Product details
Overview
JANTX1N6143US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package, with 8.4 V working standoff voltage (VWM), 10.45 V minimum breakdown voltage (V(BR)), and 15.6 V clamping voltage (VC) at 96.2 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in avionics power rail protection.
For engineers reviewing the JANTX1N6143US/TR datasheet, JANTX1N6143US/TR pinout, JANTX1N6143US/TR application, or JANTX1N6143US/TR equivalent, key selection criteria include MIL-PRF-19500/516 qualification level (JANTX), bidirectional surge capability, glass-body thermal resistance (5.0 °C/W), and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced transients.
Technical Context
This TVS operates bidirectionally without polarity marking and uses internal Category 1 metallurgical bonds within a hard-glass, voidless hermetic seal to ensure radiation hardness and reliability under extreme thermal cycling (-55 °C to +175 °C). Its 1500 W peak pulse power rating applies specifically to the 10/1000 µs waveform at 25 °C.
The device exhibits low standby current (20 µA at 8.4 V), a temperature coefficient of breakdown voltage of 0.07 %/°C, and linear derating of off-state power above 150 °C junction temperature - enabling stable operation in high-reliability embedded power interfaces where failure is not tolerable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.4 V - maximum continuous reverse/forward voltage before conduction begins; sets operating margin below clamping threshold. |
| V(BR) min | 10.45 V @ 125 mA - guaranteed breakdown onset; ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 15.6 V @ 96.2 A - clamped voltage during 10/1000 µs surge; defines worst-case stress on downstream circuitry. |
| PPP | 1500 W - peak transient energy handling capacity; supports MIL-STD-461/DO-160 lightning surge levels. |
| TJ range | -55 °C to +175 °C - extended operational envelope for aerospace and defense electronics. |
| RθJEC | 5.0 °C/W - junction-to-end-cap thermal resistance; enables direct heatsinking via end-cap mounting. |
| ID @ VWM | 20 µA - leakage current at rated standoff; minimizes quiescent power loss in battery-backed systems. |
Pinout & Package
SQ-MELF (Square End-Cap Metal Electrode Leadless Face) package: hermetically sealed voidless hard glass body with tungsten slugs and tin/lead-plated copper terminals; no polarity marking; weight ≈ 1100 mg; dimensions per Microsemi T4-LDS-0278-1 Rev. 2 (BD: 0.183–0.202", BL: 0.205–0.245").

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6143US/TR | Commercial-grade version; same electrical specs but not MIL-PRF-19500/516 qualified; RoHS-compliant matte-tin plating optional. | Lacks JANTX reliability screening; unsuitable for Class H or space-qualified designs requiring traceable lot testing. | Select only for non-military industrial controls where cost and RoHS compliance outweigh radiation hardness needs. |
| JANTXV1N6143US/TR | Higher reliability screening (JANTXV level); tighter parameter verification; enhanced burn-in and life test protocols per MIL-PRF-19500/516. | Required for flight-critical subsystems (e.g., F-35 EW suite) where single-point failure must be excluded. | Choose when full JANTXV qualification documentation (test reports, lot traceability) is mandated by program spec. |
Compared with JANTX1N6143US/TR, the commercial 1N6143US/TR reduces procurement cost and supports RoHS compliance but forfeits military screening; the JANTXV variant adds qualification rigor for safety-critical deployments but increases lead time and unit cost - selection depends strictly on program-level reliability and audit requirements.

FAQ
What is the clamping voltage of JANTX1N6143US/TR at its rated peak pulse current?
The JANTX1N6143US/TR has a maximum clamping voltage (VC) of 15.6 V at 96.2 A peak pulse current (IPP) for a 10/1000 µs waveform, as specified in Microsemi's T4-LDS-0278-1 Rev. 2 datasheet. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured under standardized impulse conditions. The JANTX1N6143US/TR maintains this clamping performance across its full operating temperature range when properly mounted with adequate thermal path.
Is JANTX1N6143US/TR suitable for bidirectional signal line protection?
Yes, JANTX1N6143US/TR is inherently bidirectional due to its symmetrical avalanche structure and absence of polarity marking - making it appropriate for protecting AC-coupled or floating differential pairs such as MIL-STD-1553B, RS-485, or CAN FD buses. Its 8.4 V working standoff voltage provides headroom for typical signal swing amplitudes while ensuring fast conduction during both positive and negative transients. The JANTX1N6143US/TR achieves this without external biasing or dual-device configurations.
What is the maximum steady-state power dissipation of JANTX1N6143US/TR at 25 °C ambient?
The JANTX1N6143US/TR has a maximum off-state power dissipation (PD) of 3.0 W at TA = 25 °C, as defined in the "Maximum Ratings" table of its datasheet. This rating assumes controlled thermal resistance from mounting point to ambient - typically achieved using copper pour and thermal vias under end-cap terminals. At elevated ambient temperatures, power must be linearly derated per Figure 4, reaching zero at 150 °C end-cap temperature. The JANTX1N6143US/TR does not require active cooling for most 28 V system applications.
Does JANTX1N6143US/TR comply with IEC61000-4-5 for lightning surge immunity?
Yes, JANTX1N6143US/TR provides protection against secondary effects of lightning per select levels of IEC61000-4-5, as confirmed in the "Applications / Benefits" section of Microsemi's T4-LDS-0278-1 datasheet. Its 1500 W peak pulse power rating and 15.6 V clamping voltage enable it to suppress 1 kV line-to-earth surges in combination with appropriate series impedance. The JANTX1N6143US/TR is routinely deployed in DO-160 Section 22 Level 3 and MIL-STD-461G CS115 compliant designs when used with matched source impedance.
What is the temperature coefficient of breakdown voltage for JANTX1N6143US/TR?
The temperature coefficient of breakdown voltage (αV(BR)) for JANTX1N6143US/TR is +0.07 %/°C, meaning its breakdown voltage increases by 0.07% per degree Celsius rise in junction temperature. This value is specified in the Electrical Characteristics table and reflects the positive TC inherent to silicon avalanche structures. For precision voltage reference applications, this drift must be accounted for in thermal design - but for transient suppression, the JANTX1N6143US/TR remains effective across its full -55 °C to +175 °C operating range.
