Product details
Overview
JANTXV1N6145US/TR from Microsemi is a voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV level. It provides 9.9 V working standoff voltage (VWM), 12.35 V minimum breakdown voltage (V(BR)) at 100 mA, and clamps transients to 18.2 V at 82.4 A peak pulse current (IPP), delivering 1500 W peak pulse power for 10/1000 µs waveform in high-reliability military avionics power rail protection.
For engineers reviewing the JANTXV1N6145US/TR datasheet, JANTXV1N6145US/TR pinout, JANTXV1N6145US/TR application, or JANTXV1N6145US/TR equivalent, this part supports ESD/EFT protection per IEC61000-4-2/-4-4, lightning-induced surge suppression per IEC61000-4-5, and operates across –55 °C to +175 °C junction temperature with Category 1 metallurgical bonds and triple-layer passivation.
Technical Context
This TVS diode uses hard-glass hermetic construction with tungsten slugs and tin/lead-plated copper terminals, enabling robust transient energy absorption without void formation. Its bidirectional architecture eliminates polarity concerns and supports symmetric clamping on both positive and negative excursions.
The device achieves 1500 W peak pulse power (10/1000 µs) with thermal resistance of 5.0 °C/W (junction-to-end cap), and linearly derates from 5.0 W off-state power at TEC = 150 °C to zero at 175 °C. Standby current remains ≤20 µA at 9.9 V VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.9 V - Maximum continuous DC or repetitive peak voltage applied without triggering conduction. |
| V(BR) min | 12.35 V @ 100 mA - Guaranteed breakdown onset under standardized test current; defines turn-on threshold. |
| VC @ IPP | 18.2 V @ 82.4 A - Clamped voltage during full-rated 10/1000 µs surge; determines protected circuit stress level. |
| PPP | 1500 W - Peak transient power handling capability for standard lightning-surge waveform. |
| TJ Range | –55 °C to +175 °C - Full military-grade operating junction temperature range without derating loss. |
| RθJEC | 5.0 °C/W - Thermal resistance from junction to end cap; enables direct heatsinking via PCB pads or mounting surface. |
Pinout & Package
Package: Hermetically sealed voidless hard-glass "C" package (SQ-MELF style), with square-end-cap terminals for precise SMT placement. Dimensions: BD = 0.183–0.202 in (4.65–5.13 mm), BL = 0.205–0.245 in (5.21–6.22 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | No polarity marking; either terminal serves as anode or cathode depending on transient polarity - enables single-device bidirectional clamping. |
| End Cap (both ends) | Thermal & electrical interface | Direct metal-to-PCB contact for low-inductance surge return path and junction heat extraction (RθJEC = 5.0 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic seal | Eliminates internal delamination risk under thermal cycling or high-humidity operation - critical for 20+ year field life in aerospace systems. |
| Category 1 metallurgical bonds | Internal tungsten-copper interconnects withstand >100,000 thermal cycles and >50 g mechanical shock without bond fatigue. |
| Triple-layer passivation | SiO₂/Si₃N₄/SiO₂ stack prevents moisture ingress and ion migration - maintains V(BR) stability after 1000 hrs @ 85 °C/85% RH. |
| MIL-PRF-19500/516 JANTXV qualification | Includes lot traceability, 100% burn-in, and parametric screening per MIL-STD-750 - ensures zero infant mortality in deployed hardware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6145US/TR | Commercial-grade version; same VWM (9.9 V), VC (18.2 V), and PPP (1500 W), but not MIL-qualified - no JANTXV screening or lot traceability. | Lacks MIL-PRF-19500/516 qualification; unsuitable for DoD procurement or space-qualified designs. | Select only for non-military industrial prototypes where cost sensitivity outweighs long-term reliability assurance. |
| JANTXV1N6144US/TR | Lower VWM (9.1 V), lower V(BR) min (11.40 V), higher IPP (88.8 A), identical PPP (1500 W) and package. | Better suited for 9 V nominal systems; tighter clamping margin vs. 9.9 V rail but reduced headroom before conduction. | Choose when protecting circuits with lower absolute maximum input ratings - e.g., legacy 9 V analog sensors or microcontrollers. |
Compared with JANTXV1N6145US/TR, the commercial 1N6145US/TR omits military screening and traceability but matches electrical specs, while JANTXV1N6144US/TR offers lower standoff for tighter 9 V system margins - neither is pin-compatible drop-in due to distinct VWM/V(BR) design points requiring layout review.

FAQ
What is the maximum clamping voltage of JANTXV1N6145US/TR under full-rated surge conditions?
The JANTXV1N6145US/TR clamps to a maximum of 18.2 V when subjected to its rated 82.4 A peak pulse current (IPP) with a 10/1000 µs waveform. This value is guaranteed across the full –55 °C to +175 °C junction temperature range and forms the basis for downstream circuit overvoltage margining in designs using JANTXV1N6145US/TR.
Is JANTXV1N6145US/TR RoHS compliant?
No, JANTXV1N6145US/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants (e.g., 1N6145AUS), not for JANTXV-level military-qualified parts like JANTXV1N6145US/TR, which retain tin/lead plating for enhanced solder joint reliability under thermal cycling.
Does JANTXV1N6145US/TR require polarity-aware PCB layout?
No, JANTXV1N6145US/TR is a bidirectional TVS and has no polarity marking. Either end functions identically as anode or cathode depending on transient polarity, allowing orientation-agnostic placement on PCBs - a key advantage for compact, high-density military layouts where routing flexibility is constrained.
What is the thermal resistance specification for JANTXV1N6145US/TR, and how does it impact heatsinking?
JANTXV1N6145US/TR has a junction-to-end cap thermal resistance (RθJEC) of 5.0 °C/W. This low value enables effective heat extraction through direct end-cap contact with copper pads or metal-core PCBs, supporting sustained off-state power dissipation up to 5.0 W at TEC = 150 °C - critical for thermal management in sealed avionics enclosures.
How does JANTXV1N6145US/TR differ from the "A" suffix variant 1N6145AUS?
JANTXV1N6145US/TR and 1N6145AUS share identical electrical parameters (VWM = 9.9 V, V(BR) min = 12.35 V, VC = 18.2 V), but differ in qualification: JANTXV1N6145US/TR is fully MIL-PRF-19500/516 qualified at JANTXV level with 100% screening, while 1N6145AUS is commercial-grade with no military testing or traceability - making JANTXV1N6145US/TR mandatory for DoD contracts.
