Product details

Overview

GS12141-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 stable 27.5–28V clamping across temperature and current range. Used in USB Type-C PD input protection to safeguard controllers from voltage overshoot.

For engineers reviewing the GS12141-INTE3Z datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (<20 mΩ), junction capacitance (175 pF @ 22V), thermal robustness (−40°C to +125°C), and DFN 1.6×1.6mm package integration for space-constrained interfaces.

Technical Context

The GS12141-INTE3Z uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing R_DS(on) under increasing surge current.

It operates with reverse stand-off voltage of 22V, breakdown at 25–27.9V (I_t = 1mA), and maintains <600 nA leakage at VRWM. Its 2Ω source impedance-compliant clamping (per IEC 61000-4-5 combination waveform) ensures predictable protection behavior in industrial and USB PD systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22 V - defines maximum continuous DC bus voltage it can protect without leakage or conduction.
Clamping Voltage	27.5–28 V @ 40A (8/20μs) - limits transient overvoltage seen by downstream ICs during lightning/surge events.
Peak Pulse Current	40 A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1 kV, RS = 42 Ω) on unsymmetrical lines.
ESD Withstand	±30 kV contact & air (IEC 61000-4-2) - enables robust handling of human-body-model ESD in portable and connector-facing designs.
Dynamic Resistance	20 mΩ - ensures minimal voltage rise under surge, critical for maintaining tight clamping across current range.
Junction Capacitance	175 pF @ 22 V, 1 MHz - impacts signal integrity on power rails; suitable for DC-biased bus protection, not high-speed data lines.
Operating Temp	−40°C to +125°C - guarantees stable clamping and leakage performance across automotive and industrial ambient conditions.

Pinout & Package

GS12141-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.

Pin/Terminal	Circuit Role	Design Meaning
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.
4, 5, 6	IN	Protected line input (e.g., VBUS or power rail); parallel connection of all three pins lowers effective trace inductance and improves surge response.

Key Features

Feature	Design Value
Constant clamping voltage	27.5–28 V across 24–40 A surge range - eliminates design margin uncertainty caused by TVS voltage drift with current/temperature.
FET-based shunt architecture	R_DS(on) << 0.1 Ω under surge - enables low-loss energy diversion and avoids thermal runaway common in junction-limited TVS devices.
Low dynamic resistance	20 mΩ - reduces voltage overshoot during fast-rising transients (e.g., ESD), improving system-level immunity.
High EFT immunity	±4 kV per IEC 61000-4-4 (5/50 ns, 5 kHz & 100 kHz) - protects against repetitive burst noise in industrial control and motor drive environments.
Space-efficient packaging	1.6 × 1.6 mm DFN - saves >50% board area vs. traditional SOT-23 or SOIC TVS solutions while supporting automated assembly.

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), manufactured by Semtech.	Same use cases: USB-C PD, load switch, industrial power rail protection.	Select TDS2211P.C if sourcing directly from Semtech's official distribution channel with full traceability and warranty coverage.
uClamp2411ZA	24V working voltage, lower 20A IPP rating, higher 33V clamping, smaller 0.6×0.3mm DFN package, optimized for CC/SBU lines-not rated for 40A bus protection.	Limited to low-current auxiliary lines (e.g., USB-C CC, SBU); unsuitable for VBUS or power rail protection.	Use uClamp2411ZA only for secondary signal-line protection; GS12141-INTE3Z remains required for primary 22V bus clamping.

Compared with TDS2211P.C, GS12141-INTE3Z offers identical protection performance but may differ in reel packaging or date-code labeling; compared with uClamp2411ZA, GS12141-INTE3Z provides 2× higher surge current rating and 5V lower clamping-making it the sole viable option for 22V power rail EOS hardening.

FAQ

What is the maximum continuous operating voltage for GS12141-INTE3Z?

The GS12141-INTE3Z has a reverse stand-off voltage (V_RWM) of 22 V, meaning it reliably blocks voltages up to this level during normal operation without significant leakage. Its breakdown voltage starts at 25 V (min), confirming safe margin for 22 V DC bus applications. This rating is validated across −40°C to +125°C ambient conditions.

Does GS12141-INTE3Z meet IEC 61000-4-5 surge immunity standards?

Yes, GS12141-INTE3Z is rated for 40 A peak pulse current (8/20 μs) and complies with IEC 61000-4-5 Level 4 (±1 kV, R_S = 42 Ω, C_S = 0.5 μF) for unsymmetrical lines. Its clamping voltage remains ≤28 V under these conditions, ensuring protected circuits stay within safe voltage limits during standardized surge testing.

How does GS12141-INTE3Z differ from standard TVS diodes in clamping behavior?

Unlike standard TVS diodes whose clamping voltage rises linearly with surge current (V_C = V_BR + I_PP × R_DYN), GS12141-INTE3Z uses a triggered FET architecture that maintains near-constant clamping (27.5–28 V) from 24 A to 40 A. This eliminates design margin uncertainty and improves protection predictability across temperature and current extremes.

Can GS12141-INTE3Z be used on high-speed data lines like USB SuperSpeed?

No, GS12141-INTE3Z is not suitable for USB SuperSpeed (TX/RX) or other high-frequency signal lines due to its 175 pF junction capacitance at 22 V, which would severely degrade signal integrity. It is intended exclusively for DC-biased power or low-speed control lines (e.g., VBUS, CC, SBU, load switch enable). For data lines, Semtech recommends RClamp3371ZC (≤0.25 pF).

What PCB layout practices are recommended for optimal performance of GS12141-INTE3Z?

Place GS12141-INTE3Z as close as possible to the protected connector. Connect all three IN pins (4, 5, 6) in parallel with a short, wide trace; similarly tie all three GND pins (1, 2, 3) to a solid ground plane using multiple vias. Avoid thermal pads-energy is dissipated internally. This minimizes parasitic inductance and ensures full 40 A surge capability.
