Product details
Overview
JANTXV1N6476US 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 40A, 20mΩ dynamic resistance, and DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD input protection.
For engineers reviewing the JANTXV1N6476US datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC response, 22V working voltage compliance, and compact DFN layout suitability for space-constrained USB PD and industrial load switch interfaces.
Technical Context
The JANTXV1N6476US implements 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.
It operates across –40°C to +125°C with stable 27.5–28V clamping at 24A and 40A (1.2/50μs voltage + 8/20μs current combination waveform, RS = 2Ω), and maintains <600nA reverse leakage at 22V. Its 175pF junction capacitance at 22V/1MHz supports moderate-speed bus protection without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and ensures reliable standoff during normal operation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below typical 30V damage thresholds of USB PD controllers and load switches. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds standard ESD immunity requirements for handheld and portable electronics. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage rise under increasing surge current. |
| Junction Capacitance | 175pF at 22V/1MHz - suitable for DC power rails and low-to-moderate-speed data lines (e.g., CC/SBU, VBUS). |
| Package | DFN 1.6×1.6×0.55mm, 6-lead - enables ultra-compact placement adjacent to USB Type-C connectors with minimal PCB area. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - all three must be connected to maximize surge current path integrity and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input - tied together to the VBUS or power rail; simultaneous connection ensures full 40A rating and balanced current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A surge range - eliminates design margin inflation needed with traditional TVS devices. |
| FET-based shunt topology | Surge energy dissipated via low-RDS(on) FET instead of PN-junction - enables stable performance up to +125°C ambient. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - reduces voltage overshoot during fast-rising transients like ESD. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports robust protection in industrial and metering applications exposed to lightning-induced surges. |
| Compact DFN footprint | 1.6×1.6mm area - saves >60% board space vs. SO-8 or SOT-23 alternatives while maintaining 6-terminal current-handling capability. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB Type-C ports supporting up to 20V/5A PD profiles against ESD, lightning surges, and connector hot-plug transients. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the connector, clamping overvoltage before it reaches the PD controller or e-fuse IC. Use Value: Maintains 27.5–28V clamping across –40°C to +125°C and 24–40A, preventing false trips or latch-up in wide-temperature industrial USB hosts. |
Use Scenario: Safeguarding input terminals of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes subjected to field-installed wiring surges. IC Role / Device Role / Timing Role: Primary front-end EOS protector that limits voltage seen by the load switch's internal MOSFET gate oxide and drain-source junction. Use Value: Prevents permanent damage to load switch ICs by holding clamping voltage well below their absolute maximum VDS ratings (typically 30–36V). |
| Storage Device Power Rail Protection | Notebook/Tablet VBUS Line Protection |
|
Use Scenario: Securing 22V-rated power inputs on NVMe SSD modules, SATA power adapters, and external storage enclosures against system-level ESD and conducted surges. IC Role / Device Role / Timing Role: Standalone transient suppressor on the main power rail, operating independently of downstream DC-DC regulation. Use Value: Delivers 40A surge handling in a 1.6×1.6mm footprint - enabling protection without compromising M.2 or U.2 form factor constraints. |
Use Scenario: Protecting VBUS routing in thin-client notebooks and detachable tablets where USB-C serves dual role as charging port and peripheral interface. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) suppressor minimizing standby power loss and avoiding signal coupling into adjacent high-speed traces. Use Value: Enables compliance with IEC 61000-4-2/4-4/4-5 while meeting strict thermal and space budgets in fanless mobile designs. |
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 +125°C), identical electrical specs and pinout - differs only in screening level and traceability. | Targeted at non-military industrial and consumer applications; lacks MIL-PRF-19500 qualification. | Select when full JANTXV screening is not required and cost-sensitive volume production is prioritized. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but lower 20A IPP rating and higher 33V clamping at 20A - uses silicon avalanche diode architecture, not FET-based clamping. | Better suited for CC/SBU lines in USB-C; not rated for sustained 40A surges on VBUS. | Choose only for auxiliary signal lines where lower capacitance (<0.5pF) and smaller size are critical - not a direct replacement for JANTXV1N6476US on power rails. |
Compared with TDS2211P.C and uClamp2411ZA, JANTXV1N6476US delivers military-grade reliability, guaranteed 40A surge handling, and flat clamping essential for protecting sensitive 22V power rails - making it the sole option qualified for high-reliability USB PD and industrial load switch deployments.

FAQ
What is the maximum operating temperature range for JANTXV1N6476US?
JANTXV1N6476US is rated for continuous operation from –40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range, with no degradation in 27.5–28V performance at 40A - verified per IEC 61000-4-5 testing and documented in Semtech's Rev 2.5 datasheet.
Does JANTXV1N6476US require external bias or control signals to operate?
No, JANTXV1N6476US is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET - no external power, enable pins, or configuration are needed. The JANTXV1N6476US activates automatically when transient voltage exceeds its breakdown threshold, making it ideal for always-on protection schemes.
How does JANTXV1N6476US differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), JANTXV1N6476US uses a FET-based shunt that lowers RDS(on) under surge, resulting in near-constant 27.5–28V clamping from 24A to 40A - a key advantage confirmed in Figure 3 of the JANTXV1N6476US datasheet.
Can JANTXV1N6476US be used on high-speed data lines like USB SuperSpeed or PCIe?
No - JANTXV1N6476US has 175pF junction capacitance at 22V, which is too high for differential high-speed lanes (e.g., USB 3.x, PCIe Gen3+). It is intended exclusively for DC power rails and low-speed control lines (e.g., VBUS, CC, SBU). For SuperSpeed protection, Semtech recommends RClamp3371ZC (0.25pF) alongside JANTXV1N6476US in hybrid protection schemes.
Is JANTXV1N6476US pin-compatible with other Semtech TDS devices?
JANTXV1N6476US shares the same DFN 1.6×1.6×0.55mm 6-lead package and 3-GND / 3-IN pin configuration with TDS2211P.C and TDS2411P, but voltage ratings differ: JANTXV1N6476US and TDS2211P.C are 22V-rated, while TDS2411P is 24V-rated. Direct substitution requires verification of working voltage and clamping alignment with system requirements.
