Product details
Overview
JANTXV1N6466 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, and ultra-low 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the JANTXV1N6466 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, DFN-6 package layout constraints, 22V working voltage compliance, and shunt-FET-based protection architecture versus conventional TVS diodes.
Technical Context
The JANTXV1N6466 implements a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike standard TVS diodes, its clamping voltage remains nearly constant-27.5–28V-from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with stable breakdown voltage (25–27.9V), low leakage (<600nA at 22V), and 175pF junction capacitance at 22V/1MHz. Its functional architecture enables reliable protection of high-voltage USB PD buses and load switch inputs where thermal derating and clamping predictability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD systems |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements for connector-facing protection |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with 22V power rail protection; not suitable for high-speed data lines |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish. Pin 1 marked with laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current handling and minimize parasitic inductance |
| 4, 5, 6 | IN | Protected line input (e.g., USB PD VBus); parallel connection required to achieve full 40A rating and optimal clamping performance |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A surge range-enables predictable protection margin for 22V-system ICs |
| Temperature-stable clamping | Clamps at ~27.5–28V from –40°C to +125°C-eliminates thermal derating concerns common with TVS diodes |
| Shunt-FET protection core | Replaces PN-junction avalanche with low-RDS(on) MOSFET-dissipates energy in channel rather than junction, improving reliability |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs)-reduces voltage overshoot during sub-microsecond transients |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V USB PD VBus lines against lightning-induced surges and connector ESD events in notebooks, docking stations, and chargers.

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; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, no temperature stability | Higher clamping voltage increases risk of downstream IC damage at elevated temperatures or full surge current | Use only where cost is primary constraint and 35.5V clamping is acceptable for protected device's absolute max rating |
| TDS2211P | Same manufacturer, identical specs and package-JANTXV1N6466 is the MIL-PRF-19500/615 qualified version of TDS2211P | No functional difference; JANTXV1N6466 adds military screening (temperature cycling, burn-in, lot traceability) | Select JANTXV1N6466 for aerospace, defense, or high-reliability industrial programs requiring QML-38534 compliance |
Compared with SMAJ22A, JANTXV1N6466 delivers 8V lower clamping at full surge current and stable performance across –40°C to +125°C, while TDS2211P shares identical electrical behavior but lacks military qualification-making JANTXV1N6466 the sole choice for programs requiring MIL-STD-883 screening and traceability.

FAQ
What is the primary protection function of JANTXV1N6466?
JANTXV1N6466 functions as a transient diverting suppressor that uses a surge-rated FET and precision trigger circuit to clamp overvoltage events on 22V power or I/O lines. Unlike TVS diodes, it maintains a near-constant 27.5–28V clamping voltage across its full 40A surge rating and operating temperature range, making it ideal for protecting sensitive USB PD controllers and load switches.
How does JANTXV1N6466 differ from standard TVS diodes like SMAJ22A?
JANTXV1N6466 differs fundamentally: it employs a shunt-FET architecture instead of a PN-junction avalanche structure. This yields 20mΩ dynamic resistance, flat clamping (≤0.5V variation from 24A–40A), and temperature-independent performance-whereas SMAJ22A exhibits rising clamping voltage with both current and temperature, reaching 35.5V at 12.3A and degrading further at 125°C.
What are the PCB layout requirements for optimal performance of JANTXV1N6466?
For optimal JANTXV1N6466 performance, connect all three GND pins (1, 2, 3) and all three IN pins (4, 5, 6) in parallel using short, wide traces. Place the device within 5mm of the protected connector. Use multiple vias from GND pins to an internal ground plane to minimize inductance. Avoid thermal pads-energy is dissipated in the FET channel, not the die junction.
Is JANTXV1N6466 suitable for protecting high-speed data lines such as USB SuperSpeed or PCIe?
No, JANTXV1N6466 is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V is optimized for 22V power rail and VBus protection-not signal integrity. For USB SS, DP/DM, or other high-speed interfaces, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). JANTXV1N6466 is strictly intended for power and robust I/O line protection.
What qualification standards does JANTXV1N6466 meet beyond commercial-grade TDS2211P?
JANTXV1N6466 is manufactured to MIL-PRF-19500/615 and screened per MIL-STD-883, including temperature cycling, steady-state life test, and lot acceptance testing. It carries QML-38534 certification, providing full traceability, extended temperature validation (–65°C to +150°C storage), and enhanced reliability metrics-unavailable in the commercial TDS2211P variant.
