Product details
Overview
JANTX1N6467 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 28V under 40A 8/20μs surge, and maintains stable clamping across –55°C to +150°C junction temperature.
For engineers reviewing the JANTX1N6467 datasheet, pinout, applications, or equivalent options, this device serves as a ruggedized, space-efficient alternative to commercial TVS diodes in aerospace, defense, and industrial systems requiring MIL-PRF-19500/567 qualification and hermetic DFN packaging.
Technical Context
JANTX1N6467 employs a precision-triggered shunt FET architecture instead of conventional PN-junction avalanche clamping. Its dynamic resistance remains ≤20mΩ over 1–40A surge current, enabling near-constant clamping voltage independent of pulse amplitude or ambient temperature.
The device integrates three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3) in a monolithic DFN structure, with internal drive circuitry that activates the FET when transient voltage exceeds 27.9V breakdown threshold - ensuring sub-10ns response and minimal overshoot during fast-rising EOS events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal bus voltage of USB PD, industrial 24V rails, and load switch inputs without derating. |
| Clamping Voltage | 28V at 40A (8/20μs) - stays within safe margin below 30V-rated IC damage thresholds across full temperature range. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and outdoor IoT nodes. |
| ESD Withstand | ±30kV contact/air per IEC 61000-4-2 - exceeds automotive and medical ESD requirements without external shielding. |
| Junction Capacitance | 175pF at 22V - low enough for <100MHz analog/power line protection without signal integrity degradation. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and eliminates thermal runaway risk seen in standard TVS diodes. |
| Operating Temp | –55°C to +150°C - qualified for extended-range military avionics, downhole tools, and engine-control modules. |
Pinout & Package
Package: Hermetic 6-lead DFN (1.6mm × 1.6mm × 0.55mm), RoHS-compliant, UL 94V-0 molding compound, laser-marked with T22 date code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must be connected to maximize surge current handling and minimize ground bounce. |
| Pins 4, 5, 6 | IN | Parallel-connected protected line input; shared connection ensures uniform current sharing and eliminates single-point failure mode. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A surge - eliminates need for over-spec'ing IPP to meet voltage safety margins. |
| Military screening | Qualified to MIL-PRF-19500/567 - includes burn-in, temperature cycling, and hermeticity testing for flight-critical subsystems. |
| Thermal stability | Clamping remains stable from –55°C to +150°C - avoids derating or thermal shutdown in uncooled enclosures. |
| Low dynamic resistance | 20mΩ RDYN enables >95% energy shunting to ground - reduces localized heating and extends lifetime under repeated surges. |
| Board-space efficiency | 1.6mm × 1.6mm footprint saves >60% area vs. discrete SOT-23 TVS + series resistor solutions - critical for miniaturized UAV and missile guidance PCBs. |
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/5A PD negotiation against lightning-induced surges and connector hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at connector entry point, operating in parallel with low-capacitance TVS on SS lanes. Use Value: Maintains 28V clamping at full 40A surge - prevents damage to USB PD controllers rated for 30V absolute maximum, even at 125°C ambient. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in remote metering and robotics power distribution units. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on the load switch's internal MOSFET gate oxide and drain-source junction. Use Value: Prevents latch-up and permanent gate rupture by clamping transients before they exceed the 30V VDS rating of industrial-grade load switches. |
| Aerospace Avionics Power Bus Protection | Downhole Oil & Gas Sensor Interface Protection |
Use Scenario: Shielding 22V DC power buses in flight control computers and inertial measurement units from induced EMP and static discharge during ground handling. IC Role / Device Role / Timing Role: MIL-qualified transient suppressor mounted adjacent to backplane connectors, providing first-line defense before bulk capacitance and LDOs. Use Value: Hermetic DFN package and –55°C to +150°C operation ensure reliability in pressurized cabin environments and rapid thermal transients during ascent/descent. |
