Product details
Overview
GS2993-INTE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or data lines, featuring ±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 - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the GS2993-INTE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specifications, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for 22V bus protection in high-reliability embedded and USB PD systems.
Technical Context
The GS2993-INTE3 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 with stable clamping performance, low leakage (<600nA at 22V), and minimal temperature drift in breakdown voltage (25–27.9V) and dynamic resistance (20mΩ). Its 175pF capacitance at 22V/1MHz supports USB PD and industrial I/O without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail operating ranges without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below 30V damage threshold of common PD controllers and load switches. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD ports. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB IF and industrial ESD requirements for connector-facing protection. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough to avoid signal distortion on 20V DC power rails and slow control lines. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Leakage Current | ≤600nA at 22V - ensures negligible standby power loss in battery-backed or energy-sensitive IoT nodes. |
Pinout & Package
GS2993-INTE3 is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined), lead-free finish, and UL 94V-0 molding compound.
| 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 power rail); parallel connection of all three pins ensures uniform current sharing and optimal clamping. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Delivers flat clamping voltage across full 24–40A surge range - avoids voltage runaway seen in standard TVS diodes. |
| Temperature-stable clamping | Maintains 27.5–28V clamping from –40°C to +125°C - eliminates thermal derating calculations for industrial deployments. |
| Low dynamic resistance | 20mΩ enables sub-1V overshoot during 100A/μs dV/dt events - critical for protecting sensitive gate drivers and PD controllers. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) supports repeated lightning-surge exposure in remote meters and outdoor IoT gateways. |
| Ultra-low leakage | ≤600nA at VRWM ensures <1μW standby dissipation - suitable for always-on battery-powered edge sensors. |

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 (T22), same tape-and-reel packaging (3,000/reel). | No functional difference - TDS2211P.C is the commercial-grade variant with identical performance and qualification level. | Select TDS2211P.C when sourcing from authorized distributors with standard lead times; GS2993-INTE3 is typically used for extended temperature or enhanced traceability programs. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping, smaller 1.0mm × 0.6mm SOD-323 package, 15pF capacitance. | Better suited for CC/SBU lines in USB-C; insufficient for 40A VBUS protection due to lower surge rating and higher clamping. | Use uClamp2411ZA only for low-capacitance, low-current signal-line protection - not a drop-in replacement for GS2993-INTE3 on power rails. |
Compared with TDS2211P.C and uClamp2411ZA, GS2993-INTE3 offers identical core protection performance to TDS2211P.C but may include extended test screening or lot traceability for automotive-adjacent industrial programs, whereas uClamp2411ZA serves distinct low-capacitance signal-line roles and cannot replace GS2993-INTE3 in 40A, 22V power rail applications.

FAQ
What is the exact package type and dimensions of GS2993-INTE3?
GS2993-INTE3 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad, Pb-free and RoHS-compliant finish, and UL 94V-0 flammability rating. Pin 1 is marked with a laser dot, and all six terminals are arranged in two rows (GND on pins 1–3, IN on pins 4–6).
Does GS2993-INTE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS2993-INTE3 is rated for 40A peak pulse current (8/20μs waveform) and ±1kV combination wave (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 ICs remain within safe operating voltage limits during testing.
How does GS2993-INTE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS2993-INTE3 uses a triggered FET shunt that maintains 27.5–28V clamping from 24A to 40A and across –40°C to +125°C - eliminating thermal and current-dependent voltage drift that compromises protection margins.
Can GS2993-INTE3 be used on USB-C superspeed differential pairs?
No, GS2993-INTE3 is not suitable for USB-C superspeed (TX/RX, SSTX/SSRX) lines due to its 175pF junction capacitance, which would distort high-speed signals. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); GS2993-INTE3 is intended exclusively for VBUS, CC, SBU, or power-rail protection.
What is the maximum continuous reverse leakage current for GS2993-INTE3 at 22V?
At VRWM = 22V and TA = 25°C, GS2993-INTE3 exhibits a maximum reverse leakage current of 600nA. This value increases with temperature but remains below 1μA across its full –40°C to +125°C operating range, ensuring minimal impact on system standby power.
