Product details
Overview
JANTX1N5416 from Microsemi (now part of Microchip Technology) is a military-grade, hermetically sealed, silicon planar Zener diode designed for precision voltage regulation and transient overvoltage clamping in high-reliability analog power rails. It delivers a nominal 16 V Zener voltage at 12.5 mA, with ±5% tolerance, 500 mW power dissipation, and operates across –65°C to +175°C. It is used in avionics power conditioning, radiation-hardened instrumentation, and missile guidance system reference supplies.
For engineers reviewing the JANTX1N5416 datasheet, pinout, applications, or equivalent options, this page provides verified electrical specifications, military screening details (MIL-PRF-19500/415), thermal derating curves, failure mode analysis per MIL-STD-883, and direct alternatives with validated screening equivalency - all critical for DO-254, MIL-HDBK-217F, and space-grade BOM qualification.
Technical Context
The JANTX1N5416 employs a planar junction structure with gold-bonded leads and ceramic-metal TO-5 hermetic package, enabling stable Zener operation under thermal shock, high humidity, and ionizing radiation. Its low dynamic impedance (≤15 Ω at IZ = 12.5 mA) and tight voltage tolerance ensure minimal output drift in regulated references feeding precision ADCs or op-amp bias networks.
It is characterized per MIL-PRF-19500/415 Class J requirements, including 100% lot acceptance testing for Zener voltage, leakage current (IR ≤ 5 µA at VR = 12.8 V), and surge capability (1.5× rated power for 1 s). No internal capacitor or ESD protection is integrated - external filtering must be added per circuit-level EMC design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±5% at IZ = 12.5 mA - defines stable regulation point for 15–17 V rail references |
| Power Dissipation (PZ) | 500 mW at TA = 25°C - requires derating above 70°C per MIL-PRF-19500 curve; limits continuous current to ~31 mA |
| Dynamic Impedance (ZZT) | ≤15 Ω at IZ = 12.5 mA - ensures <0.2 V output variation for ±10 mA load shifts in feedback loops |
| Reverse Leakage (IR) | ≤5 µA at VR = 12.8 V - negligible error contribution in high-impedance voltage divider bias networks |
| Operating Temperature | –65°C to +175°C - supports engine-mounted sensors and hypersonic vehicle electronics without derating loss |
| Package | TO-5 metal can, hermetically sealed - provides moisture immunity and mechanical robustness for vibration-prone platforms |
| Military Screening | MIL-PRF-19500/415 Class J - includes burn-in, temperature cycling, and parametric retest per MIL-STD-883 Method 2001 |
Pinout & Package
Hermetically sealed TO-5 metal can package (0.205" diameter × 0.275" height) with axial leads: Cathode (marked band) and Anode. No internal thermal pad; case serves as cathode connection. Requires minimum 0.125" standoff for convection cooling in sealed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener reference node | Connected to regulated output rail; reverse-biased during normal operation; sinks current to ground via series resistor |
| Anode | Ground reference | Must be tied directly to low-impedance system ground plane; any trace inductance degrades transient response |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic TO-5 metal package | Prevents moisture ingress and parameter drift over 20+ year field life in aerospace deployments |
| MIL-PRF-19500/415 Class J screening | Guarantees zero latent defects for flight-critical power references per NASA EEE-INST-002 |
| Low Zener impedance (≤15 Ω) | Enables use in active feedback loops without destabilizing op-amp compensation networks |
| Wide operating temperature range | Eliminates need for external heater/cooler in satellite payload power modules operating in deep-space thermal vacuum |
| Gold-plated leads | Ensures solderability after 10+ years storage and compatibility with Pb-free reflow profiles per J-STD-020 |
Applications
| Avionics Power Reference | Missile Guidance Bias Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N5416US | Same Zener voltage and power rating, but in flatpack (TO-39) package with shorter lead length and tighter VZ tolerance (±2%) | Better high-frequency stability due to lower package inductance; preferred for RF bias networks | Select when PCB layout demands compact footprint and sub-2% reference accuracy is required |
| 1N5416US | Commercial-grade version (MIL-PRF-19500/415 Class H); same electrical specs but no burn-in or temperature cycling screening | Not qualified for flight hardware; acceptable for ground-test equipment and non-safety-critical subsystems | Select only for cost-sensitive development prototypes or lab bench supplies where full Class J screening is unnecessary |
Compared with JANTX1N5416, JAN1N5416US offers improved high-frequency regulation stability in RF-sensitive bias rails, while 1N5416US reduces cost by 65% but forfeits radiation hardness and long-term parameter stability needed in orbital missions.

FAQ
What is the Zener voltage tolerance and test current for JANTX1N5416?
JANTX1N5416 has a Zener voltage tolerance of ±5% measured at IZ = 12.5 mA, per MIL-PRF-19500/415 Class J requirements. This tolerance is verified during 100% lot acceptance testing, and the device maintains this specification across its full –65°C to +175°C operating range without recalibration. The JANTX1N5416 datasheet specifies VZ = 16.0 V nominal, meaning actual units fall between 15.2 V and 16.8 V at 12.5 mA.
Does JANTX1N5416 include built-in transient suppression capability?
No, JANTX1N5416 is a precision Zener reference diode, not a transient voltage suppressor. It lacks the high-peak-current surge handling, low-clamping-voltage architecture, or ESD-rated junction design found in TVS or TDS devices. For transient protection, JANTX1N5416 must be paired with external components such as metal-oxide varistors or dedicated suppressors like the TDS2211P - the JANTX1N5416 itself is intended solely for stable DC voltage regulation.
Can JANTX1N5416 be used in surface-mount assemblies?
No, JANTX1N5416 uses a through-hole TO-5 metal can package with axial leads and is not compatible with SMT reflow processes. Its hermetic seal and thermal mass require wave soldering or hand-soldering with controlled thermal profiles. Attempting reflow will rupture the seal and void MIL-PRF-19500 compliance. For SMT equivalents, consider Microchip's 1N5416UR-1 (DO-41) or custom hybrid SMT Zener modules - but these lack Class J screening.
What is the maximum allowable surge current for JANTX1N5416?
JANTX1N5416 is rated for short-duration overload per MIL-PRF-19500/415: it withstands 1.5× its rated DC power (750 mW) for up to 1 second at 25°C ambient. This equates to a peak surge current of approximately 47 mA (750 mW / 16 V). Exceeding this limit risks irreversible junction damage. Unlike transient suppressors, JANTX1N5416 does not specify Ipp or waveform-dependent surge ratings - its surge capability is strictly defined by thermal time constant and package mass.
Is JANTX1N5416 compliant with RoHS or REACH regulations?
JANTX1N5416 is exempt from RoHS and REACH compliance per EU Directive 2011/65/EU Annex III, as a military-specification component manufactured prior to RoHS implementation and essential for legacy aerospace systems. Its lead content (in solder and internal bonds) and hexavalent chromium (in passivation layers) are authorized under exemption 7a. Full compliance documentation is available upon request for export-controlled programs.
