Product details
Overview
JANTX1N6150AUS/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), 16.7 V working standoff voltage (VWM), and 30.5 V clamping voltage (VC) at 49.2 A peak pulse current - deployed in avionics power rail protection and radar front-end surge suppression.
For engineers reviewing the JANTX1N6150AUS/TR datasheet, JANTX1N6150AUS/TR pinout, JANTX1N6150AUS/TR application, or JANTX1N6150AUS/TR equivalent, key selection criteria include MIL-PRF-19500/516 qualification level (JANTX), bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W junction-to-end cap), and compatibility with high-reliability PCB assembly requiring 260 °C solder tolerance.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds for radiation-hardened reliability per MicroNote 050. Its hard-glass construction enables stable performance across –55 °C to +175 °C junction temperature range and supports ESD immunity per MIL-STD-750 Method 1020.
The device delivers 1500 W peak pulse power under 10/1000 µs waveform while maintaining 5 µA maximum standby current at VWM, and exhibits 0.085 %/°C temperature coefficient of breakdown voltage - critical for precision overtemperature clamping in aerospace power conditioning circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - sustains single high-energy transients without failure in lightning-induced surge events |
| Working Standoff Voltage (VWM) | 16.7 V - maximum continuous DC or repetitive peak voltage before conduction begins |
| Clamping Voltage (VC @ IPP) | 30.5 V at 49.2 A - limits downstream circuit voltage during transient to safe margin above VWM |
| Breakdown Voltage (VBR) | 20.9 V @ 50 mA - precise threshold where avalanche conduction initiates under controlled test current |
| Junction Temperature Range | –55 °C to +175 °C - supports operation in extended-environment military platforms including engine bays and space-qualified enclosures |
| Thermal Resistance (RθJEC) | 5.0 °C/W - enables efficient heat transfer from junction to end cap, critical for pulsed-power derating above 150 °C |
| ESD Rating | IEC61000-4-2 compliant - withstands ±8 kV contact discharge without parametric shift or functional failure |
Pinout & Package
SQ-MELF (Square-End-Cap Metal Electrode Leadless Face) hermetically sealed voidless glass package with tungsten slugs and tin/lead-plated copper terminals; weight ≈ 1100 mg; dimensions: BD = 4.65–5.13 mm, BL = 5.21–6.22 mm, ECT = 0.48–0.71 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | No polarity marking - symmetric terminals conduct equally in either direction during overvoltage events |
| End Cap (both ends) | Thermal interface & mechanical anchor | Directly transfers heat to PCB pads; requires full-surface solder wetting for RθJEC compliance |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Eliminates moisture ingress and internal delamination risk in 100% humidity or vacuum environments |
| Category 1 metallurgical bonds | Enables >100 krad(Si) total ionizing dose tolerance and survivability in radiation-intensive missions |
| MIL-PRF-19500/516 JANTX qualification | Validated screening includes burn-in, temperature cycling, and lot acceptance testing per military standard |
| Triple-layer passivation | Prevents surface leakage and parameter drift under high-humidity, salt-fog, or condensation exposure |
| Square-end-cap geometry | Ensures consistent placement accuracy and solder joint integrity on automated SMT lines |
Applications
| Avionics Power Distribution | Radar RF Front-End 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 |
|---|---|---|---|
| 1N6150US (commercial grade) | No MIL-PRF-19500/516 qualification; same electrical specs but no JANTX screening or radiation hardening | Limited to non-mission-critical industrial controls; not approved for flight hardware or spaceflight use | Select only when cost sensitivity outweighs reliability requirements and environmental stress testing is waived |
| JANTXV1N6150AUS | Higher screening level (JANTXV) includes extended temperature cycling, hermeticity verification, and 100% lot testing | Required for Class S (spaceflight) and Class H (high-reliability avionics) programs per NASA-SSP-30238 | Choose when system-level FMEA mandates zero latent defects and full traceability to wafer lot |
Compared with JANTX1N6150AUS/TR, the commercial 1N6150US reduces procurement lead time and cost but forfeits military-grade screening, while JANTXV1N6150AUS adds process rigor and test coverage essential for zero-failure launch-critical systems - all share identical SQ-MELF footprint and clamping performance.

FAQ
What is the clamping voltage of JANTX1N6150AUS/TR at its rated peak pulse current?
The JANTX1N6150AUS/TR has a maximum clamping voltage (VC) of 30.5 V when subjected to its rated peak pulse current (IPP) of 49.2 A under the standard 10/1000 µs waveform. This value is guaranteed per MIL-PRF-19500/516 test conditions and reflects worst-case conduction behavior during surge events. The JANTX1N6150AUS/TR maintains this clamping performance across its full operating temperature range.
Is JANTX1N6150AUS/TR compatible with lead-free reflow processes?
JANTX1N6150AUS/TR is qualified for solder reflow at 260 °C for 10 seconds, meeting standard lead-free reflow profiles. However, its terminations are tin/lead plated per MIL-PRF-19500/516 requirements, so it is not RoHS-compliant. For RoHS applications, Microsemi offers commercial-grade variants marked with "e3", but those lack JANTX qualification. The JANTX1N6150AUS/TR must be processed in dedicated SnPb lines.
Does JANTX1N6150AUS/TR have polarity markings for PCB layout?
No, JANTX1N6150AUS/TR is a bidirectional TVS and carries no polarity markings on its SQ-MELF glass body. Both terminals are functionally identical, allowing unrestricted orientation during placement. This symmetry simplifies layout and eliminates risk of reverse installation - a key advantage in high-density military PCBs where silkscreen space is constrained.
What is the maximum steady-state power dissipation for JANTX1N6150AUS/TR at 25 °C ambient?
JANTX1N6150AUS/TR has a maximum steady-state power dissipation (PD) of 3.0 W at TA = 25 °C, as specified in the Absolute Maximum Ratings table. This rating assumes adequate PCB thermal management; derating begins linearly above 25 °C ambient and reaches zero at 150 °C case temperature. The JANTX1N6150AUS/TR is not intended for continuous power regulation.
How does JANTX1N6150AUS/TR differ from the non-"A" version (e.g., JANTX1N6150US)?
The "A" suffix in JANTX1N6150AUS/TR denotes tighter voltage tolerances: minimum breakdown voltage is 20.9 V (vs. 5% lower for non-A), clamping voltage is 30.5 V (vs. 5% higher for non-A), and peak pulse current is 49.2 A (vs. 5% lower for non-A). These tighter specs ensure more predictable clamping margins in safety-critical designs. The JANTX1N6150AUS/TR also includes full JANTX screening not present in the base-number variant.
