Product details
Overview
JANTX1N6147US/TR from Microsemi is a military-qualified, voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package. It provides 12.2 V working standoff voltage (VWM), 15.20 V minimum breakdown voltage (V(BR)) at 75 mA, clamps to 22.3 V at 67.3 A peak pulse current (IPP), and delivers 1500 W peak pulse power for 10/1000 µs waveform - used for lightning surge and ESD protection in avionics power interfaces.
For engineers reviewing the JANTX1N6147US/TR datasheet, JANTX1N6147US/TR pinout, JANTX1N6147US/TR application, or JANTX1N6147US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTX qualification, bidirectional clamping behavior, hard-glass robustness, Category 1 metallurgical bonds, and IEC61000-4-2/4-4/4-5 compliance for high-reliability defense systems.
Technical Context
This TVS operates bidirectionally with no polarity marking and relies on avalanche breakdown across both polarities. Its voidless hermetic glass construction ensures long-term stability under thermal cycling and radiation exposure, validated per MIL-STD-750 Method 1020 for ESD immunity.
Thermal resistance junction-to-end cap is 5.0 °C/W, enabling reliable power dissipation up to 5.0 W at TEC = 150 °C with linear derating to zero at 175 °C. The device sustains 0.01% impulse repetition rate and withstands 260 °C solder temperature for 10 s per EIA-481-B tape-and-reel handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.2 V - maximum continuous reverse/forward voltage before clamping begins; sets system operating margin below breakdown. |
| V(BR) min | 15.20 V @ 75 mA - guaranteed avalanche onset threshold; defines minimum overvoltage trip point under test conditions. |
| VC @ IPP | 22.3 V @ 67.3 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum transient stress level. |
| PPP | 1500 W - peak transient energy absorption capability; enables survivability against lightning-induced surges per IEC61000-4-5. |
| ID @ VWM | 20 µA - leakage current at rated standoff; low enough to avoid loading sensitive bias networks in precision analog front-ends. |
| αV(BR) | 0.08 %/°C - temperature coefficient of breakdown voltage; ensures predictable clamping shift over -55 to +175 °C operating range. |
| TJ/TSTG | -55 to +175 °C - qualified junction/storage temperature range; supports deployment in extended-environment military platforms. |
Pinout & Package
Package: SQ-MELF (Square-End-Cap Metal Electrode Leadless Face), hermetically sealed voidless hard glass case with tungsten slugs and tin/lead-plated copper terminals. Weight ≈ 1100 mg. No polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Common terminal pair | Both ends function identically; no DC polarity dependency - simplifies PCB layout and eliminates orientation errors in automated placement. |
| End Cap (both ends) | Current-carrying terminal | Full-surface contact area enables low-inductance surge conduction and efficient heat transfer to PCB pads or heatsinks. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic seal | Prevents moisture ingress and internal corrosion over 20+ year field life in humid or vacuum environments. |
| Category 1 metallurgical bonds | Ensures mechanical integrity under shock/vibration (MIL-STD-883 Method 2002) and thermal cycling (MIL-STD-202 Method 107). |
| Bidirectional clamping | Protects AC-coupled or floating signal lines without requiring dual-device configurations or polarity-aware routing. |
| MIL-PRF-19500/516 JANTX qualification | Validates manufacturing traceability, lot-level testing, and screening per military reliability standards - required for DoD procurement. |
| IEC61000-4-2/4-4/4-5 compliance | Meets Level 4 ESD (±15 kV air), Level 4 EFT (±2 kV), and select lightning surge levels - reduces need for external filtering stages. |
Applications
| Aerospace Power Distribution | Avionics Data Bus Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6146US/TR | 11.4 V VWM, 14.25 V V(BR) min, 21.0 V VC @ 71.4 A - lower clamping voltage but reduced surge margin. | Better suited for 12 V nominal systems with tighter voltage margins; less headroom for aging or temperature drift. | Select when system VCC tolerance is ±5% and clamping headroom must be minimized. |
| JANTX1N6148US/TR | 13.7 V VWM, 17.10 V V(BR) min, 25.1 V VC @ 59.8 A - higher standoff but elevated clamping voltage. | Preferred for 15 V rail protection where higher VWM prevents false triggering during normal transients. | Choose when protecting circuits with >13.5 V operating range and where 25.1 V clamping is acceptable. |
Compared with JANTX1N6147US/TR, JANTX1N6146US/TR offers tighter clamping at lower voltage but sacrifices surge current capacity, while JANTX1N6148US/TR extends standoff range at the cost of higher clamping - making JANTX1N6147US/TR the balanced choice for standard 12 V military subsystems.

FAQ
What is the clamping voltage of JANTX1N6147US/TR under a 10/1000 µs surge?
The JANTX1N6147US/TR clamps to a maximum of 22.3 V when subjected to its rated 67.3 A peak pulse current (IPP) under the standardized 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and reflects worst-case device behavior across temperature and process variation - critical for verifying that downstream ICs remain within absolute maximum ratings during surge events.
Is JANTX1N6147US/TR RoHS compliant?
No, JANTX1N6147US/TR is not RoHS compliant. Per the nomenclature table in Microsemi's T4-LDS-0278-1 datasheet, the "e3" RoHS suffix is only available on commercial-grade versions; JANTX-level parts like JANTX1N6147US/TR use traditional tin/lead plating to meet MIL-PRF-19500/516 solderability and reliability requirements.
Does JANTX1N6147US/TR have polarity markings?
No, JANTX1N6147US/TR has no polarity marking because it is a bidirectional TVS. Both terminals are functionally identical, and the device clamps symmetrically for positive and negative transients - eliminating orientation constraints during automated placement and reducing assembly error risk in high-mix military PCB assembly.
What is the maximum steady-state power dissipation for JANTX1N6147US/TR at 25 °C ambient?
JANTX1N6147US/TR has a maximum steady-state power dissipation of 3.0 W at TA = 25 °C, as specified in the "Off-State Power @ TA = 25 °C" parameter. This rating assumes adequate PCB copper area and thermal vias to maintain junction temperature within limits - exceeding this value risks thermal runaway during sustained overvoltage conditions.
How does JANTX1N6147US/TR differ from commercial-grade 1N6147AUS?
JANTX1N6147US/TR differs from commercial 1N6147AUS in qualification level, screening, and packaging: it is fully screened to MIL-PRF-19500/516 JANTX requirements (including burn-in, temperature cycling, and lot acceptance testing), uses non-RoHS tin/lead terminations, and carries full traceability documentation - whereas 1N6147AUS is commercial-grade with optional RoHS compliance and no military screening.
