Product details
Overview
JANTXV1N5418.TR 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), and stable 27.5–28V clamping across temperature and current range. It protects USB Type-C power delivery buses, load switch inputs, and industrial I/O interfaces using a surge-rated FET shunt architecture.
For engineers reviewing the JANTXV1N5418.TR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A transients, DFN-6 package thermal and layout constraints, 175pF junction capacitance at 22V, and compatibility with 22V working voltage systems requiring robust ±1kV IEC 61000-4-5 surge immunity.
Technical Context
The JANTXV1N5418.TR implements a precision-triggered shunt FET architecture - not a conventional TVS diode - enabling near-constant clamping voltage (27.5–28V) over 24–40A peak pulse current and −40°C to +125°C operating temperature. Its dynamic resistance is 20mΩ, measured between 1A and 40A (8/20μs), resulting in minimal voltage rise during surge conduction.
Unlike standard TVS devices whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), the JANTXV1N5418.TR maintains clamping close to its trigger circuit breakdown voltage due to decreasing RDS(on) as current increases. This architecture delivers superior protection margin for 22V systems such as USB PD controllers and industrial load switches where voltage overshoot must remain below 28V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream 22V-rated ICs (e.g., USB PD controllers) remain below absolute max ratings during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω) and industrial surge requirements. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 ESD immunity for handheld and exposed interface applications. |
| Junction Capacitance | 175pF at VR = 22V, f = 1MHz - low enough for 22V power rail protection but not suitable for high-speed data lines (e.g., USB SS). |
| Dynamic Resistance | 20mΩ - enables flat clamping response; contributes to <0.8V voltage rise from 1A to 40A conduction. |
| Reverse Leakage | 130–600nA at 22V - negligible power loss in always-on protection configurations. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound. Thermal pad not required; energy dissipated in silicon FET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to maximize current handling and minimize inductance. |
| 4, 5, 6 | IN | Protected input terminal - connects to 22V bus or line; all three pins must be tied together externally for full 40A rating and optimal ESD coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A and −40°C to +125°C - eliminates derating uncertainty in thermal or high-current designs. |
| Surge-rated FET shunt element | Replaces traditional pn-junction TVS; achieves 20mΩ dynamic resistance and avoids thermal runaway under repeated surges. |
| Low-impedance ground path design | Three dedicated GND pins reduce parasitic inductance - critical for sub-10ns ESD rise time suppression and PCB layout robustness. |
| High-energy EOS protection | 1120W peak pulse power (8/20μs) - sustains multi-event surge stress without parameter shift or failure. |
Applications
| USB Type-C Power Delivery Bus 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 EOS shunt protector placed directly at connector, clamping transients before reaching PD controller and load switch. Use Value: Maintains clamping at ≤28V across temperature - prevents damage to 22V-rated PD controllers where conventional TVS would exceed 35V at 125°C. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Enables use of cost-optimized load switches without requiring higher-voltage, derated components - preserves system BOM efficiency. |
| 22V Industrial I/O Line Protection | Notebook/Tablet DC Power Rail Protection |
Use Scenario: Securing 22V auxiliary rails in programmable logic controllers (PLCs), motor drives, and sensor hubs subject to field wiring surges. IC Role / Device Role / Timing Role: Single-device solution for IEC 61000-4-5 Level 4 (±1kV) compliance on unidirectional power lines. Use Value: Eliminates need for series impedance or multi-stage protection - reduces component count and board space vs. TVS+MOV stacks. |
Use Scenario: Protecting 20–22V DC-in rails in ultraportables and 2-in-1 tablets against adapter fault transients and ESD coupling from chassis. IC Role / Device Role / Timing Role: Low-profile, high-reliability clamp integrated into compact power entry circuit near barrel jack or USB-C port. Use Value: DFN-6 footprint (1.6×1.6mm) saves >60% area vs. SOT-23 TVS alternatives while delivering superior clamping consistency. |
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 | Same die, commercial-grade (−40°C to +85°C), identical electrical specs and pinout; differs only in temperature rating and screening. | Not qualified for military/aerospace extended temp or reliability testing; unsuitable for JANTXV-level programs. | Select JANTXV1N5418.TR when MIL-PRF-19500/565 qualification, extended temperature operation (−55°C to +150°C), or hermetic packaging traceability is required. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; clamping rises with current and temperature (no constant-clamp behavior). | Lacks FET-based architecture - cannot maintain low clamping at 40A or high temperature; higher leakage (≤1μA). | Choose SMAJ22A only if cost sensitivity outweighs clamping performance, and surge duty is infrequent/low-energy. |
Compared with TDS2211P.C and SMAJ22A, JANTXV1N5418.TR provides guaranteed military-grade screening, full −55°C to +150°C junction/storage temperature support, and stable 28V clamping at 40A - making it the sole option for high-reliability 22V rail protection where thermal and surge margin are non-negotiable.

FAQ
What is the primary protection function of the JANTXV1N5418.TR?
The JANTXV1N5418.TR functions as a transient diverting suppressor that uses a precision-triggered surge-rated FET to shunt high-energy EOS events (ESD, lightning, EFT) away from sensitive downstream circuitry. Unlike TVS diodes, it maintains a stable ~28V clamping voltage across its full 40A peak pulse current range and −55°C to +150°C operating temperature, making JANTXV1N5418.TR ideal for protecting 22V power rails in mission-critical applications.
Does the JANTXV1N5418.TR require a thermal pad on the PCB?
No, the JANTXV1N5418.TR does not require a thermal pad. Its DFN-6 package dissipates surge energy within the silicon FET structure, and the datasheet explicitly states "no thermal pad is needed." Instead, robust grounding via all three GND pins (1, 2, 3) and low-inductance routing - including multiple vias to the ground plane - is essential to achieve rated 40A performance and fast ESD response. This design simplifies layout versus thermally enhanced TVS solutions.
How does the JANTXV1N5418.TR differ from standard TVS diodes like SMAJ22A?
The JANTXV1N5418.TR uses a controlled-FET shunt architecture, delivering constant clamping (~28V) across 24–40A and temperature, whereas SMAJ22A - a conventional TVS - exhibits rising clamping (to ~35.5V at 12.3A) that worsens with temperature. JANTXV1N5418.TR also offers ±30kV ESD, 1120W peak power, and military-grade screening per MIL-PRF-19500/565 - capabilities SMAJ22A lacks. These differences make JANTXV1N5418.TR suitable for high-reliability 22V systems where voltage margin is tight.
Can the JANTXV1N5418.TR be used on high-speed data lines like USB SuperSpeed?
No, the JANTXV1N5418.TR is not suitable for USB SuperSpeed (SS), DP, or DM lines. Its 175pF junction capacitance at 22V is optimized for power rail or low-speed I/O protection, not signal integrity preservation. For high-speed data lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). JANTXV1N5418.TR is intended exclusively for 22V bus protection - such as VBUS in USB-C PD - where bandwidth is not a constraint.
What is the recommended PCB layout for optimal performance of the JANTXV1N5418.TR?
Place the JANTXV1N5418.TR as close as possible to the protected connector or entry point. Connect all three IN pins (4, 5, 6) together with a short, wide trace to the protected line, and tie all three GND pins (1, 2, 3) directly to a solid ground plane using ≥3 vias. Avoid stubs or splits in the GND path. This minimizes parasitic inductance, ensuring effective suppression of fast-rising ESD (sub-10ns) and high-current surges - a requirement confirmed in the JANTXV1N5418.TR datasheet layout guidelines.
