Product details
Overview
GS12081-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. Used in USB Type-C PD input protection, it replaces conventional TVS diodes where low, flat clamping is critical to safeguard sensitive controllers.
For engineers reviewing the GS12081-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 GS12081-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 standard TVS diodes, its clamping voltage remains nearly constant - not linearly increasing - due to decreasing RDS(on) under surge, yielding ~27.6V at both 24A and 40A (1.2/50μs + 8/20μs combo waveform, RS = 2Ω).
It operates from −40°C to +125°C with <20mΩ dynamic resistance (measured 1A–40A, 8/20μs), 130–600nA reverse leakage at 22V, and 175pF capacitance at 1MHz/22V. Its functional architecture isolates protection energy dissipation into the FET channel rather than the junction, enabling superior thermal stability versus conventional TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo) - ensures protected 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 inputs |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements for connector-facing protection |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces |
| Dynamic Resistance | 20mΩ - enables flat clamping by minimizing IR drop increase under rising surge current |
| Operating Temperature | −40°C to +125°C - supports deployment in extended-temperature industrial and automotive under-hood environments |
Pinout & Package
GS12081-INTE3Z is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound. The package features exposed thermal pad-less construction; all pins must be soldered for rated surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current - all three pins must be connected to minimize inductance and maximize 40A handling |
| 4, 5, 6 | IN | Protected line input - connects directly to VBus or power/data line; all three pins are internally paralleled for current sharing and low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces junction-limited TVS with active shunt FET, enabling stable clamping independent of surge amplitude |
| Constant clamping voltage | 27.5–28V across full 24–40A surge range and −40°C to +125°C - eliminates derating uncertainty in thermal design |
| Low dynamic resistance | 20mΩ - minimizes voltage overshoot during fast-rising transients and improves energy-handling margin |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive burst noise in motor drives and PLCs |
| DFN-6 space efficiency | 1.6mm × 1.6mm footprint - saves >50% board area vs. SO-8 or SOT-23 TVS solutions rated for comparable surge energy |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C PD ports against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary high-energy EOS suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.6V clamping at 40A - well below typical 30V absolute max rating of PD controllers - preventing latch-up or gate oxide damage. |

IC Role / Device Role / Timing Role: High-reliability clamping device placed at board edge before power sequencing ICs or buck converters. Use Value: 175pF capacitance avoids interference with 22V rail monitoring circuits, while ±30kV ESD rating ensures robustness during handling and field service. |
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, DFN-6 package - differs only in tape-and-reel packaging (3,000 pcs/reel vs. GS12081-INTE3Z's unspecified reel count) | No functional difference; validated for identical USB PD, load switch, and industrial use cases | Select TDS2211P.C if standard Semtech reel quantity and marking (T22 + date code) are required for procurement alignment |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 33V clamping at 24A, smaller 0.65mm × 0.65mm DFN-2 package | Targeted at CC/SBU lines in USB-C, not main VBus - insufficient for 40A surge or 22V rail protection | Use uClamp2411ZA only for auxiliary signal-line protection; not a functional substitute for GS12081-INTE3Z's 22V/40A power-rail role |
Compared with TDS2211P.C, GS12081-INTE3Z offers identical protection performance but may differ in reel configuration or traceability labeling; compared with uClamp2411ZA, GS12081-INTE3Z provides 67% higher surge current rating and 5.5V lower clamping - making it the sole suitable option for 22V power rail EOS hardening.

FAQ
What is the maximum continuous operating voltage for GS12081-INTE3Z?
The GS12081-INTE3Z has a reverse stand-off voltage (VRWM) of 22V, meaning it is rated for continuous operation up to 22V DC on the protected line. Exceeding this voltage risks increased leakage current and potential device degradation. This rating aligns with USB PD 3.0 VBus levels and industrial 24V nominal systems operating at reduced voltage margins.
How does GS12081-INTE3Z achieve stable clamping voltage across temperature?
GS12081-INTE3Z achieves stable clamping by using a surge-rated FET as the conduction element, activated via a precision trigger circuit. As surge current increases, the FET's RDS(on) decreases, counteracting IR rise - resulting in clamping voltage of 27.5–28V from −40°C to +125°C. This contrasts with TVS diodes, whose clamping rises ~0.1V/°C due to fixed dynamic resistance.
Can GS12081-INTE3Z replace a standard TVS diode in a 22V power rail design?
Yes - GS12081-INTE3Z is engineered as a direct functional upgrade to conventional TVS diodes in 22V applications. Its 40A surge rating, ±30kV ESD immunity, and flat 27.6V clamping at full current provide superior protection margin. However, PCB layout must follow DFN-6 guidelines: all GND (pins 1–3) and IN (pins 4–6) pins must be shorted together with low-inductance traces and multiple vias to ground plane.
What is the junction capacitance of GS12081-INTE3Z and why does it matter?
The GS12081-INTE3Z exhibits 175pF junction capacitance at 22V and 1MHz. This value is optimized for power rail protection - low enough to avoid loading 22V monitoring circuits or causing instability in feedback loops, yet higher than signal-line TVS devices (e.g., <0.3pF), reflecting its purpose as a high-energy shunt rather than high-speed data-line clamp.
Is GS12081-INTE3Z compliant with RoHS and halogen-free standards?
Yes - GS12081-INTE3Z is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound carries UL 94V-0 flammability rating, and lead finish is lead-free. These compliance attributes are confirmed in Semtech's official datasheet Rev 2.5 and supported by material declarations available through authorized distributors.
