Product details
Overview
JANTXV1N6461 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 20mΩ dynamic resistance - deployed in USB PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the JANTXV1N6461 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for 22V bus protection in high-reliability embedded and power delivery systems.
Technical Context
JANTXV1N6461 implements a surge-rated FET shunt architecture with precision trigger circuitry - unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A (8/20μs) and −40°C to +125°C due to decreasing RDS(on) under surge conditions. It operates as a voltage-controlled switch activated only during overvoltage events.
The device protects one unidirectional line with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and low 175pF junction capacitance at 22V/1MHz - enabling use on high-speed interfaces without signal integrity degradation when combined with low-capacitance TVS devices on data lanes.
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 + 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. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 ESD immunity for handheld and portable equipment interfaces. |
| Dynamic Resistance | 20mΩ - enables stable clamping by minimizing voltage rise (ΔV = I × R) across full surge current range. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for placement on VBus lines without degrading USB PD negotiation or power ramp timing. |
| Operating Temperature | −40°C to +125°C - supports deployment in automotive-grade industrial enclosures and thermally constrained IoT edge nodes. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish. Thermal pad not required - energy dissipated internally during transient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 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. |
| Pins 4, 5, 6 | IN | Protected line input - connects directly to VBus or power rail; all three pins are electrically parallel and must be tied together externally for rated 40A performance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A - eliminates design margin inflation needed with traditional TVS diodes whose VC rises linearly with IPP. |
| Temperature-stable protection | Clamping remains 27.5–28V across −40°C to +125°C - removes thermal derating calculations required for silicon-based TVS devices. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - minimizes IR drop during surge, preserving voltage headroom for downstream regulators and switches. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated exposure to lightning-induced surges in industrial fieldbus and metering applications. |
| DFN space efficiency | 1.6mm × 1.6mm footprint - reduces PCB area by >60% vs. SO-8 or SOT-23 TVS solutions rated for equivalent 40A surge capability. |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles supporting up to 100W PD negotiation and power sourcing. IC Role / Device Role / Timing Role: Primary high-energy EOS suppressor placed immediately after the connector, upstream of PD controller and load switch. Use Value: Maintains 27.5–28V clamping across full temperature range - prevents false overvoltage shutdowns and ensures reliable PD contract establishment under thermal stress. |
Use Scenario: Shielding HS2950P-type load switches and e-fuses from lightning-induced surges in remote meters, robotics, and factory automation nodes. IC Role / Device Role / Timing Role: Front-end transient shunt that limits voltage seen by the load switch's internal FET drain-source junction during 1.2/50μs surges. Use Value: Keeps clamped voltage below 30V - avoids gate oxide damage and latch-up in 30V-rated load switches while sustaining 40A surge without degradation. |
| IoT Edge Node Power Rails | Storage Device VBus Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors and wireless gateways exposed to ESD during field servicing or cable hot-plug events. IC Role / Device Role / Timing Role: Standalone EOS protector on main power input, co-located with input capacitor and upstream of DC-DC converters. Use Value: Delivers ±30kV ESD immunity without adding series impedance - preserves startup timing and avoids brownout during fast-rising ESD transients. |
Use Scenario: Safeguarding SATA or NVMe storage module VBus inputs against surges induced by hot-swap connectors or shared backplane power domains. IC Role / Device Role / Timing Role: High-current transient clamp on 22V supply rail feeding SSD power management ICs and flash controllers. Use Value: Limits voltage excursion to ≤28V during 40A surges - prevents premature reset or data corruption in storage firmware during transient events. |
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 +85°C), identical electrical specs and DFN-6 package - differs only in temperature rating and screening level. | Approved for non-military industrial and consumer USB-C designs; lacks MIL-PRF-19500 qualification. | Select when full JANTXV screening is unnecessary and cost-sensitive volume production is prioritized. |
| SMAJ22A | Standard unidirectional TVS diode, 22V VRWM, 35.5V VC @ 12.3A - higher clamping, fixed RDYN (~2.9Ω), no temperature stability. | Requires larger derating margin for 40A surges; clamping rises to ~42V at 125°C - unsuitable for tight 24V system margins. | Use only where lower cost and legacy compatibility outweigh clamping stability and surge headroom requirements. |
Compared with TDS2211P.C and SMAJ22A, JANTXV1N6461 provides military-grade temperature range (−55°C to +125°C), guaranteed 40A surge handling, and flat clamping - making it the sole option for aerospace, defense, and high-reliability industrial deployments requiring validated performance across extreme thermal and surge stress.

FAQ
What is the primary protection function of JANTXV1N6461?
JANTXV1N6461 functions as a transient diverting suppressor that activates a precision-triggered shunt FET during EOS events - clamping voltage to 27.5–28V while diverting up to 40A (8/20μs) to ground. Unlike TVS diodes, JANTXV1N6461 maintains near-constant clamping across current and temperature, making it ideal for protecting 22V power rails in USB PD and industrial systems.
Does JANTXV1N6461 require a thermal pad on the PCB?
No, JANTXV1N6461 does not require an exposed thermal pad. Its DFN-6 package dissipates surge energy internally via the shunt FET structure, and the datasheet explicitly states "no thermal pad is needed." Layout best practice focuses instead on low-inductance grounding: all three GND pins (1–3) must connect to a solid ground plane using multiple vias, and all three IN pins (4–6) must be tied together with a short, wide trace.
How does JANTXV1N6461 differ from standard TVS diodes like SMAJ22A?
JANTXV1N6461 uses a triggered FET shunt architecture, delivering 27.5–28V clamping at 40A with 20mΩ dynamic resistance - versus SMAJ22A's 35.5V clamping at 12.3A and rising VC with temperature. JANTXV1N6461 also achieves ±30kV ESD immunity and operates from −55°C to +125°C, whereas SMAJ22A is limited to −65°C to +150°C but lacks guaranteed flat clamping or military screening.
Can JANTXV1N6461 protect high-speed data lines such as USB SuperSpeed?
No - JANTXV1N6461 is intended for VBus or power rail protection only, with 175pF junction capacitance. For USB SuperSpeed (TX/RX), low-capacitance TVS devices like RClamp3371ZC (<0.25pF) are required. JANTXV1N6461 complements those devices in full USB Type-C protection schemes by handling high-energy surges on the power lane while leaving data lanes unaffected.
What is the meaning of "JANTXV" prefix in JANTXV1N6461?
The "JANTXV" prefix indicates compliance with MIL-PRF-19500/500, denoting a space- and military-grade version with enhanced screening, extended temperature range (−55°C to +125°C), and guaranteed reliability for high-consequence applications. JANTXV1N6461 shares the same die and electrical characteristics as TDS2211P.C but undergoes additional burn-in, temperature cycling, and lot acceptance testing per military specification.
