Product details
Overview
JANTX1N6468US from Microsemi (now Microchip) is a military-grade transient voltage suppression diode designed for high-reliability EOS/ESD protection of 22V DC power and signal lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 27.5–28V under 40A 8/20μs surges, and maintains stable clamping across –55°C to +150°C junction temperature. Used in avionics power bus protection where MIL-PRF-19500/567 qualification is required.
For engineers reviewing the JANTX1N6468US datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, DFN-6 package layout guidance, functional role in load switch and USB Type-C PD input protection, and qualified alternatives meeting MIL-STD-883 Class B screening.
Technical Context
JANTX1N6468US implements a transient diverting architecture using a surge-rated FET as the primary shunt element, activated by a precision trigger circuit - not a conventional PN-junction TVS. This enables near-constant clamping voltage (27.5–28V) across 24–40A peak pulse current and over full –55°C to +150°C operating range.
It features 20mΩ dynamic resistance (measured 1–40A, 8/20μs), 175pF junction capacitance at 22V/1MHz, and <600nA reverse leakage at VRWM = 22V. The device protects one unidirectional line with 22V working voltage and handles 1120W peak pulse power per IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - matches nominal USB PD 20V bus and industrial 24V rail systems without derating |
| Clamping Voltage | 27.5–28 V at 40A 8/20μs - stays below 30V damage threshold of common load switches and PD controllers |
| Peak Pulse Current | 40 A (8/20μs) - satisfies IEC 61000-4-5 Level 4 (±1kV, RS=42Ω) and lightning surge requirements |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards |
| Junction Capacitance | 175 pF at 22V/1MHz - low enough for 22V power-line protection without signal integrity impact |
| Dynamic Resistance | 20 mΩ - ensures minimal IR drop during surge conduction, preserving clamping stability |
| Operating Temp | –55°C to +150°C - supports extended-range operation in avionics, downhole, and engine bay environments |
Pinout & Package
Package: DFN-6 (1.6 mm × 1.6 mm × 0.55 mm), RoHS-compliant, UL 94V-0 molding compound, lead-free finish. Thermal pad not required - energy dissipated in silicon FET structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path - all three must be connected to maximize surge current handling and minimize parasitic inductance |
| Pins 4, 5, 6 | IN | Protected line input - tied together to form single high-current path to 22V bus or load switch VIN; no polarity sensitivity |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS with active shunt switching - eliminates linear VC = VBR + IPP×RDYN rise, enabling flat clamping |
| Temperature-stable clamping | Clamping voltage drift <0.1V from –55°C to +150°C - eliminates thermal derating calculations in high-temp designs |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated surge events without degradation in mission-critical systems |
| MIL-PRF-19500/567 qualified | Screened to JANTX level with burn-in, temperature cycling, and hermeticity testing - meets aerospace reliability requirements |
| Low dynamic resistance | 20mΩ enables <1V IR drop at 40A - preserves voltage margin between clamping and protected IC absolute maximum ratings |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch VIN Protection |
|---|---|
Use Scenario: Protecting USB-C receptacle VBUS lines exposed to ESD and lightning-induced surges in portable test equipment and docking stations. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at connector, clamping transients before they reach USB PD controller or e-fuse. Use Value: Maintains 27.5V clamping at 40A and 125°C - prevents overvoltage damage to CYPD3171/CYPD3177 PD controllers rated for 30V ABS MAX. |
Use Scenario: Securing input of HS2950P and similar industrial load switches in remote metering and robotics power rails. IC Role / Device Role / Timing Role: Front-end transient clamp on VIN pin, limiting voltage seen by internal FET gate oxide and OVP comparators. Use Value: 20mΩ RDYN ensures <0.8V IR drop at 40A - keeps clamped voltage well below 32V gate-source breakdown of integrated MOSFETs. |
| Avionics 28V DC Bus Protection | IoT Edge Node Power Input Protection |
Use Scenario: Hardening 22–28V aircraft auxiliary power distribution against induced transients from motor actuation and static discharge. IC Role / Device Role / Timing Role: MIL-qualified transient suppressor mounted at PDB entry point, compliant with DO-160 Section 22 Level 3. Use Value: JANTX screening and –55°C to +150°C operation ensure reliability across flight envelope; 40A rating covers worst-case coupled surge. |
Use Scenario: Protecting battery-powered IoT gateways with USB-C PD input from ESD during field deployment and hot-plug events. IC Role / Device Role / Timing Role: Low-capacitance (175pF), high-surge-capacity clamp on main power input, co-located with input fuse and filter. Use Value: ±30kV ESD rating eliminates need for secondary ESD stages; DFN-6 footprint saves space vs. SMA/SMB discrete TVS solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Commercial-grade, same DFN-6 package, identical electrical specs (22V VRWM, 28V VC, 40A IPP), but not MIL-screened | Lacks JANTX-level screening, burn-in, and hermeticity - suitable for commercial industrial and consumer USB-C PD designs | Select when cost, lead time, or commercial qualification suffices and aerospace/avionics certification is not required. |
| SM712-TP | Bidirectional TVS (±12V standoff), higher capacitance (1200pF), lower clamping (23V @ 10A), no FET-based architecture | Designed for RS-422/RS-485 data lines - unsuitable for 22V power rail protection due to bidirectional behavior and thermal derating | Only consider for low-voltage differential signaling; not a functional substitute for JANTX1N6468US in power-line applications. |
Compared with TDS2211P and SM712-TP, JANTX1N6468US uniquely combines military screening, flat-clamp FET architecture, and 22V power-line optimization - making it irreplaceable in avionics and high-reliability 28V system inputs where qualification and thermal stability are mandatory.

FAQ
What is the exact package type and footprint for JANTX1N6468US?
JANTX1N6468US uses a 6-pin DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed pad-less construction. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. Land pattern follows Semtech's recommended layout with multiple vias to inner ground planes - no thermal pad required. This matches the TDS2211P footprint exactly, enabling drop-in replacement in commercial designs.
Does JANTX1N6468US meet MIL-PRF-19500/567 requirements?
Yes, JANTX1N6468US is fully qualified to MIL-PRF-19500/567 Revision H, including JANTX-level screening: steady-state life test, temperature cycling, mechanical shock, vibration, and hermeticity per MIL-STD-883 Method 1014. It carries the "JANTX" prefix per MIL-PRF-19500, confirming compliance with military reliability and traceability mandates.
How does JANTX1N6468US differ from standard TVS diodes in clamping behavior?
Unlike standard PN-junction TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), JANTX1N6468US uses a triggered FET shunt that maintains 27.5–28V clamping from 24A to 40A and across –55°C to +150°C. Its 20mΩ RDYN ensures minimal IR drop, delivering predictable protection without thermal derating.
Can JANTX1N6468US protect bidirectional signal lines like USB DP/DM?
No - JANTX1N6468US is unidirectional and optimized for 22V power-line protection only. It connects GND to pins 1–3 and protected line to pins 4–6. For USB SuperSpeed (DP/DM) or CC/SBU lines, low-capacitance devices like RClamp3371ZC (<0.25pF) or uClamp2411ZA are required. JANTX1N6468US must not be used on data lines.
What is the maximum continuous power dissipation for JANTX1N6468US?
JANTX1N6468US is not rated for continuous power dissipation - it is a transient suppressor designed for short-duration surges (≤100ns to 20μs). Its absolute maximum rating specifies 1120W peak pulse power (tp = 8/20μs), but steady-state power handling is limited by junction temperature rise. Continuous DC power must remain below 100mW to avoid exceeding TJ(max) = +150°C under ambient conditions.
