Product details
Overview
1N6074 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. It protects USB PD, Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the 1N6074 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, low dynamic resistance (20 mΩ), junction capacitance (175 pF at 22V), and DFN 1.6×1.6mm 6-lead layout compatibility with high-density USB and IoT designs.
Technical Context
The 1N6074 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 RDS(on) under surge.
It operates with three input terminals (pins 4–6) and three ground terminals (pins 1–3) in parallel configuration to maximize surge current handling and minimize parasitic inductance. The device is rated for 1120W peak pulse power and exhibits only 130–600 nA reverse leakage at 22V standoff.
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 at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - low enough for VBus line protection without signal integrity impact |
| Dynamic Resistance | 20 mΩ - enables flat clamping curve and minimizes voltage rise under increasing surge current |
| Package | DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead - supports ultra-compact placement near connectors with minimal PCB area |
Pinout & Package
1N6074 is housed in a Pb-free, RoHS-compliant DFN 1.6 mm × 1.6 mm × 0.55 mm package with exposed thermal pad not required; all six terminals are functional and must be connected for full 40A rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground | Parallel GND connections reduce inductance and enable full 40A surge current path to PCB ground plane |
| Pins 4, 5, 6 | Input / Protected Line | Parallel IN connections distribute surge current across three paths, lowering per-terminal current density and thermal stress |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28 V across 24–40A and −40°C to +125°C - eliminates derating uncertainty in thermal design |
| FET-based shunt architecture | Replaces PN-junction TVS with active switching - avoids linear VC = VBR + IPP×RDYN drift |
| Low dynamic resistance | 20 mΩ - reduces IR drop under surge, enabling tighter clamping than silicon avalanche diodes |
| High EFT immunity | ±4 kV (IEC 61000-4-4, 5/50 ns) - protects against repetitive fast transients in motor drives and industrial comms |
| Small footprint | 1.6 mm × 1.6 mm - saves >60% board space vs. SO-8 or SOT-23 TVS solutions with comparable ratings |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V–22V VBus lines in USB-C receptacles against lightning-induced surges and hot-plug ESD events. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 28V clamping at 40A and 125°C-well below typical 30V+ absolute max ratings of USB PD controllers like TUSB73x or STUSB4500. | Use Scenario: Safeguarding input pins of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics against 1kV/42Ω surges. IC Role / Device Role / Timing Role: Front-end transient clamp preventing gate oxide damage and overvoltage latch-up in integrated FETs. Use Value: Limits voltage seen by load switch input to ≤28V during 40A surge-below 30V damage threshold of most eFuse ICs. |
| IoT Edge Node Power Rail Protection | Notebook/Tablet DC-In Protection |
Use Scenario: Securing 22V-rated auxiliary power rails in battery-backed smart sensors exposed to ESD during field servicing. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS + MOV networks for compact, reliable rail clamping. Use Value: Delivers ±30kV ESD and 40A surge protection in 2.56 mm² footprint-enabling conformal coating and sealed enclosure designs. | Use Scenario: Protecting 20V DC-in ports in ultrabooks and tablets against accidental AC adapter misconnection or induced surges. IC Role / Device Role / Timing Role: Standalone high-energy suppressor placed before buck converter input stage. Use Value: Clamps transients to 28V while adding only 175 pF capacitance-no impact on 100 kHz–1 MHz input filter stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Standard unidirectional TVS diode; 35.1V clamping at 12.3A (8/20μs); higher RDYN causes rising VC with current | Limited to lower-energy surges; unsuitable for 40A IEC 61000-4-5 compliance without parallel devices | Select only if cost sensitivity outweighs clamping stability and surge rating requirements |
| TPD2E007 | Low-capacitance (1.5 pF) dual-channel ESD array; 12A peak pulse; 15V working voltage | Designed for data-line ESD only-not rated for 22V power rail or 40A surge protection | Use only for USB SS/DP/DM line protection; never as VBus substitute for 1N6074 |
Compared with SMAJ22A and TPD2E007, the 1N6074 uniquely combines 22V working voltage, 40A surge rating, and flat 28V clamping-making it the only single-device solution qualified for USB PD VBus and industrial load switch input protection where voltage margin and thermal stability are critical.

FAQ
What is the clamping voltage of the 1N6074 at 40A surge current?
The 1N6074 clamps at 27.6–28 V under 40A peak pulse current (8/20μs waveform), as specified in its electrical characteristics table. This value remains stable across −40°C to +125°C operating temperature, distinguishing it from conventional TVS diodes whose clamping rises with current and temperature. The 1N6074 achieves this via its FET-based shunt architecture and sub-20 mΩ dynamic resistance.
Can the 1N6074 be used to protect USB Type-C VBus lines?
Yes-the 1N6074 is explicitly validated for USB Type-C VBus protection in Semtech's application documentation. Its 22V working voltage matches the USB PD specification's 20V nominal / 22V max VBus, and its 28V clamping stays safely below the 30V+ absolute maximum ratings of common PD controllers. The 1N6074 is recommended alongside low-capacitance TVS devices like RClamp3371ZC for superspeed data lines.
How many pins does the 1N6074 have, and what is their function?
The 1N6074 has six pins in a DFN 1.6 mm × 1.6 mm package: pins 1–3 are dedicated ground terminals, and pins 4–6 are parallel input terminals for the protected line. All six pins must be soldered to achieve full 40A surge rating-splitting current across three GND and three IN paths lowers inductance and thermal stress. Pin 1 is marked with a laser dot.
Is the 1N6074 RoHS compliant and halogen free?
Yes-the 1N6074 is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is lead-free. These attributes are confirmed in the mechanical characteristics section of the official Semtech datasheet Rev 2.5.
What is the junction capacitance of the 1N6074, and why does it matter?
The 1N6074 exhibits 175 pF junction capacitance at 22 V reverse bias and 1 MHz, measured per its datasheet. This value is optimized for power rail protection: low enough to avoid destabilizing upstream DC-DC input filters or inducing excessive signal distortion on VBus, yet high enough to sustain robust 40A surge energy dissipation. It is not intended for high-speed data line use-those require sub-1 pF devices.