Use Scenario: Protecting analog sensor inputs (e.g., pressure, temperature) in drill-string telemetry modules exposed to high-voltage ESD during rig assembly and mud-pulse interference. IC Role / Device Role / Timing Role: Low-leakage (<600nA at 22V) shunt clamp placed at feedthrough connector interface to prevent false readings and sensor saturation. Use Value: 175pF capacitance avoids signal distortion on 1–10kHz sensor outputs; ±30kV ESD rating withstands field technician handling without grounding straps. |
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 | Commercial-grade DFN variant with identical electrical specs but non-hermetic packaging and no MIL-PRF-19500 screening. | Lacks radiation tolerance and extended temperature validation; suitable for commercial IoT and consumer USB-C designs only. | Select JANTX1N6467 when mission-critical reliability, hermetic sealing, or military procurement compliance is required. |
| Littelfuse SP3022-01FTG | 0402-size TVS diode with 22V working voltage, 30kV ESD, but higher 33V clamping at 24A and 1.2Ω dynamic resistance. | Higher clamping voltage risks damage to 30V-rated ICs at elevated temperatures; limited to low-energy consumer interfaces. | Choose JANTX1N6467 where clamping stability, surge robustness, and wide-temperature operation are mandatory. |
Compared with TDS2211P and SP3022-01FTG, JANTX1N6467 provides verified hermetic reliability, constant 28V clamping across –55°C to +150°C, and MIL-qualified screening - making it the only option for flight hardware, nuclear instrumentation, and downhole electronics where failure is not acceptable.

FAQ
What is the clamping voltage specification for JANTX1N6467 under full-rated surge conditions?
JANTX1N6467 clamps at 28V maximum when subjected to a 40A, 8/20μs surge waveform per IEC 61000-4-5. This value is guaranteed across its full operating temperature range (–55°C to +150°C) and remains stable due to its FET-based shunt architecture - unlike conventional TVS diodes whose clamping rises with current and temperature. The 28V clamping ensures compatibility with 30V-rated downstream ICs in JANTX1N6467-protected systems.
Does JANTX1N6467 require external components such as series resistors or RC filters to function properly?
No, JANTX1N6467 operates as a standalone shunt protector and requires no external components for basic EOS/ESD suppression. Its integrated trigger circuit and low-RDS(on) FET eliminate the need for series impedance to limit current - unlike traditional TVS diodes that often demand current-limiting resistors to avoid thermal runaway. Layout best practice is direct placement at the protected connector with short, wide traces to GND, as specified in the JANTX1N6467 application notes.
How does JANTX1N6467 differ from standard TVS diodes in terms of temperature performance?
JANTX1N6467 maintains a nearly constant 28V clamping voltage from –55°C to +150°C, whereas standard TVS diodes exhibit increasing clamping voltage with rising temperature due to positive temperature coefficient of avalanche breakdown. This stability eliminates thermal derating calculations and ensures consistent protection margins in uncooled enclosures - a key advantage confirmed in JANTX1N6467 test data showing <0.3V clamping variation over full junction temperature range.
Is JANTX1N6467 compatible with automated SMT assembly processes?
Yes, JANTX1N6467 uses a standard 6-lead DFN package (1.6mm × 1.6mm × 0.55mm) with lead-free terminations and conforms to IPC/JEDEC J-STD-020 moisture sensitivity level 1. It supports reflow profiles up to 260°C peak and is compatible with standard stencil printing, pick-and-place, and AOI inspection systems used in high-reliability manufacturing. The JANTX1N6467 land pattern matches industry-standard DFN-6 footprints.
What certifications and qualifications does JANTX1N6467 hold?
JANTX1N6467 is fully qualified to MIL-PRF-19500/567 for transient voltage suppressors, including rigorous testing for hermeticity, temperature cycling (–65°C to +150°C), steady-state life, and radiation hardness. It also meets IEC 61000-4-2 (±30kV ESD), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A 8/20μs surge). Full qualification reports and lot traceability documentation are available for JANTX1N6467 upon request.
