Product details
Overview
JANTX1N6141US/TR from Microsemi is a military-qualified, voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF (C) package. It provides 6.9 V working standoff voltage (VWM), 8.65 V minimum breakdown voltage (V(BR)) at 150 mA, and clamps transients to 13.4 V at 111.9 A peak pulse current (IPP) for 10/1000 µs waveform - delivering 1500 W peak pulse power in high-reliability aerospace and defense power rail protection.
For engineers reviewing the JANTX1N6141US/TR datasheet, JANTX1N6141US/TR pinout, JANTX1N6141US/TR application, or JANTX1N6141US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTX qualification, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and compatibility with automated surface-mount assembly under 260 °C solder profile.
Technical Context
This TVS operates bidirectionally with no polarity marking and relies on hard-glass construction with internal Category 1 metallurgical bonds for radiation hardness and long-term reliability under thermal cycling. Its clamping action begins above 6.9 V (VWM) and fully engages at 8.65 V (V(BR)), limiting surge energy to safe levels for downstream circuitry.
The device sustains 1500 W peak pulse power per 10/1000 µs waveform while maintaining ≤13.4 V clamping voltage at 111.9 A IPP. Thermal performance is defined by junction-to-end-cap resistance of 5.0 °C/W, enabling stable operation up to +175 °C junction temperature when properly mounted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.9 V - Maximum continuous DC or repetitive peak voltage the device blocks without conduction. |
| V(BR) min | 8.65 V @ 150 mA - Minimum voltage at which the device enters avalanche breakdown, defining turn-on threshold. |
| VC @ IPP | 13.4 V @ 111.9 A - Clamping voltage during 10/1000 µs transient, directly limiting stress on protected ICs. |
| PPP | 1500 W - Peak impulse power handling capability, critical for lightning-induced surge immunity per IEC61000-4-5. |
| ID @ VWM | 100 µA - Standby leakage current at rated standoff voltage, ensuring minimal power loss in quiescent state. |
| TJ Range | –55 °C to +175 °C - Full military-grade operating junction temperature range, validated for harsh-environment deployment. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance, enabling accurate thermal design for end-cap heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6141US/TR (commercial grade) | No MIL-PRF-19500/516 qualification; same electrical specs but no JANTX screening or extended temp validation. | Suitable only for non-mission-critical commercial systems with ambient temp < +125 °C and no radiation exposure. | Select when cost sensitivity outweighs reliability requirements and full military screening is unnecessary. |
| JANTXV1N6141US/TR | Higher screening level (JANTXV): includes 100% lot testing, enhanced burn-in, and tighter parametric limits per MIL-PRF-19500/516. | Required for spaceflight avionics, nuclear command systems, or platforms demanding zero latent defects. | Choose when mission-critical failure modes must be eliminated and lifetime reliability exceeds 15 years. |
Compared with 1N6141US/TR and JANTXV1N6141US/TR, JANTX1N6141US/TR delivers verified mid-tier reliability - qualified to JANTX level with full screening but without JANTXV's 100% lot testing - making it optimal for defense electronics where proven robustness meets program budget constraints.

FAQ
What is the maximum clamping voltage of JANTX1N6141US/TR under standard test conditions?
The JANTX1N6141US/TR has a maximum clamping voltage (VC) of 13.4 V when subjected to a 10/1000 µs surge waveform at 111.9 A peak pulse current (IPP). This value is measured per MIL-STD-883 and defines the upper voltage limit imposed on protected circuitry during transient events. The JANTX1N6141US/TR maintains this clamping performance across its full –55 °C to +175 °C junction temperature range.
Is JANTX1N6141US/TR compatible with lead-free reflow processes?
JANTX1N6141US/TR is rated for a maximum solder temperature of 260 °C for 10 seconds, aligning with industry-standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020). Its tin/lead-plated terminals are designed for compatibility with both SnPb and Pb-free assembly, though RoHS-compliant matte-tin versions are available only in commercial-grade variants, not JANTX.
Does JANTX1N6141US/TR require polarity-aware PCB layout?
No - JANTX1N6141US/TR is a bidirectional TVS with symmetrical terminals and no polarity marking. Its SQ-MELF (C) package allows unrestricted orientation during placement. The device clamps transients equally in both directions, making it ideal for AC-coupled lines, floating grounds, or differential buses where polarity cannot be guaranteed.
How does JANTX1N6141US/TR differ from the non-A version (e.g., JANTX1N6141US/TR vs. JANTX1N6141US/TR without 'A' suffix)?
The 'A' suffix in JANTX1N6141US/TR indicates tighter voltage tolerances: minimum breakdown voltage is 8.65 V (vs. 5% lower for non-A), clamping voltage is 13.4 V (vs. 5% higher for non-A), and peak pulse current is 111.9 A (vs. 5% lower for non-A). These differences reflect stricter binning and screening applied to the 'A' variant per Microsemi's nomenclature specification.
What thermal mounting guidance applies to JANTX1N6141US/TR in high-power surge scenarios?
JANTX1N6141US/TR uses an end-cap thermal path with RθJEC = 5.0 °C/W. For sustained surge duty, mount both ends to thermally conductive PCB pads sized per the recommended 0.205" × 0.245" footprint, and consider optional center adhesive spot (0.090" diameter) for mechanical stability. Avoid thermal vias under the glass body - heat flows axially through the end caps, not radially into the board.
