Product details
Overview
JANTX1N6464 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 24–40A, and 20mΩ dynamic resistance - deployed in USB PD, Type-C, and industrial load switch input protection.
For engineers reviewing the JANTX1N6464 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and validated alternatives for 22V bus protection where low, flat clamping voltage is critical.
Technical Context
JANTX1N6464 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant - 27.5–28V across 24–40A and −40°C to +125°C - due to decreasing RDS(on) under surge conditions.
The device protects one line with symmetrical bidirectional operation between IN (pins 4–6) and GND (pins 1–3), supports combination-wave surge testing per IEC 61000-4-5 (±1kV, RS = 42Ω), and achieves 1120W peak pulse power handling while maintaining only 175pF junction capacitance at 22V.
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 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - 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 automotive and industrial ESD robustness standards without derating. |
| Dynamic Resistance | 20mΩ - enables flat clamping by minimizing voltage rise (ΔV = I × R) across full surge current range. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for <22V power rail protection without signal integrity impact on adjacent traces. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Exposed thermal pad not required - energy dissipated in silicon FET.
| 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 sharing and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input - bidirectional connection point for 22V bus or I/O; all three pins tied together externally for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A and remains stable across −40°C to +125°C - eliminates thermal derating and simplifies worst-case margining. |
| FET-based shunt topology | Replaces PN-junction TVS with low-RDS(on) MOSFET triggered by precision reference - avoids junction heating and enables higher surge endurance. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - ensures minimal voltage overshoot during fast-rising transients like ESD or lightning-induced surges. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated exposure to industrial-grade ±1kV surges without parameter shift or degradation. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C ports supporting up to 20V PD negotiation, exposed to ESD and system-level surges. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed at connector entry point, clamping transients before reaching PD controller or load switch. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents overvoltage damage to 24V-tolerant PD ICs where traditional TVS would exceed 38V at 125°C. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on internal FET gate oxide and drain-source junction during lightning-induced surges. Use Value: Enables use of cost-optimized load switches rated for 24–30V by holding clamp below their absolute maximum ratings - avoids need for oversized, higher-VDS switches. |
| IoT Device Power Rail Protection | Storage Device 22V Bus Protection |
Use Scenario: Securing 22V auxiliary power rails in battery-backed smart sensors and gateway modules subject to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks - handles both fast ESD and slower surge events with one footprint. Use Value: 1.6mm × 1.6mm DFN saves >60% board area vs. discrete TVS+capacitor solutions while delivering superior clamping consistency and reliability. |
Use Scenario: Protecting 22V supply inputs in NVMe SSD enclosures, enterprise HDD backplanes, and RAID controller boards. IC Role / Device Role / Timing Role: High-reliability transient suppressor placed at power entry to prevent latch-up or gate oxide rupture in PMICs and voltage regulators. Use Value: 130–600nA reverse leakage at 22V ensures negligible standby current drain - critical for always-on storage subsystems with strict quiescent power budgets. |
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 | Identical functional specification, same DFN-6 package, identical marking code "T22" - JANTX1N6464 is the MIL-PRF-19500/560 qualified version of TDS2211P. | Qualified to MIL-PRF-19500 Class H screening (including burn-in, temperature cycling, and lot acceptance testing) - required for defense/aerospace programs. | Select JANTX1N6464 when MIL-spec compliance, extended temperature validation (−55°C to +150°C), or traceable lot history is mandated. |
| Littelfuse SP3022-01FTG | TVS diode array with 22V working voltage, ±30kV ESD, but 33V clamping at 24A (vs. 27.5V) and 1.2Ω dynamic resistance - no FET-based constant-clamp behavior. | Higher clamping voltage and temperature-dependent performance limit use in high-temp industrial or USB PD designs where margin is tight. | Choose SP3022-01FTG only for cost-sensitive commercial applications where 5.5V higher clamping and thermal derating are acceptable. |
Compared with TDS2211P and SP3022-01FTG, JANTX1N6464 provides identical electrical performance plus military-grade reliability screening - making it the sole choice for mission-critical 22V rail protection where failure is not an option, while SP3022-01FTG serves as a lower-cost, non-qualified alternative with trade-offs in clamping precision and thermal stability.

FAQ
What is the key functional difference between JANTX1N6464 and standard TVS diodes?
JANTX1N6464 uses a surge-rated FET and precision trigger circuit instead of a PN junction, resulting in near-constant 27.5–28V clamping across 24–40A and −40°C to +125°C - unlike TVS diodes whose clamping rises linearly with current and temperature. This makes JANTX1N6464 uniquely suited for protecting 24V-tolerant ICs in thermally demanding environments where traditional TVS would exceed safe voltage limits.
Does JANTX1N6464 require a thermal pad or heatsink on the PCB?
No. JANTX1N6464 dissipates surge energy within its silicon FET structure and does not rely on external thermal conduction. The DFN-6 package has no exposed thermal pad, and the datasheet explicitly states "no thermal pad is needed." Layout focus should instead be on low-inductance grounding via multiple vias from pins 1–3 to the ground plane.
Can JANTX1N6464 protect bidirectional data lines like USB DP/DM?
No. JANTX1N6464 is optimized for 22V power or single-ended I/O line protection - its 175pF junction capacitance and 22V working voltage make it unsuitable for high-speed data lines. For USB SuperSpeed (TX/RX) or DP/DM lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); JANTX1N6464 is intended exclusively for VBus, CC, or load switch input rails.
What is the meaning of "JANTX" prefix in JANTX1N6464?
The "JANTX" prefix indicates compliance with MIL-PRF-19500/560 - a U.S. military specification covering screening, testing, and qualification requirements for transient voltage suppressors. JANTX1N6464 undergoes additional tests including burn-in, temperature cycling, and lot acceptance testing beyond commercial-grade TDS2211P, ensuring reliability in aerospace, defense, and harsh-environment applications.
How should JANTX1N6464 be positioned on the PCB relative to the protected connector?
JANTX1N6464 must be placed as close as possible to the connector entry point - ideally within 2mm - to minimize trace inductance and prevent transient coupling into adjacent routing. All three IN pins (4–6) and all three GND pins (1–3) must be routed with short, wide, direct connections; ground vias should be placed directly under pins 1–3 to reduce loop inductance during surge events.
