Product details
Overview
JANTXV1N6142US/TR from Microsemi is a hermetically sealed, voidless, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV level. It provides 7.6 V working standoff voltage (VWM), 9.50 V minimum breakdown voltage (V(BR)) at 125 mA, and clamps transients to 14.5 V at 103.4 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in high-reliability military power rail protection.
For engineers reviewing the JANTXV1N6142US/TR datasheet, JANTXV1N6142US/TR pinout, JANTXV1N6142US/TR application, or JANTXV1N6142US/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 surface-mount reflow.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses hard-glass construction with tungsten slugs for thermal robustness. Its clamping behavior is defined by a 14.5 V VC at 103.4 A IPP under 10/1000 µs surge, supported by a low 5.0 °C/W junction-to-end-cap thermal resistance (RθJEC) enabling sustained power dissipation up to 5.0 W at TEC = 150 °C.
The device meets IEC61000-4-2 ESD and IEC61000-4-4 EFT immunity requirements, and provides lightning-induced surge protection per select levels of IEC61000-4-5. Its 0.07 %/°C temperature coefficient of V(BR) ensures stable breakdown across military temperature extremes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6142US | Commercial-grade version; not MIL-qualified; same electrical specs but no JANTXV reliability screening | Lacks MIL-PRF-19500/516 qualification; unsuitable for flight-critical or DoD procurement | Select when cost-sensitive prototyping or non-military industrial use demands identical clamping performance without screening overhead |
| JANTXV1N6141US/TR | Lower VWM (6.9 V), lower VC (13.4 V), higher IPP (111.9 A); otherwise identical package and qualification | Better suited for 6–7 V rail protection where tighter clamping margin is required | Choose when protecting sub-7 V logic supplies or when lower clamping voltage justifies trade-off in standoff headroom |
Compared with JANTXV1N6142US/TR, the commercial 1N6142US omits military screening but retains full electrical equivalence, while JANTXV1N6141US/TR offers tighter clamping at reduced standoff - enabling precise rail-specific surge design without changing layout or thermal management.

FAQ
What is the maximum clamping voltage of the JANTXV1N6142US/TR under standard test conditions?
The JANTXV1N6142US/TR has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10/1000 µs surge waveform at its rated peak pulse current of 103.4 A. This value is measured per MIL-PRF-19500/516 test methods and defines the upper voltage limit imposed on protected circuitry during transient events. The JANTXV1N6142US/TR maintains this clamping performance across its full -55 °C to +175 °C operating junction temperature range.
Is the JANTXV1N6142US/TR compatible with lead-free reflow soldering processes?
The JANTXV1N6142US/TR features tin/lead plated copper terminations and is rated for a maximum solder temperature of 260 °C for 10 seconds, making it compatible with standard SnPb reflow profiles. While RoHS-compliant matte-tin versions exist for commercial-grade parts, the JANTXV1N6142US/TR itself is not RoHS-compliant and must be processed using leaded solder. Its SQ-MELF "C" package geometry supports reliable wetting and alignment during automated placement.
Does the JANTXV1N6142US/TR require polarity-aware PCB layout?
No - the JANTXV1N6142US/TR is a bidirectional TVS with no polarity marking or internal asymmetry, so either end may connect to either side of the protected line. This eliminates orientation errors during assembly and simplifies layout for differential or AC-coupled signals. The JANTXV1N6142US/TR achieves symmetrical clamping behavior due to its hermetically sealed, voidless glass construction and Category 1 metallurgical bonds on both terminals.
How does the JANTXV1N6142US/TR meet MIL-PRF-19500/516 qualification requirements?
The JANTXV1N6142US/TR undergoes full JANTXV-level screening per MIL-PRF-19500/516, including temperature cycling, steady-state life testing, and surge endurance validation. It incorporates triple-layer passivation, voidless hermetic sealing, and internal Category 1 metallurgical bonds - all verified through destructive physical analysis. These features ensure the JANTXV1N6142US/TR sustains performance in extreme environments where commercial alternatives would degrade.
What is the standby leakage current of the JANTXV1N6142US/TR at its rated standoff voltage?
The JANTXV1N6142US/TR exhibits a maximum standby current (ID) of 100 µA when biased at its rated working standoff voltage (VWM) of 7.6 V. This low leakage preserves power efficiency in always-on military subsystems and avoids false triggering in high-impedance sensing circuits. The JANTXV1N6142US/TR maintains this ID specification across its full operating temperature range and after extended life testing per MIL-PRF-19500/516.
