Product details
Overview
JANTXV1N6476 from Semtech is a transient diverting suppressor 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, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTXV1N6476 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternative comparisons for EOS-critical 22V bus protection designs.
Technical Context
JANTXV1N6476 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transients to ground. 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 up to 125°C, unlike conventional TVS diodes whose clamping rises with temperature and current. It supports unsymmetrical line surge testing per IEC 61000-4-5 (±1kV, 1.2/50μs, RS = 42Ω) and EFT immunity up to ±4kV (IEC 61000-4-4).
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 conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 22V-rated ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards without derating. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with medium-speed power/data lines (e.g., USB PD VBUS, load switch inputs), not high-speed data lanes. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| 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); all three pins are internally paralleled and must be tied together at PCB level for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A and −40°C to +125°C - eliminates thermal derating and simplifies worst-case margin analysis. |
| FET-based shunt topology | Replaces PN-junction TVS with low-RDS(on) MOSFET triggered by precision voltage reference - avoids junction heating and enables higher energy absorption. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - reduces voltage overshoot during sub-100ns ESD events and improves system-level robustness. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz bursts) - protects against repetitive switching noise in industrial motor drives and PLC I/O modules. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS line of USB-C ports supporting up to 20V/5A PD negotiation against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed immediately after the USB-C receptacle, before the PD controller and load switch. Use Value: Maintains 27.5–28V clamping at 125°C - prevents false overvoltage shutdown or latch-up in PD controllers rated for 24–28V absolute max. |
Use Scenario: Shielding enable-controlled load switches (e.g., HS2950P) in remote meters and robotics from 1kV/42Ω line surges during field deployment. IC Role / Device Role / Timing Role: Input-side transient clamp preventing gate oxide damage and drain-source breakdown in integrated e-fuse FETs. Use Value: Limits transient voltage to ≤28V - stays below typical 30V VDSS rating of industrial load switches, avoiding catastrophic failure. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
Use Scenario: Securing 22V auxiliary rails powering cellular modems, GNSS receivers, and sensor hubs in battery-backed outdoor IoT gateways. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on unregulated input rails exposed to harsh environments. Use Value: Delivers 40A surge capability in 1.6×1.6mm footprint - replaces larger multi-component TVS+MOV solutions while reducing board area by >60%. |
Use Scenario: Safeguarding 22V intermediate bus in NVMe SSD enclosures and enterprise HDD backplanes against hot-swap transients and backplane coupling. IC Role / Device Role / Timing Role: High-reliability clamping element on power entry point, coordinated with low-capacitance TVS on data lanes (e.g., RClamp3371ZC). Use Value: 175pF capacitance avoids signal integrity degradation on 22V bias rails - unlike high-capacitance polymer TVS or MOVs that induce ripple or instability. |
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, identical electrical specs, DFN-6 package, commercial-grade temp range (−40°C to +85°C) vs. JANTXV1N6476's extended −55°C to +150°C storage rating. | Approved for commercial/industrial use only; not qualified to MIL-PRF-19500 JANTXV screening levels (e.g., burn-in, lot acceptance tests). | Select when cost-sensitive and military qualification is unnecessary; verify thermal design margins at >85°C ambient. |
| SM712-TP | Bi-directional TVS array (12V/24V), 350W peak power, 15A IPP (8/20μs), 30V clamping at 15A - lacks constant-clamp behavior and exhibits >3V clamping rise from 5A to 15A. | Used in RS-485/RS-232 interfaces; requires derating above 70°C and cannot sustain 40A without significant voltage overshoot. | Choose only for lower-energy applications (<15A) where bidirectional protection and legacy TVS familiarity outweigh clamping stability needs. |
Compared with TDS2211P.C and SM712-TP, JANTXV1N6476 provides guaranteed military-grade reliability screening, stable 28V clamping across full temperature and current range, and 2.7× higher peak pulse current - making it the sole option for mission-critical 22V EOS protection where thermal margin and surge headroom are non-negotiable.

FAQ
What is the maximum continuous operating voltage for JANTXV1N6476?
JANTXV1N6476 has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC or RMS without significant leakage or conduction. This makes JANTXV1N6476 ideal for protecting 22V nominal power rails such as USB PD VBUS, industrial 24V systems with tolerance margins, and storage device intermediate buses.
How does JANTXV1N6476 achieve stable clamping voltage across temperature and current?
JANTXV1N6476 uses a surge-rated FET activated by a precision trigger circuit instead of a conventional PN-junction TVS. As surge current increases, the FET's RDS(on) decreases, maintaining clamping voltage near the trigger circuit's breakdown voltage. This architecture ensures JANTXV1N6476 clamps at 27.5–28V from −40°C to +125°C and across 24–40A, unlike standard TVS devices whose clamping rises linearly with both parameters.
Can JANTXV1N6476 be used on high-speed data lines like USB SuperSpeed or PCIe?
No - JANTXV1N6476 has 175pF junction capacitance at 22V, which would severely degrade signal integrity on high-speed differential pairs. It is intended exclusively for power or medium-speed control lines (e.g., VBUS, load switch enable, CC/SBU). For USB SS or PCIe lanes, low-capacitance TVS devices like RClamp3371ZC (<0.25pF) must be used alongside JANTXV1N6476 in a coordinated protection scheme.
What is the recommended PCB layout for optimal performance of JANTXV1N6476?
Place JANTXV1N6476 as close as possible to the protected connector or entry point. Connect all three IN pins (4,5,6) via a single short, wide trace to the protected line, and tie all three GND pins (1,2,3) directly to a solid ground plane using multiple vias. Avoid thermal pads or isolated copper - energy is dissipated in the silicon, not the package. This layout minimizes parasitic inductance and ensures JANTXV1N6476 delivers its full 40A rating.
Is JANTXV1N6476 pin-compatible with other Semtech TDS devices?
JANTXV1N6476 shares the same DFN-6 1.6×1.6mm package and pin configuration (Pins 1–3 = GND, Pins 4–6 = IN) with TDS2211P.C and TDS2411P, but is not a drop-in replacement due to its JANTXV qualification level, extended storage temperature range (−55°C to +150°C), and tighter screening. Electrical behavior is identical, but mechanical and reliability validation differs - always verify qualification documentation before substitution.
