Product details
Overview
JANTXV1N6156US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV level. It provides 29.7 V working peak standoff voltage (VWM), 37.1 V minimum breakdown voltage (V(BR)) at 30 mA, and clamps transients to 53.6 V at 28.0 A (10/1000 µs), delivering 1500 W peak pulse power for lightning surge and ESD protection in avionics power interfaces.
For engineers reviewing the JANTXV1N6156US/TR datasheet, JANTXV1N6156US/TR pinout, JANTXV1N6156US/TR application, or JANTXV1N6156US/TR equivalent, key selection criteria include its military-grade reliability qualification, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and compatibility with high-reliability PCB assembly under MIL-STD-202 and MIL-STD-750 test conditions.
Technical Context
This TVS operates as a voltage-clamped shunt protector with symmetrical bidirectional conduction-no polarity marking required. Its hard-glass hermetic package uses internal Category 1 metallurgical bonds and triple-layer passivation to ensure robustness against thermal cycling, radiation, and mechanical stress in aerospace and defense systems.
It delivers 1500 W peak pulse power per 10/1000 µs waveform at 25 °C, with linear derating above 150 °C junction temperature and steady-state power capability of 3.0 W at 25 °C ambient. Clamping performance is specified at IPP = 28.0 A, VC = 53.6 V, with VWM = 29.7 V and ID ≤ 5 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 29.7 V - Maximum continuous reverse/forward voltage before clamping initiates; defines operating margin below breakdown. |
| V(BR) min | 37.1 V @ 30 mA - Minimum voltage at which device enters avalanche breakdown; ensures predictable turn-on threshold. |
| VC @ IPP | 53.6 V @ 28.0 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on protected downstream circuitry. |
| PPP | 1500 W - Peak transient energy absorption capacity; supports IEC61000-4-5 Level 3/4 secondary lightning protection. |
| ID @ VWM | ≤5 µA - Leakage current at rated standoff voltage; ensures minimal standby power loss and signal integrity in high-impedance nodes. |
| TJ Range | –55 to +175 °C - Full military temperature range; enables deployment in engine bays, radar housings, and space-qualified electronics. |
Pinout & Package
Package: SQ-MELF (C-package variant), hermetically sealed voidless hard glass with tungsten slugs and tin/lead-plated copper terminals. Dimensions: BD = 0.183–0.202 in (4.65–5.13 mm), BL = 0.205–0.245 in (5.21–6.22 mm), ECT = 0.019–0.028 in (0.48–0.71 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Common terminal pair | No polarity marking; symmetric conduction allows placement without orientation check; both ends function identically under reverse/forward surge. |
| End Cap (both ends) | Thermal & electrical interface | Direct thermal path to PCB pad; RθJEC = 5.0 °C/W enables effective heat dissipation during repetitive surges. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal/power lines without polarity constraints. |
| Category 1 metallurgical bonds | Guarantees bond integrity under shock, vibration, and thermal cycling per MIL-PRF-19500/516 requirements. |
| Triple-layer passivation | Prevents moisture ingress and surface leakage degradation in humid or salt-laden environments (e.g., naval platforms). |
| MIL-PRF-19500/516 JANTXV qualification | Validates screening, testing, and traceability for mission-critical applications where failure is not acceptable. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6156US | Same electrical specs but supplied in bulk (not tape-and-reel); no TR suffix. | Preferred for manual prototyping or low-volume hand-soldered assemblies. | Select JANTXV1N6156US/TR when automated SMT placement and reel-based logistics are required. |
| 1N6156AUS | Commercial-grade version; same VWM/V(BR)/VC/IPP but unqualified to MIL-PRF-19500/516. | Suitable for non-military industrial systems where cost and RoHS compliance are prioritized over screening. | Choose 1N6156AUS only if JANTXV-level reliability testing and traceability are not mandated. |
Compared with JANTXV1N6156US/TR, JANTXV1N6156US lacks tape-and-reel packaging support for high-speed placement, while 1N6156AUS omits military screening-making JANTXV1N6156US/TR the sole choice for production avionics requiring full MIL-PRF-19500/516 JANTXV traceability and SMT-ready delivery.

FAQ
What is the clamping voltage of JANTXV1N6156US/TR under a 10/1000 µs surge?
JANTXV1N6156US/TR clamps to 53.6 V at 28.0 A under a 10/1000 µs waveform. This value is measured per standard test conditions defined in MIL-PRF-19500/516 and appears in the Electrical Characteristics table on page 3 of the official Microsemi datasheet T4-LDS-0278-1 Rev. 2. The clamping voltage directly limits the maximum stress imposed on downstream circuitry during surge events.
Is JANTXV1N6156US/TR suitable for bidirectional signal line protection?
Yes, JANTXV1N6156US/TR is explicitly designed as a bidirectional TVS with no polarity marking and symmetrical conduction characteristics. Its VWM = 29.7 V and VC = 53.6 V apply equally in both directions, making it appropriate for protecting AC-coupled interfaces such as ARINC 429, MIL-STD-1553, or isolated sensor outputs without orientation constraints.
Does JANTXV1N6156US/TR meet IEC61000-4-2 and IEC61000-4-5 standards?
JANTXV1N6156US/TR provides ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4 respectively, and protects against secondary effects of lightning per select levels in IEC61000-4-5. These capabilities are confirmed in the Applications/Benefits section of the Microsemi datasheet, supported by its 1500 W peak pulse power rating and verified clamping performance at 28.0 A.
What is the thermal resistance of JANTXV1N6156US/TR from junction to end cap?
The thermal resistance from junction to end cap (RθJEC) for JANTXV1N6156US/TR is 5.0 °C/W, as specified in the Maximum Ratings table on page 1 of the Microsemi datasheet. This parameter governs heat transfer efficiency during transient events and informs PCB pad design for optimal thermal relief in high-power surge scenarios.
Can JANTXV1N6156US/TR be used in space applications?
JANTXV1N6156US/TR is inherently radiation hard as described in Microsemi MicroNote 050 and qualified to MIL-PRF-19500/516 JANTXV level, supporting use in space-qualified electronics. Its hermetic glass package, Category 1 metallurgical bonds, and operational range up to +175 °C make it suitable for satellite power interfaces where TID tolerance and thermal stability are critical.
