Product details

Overview

GS3590-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 maintains a stable 27.5–28V clamping voltage 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 downstream controllers.

For engineers reviewing the GS3590-INTE3Z datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, dynamic resistance (<20 mΩ), junction capacitance (175 pF at 22V), and DFN 1.6×1.6mm 6-lead package compatibility with high-density USB PD and industrial load-switch layouts.

Technical Context

The GS3590-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 conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing R_DS(on) under increasing current - not fixed dynamic resistance.

It operates with reverse stand-off voltage (V_RWM) of 22V, breakdown voltage (V_BR) of 25–27.9V, and exhibits <600 nA leakage at V_RWM. Its functional architecture enables stable 27.5–28V clamping at both 24A and 40A (1.2/50μs + 8/20μs combination waveform, R_S = 2Ω), independent of ambient temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RWM	22 V - Maximum continuous operating voltage before clamping initiates; matches USB PD 20V nominal + margin.
V_C @ 40A	27.5–28 V - Clamping voltage during worst-case 40A surge; stays within safe margin below typical 28–30V IC damage thresholds.
R_DYN	20 mΩ - Low dynamic resistance ensures minimal voltage rise under surge; enables flat clamping curve.
C_J	175 pF @ 22V, 1MHz - Capacitance compatible with DC power rails and low-speed control lines; not suitable for >100MHz signal paths.
I_PP	40 A (8/20μs) - Sustains industrial-level surge events per IEC 61000-4-5; supports ±1kV line surge testing (R_S = 42Ω).
ESD Rating	±30 kV contact & air (IEC 61000-4-2) - Full system-level ESD robustness without external staging.
T_OP	−40°C to +125°C - Rated for extended industrial and automotive under-hood environments without derating.

Pinout & Package

GS3590-INTE3Z is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads and UL 94V-0 molding compound. The package features three dedicated ground terminals and three parallel input terminals to minimize parasitic inductance and maximize surge current handling.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground return for surge current; all three must be connected to low-inductance ground plane for rated 40A performance.
4, 5, 6	IN	Parallel-connected input terminals for protected line (e.g., V_Bus); equal current sharing reduces thermal stress and improves reliability.

Key Features

Feature	Design Value
FET-based transient shunting	Replaces traditional TVS with active clamping: eliminates linear V_C vs. I_PP drift and enables stable 27.5–28V clamping across full 1–40A range.
Temperature-invariant clamping	Clamping voltage variation <0.5V from −40°C to +125°C - removes thermal derating uncertainty in industrial and automotive deployments.
Low dynamic resistance	20 mΩ measured between 1A and 40A (8/20μs) - minimizes IR drop during surge, preserving voltage margin for protected ICs.
High-energy surge rating	1120 W peak pulse power (8/20μs) - supports repeated lightning-surge transients in metering and remote IoT equipment.
DFN space optimization	1.6×1.6mm footprint saves >50% board area vs. SO-8 or SOT-23 alternatives - critical for compact USB Type-C connectors and load switches.

Applications

Use Value: Eliminates need for multi-stage protection (TVS + MOV + filter), reducing BOM count and PCB area while guaranteeing coordinated clamping behavior.	Use Scenario: Protecting 22V backup power supplies in NVMe SSDs and enterprise storage controllers against power-rail transients during hot-swap or brownout recovery. IC Role / Device Role / Timing Role: Fast-acting shunt that diverts energy away from sensitive PMICs and flash memory power regulators during supply-line disturbances. Use Value: 175 pF junction capacitance avoids signal integrity issues on DC rails, while 40A rating handles capacitor discharge surges without degradation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TDS2211P	Identical electrical specs, same DFN 1.6×1.6mm package, identical pinout (3×GND / 3×IN), same Semtech manufacturing and qualification.	No functional difference; GS3590-INTE3Z is a valid alternate marking for TDS2211P per Semtech documentation and distributor cross-reference data.	Select GS3590-INTE3Z for availability continuity or TDS2211P for legacy design documentation alignment.
uClamp2411ZA	24V V_RWM, lower 24A I_PP, higher 30V clamping, smaller 1.0×1.0mm 2-pin DFN, no multi-pin parallel architecture.	Targeted at CC/SBU lines in USB-C, not main V_Bus; insufficient for 40A surge or 22V bus protection.	Use only for auxiliary signal lines; not a functional replacement for GS3590-INTE3Z in power rail roles.

Compared with TDS2211P, GS3590-INTE3Z offers identical protection performance and layout compatibility, making it a direct sourcing alternative; versus uClamp2411ZA, it provides 67% higher surge rating and 2V lower clamping - essential for 22V power rail integrity.

FAQ

What is the exact package type and dimensions of GS3590-INTE3Z?

GS3590-INTE3Z uses a DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with six leads. Pins 1–3 are ground terminals, and pins 4–6 are parallel-connected input terminals. The package is Pb-free, halogen-free, RoHS/WEEE compliant, and carries UL 94V-0 flammability rating. This footprint matches Semtech's TDS2211P and enables high-current PCB routing with minimal inductance.

Does GS3590-INTE3Z require external bias or control signals to operate?

No, GS3590-INTE3Z is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET that activate automatically when transient voltage exceeds the breakdown threshold (~25–27.9V). No external power, enable pins, or configuration are needed - GS3590-INTE3Z functions as a two-terminal shunt protector once installed across the protected line and ground.

How does GS3590-INTE3Z differ from standard TVS diodes in clamping behavior?

Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (V_C = V_BR + I_PP × R_DYN), GS3590-INTE3Z maintains near-constant clamping (27.5–28V) from 1A to 40A due to its FET-based architecture and decreasing R_DS(on). This eliminates thermal derating concerns and ensures predictable protection margins across temperature and surge magnitude - a key advantage confirmed in GS3590-INTE3Z test data.

Can GS3590-INTE3Z be used on high-speed data lines like USB SS or PCIe?

No, GS3590-INTE3Z is not suitable for high-speed data lines. Its 175 pF junction capacitance at 22V would severely degrade signal integrity on SuperSpeed (5+ Gbps), PCIe, or HDMI paths. It is specifically designed for DC power rails and low-speed control lines (e.g., USB PD communication, load switch enable). For data lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25 pF), not GS3590-INTE3Z.

Is GS3590-INTE3Z pin-compatible with other Semtech TDS devices?

GS3590-INTE3Z shares the same 6-pin DFN 1.6×1.6mm package and pin configuration (3×GND / 3×IN) as TDS2211P and is functionally identical. However, it is not pin-compatible with other TDS variants such as TDS3301P (33V, different pinout) or TDS1201P (12V, same package but distinct internal topology). Always verify V_RWM, I_PP, and pin mapping before substitution - GS3590-INTE3Z is only interchangeable with TDS2211P.
