Product details
Overview
JANTXV1N6151US/TR from Microsemi is a military-qualified, voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF (C) package. It provides 18.2 V working standoff voltage (VWM), 22.8 V minimum breakdown voltage (V(BR)), 33.3 V clamping voltage (VC) at 45.0 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform-designed for lightning surge and ESD protection in avionics power interfaces.
For engineers reviewing the JANTXV1N6151US/TR datasheet, JANTXV1N6151US/TR pinout, JANTXV1N6151US/TR application, or JANTXV1N6151US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTXV qualification, bidirectional clamping behavior, glass-body thermal resistance (RθJEC = 5.0 °C/W), and IEC61000-4-2/4-4/4-5 compliance for high-reliability defense systems.
Technical Context
This device operates as a bidirectional voltage-clamping protector with no polarity marking, relying on symmetrical avalanche breakdown in both directions. Its hard-glass construction uses internal Category 1 metallurgical bonds and triple-layer passivation to ensure robustness under repeated 10/1000 µs transients up to 1500 W.
It is rated for junction temperatures from –55 °C to +175 °C and features linear derating of off-state power above 150 °C at the end cap. The 5.0 °C/W junction-to-end-cap thermal resistance enables direct thermal coupling to heatsinking pads without PCB vias, supporting stable operation in conduction-cooled military chassis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 18.2 V - Maximum continuous reverse/forward voltage before clamping begins; sets system operating margin below breakdown. |
| V(BR) min | 22.8 V @ 50 mA - Confirmed avalanche onset threshold; ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 33.3 V @ 45.0 A - Clamped voltage during 10/1000 µs surge; defines worst-case stress on downstream ICs. |
| PPP | 1500 W - Peak transient energy handling capacity; supports Level 4 IEC61000-4-5 (4 kV line-earth) protection. |
| TJ Range | –55 °C to +175 °C - Full military temperature range; validated for operation in sealed avionics enclosures. |
| RθJEC | 5.0 °C/W - Low thermal resistance to end cap; allows direct mounting to metal chassis for passive cooling. |
| IEC Compliance | IEC61000-4-2 (ESD), -4-4 (EFT), -4-5 (surge) - Certified test performance; no additional external filtering required. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6151AUS | Commercial-grade version; same VWM (18.2 V), VC (33.3 V), and IPP (45.0 A), but not MIL-qualified. | Lacks JANTXV screening, burn-in, and lot traceability; unsuitable for flight or mission-critical hardware. | Select only for ground-test fixtures or non-safety-critical prototypes where cost outweighs reliability assurance. |
| JANTXV1N6150US/TR | Lower VWM (16.7 V), V(BR) min (20.9 V), and VC (30.5 V); 49.2 A IPP; otherwise identical package and qualification. | Better suited for 24 V nominal systems requiring tighter clamping margin; trades higher surge current for lower voltage headroom. | Choose when protecting 24 V logic rails where 30.5 V clamping is acceptable and 49.2 A surge margin is preferred over 18.2 V standoff. |
Compared with JANTXV1N6151US/TR, 1N6151AUS offers identical electrical specs but no military screening, while JANTXV1N6150US/TR delivers lower clamping voltage at reduced standoff-enabling tighter protection windows in 24 V systems without changing board layout or thermal design.

FAQ
What is the maximum clamping voltage of JANTXV1N6151US/TR under a 10/1000 µs surge?
The JANTXV1N6151US/TR has a maximum clamping voltage (VC) of 33.3 V when subjected to its rated peak pulse current of 45.0 A under a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and is guaranteed across the full –55 °C to +175 °C junction temperature range. The JANTXV1N6151US/TR maintains this clamping performance without degradation after multiple surge events due to its voidless hermetic construction.
Is JANTXV1N6151US/TR compatible with lead-free reflow processes?
JANTXV1N6151US/TR is qualified for solder reflow at 260 °C for 10 seconds per MIL-STD-750 Method 2032, making it compatible with standard lead-free reflow profiles. Its tin/lead-plated terminals are designed for SnPb solder, but the glass body and internal structure withstand lead-free thermal excursions. For RoHS compliance, commercial-grade 1N6151AUS (e3 marked) is available-but JANTXV1N6151US/TR itself is not RoHS-compliant.
Does JANTXV1N6151US/TR require polarity-aware PCB layout?
No-JANTXV1N6151US/TR is a bidirectional TVS with no polarity marking and symmetrical electrical characteristics in both directions. Its SQ-MELF package has identical terminals, allowing orientation-agnostic placement on PCBs. This eliminates assembly errors and simplifies layout for differential or AC-coupled lines, unlike unidirectional TVS devices that mandate strict anode/cathode routing.
How does JANTXV1N6151US/TR perform under repeated surge stress?
JANTXV1N6151US/TR is screened for surge endurance per MIL-PRF-19500/516, with demonstrated stability across ≥1000 repetitive 10/1000 µs pulses at 50% of rated PPP (750 W). Its Category 1 metallurgical bonds and triple-layer passivation prevent parameter drift or catastrophic failure. Data shows <5% variation in VC after 500 cycles at full 1500 W rating-validating suitability for systems with frequent lightning exposure.
What thermal interface method is recommended for JANTXV1N6151US/TR in high-power surge conditions?
For optimal thermal performance, JANTXV1N6151US/TR should be mounted with its end cap directly contacting a thermally conductive surface (e.g., aluminum chassis or copper pour) using thermally conductive adhesive or solder. Its RθJEC of 5.0 °C/W enables effective heat extraction without vias; pad layout must follow Microsemi's recommended footprint with optional 0.090-inch center adhesive spot per datasheet Page 7.
