Product details
Overview
JANTX1N6079 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 - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTX1N6079 datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DFN 1.6×1.6mm, 6-lead), validated terminal roles (IN/GND), real-world clamping stability data, and two confirmed alternative surge protectors with documented parameter divergence.
Technical Context
JANTX1N6079 employs a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under surge conditions.
The device operates across –40°C to +125°C, maintains ≤600nA reverse leakage at 22V, and delivers 20mΩ dynamic resistance (measured 1–40A, 8/20μs). Its 175pF junction capacitance at 22V/1MHz supports low-distortion protection on moderate-speed bus lines without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - stays below 30V damage threshold of common load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - satisfies IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD test mandates. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with USB Type-C VBUS and DC power line protection without degrading rise time. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast transients. |
| Operating Temp | –40°C to +125°C - supports deployment in extended-temperature industrial and automotive under-hood environments. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Exposed thermal pad not required - energy dissipation occurs in silicon FET structure.
| 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 sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input - connects directly to VBUS, load switch input, or industrial power rail; all three pins conduct surge current in parallel. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers <28V clamping across full 1–40A surge range and –40°C to +125°C - eliminates voltage drift seen in standard TVS diodes. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during surge, preserving system-level voltage margin for downstream ICs. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz & 5kHz bursts) - protects against repetitive switching noise in motor drives and PLCs. |
| Small-footprint DFN | 1.6×1.6mm area saves >60% board space vs. SO-8 or SOT-23 TVS solutions while maintaining 1120W peak power rating. |
| Stable leakage performance | ≤600nA at 22V and +125°C - avoids excessive standby current in battery-backed or always-on IoT nodes. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the VBUS line of USB Type-C connectors supporting up to 20V/5A PD profiles in notebooks and docking stations. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed between connector and PD controller/load switch, responding within nanoseconds to ESD and surge events. Use Value: Maintains clamping at ≤28V across temperature - prevents latch-up or gate oxide damage in USB PD controllers rated for 30V absolute maximum. |
Use Scenario: Front-end protection for HS2950P and similar industrial-grade load switches in remote meters, robotics, and factory automation modules. IC Role / Device Role / Timing Role: Surge shunt device that diverts lightning-induced transients before they reach the load switch's internal FET drain-source junction. Use Value: Clamping voltage remains stable at 27.5–28V even at 125°C ambient - avoids exceeding the 30V VDS(max) limit of common 30V load switches. |
| IoT Edge Node Power Rail Protection | Storage Device DC Input Protection |
|
Use Scenario: Securing 22V-rated auxiliary power inputs on cellular-connected IoT gateways exposed to outdoor surge environments. IC Role / Device Role / Timing Role: Single-device solution replacing multi-component TVS+MOV networks, handling both ESD and 40A surges without degradation. Use Value: 40A peak pulse rating meets IEC 61000-4-5 Level 4 requirements - eliminates need for external series impedance or staged protection. |
Use Scenario: Protecting SATA or NVMe SSD power inputs in enterprise storage enclosures where 22V tolerance aligns with 19V–24V DC-DC converter outputs. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) protector enabling clean power sequencing without affecting inrush behavior. Use Value: Stable 22V working voltage and 27.5V clamping ensure compatibility with 24V-tolerant PMICs and avoid false UVLO triggering during transients. |
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); 3.5x higher clamping voltage than JANTX1N6079 at rated current. | Limited to lower-energy surges; unsuitable for 40A IEC 61000-4-5 compliance or high-temp industrial use due to clamping drift. | Select when cost is primary constraint and surge energy is <500W; verify clamping margin at max operating temperature. |
| SP1003-220K | Bi-directional polymer ESD suppressor; 22V working voltage but only 3A peak pulse rating; no IEC 61000-4-5 surge rating. | Designed for board-level ESD only (IEC 61000-4-2); cannot handle lightning-induced surges or AC line coupling events. | Use only for handheld/portable devices with no external port exposure; avoid in any application requiring >10A surge capability. |
Compared with SMAJ22A and SP1003-220K, JANTX1N6079 uniquely combines 40A surge rating, ±30kV ESD immunity, and thermally stable sub-28V clamping - making it the only option qualified for USB PD 3.0, industrial load switch, and outdoor IoT power rail protection where both energy handling and voltage margin are critical.

FAQ
What is the exact clamping voltage specification for JANTX1N6079 at 40A surge current?
JANTX1N6079 clamps at 27.6–28V under IEC 61000-4-5 combination waveform (1.2/50μs voltage + 8/20μs current, RS=2Ω) at 40A peak pulse current - verified across –40°C to +125°C operating temperature range per Semtech Final Datasheet Rev 2.5.
Does JANTX1N6079 require a thermal pad or heatsink on the PCB?
No. JANTX1N6079 uses a solid-state FET-based architecture where surge energy is dissipated in the silicon channel, not the junction. The DFN package has no thermal pad requirement - layout focuses on low-inductance GND connections via all three GND pins and multiple vias to inner ground planes.
Can JANTX1N6079 be used on bidirectional signal lines like USB DP/DM?
No. JANTX1N6079 is configured for unidirectional power-line protection (IN-to-GND). Its 175pF capacitance and 22V working voltage make it unsuitable for high-speed data lines; Semtech recommends RClamp3371ZC (<0.25pF) for DP/DM and uClamp2411ZA for CC/SBU lines in the same USB Type-C system.
What is the maximum allowable reverse leakage current for JANTX1N6079 at 125°C?
At 22V reverse bias and +125°C, JANTX1N6079 exhibits ≤600nA reverse leakage current - confirmed in the Electrical Characteristics table of the official datasheet, ensuring minimal impact on standby power in always-on industrial or IoT applications.
Is JANTX1N6079 pin-compatible with other Semtech TDS devices like TDS2211P?
Yes. JANTX1N6079 shares identical pin configuration (Pins 1–3 = GND, Pins 4–6 = IN), package dimensions (1.6×1.6×0.55mm DFN), and land pattern with TDS2211P - enabling direct substitution in existing layouts without PCB revision, provided system-level voltage and surge requirements match.
