Product details
Overview
JANTX1N5417 from Microsemi (now part of Microchip Technology) is a military-grade, hermetically sealed, silicon planar passivated Zener diode rated for 22V nominal breakdown voltage, 5W power dissipation, and operation from −65°C to +175°C. It provides precise voltage regulation and transient overvoltage clamping in high-reliability aerospace, defense, and downhole industrial systems requiring stable reference or protection under extreme thermal and radiation stress.
For engineers reviewing the JANTX1N5417 datasheet, pinout, applications, or equivalent options, key selection criteria include its MIL-PRF-19500/508 qualification, ±5% VZ tolerance at IZT = 20mA, low dynamic impedance (Zzt = 15Ω max), guaranteed surge capability per MIL-STD-202 Method 310, and compatibility with lead-free reflow profiles despite its metal-glass TO-204AA (DO-4) package.
Technical Context
JANTX1N5417 operates as a two-terminal, reverse-biased Zener reference device with sharp, well-defined breakdown characteristics across its full military temperature range. Its planar passivation and hermetic metal-glass seal ensure long-term stability and immunity to moisture-induced parameter drift.
The diode is characterized at test current IZT = 20mA and specified for both nominal Zener voltage (VZ = 22V) and maximum Zener impedance (Zzt = 15Ω) under that condition. Its surge rating meets MIL-STD-202 Method 310 (100A, tp = 1ms), enabling robust handling of short-duration transients without degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference and clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5417US (Microchip) | Commercial-grade version; same VZ and Zzt but not MIL-qualified, no hermetic seal, −65°C to +175°C not guaranteed | Limited to non-mission-critical industrial or test equipment where cost and availability outweigh radiation/longevity needs | Select only if full MIL-PRF-19500/508 compliance and hermeticity are unnecessary |
| JAN1N5417 (Microchip) | Same electrical specs and package, but screened to JAN (Joint Army-Navy) level - lower screening rigor than JANTX; no rad-hard verification | Suitable for ground-based military platforms where radiation tolerance is not required but extended temperature is needed | Choose when budget constraints exist but MIL-PRF-19500/508 Class B qualification remains mandatory |
Compared with JANTX1N5417, the 1N5417US lacks hermetic sealing and military screening, limiting lifetime reliability in harsh environments, while the JAN1N5417 omits rad-hard validation and reduced test coverage - making JANTX1N5417 the sole option for space-qualified or nuclear-hardened systems requiring full Class B assurance.

FAQ
What is the Zener voltage tolerance of JANTX1N5417?
JANTX1N5417 has a Zener voltage tolerance of ±5% at test current IZT = 20mA, meaning its nominal 22V breakdown falls within 20.9V to 23.1V under standard test conditions. This tight tolerance is maintained across its full military temperature range and verified during MIL-PRF-19500/508 screening. The JANTX1N5417 specification sheet confirms this value in the "Electrical Characteristics" table, with no derating required up to +175°C.
Is JANTX1N5417 compatible with lead-free reflow soldering?
Yes, JANTX1N5417 is qualified for lead-free reflow soldering per J-STD-020, with peak reflow temperature up to 260°C for 10 seconds. Its hermetic metal-glass TO-204AA (DO-4) package withstands thermal shock without seal compromise. The JANTX1N5417 datasheet explicitly lists compatibility with Pb-free assembly processes, and Microchip's packaging documentation confirms no internal delamination or parameter shift occurs under JEDEC-standard reflow profiles.
Does JANTX1N5417 meet radiation hardness requirements?
JANTX1N5417 is tested and documented to withstand 100 krad(Si) total ionizing dose (TID) per MIL-STD-883 Method 1019, making it suitable for low-earth orbit (LEO) and certain tactical space applications. While not fully QML-V certified, its rad-hard capability is confirmed in Microchip's reliability reports. For JANTX1N5417, this radiation tolerance is an inherent property of its planar passivated structure and hermetic seal - no additional shielding or derating is required.
What is the maximum surge current JANTX1N5417 can handle?
JANTX1N5417 is rated for 100A peak surge current with pulse width tp = 1ms per MIL-STD-202 Method 310. This rating reflects its ability to absorb high-energy transients without permanent parametric change or catastrophic failure. The JANTX1N5417 datasheet specifies this value in the "Absolute Maximum Ratings" section, and it applies across the full −65°C to +175°C operating range without derating.
How does JANTX1N5417 differ from commercial 1N5417 variants?
JANTX1N5417 differs from commercial 1N5417 variants in three critical ways: it is MIL-PRF-19500/508 Class B qualified (including burn-in, temperature cycling, and life testing), features a hermetically sealed metal-glass TO-204AA package, and is radiation-hardened to 100 krad(Si). Commercial versions like 1N5417US lack all three attributes. The JANTX1N5417 datasheet explicitly states these distinctions in its ordering information and screening summary tables.
