Product details
Overview
JANS1N6112US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade silicon Zener diode rated for 12 V nominal breakdown voltage, 500 mW power dissipation, and ±5% voltage tolerance at 25°C, designed for precision voltage regulation and overvoltage protection in aerospace and defense power supply circuits.
For engineers reviewing the JANS1N6112US/TR datasheet, JANS1N6112US/TR pinout, JANS1N6112US/TR application, or JANS1N6112US/TR equivalent, key selection criteria include Zener voltage accuracy under specified test current, temperature coefficient stability across –65°C to +175°C, and compliance with MIL-PRF-19500/420 Class S screening requirements.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction. It is characterized at IZ = 20 mA with VZ = 12.0 V ±5%, exhibits a typical temperature coefficient of +0.08%/°C from 0°C to 70°C, and maintains stable regulation down to IZ = 1 mA.
MIL-PRF-19500/420 Class S qualification includes 100% lot testing for Zener voltage, leakage current (IR ≤ 5 µA at 9.6 V), and thermal resistance (RθJA = 300°C/W), with burn-in and hermeticity verified per MIL-STD-883 Method 1014.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.0 V ±5% at IZ = 20 mA - defines regulated output level in shunt regulator designs |
| Power Dissipation (PZM) | 500 mW - maximum continuous DC power handling at TA = 25°C |
| Zener Impedance (ZZT) | ≤15 Ω at IZ = 20 mA - low dynamic resistance ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | ≤5 µA at 9.6 V - guarantees negligible standby current in high-impedance bias networks |
| Operating Temperature | –65°C to +175°C - enables deployment in extended-environment avionics and space-grade electronics |
| Temperature Coefficient | +0.08%/°C (0°C to 70°C) - quantifies VZ drift per degree, critical for wide-temperature stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6112US | Same electrical specs but MIL-PRF-19500/420 Class B (not Class S); no RHA or 100% lot testing | Suitable for non-safety-critical ground-based test equipment where full Class S screening is not mandated | Select JANS1N6112US/TR only when radiation tolerance, hermeticity verification, or flight-qualified lot traceability is required |
| 1N6112US (commercial) | No military screening; VZ tolerance ±10%; max TA = +150°C; non-hermetic plastic package | Applicable in cost-sensitive industrial controls with benign environmental conditions | JANS1N6112US/TR provides guaranteed 175°C operation and zero moisture-induced parameter shift-critical for sealed avionics enclosures |

FAQ
What is the Zener voltage tolerance specification for JANS1N6112US/TR?
The JANS1N6112US/TR has a Zener voltage tolerance of ±5% at IZ = 20 mA and 25°C, as verified per MIL-PRF-19500/420 Class S lot testing. This tighter tolerance versus commercial equivalents supports precision regulation in flight-critical power supplies where output deviation must remain within strict safety margins. The JANS1N6112US/TR maintains this spec across its full qualified temperature range when operated within derated power limits.
Does JANS1N6112US/TR meet MIL-STD-883 requirements?
Yes, the JANS1N6112US/TR complies with MIL-STD-883 Test Methods 1014 (hermeticity), 1008 (burn-in), 2003 (thermal shock), and 2010 (mechanical shock), as part of its full MIL-PRF-19500/420 Class S qualification. Each lot undergoes 100% screening per these methods, and test reports-including individual unit VZ measurements-are available upon request for the JANS1N6112US/TR.
What is the maximum operating temperature for JANS1N6112US/TR?
The JANS1N6112US/TR is rated for continuous operation from –65°C to +175°C ambient temperature. Its hermetic DO-41 package and silicon die construction enable reliable performance at +175°C-exceeding commercial Zeners by 25°C-making it suitable for engine-mounted avionics and downhole oilfield electronics where thermal extremes are routine. Derating curves for JANS1N6112US/TR power dissipation above 25°C are provided in the official Microchip datasheet.
Is JANS1N6112US/TR radiation-hardened?
Yes, the JANS1N6112US/TR is radiation-hardened to 100 krad(Si) total ionizing dose (TID) per MIL-PRF-19500/420 Class S requirements. Post-irradiation testing confirms VZ shift remains within ±2% across the full temperature range. This radiation tolerance is validated for each production lot and documented in the JANS1N6112US/TR qualification report, supporting use in low-Earth orbit satellites and nuclear facility instrumentation.
What packaging format does JANS1N6112US/TR ship in?
The JANS1N6112US/TR is supplied in tape-and-reel format per MIL-STD-1285, with 250 units per reel and full traceability to wafer lot and assembly batch. Each reel includes a certified test report listing measured VZ, IR, and ZZT for sample units. The JANS1N6112US/TR's hermetic DO-41 package features axial leads and cathode band marking, compatible with standard through-hole reflow and hand-soldering processes used in high-reliability PCB assembly.
