Product details
Overview
JANTXV1N6144US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV reliability level. It provides 9.1 V working standoff voltage (VWM), 11.40 V minimum breakdown voltage (V(BR)) at 100 mA, and clamps transients to 16.9 V at 88.8 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in military avionics power rail protection.
For engineers reviewing the JANTXV1N6144US/TR datasheet, JANTXV1N6144US/TR pinout, JANTXV1N6144US/TR application, or JANTXV1N6144US/TR equivalent, key selection criteria include its 1500 W peak pulse power rating, -55 °C to +175 °C operating junction temperature range, Category 1 metallurgical bonds, RoHS-compliant tin/lead terminations, and SQ-MELF "C" package compatibility with EIA-481-B tape-and-reel handling.
Technical Context
This TVS operates bidirectionally with no polarity marking and relies on hard-glass construction with tungsten slugs for thermal robustness. Its clamping behavior is defined by a 16.9 V VC at 88.8 A IPP under 10/1000 µs surge, supported by a low 5.0 °C/W junction-to-end-cap thermal resistance (RθJEC) enabling high-energy transient dissipation without thermal runaway.
The device meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and select levels of IEC61000-4-5 (lightning-induced surges). Its 0.07 %/°C temperature coefficient of V(BR) ensures stable breakdown voltage across extended military temperature ranges, and it is inherently radiation-hard per MicroNote 050.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.1 V - maximum continuous reverse standoff voltage before conduction begins; sets system-level overvoltage trip threshold |
| V(BR) min | 11.40 V @ 100 mA - guaranteed breakdown onset; defines minimum clamping margin above VWM |
| VC @ IPP | 16.9 V @ 88.8 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient exposure |
| PPP | 1500 W - peak pulse power handling for 10/1000 µs waveform; enables protection against high-energy lightning-induced transients |
| TJ Range | -55 °C to +175 °C - full military-grade junction temperature range; supports operation in engine bays and space-constrained avionics enclosures |
| RθJEC | 5.0 °C/W - low thermal resistance from junction to end cap; allows efficient heat transfer to PCB copper or heatsink |
| ID @ VWM | 20 µA - ultra-low leakage at rated standoff; prevents excessive standby power loss in battery-backed systems |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs; tin/lead plated copper terminals; weight ≈1100 mg; dimensions per Microsemi T4-LDS-0278-1 Rev. 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path | No polarity marking; symmetric conduction in either direction; both ends serve as interchangeable surge entry/exit points |
| End Cap (glass body contact) | Thermal interface | Primary heat conduction path to PCB pad or heatsink; requires direct metal-to-metal contact for RθJEC = 5.0 °C/W performance |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal/power lines without polarity concerns |
| Category 1 metallurgical bonds | Ensures mechanical integrity and bond-wire reliability under shock/vibration stress in aerospace platforms |
| Voidless hermetic seal | Prevents moisture ingress and internal corrosion over 20+ year service life in humid or salt-laden environments |
| MIL-PRF-19500/516 qualification | Validates manufacturing process control, screening, and lot traceability required for flight-critical subsystems |
| Triple-layer passivation | Reduces surface leakage and enhances long-term stability of V(BR) under high-humidity and high-bias conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6144US | Same electrical specs but supplied in bulk (not tape-and-reel); lacks TR suffix indicating carrier packaging | Preferred for manual prototyping or low-volume hand-soldered assemblies where reel feeding is unnecessary | Select JANTXV1N6144US/TR when automated SMT placement is required; choose JANTXV1N6144US for bench evaluation or repair spares |
| 1N6144AUS | Commercial-grade version; same VWM, V(BR), VC, and IPP but not MIL-qualified; RoHS-compliant matte-tin terminations available | Suitable for non-mission-critical industrial controls where MIL-PRF-19500/516 screening is not mandated | Use 1N6144AUS only in commercial programs with relaxed reliability requirements; JANTXV1N6144US/TR remains mandatory for defense prime contracts |
Compared with JANTXV1N6144US/TR, JANTXV1N6144US offers identical protection performance but lacks tape-and-reel logistics support, while 1N6144AUS sacrifices military qualification and long-term reliability assurance for lower cost and RoHS compliance - making JANTXV1N6144US/TR the sole choice for JANTXV-level traceability and radiation-hardened deployment.

FAQ
What is the clamping voltage of JANTXV1N6144US/TR under standard 10/1000 µs surge conditions?
The JANTXV1N6144US/TR clamps to a maximum of 16.9 V when subjected to an 88.8 A peak pulse current (IPP) with a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and is guaranteed across the full -55 °C to +175 °C junction temperature range. The clamping voltage directly determines the maximum overvoltage seen by downstream circuitry, making it critical for protecting 12 V and 28 V rail-sensitive ICs. JANTXV1N6144US/TR maintains this specification under all qualified screening conditions.
Is JANTXV1N6144US/TR compatible with lead-free reflow processes?
JANTXV1N6144US/TR uses tin/lead (SnPb) terminations and is rated for solder temperature up to 260 °C for 10 seconds, matching standard SnPb reflow profiles. It is not qualified for lead-free (RoHS-compliant) reflow, which typically exceeds 260 °C peak. For RoHS-compliant alternatives, the commercial-grade 1N6144AUS variant is available with matte-tin terminations - but JANTXV1N6144US/TR itself must be processed using SnPb-compatible thermal profiles to maintain MIL-PRF-19500/516 qualification integrity.
Does JANTXV1N6144US/TR require polarity-aware PCB layout?
No - JANTXV1N6144US/TR is a bidirectional TVS with no polarity marking and symmetric electrical characteristics in both directions. Its SQ-MELF "C" package has identical end-cap geometry, allowing unrestricted orientation during placement. This eliminates risk of misorientation during automated assembly and simplifies layout for AC-coupled or floating interfaces. The absence of polarity dependence is confirmed in the nomenclature section of T4-LDS-0278-1 Rev. 2, which explicitly states "No polarity marking for these bidirectional TVSs." JANTXV1N6144US/TR functions identically regardless of terminal assignment.
What is the maximum steady-state power dissipation of JANTXV1N6144US/TR at 25 °C ambient?
JANTXV1N6144US/TR has a steady-state power rating of 3.0 W at TA = 25 °C, as specified in the Maximum Ratings table of T4-LDS-0278-1 Rev. 2. This value assumes adequate PCB copper area for thermal conduction and applies only to continuous DC or low-frequency operation - not transient suppression duty cycles. Derating is required above 25 °C ambient per Figure 4, reaching zero power at 150 °C end-cap temperature. JANTXV1N6144US/TR's 5.0 °C/W RθJEC enables higher sustained power if end-cap cooling is implemented.
How does JANTXV1N6144US/TR meet IEC61000-4-5 lightning surge requirements?
JANTXV1N6144US/TR provides protection against secondary effects of lightning per select levels of IEC61000-4-5, as stated in the Applications/Benefits section of its datasheet. Its 1500 W peak pulse power rating and 16.9 V clamping voltage at 88.8 A IPP enable effective suppression of combination wave surges (1.2/50 µs voltage, 8/20 µs current) up to Level 4 (4 kV line-earth, 2 kV line-line) when properly integrated with impedance-matching PCB layout and upstream current-limiting resistors. JANTXV1N6144US/TR's hard-glass construction and Category 1 bonds ensure survivability across repeated surges without parameter drift.
