Product details

Overview

GS9074ACNE3 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 24–40A, and 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable equipment.

For engineers reviewing the GS9074ACNE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for EOS-critical 22V bus protection.

Technical Context

The GS9074ACNE3 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 reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and junction capacitance of 175pF at 22V/1MHz. Its low 20mΩ dynamic resistance enables stable energy diversion without thermal runaway, making it suitable for high-reliability 22V power rail protection where traditional TVS devices exhibit rising clamping with current and temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction.
Clamping Voltage	27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surges.
Peak Pulse Current	40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD input stages.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements for connector-facing protection.
Dynamic Resistance	20mΩ (measured 1–40A, 8/20μs) - enables flat clamping response and minimizes voltage overshoot during fast-rising transients.
Junction Capacitance	175pF at 22V, 1MHz - low enough for 22V power rail protection without degrading signal integrity or causing instability in regulated supplies.

Pinout & Package

GS9074ACNE3 is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground return for surge current; all three pins must be connected to maximize current handling and minimize parasitic inductance.
4, 5, 6	IN	Protected line input (e.g., VBus); all three pins are internally tied and must be shorted externally for full 40A rating and optimal ESD coupling path.

Key Features

Feature	Design Value
Constant-clamp architecture	Clamping voltage stays within 27.5–28V across 24–40A and –40°C to +125°C - eliminates derating uncertainty in thermal or high-current designs.
FET-based shunt topology	Replaces pn-junction TVS with low-R_DS(on) MOSFET triggered by precision circuit - avoids thermal runaway and enables higher surge endurance than silicon avalanche diodes.
Low dynamic resistance	20mΩ enables minimal IR drop during surge - critical for maintaining safe voltage margin on 22V rails feeding sensitive PD controllers or load switches.
High EFT immunity	±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive burst noise in industrial motor drives and metering systems.

Applications

USB Type-C Power Delivery Bus Protection	Industrial Load Switch Input Protection
Use Scenario: Protecting the 20–22V VBus line in USB Type-C receptacles supporting Power Delivery up to 100W. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and USB PD controller or buck converter input. Use Value: Maintains clamping at ≤28V across full temperature range and surge current, preventing overvoltage damage to PD controllers rated for 24–28V absolute max.	Use Scenario: Shielding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways from lightning-induced surges. IC Role / Device Role / Timing Role: Front-end transient shunt that diverts surge energy before it reaches the load switch's internal FET drain. Use Value: Keeps clamping voltage below the load switch's drain-source breakdown (typically 30–40V), avoiding catastrophic failure during 1kV/42Ω IEC 61000-4-5 events.

Use Scenario: Securing 19–22V input rails of NVMe SSD enclosures or external HDD docks exposed to hot-plug and ESD events. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, upstream of DC-DC converters and PMICs. Use Value: Delivers 40A surge capability in 1.6×1.6mm footprint - saves >50% board area versus SOD-123 or SMA TVS solutions while improving clamping consistency.	Use Scenario: Safeguarding 20V input stages of ultrabooks and tablets with USB-C charging, especially where space-constrained layouts limit thermal mass. IC Role / Device Role / Timing Role: First-line defense against ESD and surge entering via USB-C port, placed adjacent to connector. Use Value: ±30kV ESD rating and stable 28V clamping ensure compliance with IEC 61000-4-2 Level 4 without requiring additional series impedance or filtering.

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 Semtech datasheet Rev 2.5 - confirmed pin-to-pin and functional replacement.	No difference; validated for identical USB PD, load switch, and industrial 22V rail use cases.	Select TDS2211P.C when sourcing directly from Semtech or authorized distributors with full traceability.
SMAJ22A	Standard unidirectional TVS diode; 22V standoff, 35.5V min clamping at 14.3A (8/20μs); no constant-clamp behavior - clamping rises with current and temperature.	Suitable only for lower-energy surges (<15A) or ambient-temperature-limited applications; cannot replace GS9074ACNE3 in 40A or high-temp designs.	Choose SMAJ22A only for cost-sensitive, non-industrial applications where clamping voltage margin >7V is acceptable and peak current ≤15A.

Compared with GS9074ACNE3, TDS2211P.C offers identical performance and drop-in compatibility, while SMAJ22A provides lower-cost surge suppression but lacks stable clamping, temperature resilience, and 40A capability - making it unsuitable for USB PD or industrial 22V rail protection where reliability is critical.

FAQ

What is the exact package type and dimensions of GS9074ACNE3?

GS9074ACNE3 uses a DFN-6 package with dimensions 1.6mm × 1.6mm × 0.55mm and a 0.5mm pitch. Pins 1–3 are GND; pins 4–6 are IN. All six terminals must be soldered - no thermal pad required - and PCB layout must connect all GND pins to a solid ground plane using multiple vias for optimal surge current handling.

Does GS9074ACNE3 meet IEC 61000-4-5 surge immunity standards?

Yes, GS9074ACNE3 is rated for 40A peak pulse current (8/20μs waveform), satisfying IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω, CS = 0.5μF) for unsymmetrical lines. Its 27.5–28V clamping voltage at 40A ensures protected circuits remain within safe operating limits during standardized surge testing.

How does GS9074ACNE3 differ from standard TVS diodes like SMAJ22A?

GS9074ACNE3 uses a triggered FET shunt architecture, delivering constant 27.5–28V clamping from 24A to 40A and –40°C to +125°C. In contrast, SMAJ22A is a pn-junction TVS with rising clamping (e.g., ~35.5V at 14.3A) and significant temperature drift - making GS9074ACNE3 superior for 22V USB PD and industrial applications demanding predictable protection.

Can GS9074ACNE3 protect both power and data lines?

GS9074ACNE3 is optimized for 22V power or high-current I/O lines (e.g., USB-C VBus, load switch inputs), not high-speed data lanes. Its 175pF capacitance is too high for USB SuperSpeed or DisplayPort lines - those require sub-0.3pF devices like RClamp3371ZC. GS9074ACNE3 should be used exclusively on power rails or low-frequency control signals.

What is the maximum operating temperature range for GS9074ACNE3?

GS9074ACNE3 is specified for continuous operation from –40°C to +125°C ambient temperature, with junction temperature rated up to +150°C. Its clamping voltage remains stable across this full range - a key advantage over standard TVS diodes whose clamping increases significantly above 85°C.
