Product details

Overview

GS1670AIBTE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB PD, Type-C VBus, and load switch inputs in industrial and portable electronics.

For engineers reviewing the GS1670AIBTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for minimal voltage overshoot, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards.

Technical Context

The GS1670AIBTE3 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 and across −40°C to +125°C due to decreasing R_DS(on) under surge.

It operates with a 22V reverse stand-off voltage (V_RWM) and 25–27.9V breakdown (V_BR), delivers 1120W peak pulse power, and exhibits only 175pF junction capacitance at 22V/1MHz - enabling use on high-speed power rails without signal integrity degradation.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - defines maximum continuous DC bus voltage it can protect without leakage or conduction.
Clamping Voltage	27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds during worst-case surges.
Peak Pulse Current	40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds smartphone/tablet ESD robustness requirements for exposed connectors.
Dynamic Resistance	20mΩ - enables flat clamping response and minimizes voltage rise ΔV = I_PP × R_DYN under fast transients.
Junction Capacitance	175pF at 22V/1MHz - low enough to avoid degrading power rail stability or coupling noise into adjacent analog circuits.

Pinout & Package

GS1670AIBTE3 is housed in a RoHS-compliant, halogen-free DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals are required for full 40A surge rating: three GND pins must be connected to a low-inductance ground plane via multiple vias, and three IN pins must be tied together to the protected line near the connector.

Pin/Terminal	Circuit Role	Design Meaning
Pins 1, 2, 3	GND	Common ground return path for surge current; all three must be connected to minimize inductance and maximize current sharing.
Pins 4, 5, 6	IN	Input node connected to protected 22V bus (e.g., USB PD VBus); parallel connection ensures uniform current distribution and thermal balance.

Key Features

Feature	Design Value
Constant-clamp architecture	Clamping voltage varies ≤0.5V from 24A to 40A and stays stable across −40°C to +125°C - eliminates derating uncertainty in thermal designs.
FET-based shunt topology	Replaces traditional TVS junctions with low-R_DS(on) MOSFET, reducing energy dissipation in silicon and improving reliability under repeated surges.
Low dynamic resistance	20mΩ measured between 1A–40A (8/20μs) - limits voltage overshoot to <1V above nominal clamp, critical for 3.3V/5V logic supply rail protection.
High EFT immunity	±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz bursts) - sustains operation during repetitive electrical fast transients in motor drives and PLCs.

Applications

USB Type-C Power Delivery Protection	Industrial Load Switch Input Protection
Use Scenario: Protecting the 20–22V VBus line of USB Type-C ports supporting up to 100W PD in notebooks, docking stations, and monitors. IC Role / Device Role / Timing Role: Primary high-energy EOS suppressor placed directly at the Type-C receptacle, clamping lightning-induced surges before they reach the PD controller and buck-boost converter.

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 functional specification, same DFN-6 package, identical marking code T22; GS1670AIBTE3 is Semtech's alternate orderable part number for TDS2211P.	No functional difference - used interchangeably in BOMs and layouts; both qualified to same AEC-Q200 stress tests and JEDEC moisture sensitivity level MSL1.	Select GS1670AIBTE3 for tape-and-reel delivery with standard 3,000-unit reels; select TDS2211P.C if sourcing from legacy distributor stock with different reel labeling.
uClamp2411ZA	24V working voltage, lower 24A IPP rating, higher 30V clamping at 24A, and 12pF capacitance - optimized for CC/SBU lines, not power rails.	Designed for low-capacitance data-line protection (CC, SBU), not 22V power bus protection; unsuitable for 40A surge handling or VBus clamping.	Use uClamp2411ZA only for auxiliary signal lines in USB Type-C; do not substitute for GS1670AIBTE3 on VBus or load switch inputs due to insufficient IPP and higher clamp.

Compared with TDS2211P, GS1670AIBTE3 offers identical electrical and mechanical performance with standardized packaging logistics; compared with uClamp2411ZA, it provides 67% higher surge current capability and 2.5× lower clamping voltage at rated current - making it the sole suitable option for 22V power rail EOS protection.

FAQ

What is the exact package type and dimensions of GS1670AIBTE3?

GS1670AIBTE3 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad. Pin pitch is 0.5mm, and the land pattern follows Semtech's recommended footprint in the TDS2211P datasheet - no thermal pad solder mask opening is required since energy is dissipated in the FET channel, not the die junction.

Does GS1670AIBTE3 meet IEC 61000-4-5 surge immunity standards?

Yes, GS1670AIBTE3 is rated for ±1kV (1.2/50μs voltage, 8/20μs current, RS = 42Ω) and 40A (8/20μs) per IEC 61000-4-5, satisfying Level 4 industrial surge immunity requirements. Its constant clamping behavior ensures compliance across the full operating temperature range without derating.

Can GS1670AIBTE3 be used to protect a 20V USB PD VBus line?

Yes, GS1670AIBTE3 is explicitly designed for 22V working voltage systems and is deployed in USB Type-C PD reference designs to protect 20V VBus lines. Its 27.5–28V clamping voltage at 40A ensures PD controllers (typically rated to 28–30V ABS MAX) remain within safe operating limits during surge events.

How does GS1670AIBTE3 differ from standard TVS diodes in clamping behavior?

Unlike TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS1670AIBTE3 uses a triggered FET shunt that maintains ~27.5–28V clamp from 24A to 40A and across −40°C to +125°C - eliminating design uncertainty caused by temperature- and current-dependent voltage overshoot in conventional solutions.

Is GS1670AIBTE3 pin-compatible with other Semtech TDS devices?

GS1670AIBTE3 shares the same DFN-6 pinout (Pins 1–3 = GND, Pins 4–6 = IN) and footprint as TDS2211P and is functionally identical. However, it is not pin-compatible with other TDS variants like TDS1211P (12V) or TDS3311P (33V), which share the same package but differ in voltage ratings and internal trigger thresholds.
