Product details
Overview
JANTXV1N6119AUS/TR from Microsemi (now Microchip) is a military-grade transient voltage suppression diode rated for 400W peak pulse power, 15.6V breakdown voltage, and 1.0μA maximum reverse leakage at 12.8V; used in avionics power rail protection against ESD and lightning-induced transients.
For engineers reviewing the JANTXV1N6119AUS/TR datasheet, JANTXV1N6119AUS/TR pinout, JANTXV1N6119AUS/TR application, or JANTXV1N6119AUS/TR equivalent, key selection criteria include MIL-PRF-19500/530 qualification, unidirectional polarity, DO-213AB package compatibility, and clamping voltage of 23.2V at 17.5A.
Technical Context
This device operates as a unidirectional TVS diode with avalanche breakdown mechanism, designed to clamp transient overvoltages within nanoseconds. It meets MIL-PRF-19500/530 Class H requirements for high-reliability space and defense systems.
Its 15.6V nominal breakdown voltage ensures stable triggering across temperature (-65°C to +175°C), while the 23.2V maximum clamping voltage at 17.5A IPP defines the protected circuit's worst-case overvoltage exposure during surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 15.6V min at 1mA; sets precise overvoltage trip threshold for rail protection |
| Clamping Voltage | 23.2V max at 17.5A IPP; limits peak voltage seen by downstream ICs |
| Peak Pulse Power | 400W at 10/1000μs waveform; sustains military-grade surge energy |
| Reverse Leakage | 1.0μA max at 12.8V; minimizes standby power loss in high-impedance circuits |
| Operating Temp | -65°C to +175°C; supports extended-range deployment in harsh environments |
| Qualification | MIL-PRF-19500/530 Class H; certified for spaceflight and airborne systems |
Pinout & Package
Package: DO-213AB (glass passivated, axial-leaded, hermetically sealed).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connects to protected line; conducts surge current to ground when voltage exceeds VBR |
| Anode | Reference node | Typically tied to system ground; completes clamping path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass package | Enables operation in vacuum and high-humidity aerospace environments without degradation |
| MIL-PRF-19500/530 Class H | Guarantees screening, testing, and traceability per military reliability standards |
| Low capacitance (≤100pF) | Preserves signal integrity on DC power rails without affecting control loop stability |
| Fast response time (<1.0ns) | Activates before sensitive components experience damaging overvoltage stress |
Applications
| Avionics Power Distribution | Satellite Bus Protection |
|---|---|
Use Scenario: 28V DC power bus in fighter aircraft flight control systems exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power rail upstream of DC-DC converters and FPGAs.

IC Role / Device Role / Timing Role: High-energy transient suppressor across bus inputs to protect sequencer logic and pyro drivers. Use Value: Operates reliably at +175°C ambient, enabling direct mounting near propulsion electronics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6118AUS/TR | 14.4V breakdown, 21.2V clamping at 17.5A; 350W rating | Better suited for 24V systems with tighter clamping margin | Select when lower VBR and reduced clamping voltage are required for 24V rail protection |
| JANTXV1N6120AUS/TR | 16.7V breakdown, 24.4V clamping at 17.5A; 400W rating | Optimized for 28V–32V systems requiring higher trip threshold | Choose for 28V avionics where margin above nominal rail must exceed 15.6V |
Compared with JANTXV1N6118AUS/TR and JANTXV1N6120AUS/TR, the JANTXV1N6119AUS/TR provides the optimal balance of trip threshold and clamping headroom for 28V military power systems, with identical packaging and screening for drop-in replacement in existing DO-213AB footprints.

FAQ
What is the breakdown voltage tolerance for JANTXV1N6119AUS/TR?
The JANTXV1N6119AUS/TR has a minimum breakdown voltage of 15.6V at 1mA test current, with no upper limit specified in the MIL-PRF-19500/530 specification; actual units measure between 15.6V and 16.7V. This tight lower bound ensures consistent overvoltage triggering across all JANTXV1N6119AUS/TR devices in high-reliability deployments.
Is JANTXV1N6119AUS/TR unidirectional or bidirectional?
JANTXV1N6119AUS/TR is a unidirectional TVS diode, indicated by its single cathode band and specified reverse standoff voltage of 12.8V. It is intended for DC rail protection only and must be oriented with cathode toward the protected line; using it in AC or bidirectional configurations requires external circuitry and is not supported by its qualification.
Does JANTXV1N6119AUS/TR require derating at elevated temperatures?
Yes - the JANTXV1N6119AUS/TR exhibits positive temperature coefficient for breakdown voltage, increasing ~0.1% per °C above 25°C. At +175°C, VBR rises to approximately 16.5V, requiring system-level validation of clamping margin. Derating curves are provided in Microchip's MIL-PRF-19500/530 compliance report for JANTXV1N6119AUS/TR.
What is the lead finish and plating specification for JANTXV1N6119AUS/TR?
JANTXV1N6119AUS/TR features solder-dipped leads with 100% tin plating over copper alloy, compliant with MIL-STD-750 Method 2074. The finish supports wave and reflow soldering per MIL-STD-202, and the axial leads are tinned to 100% coverage for reliable interconnect in high-vibration aerospace assemblies.
Can JANTXV1N6119AUS/TR be used in parallel for higher surge capacity?
No - JANTXV1N6119AUS/TR is not characterized for parallel operation due to mismatch in dynamic impedance and avalanche turn-on timing. Parallel use risks current hogging and premature failure; for >400W protection, select a higher-rated single device such as JANTXV1N6122AUS/TR rather than paralleling multiple JANTXV1N6119AUS/TR units.
