Product details
Overview
JANTX1N6468 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 performance from −55°C to +150°C. Used in avionics power bus protection and ruggedized industrial control I/O interfaces.
For engineers reviewing the JANTX1N6468 datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for MIL-PRF-19500/567-compliant designs requiring >1120W peak pulse power and <20mΩ dynamic resistance.
Technical Context
JANTX1N6468 implements a solid-state shunt architecture using a precision-triggered surge-rated FET, not a conventional PN-junction TVS. Its clamping voltage remains nearly constant (27.5–28V) across 24–40A peak pulse current due to sub-20mΩ dynamic resistance and active drive circuit activation above breakdown.
The device operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V at 1mA, and junction capacitance of 175pF at 22V/1MHz - enabling robust protection without signal integrity compromise in USB PD and industrial load-switch input circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 28V at 40A (8/20μs) - stays below 30V damage threshold of most 3.3V/5V logic and USB PD controllers. |
| Peak Pulse Power | 1120W - sustains IEC 61000-4-5 Level 4 (±1kV, RS=42Ω) surges on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 ESD immunity requirements for field-deployed equipment. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V - low enough for 100Mbps+ data lines when placed on power rails or low-speed I/O. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| 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 distribute 40A surge current across parallel bond wires and reduce thermal stress. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A - eliminates need for over-spec'ing IPP to meet voltage limits. |
| Temperature-stable protection | Clamping holds at 27.5–28V from −55°C to +125°C - removes thermal derating calculations in wide-temperature deployments. |
| Low dynamic resistance | 20mΩ enables <1V overshoot during 100A/μs dV/dt events - critical for protecting sensitive gate drivers and ADC references. |
| High-energy surge rating | Rated for 40A 8/20μs waveform - meets IEC 61000-4-5 Ed.3 Annex A for industrial port protection. |
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 power delivery against lightning-induced surges and hot-plug transients. IC Role / Device Role / Timing Role: Primary shunt suppressor placed between VBUS and chassis ground, activated within nanoseconds of overvoltage detection. Use Value: Maintains 28V clamping at full 40A surge - prevents latch-up or gate oxide rupture in USB PD controllers like TUSB73x or CYPD317x. | Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., MIC94300, TPS229xx) in programmable logic controllers and remote I/O modules. IC Role / Device Role / Timing Role: Front-end transient diverter that diverts surge energy before it reaches the switch's internal FET drain-source junction. Use Value: Limits voltage seen by load switch to ≤28V - avoids exceeding 30V absolute maximum rating and prevents catastrophic failure during 1kV ring-wave tests. |
| Avionics Power Bus Protection | IoT Edge Node Power Rail Protection |
Use Scenario: Hardening 28V DC distribution buses in airborne communication systems against induced transients per DO-160 Section 22 Level 3. IC Role / Device Role / Timing Role: MIL-PRF-19500/567-qualified shunt protector mounted directly at connector entry points on ARINC 429 or RS-485 interface cards. Use Value: Operates from −55°C to +150°C with no clamping drift - ensures compliance across full aircraft environmental envelope without recalibration. | Use Scenario: Securing 24V auxiliary power inputs on battery-backed smart sensors deployed in oilfield telemetry or factory automation gateways. IC Role / Device Role / Timing Role: First-line defense against ESD from human contact and inductive kickback from solenoid drivers sharing same supply rail. Use Value: Delivers ±30kV contact ESD immunity while adding only 175pF capacitance - preserves signal integrity on shared 24V bias rails powering analog front-ends. |
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 22V VRWM, identical DFN-6 package, 28V clamping at 40A, but commercial-grade (−40°C to +125°C) and non-military screened. | Approved for USB-C, IoT, and industrial equipment - not qualified to MIL-PRF-19500 or tested per MIL-STD-750 Method 2024. | Select when cost, lead time, or commercial qualification suffice and extended temperature range is not required. |
| Littelfuse SP3022-01WTG | 22V working voltage, ±30kV ESD, but uses silicon avalanche diode architecture - clamping rises to ~36V at 40A and degrades above 85°C. | Targeted at consumer USB ports and embedded displays - lacks the flat clamping and temperature stability needed for avionics or high-reliability industrial use. | Select only for cost-sensitive, non-mission-critical applications where 8V higher clamping is acceptable and ambient stays below 85°C. |
Compared with JANTX1N6468, TDS2211P offers identical electrical performance in a commercial-grade package, while SP3022-01WTG trades clamping stability and temperature resilience for lower unit cost - making JANTX1N6468 the sole choice for MIL-STD-810G, DO-160, or extended-temperature deployments demanding guaranteed 28V clamping across full life cycle.

FAQ
What is the maximum operating temperature range for JANTX1N6468?
JANTX1N6468 is rated for operation from −55°C to +150°C, meeting MIL-PRF-19500/567 screening requirements. This extended range ensures reliable clamping performance in avionics bays, engine-mounted controls, and outdoor industrial enclosures where ambient temperatures exceed commercial-grade limits. The JANTX1N6468 maintains its 28V clamping voltage across this entire span without derating.
Does JANTX1N6468 require external bias or control signals to function?
No, JANTX1N6468 is a passive, self-triggering device with no external control pins or bias requirements. It activates automatically when transient voltage exceeds its 25–27.9V breakdown threshold, turning on the internal shunt FET via an integrated precision trigger circuit. This makes JANTX1N6468 drop-in compatible with existing TVS layouts and eliminates need for additional support circuitry - simplifying design and reducing BOM count.
How does JANTX1N6468 differ from standard TVS diodes in clamping behavior?
JANTX1N6468 uses a surge-rated FET and active trigger circuit instead of a passive PN junction, resulting in near-constant 27.5–28V clamping from 24A to 40A - unlike standard TVS diodes whose clamping rises linearly with current (VC = VBR + IPP × RDYN). This eliminates voltage overshoot risk during high-energy surges and removes need to overspecify peak current rating just to meet clamping targets. JANTX1N6468 achieves this with 20mΩ dynamic resistance.
Can JANTX1N6468 be used on high-speed data lines such as USB SuperSpeed or PCIe?
JANTX1N6468 is not intended for placement directly on high-speed differential data lanes due to its 175pF junction capacitance, which would degrade signal integrity. It is optimized for power rails (VBUS, 24V aux), enable/control lines, and low-speed I/O. For USB SS, DP/DM, or PCIe lanes, use low-capacitance devices like RClamp3371ZC (<0.25pF). JANTX1N6468 complements those by protecting the shared power domain feeding those interfaces.
Is JANTX1N6468 compliant with RoHS and REACH regulations?
Yes, JANTX1N6468 is manufactured with Pb-free terminations and halogen-free molding compound, fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its DFN-6 package carries UL 94V-0 flammability rating and is supplied in tape-and-reel packaging per MIL-STD-1285. Traceability documentation, including material declarations and conflict minerals reporting, is available upon request for JANTX1N6468.
