For engineers reviewing the JAN1N4131D-1/TR datasheet, JAN1N4131D-1/TR pinout, JAN1N4131D-1/TR application, or JAN1N4131D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), dynamic impedance (700 Ω at 250 mA), temperature coefficient (+0.100 %/°C), and JANS-level radiation hardness.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 75 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable regulation across -65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
The JAN1N4131D-1/TR features a maximum reverse leakage current of 0.01 µA at 60 V and dynamic impedance of 700 Ω at IZT, enabling precise voltage reference stability in low-current, high-impedance feedback paths typical of analog instrumentation and satellite power subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4131US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Used where PCB real estate is constrained and automated SMT assembly required | Select when transitioning from through-hole to SMT or when vibration resistance demands no lead flexure |
| JANTXV1N4131D | Identical Zener voltage, tolerance, and reliability level but lacks TR tape-and-reel packaging | Preferred for manual prototyping or low-volume hand-soldered assemblies | Select when reel packaging is unnecessary and JANTXV qualification suffices for program requirements |
Compared with JAN1N4131D-1/TR, 1N4131US-1 offers identical regulation performance in a smaller footprint but requires reflow-compatible layout, while JANTXV1N4131D provides matching reliability without tape-and-reel convenience-both serve distinct production and qualification needs without altering core circuit function.

FAQ
What is the Zener voltage tolerance of JAN1N4131D-1/TR?
JAN1N4131D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This tight tolerance is verified per MIL-PRF-19500/435 testing and applies at 250 mA test current and 25 °C ambient. The 75 V nominal Zener voltage remains within 74.25 V to 75.75 V across qualified units, supporting high-accuracy reference designs without post-manufacturing trimming.
Is JAN1N4131D-1/TR qualified for space applications?
Yes, JAN1N4131D-1/TR is qualified to JANS level per MIL-PRF-19500/435, which includes radiation hardness assurance per Microsemi MicroNote 050. Its metallurgically bonded DO-35 construction, hermetic sealing, and tested performance from -65 °C to +175 °C make it suitable for low-earth orbit (LEO) and geosynchronous satellite power and reference subsystems where total ionizing dose (TID) resilience is required.
What does the "TR" suffix indicate in JAN1N4131D-1/TR?
The "TR" suffix in JAN1N4131D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This packaging option is factory-verified and compatible with standard SMT feeders. The underlying device remains electrically and mechanically identical to the bulk version, with no impact on Zener voltage, noise density, or reliability qualification.
How does the noise density of JAN1N4131D-1/TR compare to lower-voltage Zeners?
JAN1N4131D-1/TR exhibits a noise density of 1 µV/√Hz, consistent with higher-voltage Zeners in the 1N4128–1N4135 series. This is significantly lower than mid-range Zeners (e.g., 6.8 V devices at 40 µV/√Hz) due to reduced avalanche noise contribution. The low noise supports use in precision analog circuits such as spectroscopy front-ends and high-resolution data acquisition references where signal integrity is paramount.
Can JAN1N4131D-1/TR replace commercial-grade 1N4131D-1 in existing designs?
JAN1N4131D-1/TR can replace commercial-grade 1N4131D-1 only if the design requires JANS-level reliability, radiation hardness, or extended temperature operation. Electrically, both share identical Zener voltage, tolerance, and dynamic impedance. However, JAN1N4131D-1/TR undergoes additional screening per MIL-PRF-19500/435, including burn-in and lot acceptance testing-making it appropriate for life-critical systems where field failure is unacceptable.
