Product details
Overview
GS12142-INE3 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 ranges. It is deployed in USB Type-C PD bus protection where low, temperature-invariant clamping prevents damage to voltage-sensitive controllers.
For engineers reviewing the GS12142-INE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over temperature, dynamic resistance <20mΩ, DFN 1.6×1.6mm package constraints, and compatibility with industrial surge standards (±1kV, 1.2/50μs + 8/20μs).
Technical Context
The GS12142-INE3 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 due to decreasing RDS(on) under surge conditions - not fixed dynamic resistance.
It operates across –40°C to +125°C with reverse stand-off voltage of 22V, breakdown at 25–27.9V, and junction capacitance of 175pF at 22V/1MHz. Its functional architecture enables robust protection for unsymmetrical lines without thermal derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs see ≤28V during worst-case surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD stress levels |
| Dynamic Resistance | 20mΩ - enables low-voltage drop and minimal power dissipation during conduction |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with moderate-speed data/power lines (e.g., USB PD VBUS) |
| Package | DFN 1.6×1.6×0.55mm, 6-lead - supports ultra-compact PCB layout near connectors |
Pinout & Package
GS12142-INE3 is housed in a Pb-free, RoHS-compliant DFN 1.6mm × 1.6mm × 0.55mm package with exposed thermal pad (no internal thermal pad required). All six terminals are surface-mount; pins 1–3 form a common ground connection, and pins 4–6 serve as parallel input terminals for the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path - all three must be connected to maximize surge current handling and minimize parasitic inductance |
| 4, 5, 6 | IN | Parallel-connected input terminals for protected bus - all three must be tied together externally to ensure uniform current sharing and full 40A rating |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across 24–40A and –40°C to +125°C - eliminates thermal derating and simplifies margin analysis |
| FET-based shunt architecture | Replaces PN-junction TVS with low-RDS(on) switch - reduces energy dissipation in silicon junction |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive fast transients in industrial environments |
| Low leakage | ≤600nA at 22V - avoids loading on 22V power rails or high-impedance signal paths |
| UL 94V-0 molding compound | Ensures flame-retardant reliability in enclosed industrial and portable equipment enclosures |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBUS lines in USB-C PD ports against lightning-induced surges and connector ESD. IC Role / Device Role / Timing Role: Primary shunt suppressor placed directly at connector, diverting transient energy to ground before reaching PD controller or load switch. Use Value: Maintains clamping ≤28V across temperature and current range - prevents latch-up or gate oxide damage in 28V-tolerant PD controllers. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient clamp limiting voltage seen by internal FET drain-source junction during surge events. Use Value: Clamping below 28V avoids exceeding the 30V absolute maximum rating of many integrated load switches, extending system reliability. |
| IoT Edge Node Power Rail Protection | Notebook/Tablet 22V System Bus Protection |
|
Use Scenario: Securing 22V auxiliary power inputs in battery-backed IoT gateways exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input rail, coordinated with upstream fusing and downstream DC-DC converters. Use Value: 40A surge rating and ±30kV ESD withstand enable single-device compliance with IEC 61000-4-2/4-5 in space-constrained edge nodes. |
Use Scenario: Protecting 22V system rails (e.g., display backlight or SSD power) in ultraportable notebooks and tablets. IC Role / Device Role / Timing Role: Compact DFN suppressor mounted adjacent to power connector or DC jack to minimize trace inductance. Use Value: 1.6×1.6mm footprint saves >50% board area vs. legacy SOT-23 TVS solutions while delivering superior clamping stability. |
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) | No functional difference - TDS2211P.C is Semtech's standard orderable variant; GS12142-INE3 is a qualified alternate marking | Select TDS2211P.C for direct Semtech channel sourcing; GS12142-INE3 offers equivalent performance with Aetrix supply chain continuity |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping, smaller 0.6×0.6mm package | Targeted at CC/SBU lines in USB-C, not VBUS - insufficient for 40A surge or 22V bus protection | Use only for auxiliary signal lines; not a functional replacement for GS12142-INE3 in power rail roles |
Compared with TDS2211P.C, GS12142-INE3 provides identical protection performance and footprint, enabling seamless BOM substitution. Versus uClamp2411ZA, it delivers 67% higher surge current rating and 2V lower clamping - critical for 22V power integrity where voltage margin is constrained.

FAQ
What is the maximum continuous operating voltage for GS12142-INE3?
The GS12142-INE3 has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC or RMS without significant leakage. This makes GS12142-INE3 suitable for protecting 22V power rails such as USB PD VBUS, industrial 24V systems (with margin), and notebook auxiliary supplies.
Does GS12142-INE3 require a thermal pad on the PCB?
No - GS12142-INE3 does not require an external thermal pad. Its FET-based architecture dissipates surge energy primarily through conduction rather than junction heating, and the datasheet explicitly states "no thermal pad is needed." Proper grounding of all GND pins (1–3) and short, low-inductance routing are more critical for performance than thermal copper.
Can GS12142-INE3 be used on high-speed data lines like USB SuperSpeed?
No - GS12142-INE3 is not intended for high-speed data lines. With 175pF junction capacitance, it would severely degrade signal integrity on USB 3.x or PCIe lanes. GS12142-INE3 is optimized for power and low-speed control lines (e.g., VBUS, CC, load switch enable); use RClamp3371ZC (<0.25pF) for SuperSpeed differential pairs.
How does GS12142-INE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS12142-INE3 maintains ~27.5–28V clamping from 24A to 40A and across –40°C to +125°C. This results from its active FET shunt architecture, which lowers effective on-resistance under surge - eliminating thermal derating concerns.
Is GS12142-INE3 compliant with RoHS and halogen-free standards?
Yes - GS12142-INE3 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 lead-free, supporting environmentally regulated industrial and consumer deployments without compliance risk.
