Overview
JANTXV1N6147US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package, rated for 1500 W peak pulse power (10/1000 µs), 12.2 V working standoff voltage (VWM), and 22.3 V clamping voltage (VC) at 67.3 A peak pulse current. It operates across –55 °C to +175 °C and is used in avionics power rail protection where failure tolerance and radiation hardness are mandatory.
For engineers reviewing the JANTXV1N6147US/TR datasheet, JANTXV1N6147US/TR pinout, JANTXV1N6147US/TR application, or JANTXV1N6147US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTXV qualification, Category 1 metallurgical bonds, triple-layer passivation, voidless glass construction, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning surge immunity.
Technical Context
This device functions as a bidirectional clamping TVS diode with no polarity marking, designed for symmetric transient suppression on AC lines or unidirectional rails without DC bias constraints. Its hard-glass SQ-MELF package enables high thermal reliability via tungsten slugs and direct junction-to-end-cap thermal path (RθJEC = 5.0 °C/W).
It delivers 1500 W peak pulse power under standardized 10/1000 µs waveform conditions, with breakdown voltage V(BR) = 15.20 V @ 75 mA and temperature coefficient αV(BR) = 0.08 %/°C - enabling predictable clamping behavior across extended military temperature ranges.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6147US/TR | Commercial-grade version; same electrical specs but lacks JANTXV screening, burn-in, and MIL-PRF-19500/516 qualification. | Not approved for flight-critical or nuclear-safety systems; limited to ground-test or non-mission-critical prototypes. | Select only when full military reliability testing is unnecessary and cost sensitivity outweighs long-term field assurance. |
| JANTXV1N6146US/TR | Lower VWM (11.4 V) and VC (21.0 V); 71.4 A IPP; identical package and qualification level. | Better suited for 12 V nominal systems with tighter clamping margin; may trigger prematurely in 28 V bus applications. | Choose when system operating voltage is ≤12 V and lower clamping voltage is prioritized over higher surge energy margin. |
Compared with JANTXV1N6147US/TR, the commercial 1N6147US/TR sacrifices qualification rigor for cost, while JANTXV1N6146US/TR trades standoff margin for tighter clamping - making JANTXV1N6147US/TR optimal for 24–28 V military platforms requiring both robustness and precise voltage coordination.

FAQ
What is the clamping voltage of JANTXV1N6147US/TR under a 10/1000 µs surge?
The JANTXV1N6147US/TR has a maximum clamping voltage (VC) of 22.3 V when subjected to its rated peak pulse current of 67.3 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 JANTXV1N6147US/TR maintains this clamping performance across its full operating temperature range.
Is JANTXV1N6147US/TR RoHS compliant?
No, JANTXV1N6147US/TR is not RoHS compliant. Per the nomenclature table in Microsemi's T4-LDS-0278-1 datasheet, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants (e.g., 1N6147AUS). The JANTXV prefix indicates military qualification under MIL-PRF-19500/516, which retains leaded terminations for enhanced solder joint reliability and thermal fatigue resistance.
What does the "US" suffix indicate in JANTXV1N6147US/TR?
The "US" suffix in JANTXV1N6147US/TR denotes the SQ-MELF surface-mount package configuration - specifically, a voidless hermetically sealed hard-glass case with square end caps and tungsten slugs. This distinguishes it from axial-leaded versions (e.g., 1N6147) and confirms compatibility with automated SMT placement and reflow processes per EIA-481-B tape-and-reel standards.
How does JANTXV1N6147US/TR achieve radiation hardness?
JANTXV1N6147US/TR achieves inherent radiation hardness through its hard-glass hermetic construction and silicon die design, as documented in Microsemi MicroNote 050. The absence of organic passivation layers and use of Category 1 metallurgical bonds prevent displacement damage and charge trapping under total ionizing dose (TID) exposure. This enables reliable operation in space and nuclear environments without derating.
Can JANTXV1N6147US/TR be used in bidirectional AC line protection?
Yes, JANTXV1N6147US/TR is explicitly designed as a bidirectional TVS with no polarity marking, making it suitable for symmetric AC line protection such as telecom ringers, transformer-coupled interfaces, or isolated sensor inputs. Its 12.2 V VWM and 22.3 V VC provide defined clamping margins for ±12 V nominal AC signals, and its 1500 W rating handles repetitive surge events without degradation.
