Product details
Overview
GS1582-IBE3 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 its full current and temperature range (–40°C to +125°C). It is used in USB Type-C PD bus protection where low, temperature-invariant clamping prevents damage to voltage-sensitive controllers.
For engineers reviewing the GS1582-IBE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over temperature, dynamic resistance (<20 mΩ), junction capacitance (175 pF), and DFN 1.6×1.6mm 6-lead package compatibility with high-density USB PD and industrial load-switch layouts.
Technical Context
The GS1582-IBE3 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 because the FET's RDS(on) collapses under surge, minimizing voltage rise with increasing IPP.
It operates with reverse stand-off voltage (VRWM) of 22V, breakdown voltage (VBR) of 25–27.9V, and clamps at 27.5–28V at both 24A and 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω). Its 175 pF junction capacitance and <600 nA leakage at 22V support robust signal integrity in high-speed bus applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A - ensures downstream ICs (e.g., USB PD controllers) remain below absolute maximum ratings during surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds common system-level ESD test requirements for end-equipment certification |
| Dynamic Resistance | 20 mΩ - enables low-voltage overshoot and minimal power dissipation during high-current transients |
| Junction Capacitance | 175 pF at 22V, 1MHz - compatible with USB Type-C VBUS protection without degrading power delivery signaling integrity |
| Operating Temperature | –40°C to +125°C - supports deployment in automotive cabin, industrial control, and outdoor IoT environments |
Pinout & Package
GS1582-IBE3 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current-handling capability and minimize parasitic inductance |
| Pins 4, 5, 6 | IN | Protected line input (e.g., USB PD VBUS); parallel connection of all three pins reduces trace inductance and improves high-frequency transient response |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A - eliminates need for derating at elevated temperatures or high surge currents |
| FET-based shunt topology | RDS(on)-dominated conduction - dissipates energy in channel rather than PN junction, enabling higher reliability and thermal stability |
| Low dynamic resistance | 20 mΩ - limits voltage overshoot during fast-rising transients (e.g., ESD), improving protection margin for sensitive gate oxides |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive burst noise in motor drives and industrial PLCs |
| Space-efficient packaging | 1.6 mm × 1.6 mm footprint - saves >60% board area vs. legacy SO-8 or SOT-23 TVS solutions while maintaining 40A surge rating |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the 20–22V VBUS line in USB Type-C receptacles supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed adjacent to the connector, clamping surges before they reach the PD controller or load switch. Use Value: Maintains 27.5–28V clamping across –40°C to +125°C, preventing false overvoltage shutdowns and ensuring PD communication integrity during surge events. |

IC Role / Device Role / Timing Role: Front-end transient suppressor that diverts lightning-induced surges and inductive kickback away from the load switch's internal FET. Use Value: Keeps clamping voltage below the load switch's absolute maximum drain-source voltage rating, avoiding catastrophic failure during 1kV/42Ω IEC 61000-4-5 tests. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
|
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors and gateway devices exposed to field ESD and conducted noise. IC Role / Device Role / Timing Role: Single-component solution for EOS suppression on always-on power inputs, replacing multi-device TVS+RC networks. Use Value: Delivers ±30kV ESD immunity and 40A surge handling in a 1.6 mm² footprint, enabling compact, certified designs for FCC/CE Class B emissions compliance. |
Use Scenario: Protecting 22V supply rails in NVMe SSD enclosures and enterprise storage backplanes subject to hot-plug transients and system-level surges. IC Role / Device Role / Timing Role: High-energy clamping device placed at board edge to absorb coupling from adjacent high-speed data lanes or power sequencing events. Use Value: Stable 28V clamping ensures SSD controller and PMIC inputs remain within safe operating area during 8/20μs surges, reducing field return rates. |
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), and same tape-and-reel packaging (3,000/reel). | No functional difference; TDS2211P.C is the standard Semtech orderable part number for this device. | Select TDS2211P.C when sourcing directly from Semtech or authorized distributors with full traceability and warranty coverage. |
| uClamp2411ZA | 24V working voltage, lower 24A peak pulse rating, 28V clamping, and 120 pF capacitance - optimized for CC/SBU lines, not main VBUS. | Designed for low-capacitance, low-current signal-line protection; insufficient for 40A VBUS surge handling. | Use uClamp2411ZA only for auxiliary USB Type-C lines (CC/SBU); not a substitute for GS1582-IBE3 in main power rail protection. |
Compared with TDS2211P.C (identical specification) and uClamp2411ZA (lower surge rating, different application scope), GS1582-IBE3 provides verified 40A/22V protection in production-grade packaging - making it the optimal choice for high-reliability VBUS front-end suppression where clamping stability and thermal robustness are critical.

GS1582-IBE3 uses a DFN (Dual Flat No-lead) package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 terminals. Pins 1–3 are GND; pins 4–6 are the protected input node. The package is Pb-free, halogen-free, RoHS/WEEE compliant, and rated UL 94V-0 for flammability. This matches Semtech's official TDS2211P.C mechanical specifications.
Does GS1582-IBE3 meet IEC 61000-4-5 surge immunity requirements?
Yes, GS1582-IBE3 is rated for 40A peak pulse current with an 8/20μs waveform per IEC 61000-4-5, and also supports ±1kV unsymmetrical surge testing (1.2/50μs voltage, 8/20μs current, RS = 42Ω). Its 27.5–28V clamping voltage ensures protected circuits remain within safe operating limits during these standardized industrial surge events.
How does GS1582-IBE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS1582-IBE3 uses a triggered FET architecture that maintains clamping voltage within 0.5V from 24A to 40A. This near-constant clamping is confirmed across –40°C to +125°C, eliminating thermal derating concerns present in traditional TVS solutions.
Can GS1582-IBE3 be used for USB Type-C VBUS protection alongside RClamp3371ZC?
Yes - GS1582-IBE3 is specifically recommended for USB Type-C VBUS (20–22V) protection, while RClamp3371ZC (0.25pF) handles high-speed SuperSpeed differential pairs. Semtech's reference design positions GS1582-IBE3 at the connector for bulk surge suppression, enabling coexistence with low-capacitance TVS devices on data lines without compromising signal integrity or surge margin.
