Product details
Overview
JANTXV1N6141US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package, rated for 1500 W peak pulse power (10/1000 µs), 6.9 V working standoff voltage (VWM), 8.65 V minimum breakdown voltage (VBR @ 150 mA), and 13.4 V clamping voltage (VC @ 111.9 A). It serves as primary surge protection in high-reliability avionics power interfaces.
For engineers reviewing the JANTXV1N6141US/TR datasheet, JANTXV1N6141US/TR pinout, JANTXV1N6141US/TR application, or JANTXV1N6141US/TR equivalent, key selection criteria include MIL-PRF-19500/516 JANTXV qualification level, bidirectional clamping behavior, 1100 mg mass constraint, thermal resistance of 5.0 °C/W (junction-to-end cap), and compatibility with EIA-481-B tape-and-reel handling.
Technical Context
This device operates as a bidirectional avalanche diode-based TVS, leveraging hard-glass hermetic construction with internal Category 1 metallurgical bonds to sustain repeated 1500 W transients without degradation. Its clamping response is defined by VC = 13.4 V at IPP = 111.9 A under 10/1000 µs waveform, with temperature coefficient αVBR = 0.06 %/°C ensuring stable breakdown across –55 °C to +175 °C junction range.
No polarity marking is present due to symmetrical bidirectional conduction. Standby current remains ≤100 µA at VWM = 6.9 V, and it meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and select IEC61000-4-5 (lightning secondary effects) immunity requirements without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.9 V - Maximum continuous reverse voltage before leakage exceeds 100 µA; sets upper limit for protected line operating voltage. |
| VBR min | 8.65 V @ 150 mA - Minimum voltage at which avalanche conduction begins; defines turn-on threshold under DC stress. |
| VC | 13.4 V @ 111.9 A - Clamped voltage during 10/1000 µs transient; determines maximum stress on downstream ICs. |
| PPP | 1500 W - Peak pulse power rating; enables protection against MIL-STD-1275B and DO-160 Section 22 induced surges. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance; supports direct heat sinking via end caps in conduction-cooled modules. |
| TJ/TSTG | –55 °C to +175 °C - Full military temperature range; validated for operation in engine bay and space-grade electronics. |
| αVBR | 0.06 %/°C - Temperature coefficient of breakdown voltage; ensures <±0.5 V drift over full operating range. |
Pinout & Package
Package: SQ-MELF (Square-End-Cap Metal Electrode Leadless Face), hermetically sealed voidless hard glass case with tungsten slugs and tin/lead-plated copper terminals. Weight ≈1100 mg. Dimensions: BD = 4.65–5.13 mm, BL = 5.21–6.22 mm, ECT = 0.48–0.71 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No polarity marking required; either end functions identically as transient clamp node in AC or DC lines. |
| End Cap (both ends) | Thermal and electrical termination | Provides low-inductance current path and primary heat dissipation surface; requires solder pad contact per EIA-481-B layout. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Eliminates moisture ingress and internal delamination risk over 20+ year field life in vacuum or humid environments. |
| Category 1 metallurgical bonds | Ensures mechanical integrity under shock/vibration per MIL-STD-883 Method 2002, critical for airborne radar systems. |
| MIL-PRF-19500/516 JANTXV qualification | Validated reliability at 100% screening, burn-in, and lot acceptance testing-required for DoD procurement contracts. |
| Triple-layer passivation | Prevents surface leakage and contamination-induced parameter shift during long-term storage or reflow exposure. |
| IEC61000-4-5 compliance (select levels) | Enables direct integration into lightning-susceptible subsystems (e.g., aircraft landing gear control) without external filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6140US/TR | VWM = 6.2 V, VBR min = 7.79 V, VC = 12.1 V @ 124.0 A - lower clamping but reduced standoff margin. | Better suited for 5 V logic rail protection where tighter VWM headroom is required. | Select when system nominal voltage is ≤6.0 V and clamping voltage must stay below 12.5 V. |
| JANTXV1N6142US/TR | VWM = 7.6 V, VBR min = 9.50 V, VC = 14.5 V @ 103.4 A - higher standoff but increased clamping voltage. | Preferred for 12 V automotive-derived subsystems requiring wider VWM margin against ripple. | Choose when protecting 8–10 V regulated supplies where VWM > 7.0 V prevents false triggering. |
Compared with JANTXV1N6141US/TR, JANTXV1N6140US/TR offers lower clamping at the cost of reduced standoff headroom, while JANTXV1N6142US/TR increases robustness against overvoltage nuisance tripping but raises downstream voltage stress during clamping-requiring careful trade-off analysis per circuit sensitivity.

FAQ
What is the maximum clamping voltage of JANTXV1N6141US/TR under standard test conditions?
The JANTXV1N6141US/TR has a maximum clamping voltage (VC) of 13.4 V when subjected to a 10/1000 µs impulse current of 111.9 A. This value is measured per MIL-STD-883 Method 3012 and is guaranteed across the full –55 °C to +175 °C junction temperature range. The JANTXV1N6141US/TR maintains this clamping performance without degradation after repeated surge events, supporting long-term reliability in harsh environments.
Is JANTXV1N6141US/TR compatible with lead-free reflow processes?
JANTXV1N6141US/TR is not RoHS-compliant and uses tin/lead plating per MIL-PRF-19500/516 requirements; its maximum solder temperature rating is 260 °C for 10 seconds. Lead-free reflow profiles exceeding 260 °C or prolonged exposure above 240 °C may compromise hermeticity or metallurgical bond integrity. The JANTXV1N6141US/TR must be processed using SnPb-compatible thermal profiles to maintain qualification validity.
Does JANTXV1N6141US/TR require polarity-aware PCB layout?
No. The JANTXV1N6141US/TR is a bidirectional TVS with symmetrical avalanche characteristics; its terminals are electrically interchangeable and carry no polarity marking. PCB layout may orient either end toward the protected line or ground-no silkscreen polarity indicator is needed. This simplifies placement in differential or AC-coupled circuits and eliminates orientation errors during automated assembly of the JANTXV1N6141US/TR.
How does JANTXV1N6141US/TR perform under high-temperature operating conditions?
JANTXV1N6141US/TR is rated for continuous operation from –55 °C to +175 °C junction temperature, with linear power derating applied above +150 °C end-cap temperature. At +125 °C ambient, its steady-state power dissipation remains within 3.0 W limits when mounted on thermally optimized PCBs. The JANTXV1N6141US/TR exhibits no parameter shift or reliability loss in accelerated life testing at 175 °C for 1000 hours, confirming suitability for engine-mounted electronics.
Can JANTXV1N6141US/TR be used in place of commercial-grade 1N6141AUS?
No. JANTXV1N6141US/TR and 1N6141AUS differ in screening, testing, and qualification: the former is fully MIL-PRF-19500/516 JANTXV-qualified with 100% lot testing, burn-in, and radiation hardness validation, while the latter is commercial-grade only. Substituting JANTXV1N6141US/TR for 1N6141AUS is permissible in high-reliability designs, but replacing JANTXV1N6141US/TR with 1N6141AUS invalidates military certification and voids warranty for defense applications involving the JANTXV1N6141US/TR.
