Product details
Overview
JANS1N6131US/TR from Microsemi (now Microchip) is a hermetically sealed, surface-mount silicon Zener diode rated for 15 V nominal breakdown voltage, 500 mW power dissipation, and ±5% voltage tolerance, designed for precision voltage regulation and transient suppression in aerospace-grade analog power rails.
For engineers reviewing the JANS1N6131US/TR datasheet, JANS1N6131US/TR pinout, JANS1N6131US/TR application, or JANS1N6131US/TR equivalent, key selection criteria include Zener voltage accuracy at 5 mA test current, low dynamic impedance (<15 Ω), high-temperature operation up to +175°C, and MIL-PRF-19500/504 qualified screening.
Technical Context
This device operates as a two-terminal voltage reference with stable reverse-bias conduction above its specified Zener voltage. It meets Class H screening per MIL-PRF-19500 and supports operation from −65°C to +175°C ambient without derating.
The JANS1N6131US/TR exhibits a maximum Zener impedance of 15 Ω at 5 mA and a maximum leakage current of 5 µA at 12 V reverse bias, enabling reliable clamping in high-reliability analog monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V ±5% at IZ = 5 mA - defines precise clamping threshold for regulated supply rails |
| Power Dissipation (PZM) | 500 mW - sets maximum continuous thermal load under steady-state reverse bias |
| Zener Impedance (ZZT) | <15 Ω at IZ = 5 mA - ensures minimal output voltage variation during load transients |
| Maximum Leakage Current | 5 µA at 12 V - guarantees negligible quiescent current draw below regulation threshold |
| Operating Temperature | −65°C to +175°C - enables deployment in extended-range avionics and downhole electronics |
| Qualification Standard | MIL-PRF-19500/504 Class H - confirms radiation-hardened, burn-in, and life-test compliance for space applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6131US | Same Zener voltage and package, but screened to MIL-PRF-19500/504 Class V (higher reliability level) | Required for Class V programs where enhanced screening (e.g., radiation testing) is mandated | Select JANTXV1N6131US only if Class V qualification documentation and test reports are contractually required |
| 1N6131US/TR | Commercial-grade version with same electrical specs but no MIL screening or hermetic seal | Suitable for ground-based industrial prototypes where cost and lead time outweigh radiation tolerance needs | Choose 1N6131US/TR for non-flight hardware validation when JANS1N6131US/TR availability is constrained |
Compared with JANTXV1N6131US, the JANS1N6131US/TR offers identical electrical performance with Class H screening-sufficient for most flight-safety-critical subsystems-while avoiding the extended test duration and higher cost of Class V.

FAQ
What is the Zener voltage tolerance for JANS1N6131US/TR?
The JANS1N6131US/TR has a Zener voltage tolerance of ±5% at 5 mA test current, yielding a guaranteed 14.25 V to 15.75 V regulation range. This tolerance is maintained across the full −65°C to +175°C operating temperature range and is verified per MIL-PRF-19500/504 Class H screening requirements. The JANS1N6131US/TR datasheet specifies this value under both room-temperature and high-temperature test conditions.
Is JANS1N6131US/TR compatible with lead-free reflow soldering processes?
Yes, the JANS1N6131US/TR uses a DO-213AB glass package qualified for standard lead-free reflow profiles, including peak temperatures up to 260°C for 30 seconds. Its hermetic seal remains intact under JEDEC J-STD-020D-compliant thermal cycling. The JANS1N6131US/TR mounting instructions specify preheat ramp rates and cooling profiles to prevent glass fracture during assembly.
Does JANS1N6131US/TR require derating above 70°C ambient?
No, the JANS1N6131US/TR is rated for full 500 mW power dissipation from −65°C to +175°C ambient without derating. Its thermal resistance (RθJA) is characterized across the entire range, and MIL-PRF-19500/504 Class H screening validates sustained operation at maximum junction temperature. The JANS1N6131US/TR datasheet provides derating curves only for non-standard mounting configurations.
What is the maximum reverse leakage current specification for JANS1N6131US/TR?
The JANS1N6131US/TR has a maximum reverse leakage current of 5 µA at 12 V reverse bias and +25°C, tightening to 10 µA at +175°C. These values are measured per MIL-PRF-19500/504 test method 301.1 and confirmed for every production lot. The JANS1N6131US/TR maintains low leakage even after 1000-hour life testing at rated voltage and temperature.
Can JANS1N6131US/TR be used as a replacement for commercial 1N6131 in existing designs?
JANS1N6131US/TR shares identical electrical parameters and DO-213AB package dimensions with commercial 1N6131 variants, but adds hermetic sealing and MIL screening. It can replace 1N6131 in designs requiring enhanced reliability-however, layout and thermal design must accommodate its higher cost and longer lead times. The JANS1N6131US/TR should not be substituted without verifying qualification documentation for the target application environment.
