Product details
Overview
JANTX1N6165US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTX reliability level. It provides 69.2 V working peak standoff voltage (VWM), 125.1 V clamping voltage (VC) at 12 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in avionics power bus protection and radar front-end surge suppression.
For engineers reviewing the JANTX1N6165US/TR datasheet, JANTX1N6165US/TR pinout, JANTX1N6165US/TR application, or JANTX1N6165US/TR equivalent, key selection criteria include its military-grade hermetic glass package, Category 1 metallurgical bonds, -55°C to +175°C junction temperature range, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced surge immunity.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses hard-glass construction with tungsten slugs for thermal stability. Its breakdown voltage is 86.5 V minimum at 15 mA test current, and it exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.100 %/°C - critical for high-temperature military platforms where voltage drift must remain bounded.
The device delivers 1500 W peak pulse power under standardized 10/1000 µs transient conditions while maintaining clamping performance across its full operating temperature range. Thermal resistance from junction to end cap is 5.0 °C/W, enabling reliable power dissipation in constrained surface-mount layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 69.2 V - maximum continuous reverse standoff voltage before conduction begins; sets system-level overvoltage trip threshold. |
| V(BR) min | 86.5 V @ 15 mA - guaranteed minimum breakdown voltage; defines lower bound of clamping onset region. |
| VC @ IPP | 125.1 V @ 12 A - clamping voltage during 10/1000 µs surge; determines maximum voltage seen by protected ICs. |
| PPP | 1500 W - peak pulse power rating; supports robust protection against lightning secondary effects per IEC61000-4-5. |
| TJ Range | -55°C to +175°C - extended junction temperature range enables deployment in engine bay, radar, and space-qualified systems. |
| RθJEC | 5.0 °C/W - low thermal resistance to end cap allows direct heat transfer to PCB copper or chassis mounting points. |
| ID @ VWM | 5 µA - ultra-low leakage current ensures minimal standby power loss in always-on military subsystems. |
Pinout & Package
Package: SQ-MELF (C package), hermetically sealed voidless hard glass with tungsten slugs; tin/lead-plated copper terminals; no polarity marking; weight ≈1100 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | Both terminals function identically; no DC polarity - enables symmetric placement across differential lines or unidirectional rails. |
| End Cap (glass body contact) | Thermal interface | Direct thermal path to PCB copper pour or metal chassis; requires soldered end-cap contact for rated RθJEC = 5.0 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Eliminates internal moisture ingress and long-term parameter drift - essential for 20+ year field life in sealed avionics enclosures. |
| Category 1 metallurgical bonds | Guarantees bond integrity under mechanical shock, thermal cycling, and radiation exposure per MIL-PRF-19500/516. |
| Triple-layer passivation | Prevents surface leakage and corrosion on glass-to-metal interfaces in high-humidity or salt fog environments. |
| IEC61000-4-5 compliance | Validated protection against lightning-induced surges up to select levels - reduces need for external filtering in ground vehicle comms systems. |
Applications
| Aerospace Power Distribution | Ground Vehicle Radar Front-End |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6165AUS | Commercial-grade version; same VWM (69.2 V), VC (125.1 V), and PPP (1500 W), but not MIL-qualified. | Lacks JAN/JANTX qualification; unsuitable for DoD procurement or flight-critical systems. | Select only for non-military industrial prototypes or cost-sensitive commercial variants requiring identical electrical specs. |
| JANTXV1N6165US | Higher reliability grade (JANTXV); same electrical specs but qualified to tighter parametric limits and extended screening per MIL-PRF-19500/516. | Required for space-qualified payloads and nuclear-hardened systems where failure rate must be <10⁻⁶/hr. | Choose when mission-critical uptime, radiation hardness per MicroNote 050, or extended temperature cycling validation is mandatory. |
Compared with JANTX1N6165US/TR, 1N6165AUS offers identical clamping performance at lower cost but no military traceability, while JANTXV1N6165US adds screening rigor and radiation tolerance - making the JANTX variant the optimal balance of qualification assurance and production scalability for defense prime integrators.

FAQ
What is the clamping voltage of JANTX1N6165US/TR under standard 10/1000 µs surge conditions?
The JANTX1N6165US/TR has a maximum clamping voltage (VC) of 125.1 V at 12 A peak pulse current (IPP) for a 10/1000 µs waveform. This value is measured per MIL-PRF-19500/516 test methods and represents the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is JANTX1N6165US/TR RoHS compliant?
No, JANTX1N6165US/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant matte-tin terminations are available only on commercial-grade versions (e.g., 1N6165AUS), not on JAN, JANTX, JANTXV, or JANS qualified parts. The JANTX1N6165US/TR uses traditional tin/lead plating to ensure solder joint reliability under thermal cycling and mechanical shock per military standards.
What does the "US" suffix indicate in JANTX1N6165US/TR?
The "US" suffix in JANTX1N6165US/TR denotes the SQ-MELF surface-mount package configuration - specifically the hermetically sealed voidless hard-glass case with square-end-cap terminals. It distinguishes this variant from axial-leaded versions (e.g., 1N6165) and confirms compatibility with automated SMT placement and reflow processes per EIA-481-B tape-and-reel standards.
How does JANTX1N6165US/TR differ from the non-"A" version (e.g., JANTX1N6165US)?
JANTX1N6165US/TR is the "A" version, meaning it meets tighter voltage tolerances: minimum breakdown voltage is 86.5 V (vs. 5% lower for non-A), clamping voltage is 125.1 V (vs. 5% higher for non-A), and peak pulse current is 12 A (vs. 5% lower for non-A). These tighter specs ensure more predictable clamping behavior in precision military systems where margin control is critical.
Can JANTX1N6165US/TR be used in place of JANTXV1N6165US in a design?
JANTX1N6165US/TR may be used in place of JANTXV1N6165US only if the application does not require JANTXV-level screening - including extended burn-in, radiation testing per MIL-STD-883, and tighter parametric limits. Electrically, both share identical VWM, VC, and PPP; however, JANTXV qualification adds validation for space and nuclear environments where single-event effects must be mitigated.
