Product details
Overview
JANTXV1N6467US 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 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTXV1N6467US datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC vs. IPP behavior, DFN-6 package layout constraints, and compatibility with 22V bus systems requiring robust surge immunity per IEC 61000-4-5.
Technical Context
The JANTXV1N6467US implements a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and drives the shunt FET into low-RDS(on) conduction. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A peak pulse current due to decreasing FET on-resistance under surge conditions.
It operates over –40°C to +125°C, maintains stable 27.5–28V clamping up to 125°C, and delivers 1120W peak pulse power (8/20μs). Its 175pF capacitance at 22V and 1MHz supports moderate-speed data/power line protection without signal integrity compromise in USB PD and industrial bus applications.
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 waveform) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| Dynamic Resistance | 20mΩ - enables flat clamping response; VC rises only ~0.8V from 24A to 40A, unlike TVS diodes with linear VC = VBR + IPP×RDYN. |
| Junction Capacitance | 175pF at 22V, 1MHz - suitable for USB PD VBUS and load switch inputs where <500pF is acceptable; not for high-speed data lanes. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity for handheld and industrial interface ports. |
| Operating Temp | –40°C to +125°C - supports operation in automotive under-hood, industrial control, and outdoor IoT environments. |
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 pins must be connected to minimize inductance and maximize 40A capability. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS or load switch VIN); parallel connection of all three pins ensures uniform current sharing and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS with active shunt FET, enabling near-constant clamping voltage independent of surge magnitude or temperature. |
| Low dynamic resistance | 20mΩ ensures minimal voltage rise under high-current transients - critical for protecting 24V-tolerant ICs with tight overvoltage margins. |
| Stable clamping over temperature | VC remains 27.5–28V from –40°C to +125°C - eliminates derating required for conventional TVS diodes whose VC increases with ambient heat. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) supports repeated lightning-induced surges in industrial equipment and remote metering. |
| Compact DFN-6 footprint | 1.6mm × 1.6mm area saves >50% board space vs. SOT-23 or SOIC TVS solutions while maintaining full 40A performance. |
Applications

Use Value: ±30kV ESD immunity and stable clamping ensure system-level IEC 61000-4-2 Level 4 compliance without additional filtering or layout complexity. |
Use Scenario: Protecting 22V supply inputs of NVMe SSD enclosures or enterprise storage backplanes against power rail surges during hot-swap or AC line disturbances. IC Role / Device Role / Timing Role: High-power transient clamp on primary 22V rail, placed adjacent to connector to minimize trace inductance before energy reaches PMIC or controller. Use Value: 1120W peak power rating and 175pF capacitance allow robust surge suppression without compromising power integrity or triggering false overvoltage faults in storage controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P | Same silicon die and DFN-6 package; JANTXV1N6467US is the MIL-PRF-19500/630 qualified variant with extended screening and traceability. | Qualified for military/aerospace use per JANTXV level; identical electrical specs but enhanced reliability testing and lot traceability. | Select JANTXV1N6467US when DO-254/DO-178, MIL-HDBK-217F, or extended temperature life testing is required. |
| Littelfuse SP3022-01WTG | TVS diode (not FET-based); 24V VRWM, 35.5V VC @ 20A, higher clamping, no flat VC vs. IPP behavior. | Lacks constant-clamp advantage; requires larger derating margin for high-temp or high-IPP designs. | Choose only if cost sensitivity outweighs clamping stability needs and 35.5V VC is acceptable for protected ICs. |
Compared with TDS2211P and SP3022-01WTG, JANTXV1N6467US delivers identical clamping performance with certified military-grade reliability, while SP3022-01WTG trades flat VC response for lower unit cost but imposes stricter voltage margin design constraints.

FAQ
What is the primary protection function of JANTXV1N6467US?
JANTXV1N6467US functions as a transient diverting suppressor that uses a surge-rated FET and precision trigger circuit to shunt high-energy EOS events (e.g., ESD, lightning surges) to ground. It clamps the protected line at 27.5–28V during 40A transients, ensuring downstream 24V-rated ICs remain within safe operating limits. Its FET-based architecture distinguishes JANTXV1N6467US from passive TVS diodes by delivering flat clamping voltage across current and temperature ranges.
How does JANTXV1N6467US differ from standard TVS diodes in clamping behavior?
JANTXV1N6467US maintains a nearly constant clamping voltage of 27.5–28V from 24A to 40A and across –40°C to +125°C, whereas standard TVS diodes exhibit linear VC = VBR + IPP×RDYN behavior - causing clamping to rise significantly with current or temperature. This difference stems from JANTXV1N6467US's active FET shunt, whose RDS(on) decreases under surge, versus the fixed RDYN of PN-junction TVS devices.
What is the correct PCB layout practice for JANTXV1N6467US to achieve full 40A surge rating?
To achieve the full 40A peak pulse current rating, all three GND pins (1, 2, 3) and all three IN pins (4, 5, 6) of JANTXV1N6467US must be individually connected with short, wide traces to solid ground and input planes. Use multiple vias under GND pads to minimize inductance, place JANTXV1N6467US within 5mm of the protected connector, and avoid stubs or splits in the IN/GND paths - deviations reduce effective surge current handling and increase clamping voltage.
Is JANTXV1N6467US suitable for protecting high-speed data lines like USB SuperSpeed differential pairs?
No, JANTXV1N6467US is not suitable for USB SuperSpeed (TX/RX), DisplayPort, or other high-speed data lanes due to its 175pF junction capacitance, which would degrade signal integrity. It is designed exclusively for 22V power or low-to-moderate-speed I/O lines (e.g., VBUS, CC, SBU, load switch inputs). For data lines, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25pF) alongside JANTXV1N6467US in complete interface protection schemes.
What qualification standards apply to JANTXV1N6467US that distinguish it from commercial-grade TDS2211P?
JANTXV1N6467US is qualified to MIL-PRF-19500/630, including extended temperature cycling (–65°C to +150°C), hermeticity testing, radiation hardness assurance, and lot traceability per MIL-STD-9858A. While electrically identical to TDS2211P, JANTXV1N6467US undergoes additional screening for burn-in, parameter verification, and failure analysis - making it suitable for aerospace, defense, and high-reliability industrial applications where commercial parts lack certification.
