Product details
Overview
JANTX1N3611 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection on 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 - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTX1N3611 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for 22V bus protection in high-reliability embedded and industrial systems.
Technical Context
JANTX1N3611 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 across 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
The device operates from –40°C to +125°C with stable 27.5–28V clamping at 40A, 22V reverse stand-off voltage, and 175pF junction capacitance at 22V/1MHz - enabling robust protection without thermal derating penalties seen in standard TVS devices.
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 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements with 2Ω source impedance. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - eliminates need for secondary ESD stages in exposed connector interfaces. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during high-current transients, minimizing energy dissipation in the device itself. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with medium-speed data/power lines (e.g., USB PD VBUS, load switch inputs) without signal integrity degradation. |
| Operating Temperature | –40°C to +125°C - supports deployment in automotive-adjacent industrial equipment and outdoor IoT gateways. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish, tape-and-reel packaging (3,000 units/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current handling and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS, load switch VIN); parallel connection of all three pins ensures uniform current sharing and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A (8/20μs), eliminating thermal runaway risk and simplifying margin analysis vs. traditional TVS. |
| Low dynamic resistance | 20mΩ enables <1V IR drop at 40A, shifting surge energy dissipation away from the protection device and into PCB traces/GND plane. |
| High-temperature stability | Clamping remains 27.5–28V from –40°C to +125°C - no derating required for industrial ambient conditions. |
| Compact footprint | 1.6mm × 1.6mm DFN saves >60% board area vs. comparable SO-8 or SOT-23 TVS solutions while maintaining 1120W peak power capability. |
| Integrated trigger circuit | Eliminates external biasing or timing components; activates shunt FET within nanoseconds of overvoltage detection. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB-C ports supporting up to 20V/5A PD negotiation, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end transient suppressor placed directly at the connector, clamping fast-rising EOS events before reaching PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping across temperature and current range - prevents false triggering or latch-up in PD controllers rated for ≤30V absolute max. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Surge shunt element that diverts 40A transients away from the load switch's internal MOSFET drain-source junction. Use Value: Keeps clamping voltage below the 30V damage threshold of typical 25V-rated load switch FETs, preventing catastrophic failure during 1.2/50μs surges. |
| IoT Gateway Power Bus Protection | Storage Device DC Power Rail Protection |
|
Use Scenario: Securing 22V auxiliary power rails in edge IoT gateways subjected to field ESD and induced surges from nearby AC mains switching. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, replacing multi-stage TVS+MOV designs with single-component reliability. Use Value: Delivers ±30kV ESD immunity and 40A surge handling in minimal space - reduces BOM count and improves long-term field reliability vs. aging MOVs. |
Use Scenario: Protecting 22V supply inputs of NVMe SSD enclosures or enterprise HDD backplanes against hot-plug transients and system-level coupling. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) suppressor placed upstream of PMIC regulators and storage controllers. Use Value: Prevents voltage overshoot beyond 28V during 8/20μs surges - avoids regulator shutdown or NAND flash corruption without adding signal-path capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P.C | Identical electrical specs, same DFN-6 package, commercial-grade (-40°C to +85°C) variant with identical pinout and marking (T22XX). | Not qualified to MIL-PRF-19500 JANTX level; lacks extended temperature range and screening for military/aerospace use. | Select JANTX1N3611 for programs requiring MIL-STD-883 Class B screening, extended temperature validation, or DoD traceability. |
| Littelfuse SP3022-01FTG | TVS diode array with 22V working voltage, ±30kV ESD, but 33V clamping at 24A (8/20μs); higher dynamic resistance (~0.5Ω) causes voltage rise with current. | Limited to lower-energy surges; clamping increases with temperature and current - less suitable for sustained 40A industrial surges. | Choose only if cost sensitivity outweighs clamping stability and temperature performance requirements. |
Compared with JANTX1N3611, TDS2211P.C offers identical protection performance in commercial environments, while SP3022-01FTG provides lower-cost TVS-based protection at the expense of clamping consistency and high-current surge capability.

FAQ
What is the maximum continuous operating voltage for JANTX1N3611?
JANTX1N3611 has a reverse stand-off voltage (VRWM) of 22V, meaning it can reliably block up to 22V DC or RMS AC continuously without significant leakage or conduction. This makes JANTX1N3611 suitable for 20V USB PD VBUS lines and other 22V-rated industrial power rails where sustained voltage exposure occurs.
How does JANTX1N3611 achieve stable clamping voltage across varying surge currents?
JANTX1N3611 achieves stable clamping via a surge-rated FET activated by an integrated trigger circuit. As peak pulse current rises from 24A to 40A (8/20μs), the FET's RDS(on) decreases, counteracting voltage rise - resulting in only 0.5V variation in clamping (27.5–28V). This contrasts with TVS diodes whose clamping rises linearly with current due to fixed dynamic resistance.
Is JANTX1N3611 pin-compatible with standard TVS diodes in DFN-6 packages?
No - JANTX1N3611 uses a unique 3-pin input / 3-pin ground configuration (Pins 4–6 = IN, Pins 1–3 = GND), unlike typical unidirectional TVS diodes in DFN-6 that assign dedicated anode/cathode pins. Direct replacement requires PCB layout revision to accommodate parallel input and ground connections per functional group.
What is the junction capacitance of JANTX1N3611 and how does it affect signal integrity?
JANTX1N3611 exhibits 175pF junction capacitance at 22V and 1MHz. This value is appropriate for DC power lines and medium-speed control signals (e.g., load switch enable, PD communication lines), but not for high-speed differential pairs like USB SS or PCIe - where sub-0.5pF devices are required. Its capacitance does not degrade VBUS regulation or cause measurable ripple in 22V power distribution networks.
Does JANTX1N3611 require external components such as bias resistors or timing capacitors?
No - JANTX1N3611 integrates the trigger circuit, drive logic, and shunt FET into a single monolithic die. It operates autonomously with only two external connections: the protected line (Pins 4–6) and system ground (Pins 1–3). No external biasing, RC networks, or enable signals are needed, simplifying layout and reducing BOM count.
