operation. Use Value: Prevents cumulative degradation from repeated sub-kV transients - maintains data retention integrity during extended power-loss events. |
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" - direct Semtech manufacturing variant with tape-and-reel packaging. | No functional difference; used interchangeably in production where reel quantity (3,000 pcs) aligns with assembly planning. | Select TDS2211P.C when sourcing from authorized Semtech distributors with standard reel logistics. |
| uClamp2411ZA | 24 V working voltage, lower 20 A IPP rating, higher 33 V clamping at 20 A - less robust for 40A surge scenarios. | Targeted at CC/SBU lines in USB-C, not VBUS; unsuitable for 22V power rail protection due to higher clamping and lower surge rating. | Not recommended as functional replacement; use only for auxiliary signal-line protection where lower IPP suffices. |
Compared with TDS2211P.C, GS12142-INTE3 shares identical specifications and form factor but may differ in traceability or qualification grade; versus uClamp2411ZA, GS12142-INTE3 provides 2× peak current capacity and 5 V lower clamping - making it the sole suitable option for 22V DC power rail EOS hardening.

FAQ
What is the maximum operating temperature range for GS12142-INTE3?
The GS12142-INTE3 is rated for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range - confirmed by characterization data showing ≤0.3 V variation in VC from −40°C to +125°C at 40A - making it suitable for sealed industrial enclosures without active cooling.
Does GS12142-INTE3 require a thermal pad on the PCB?
No, GS12142-INTE3 does not require a thermal pad. The device dissipates surge energy through conduction rather than junction heating, and its DFN-6 package is designed for direct copper pour connection to ground planes. Layout guidelines specify using multiple vias under pins 1–3 to minimize inductance - not thermal relief.
Can GS12142-INTE3 be used on high-speed data lines like USB SuperSpeed?
No, GS12142-INTE3 is not intended for high-speed data lines. With 175 pF junction capacitance, it would severely degrade signal integrity on differential pairs. It is specified exclusively for DC power or low-frequency I/O lines such as USB-C VBUS, load switch inputs, or 22V backup rails - not SSTX+/SSTX− or DP/DM.
How does GS12142-INTE3 compare to standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS12142-INTE3 uses an active FET-based architecture that holds clamping voltage nearly constant (27.5–28 V) from 1A to 40A. This eliminates design margin uncertainty caused by temperature- and current-dependent voltage overshoot in conventional solutions.
Is GS12142-INTE3 compliant with RoHS and halogen-free standards?
Yes, GS12142-INTE3 is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. 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 and supported by material declarations available upon request.
