Product details
Overview
JANTXV1N6168AUS/TR from Microsemi is a military-qualified, voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) designed for high-reliability circuit protection. It features a 91.2 V working standoff voltage (VWM), 114.0 V minimum breakdown voltage (V(BR)) at 10 mA, 165.1 V clamping voltage (VC) at 9.1 A peak pulse current (IPP), and 1500 W peak pulse power (10/1000 µs). It is used in avionics power bus conditioning and radiation-hardened satellite interface circuits.
For engineers reviewing the JANTXV1N6168AUS/TR datasheet, JANTXV1N6168AUS/TR pinout, JANTXV1N6168AUS/TR application, or JANTXV1N6168AUS/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTXV qualification, Category 1 metallurgical bonds, -55°C to +175°C operating junction temperature, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning surge immunity.
Technical Context
This TVS operates bidirectionally with no polarity marking and relies on hard-glass construction with tungsten slugs for thermal stability and mechanical robustness. Its triple-layer passivation and internal Category 1 metallurgical bonds ensure long-term reliability under thermal cycling and radiation exposure per MicroNote 050.
The device delivers 1500 W peak pulse power for 10/1000 µs transients while maintaining a low thermal resistance of 5.0 °C/W (junction-to-end cap). Standby current is limited to ≤5 µA at 91.2 V, and it exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.100 %/°C - critical for precision overtemperature operation in aerospace systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 91.2 V - Maximum continuous reverse standoff voltage before conduction begins; defines maximum system operating voltage it can protect without leakage. |
| V(BR) min | 114.0 V @ 10 mA - Minimum voltage at which device enters controlled avalanche; ensures predictable turn-on margin above VWM. |
| VC @ IPP | 165.1 V @ 9.1 A - Clamping voltage during 10/1000 µs transient; determines maximum stress imposed on downstream ICs. |
| PPP | 1500 W - Peak pulse power handling capability; enables protection against high-energy surges like lightning-induced coupling. |
| TJ Range | -55°C to +175°C - Full military-grade junction temperature range; supports operation in extreme environments without derating loss. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance; allows direct thermal path design into PCB copper or heatsink for sustained pulse duty. |
| αV(BR) | 0.100 %/°C - Temperature coefficient of breakdown voltage; enables accurate overtemperature clamping prediction in flight control systems. |
Pinout & Package
Package: Hermetically sealed voidless hard-glass "C" package (SQ-MELF style), surface-mount, square-end-cap terminals, ~1100 mg weight. 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) | Reversible current path | No polarity marking required; symmetric conduction in either direction enables single-device protection of AC or differential lines. |
| End Cap (both ends) | Thermal and electrical terminal | Directly bonded tungsten slug provides low-inductance current path and primary heat dissipation route to PCB pads. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional TVS architecture | Enables single-device protection of AC-coupled, differential, or floating signal/power rails without polarity concerns. |
| Category 1 metallurgical bonds | Guarantees bond integrity under thermal shock and vibration per MIL-STD-750, critical for launch and orbital deployment. |
| Triple-layer passivation | Prevents moisture ingress and surface leakage in high-humidity or vacuum-outgassing environments typical in space payloads. |
| JANTXV qualification | Fully screened to MIL-PRF-19500/516 Level JANTXV - includes burn-in, life test, and lot acceptance testing for mission-critical use. |
| Radiation hardness | Inherently radiation-tolerant per MicroNote 050; validated for total ionizing dose (TID) >100 krad(Si) without parameter shift. |
Applications
| Aerospace Power Bus Protection | Satellite Command & Data Handling Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6168US/TR | Commercial-grade version; lacks JANTXV screening, no MIL-PRF-19500/516 qualification, higher VC tolerance (±5% vs. tighter JANTXV limits). | Approved only for non-mission-critical ground test equipment or commercial subsystems; not rated for flight hardware. | Select when cost sensitivity outweighs radiation tolerance and extended temperature validation requirements. |
| JANTXV1N6167AUS/TR | Lower VWM (86.6 V), lower VC (151.3 V @ 9.9 A); otherwise identical construction, qualification, and packaging. | Better suited for 24–48 V intermediate bus protection where tighter clamping headroom is needed. | Choose when system nominal voltage is ≤80 V and lower clamping voltage is prioritized over maximum standoff margin. |
Compared with JANTXV1N6168AUS/TR, the commercial 1N6168US/TR omits military screening and radiation assurance, while JANTXV1N6167AUS/TR trades 4.6 V VWM margin for 13.8 V lower clamping - enabling safer protection of 75 V-rated FETs but reducing headroom for 100 V transients.

FAQ
What is the clamping voltage of JANTXV1N6168AUS/TR at its rated peak pulse current?
The JANTXV1N6168AUS/TR has a maximum clamping voltage (VC) of 165.1 V when subjected to its rated peak pulse current (IPP) of 9.1 A under the standard 10/1000 µs waveform. This value is guaranteed per the manufacturer's electrical characteristics table and reflects worst-case device behavior after full MIL-PRF-19500/516 screening.
Is JANTXV1N6168AUS/TR RoHS compliant?
No, JANTXV1N6168AUS/TR is not RoHS compliant. Per the nomenclature and features section, RoHS-compliant matte-tin terminations are available only on commercial-grade versions (e.g., 1N6168AUS/TR without JANTXV prefix). The JANTXV variant uses traditional tin/lead plating to meet MIL-STD-750 solderability and reliability requirements.
Does JANTXV1N6168AUS/TR require polarity-aware PCB layout?
No, JANTXV1N6168AUS/TR is a bidirectional TVS with no polarity marking and symmetric electrical characteristics. Its SQ-MELF "C" package has identical end-cap terminals, allowing orientation-agnostic placement on PCBs - simplifying layout and eliminating risk of reverse installation in high-density avionics assemblies.
What is the thermal resistance from junction to end cap for JANTXV1N6168AUS/TR?
The thermal resistance from junction to end cap (RθJEC) for JANTXV1N6168AUS/TR is 5.0 °C/W, as specified in the Maximum Ratings table. This low value enables efficient heat transfer directly from the silicon die through the tungsten slugs into the PCB copper pads, supporting repeated 1500 W pulse handling without thermal runaway.
How does JANTXV1N6168AUS/TR differ from the non-A suffix version (e.g., JANTXV1N6168US/TR)?
JANTXV1N6168AUS/TR features tighter electrical tolerances: its minimum breakdown voltage (V(BR)) is 5% higher, clamping voltage (VC) is 5% lower, and peak pulse current (IPP) is 5% higher than the non-A version. These improvements result from enhanced process control and screening - critical for applications demanding precise clamping predictability in safety-critical systems.
