Product details
Overview
JANTXV1N6161US/TR from Microsemi is a voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV level. It provides 47.1 V working peak standoff voltage (VWM), 58.9 V minimum breakdown voltage (V(BR)) at 20 mA, and clamps transients to 85.3 V at 17.6 A peak pulse current (IPP) for 10/1000 µs waveform. It delivers 1500 W peak pulse power and operates from –55 °C to +175 °C, used in military avionics power rail protection.
For engineers reviewing the JANTXV1N6161US/TR datasheet, JANTXV1N6161US/TR pinout, JANTXV1N6161US/TR application, or JANTXV1N6161US/TR equivalent, key selection criteria include its MIL-qualified reliability, bidirectional clamping behavior, 1500 W surge rating, VWM/V(BR)/VC tolerance stack-up, and SQ-MELF package thermal performance under high-reliability transient stress.
Technical Context
This device is a glass-passivated, hard-glass, bidirectional TVS diode with Category 1 internal metallurgical bonds and triple-layer passivation. Its voidless hermetic seal ensures long-term stability in harsh environments, and it exhibits no polarity marking due to symmetrical bidirectional conduction.
It meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and select levels of IEC61000-4-5 (lightning-induced surges). Thermal resistance junction-to-end cap is 5.0 °C/W, enabling robust power dissipation in surface-mount configurations without external heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 47.1 V - Maximum continuous DC or repetitive peak reverse voltage before clamping initiates; defines safe operating margin below breakdown. |
| V(BR) min | 58.9 V @ 20 mA - Minimum voltage at which device enters avalanche breakdown; sets lower bound for clamping onset threshold. |
| VC @ IPP | 85.3 V @ 17.6 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected downstream circuitry. |
| PPP | 1500 W - Peak pulse power handling capability for standardized 10/1000 µs waveform; defines single-event surge energy limit. |
| ID @ VWM | 5 µA - Standby leakage current at rated standoff voltage; low value minimizes quiescent power loss and signal path loading. |
| TJ Range | –55 °C to +175 °C - Full military-grade junction temperature range; supports operation in extreme environmental conditions without derating. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance; enables direct thermal coupling to PCB copper or chassis for sustained power dissipation. |
Pinout & Package
Package: SQ-MELF (Square-End-Cap Metal Electrode Leadless Face), hermetically sealed voidless hard glass with tungsten slugs; tin/lead-plated copper terminals; weight ≈1100 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Reversible current path | No polarity marking; either end functions identically as cathode or anode depending on transient polarity-enables symmetric placement on PCB without orientation constraints. |
| End Cap (both ends) | Thermal and electrical interface | Directly contacts PCB pads for simultaneous heat conduction and low-inductance current return; eliminates need for dedicated thermal vias or solder mask openings. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or floating signal/power lines without polarity-sensitive layout-reduces BOM count and routing complexity. |
| Category 1 metallurgical bonds | Guarantees bond integrity under thermal cycling and mechanical shock per MIL-PRF-19500/516-critical for aerospace and defense mission-critical systems. |
| Voidless hermetic seal | Prevents moisture ingress and internal corrosion over 20+ year field life-eliminates failure modes associated with plastic-packaged TVS devices in humid or sealed enclosures. |
| Triple-layer passivation | Provides enhanced surface insulation and contamination resistance-maintains stable V(BR) and low ID across extended storage and operational lifetimes. |
| MIL-PRF-19500/516 qualification | Validates manufacturing process control, screening, and test rigor at JANTXV reliability level-required for DoD procurement and flight hardware acceptance. |
Applications
| Avionics Power Distribution | Tactical Radio Front-End Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6161AUS | Commercial-grade version with same VWM (47.1 V), V(BR) (58.9 V), and VC (85.3 V), but not MIL-qualified; RoHS-compliant matte-tin plating available. | Lacks JANTXV screening, burn-in, and lot traceability; unsuitable for DoD or space programs requiring MIL-PRF-19500 compliance. | Select when cost sensitivity outweighs military reliability requirements and RoHS compliance is mandatory. |
| JANTXV1N6160US/TR | Lower VWM (42.6 V), V(BR) (53.2 V), and VC (77.0 V); same 1500 W PPP and SQ-MELF package; identical JANTXV qualification level. | Better suited for 36 V nominal systems where tighter clamping margin is required; slightly higher standby current (5 µA same). | Choose for 36 V rail protection where lower clamping voltage reduces stress on downstream 50 V-rated components. |
Compared with JANTXV1N6161US/TR, 1N6161AUS trades MIL qualification for RoHS compliance and lower cost, while JANTXV1N6160US/TR offers lower clamping voltage at reduced standoff-enabling finer voltage-margin design in 36 V systems without sacrificing surge rating or reliability grade.

FAQ
What is the clamping voltage of JANTXV1N6161US/TR at its rated peak pulse current?
The JANTXV1N6161US/TR has a maximum clamping voltage (VC) of 85.3 V when subjected to its rated peak pulse current (IPP) of 17.6 A under the standard 10/1000 µs waveform. This value is measured per MIL-PRF-19500/516 test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance remains stable across its full operating temperature range.
Is JANTXV1N6161US/TR suitable for RoHS-compliant designs?
No, JANTXV1N6161US/TR uses tin/lead terminal plating and is not RoHS compliant. Microsemi offers RoHS-compliant versions only in commercial-grade parts such as 1N6161AUS. The JANTXV variant maintains legacy plating to ensure compatibility with existing military assembly processes and solderability specifications under MIL-STD-202.
Does JANTXV1N6161US/TR require polarity-aware PCB layout?
No, JANTXV1N6161US/TR is a bidirectional TVS diode with symmetrical electrical characteristics-neither end is marked as anode or cathode. Its SQ-MELF package has identical end caps, allowing unrestricted orientation during automated placement. This eliminates polarity verification steps and reduces assembly errors in high-reliability production lines.
What is the thermal resistance specification for JANTXV1N6161US/TR?
JANTXV1N6161US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W. This parameter reflects direct conduction from the silicon die through the tungsten slug and glass body to the PCB pad contact surface. It enables accurate thermal modeling for steady-state and pulsed power dissipation without requiring additional thermal vias or heatsinks.
How does JANTXV1N6161US/TR differ from commercial 1N6161AUS in reliability testing?
JANTXV1N6161US/TR undergoes full MIL-PRF-19500/516 screening including extended burn-in, temperature cycling, hermeticity testing, and lot acceptance tests per JANTXV level. In contrast, 1N6161AUS receives only commercial-grade quality assurance with no military screening-making it unsuitable for applications requiring guaranteed lifetime performance under shock, vibration, or extreme thermal cycling.
