Product details
Overview
JANS1N4133D-1/TR from Microsemi is a 500 mW, 87 V, ±1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current with 1000 Ω dynamic impedance, low noise density (1 µV/√Hz), and radiation-hardened performance.
For engineers reviewing the JANS1N4133D-1/TR datasheet, JANS1N4133D-1/TR pinout, JANS1N4133D-1/TR application, or JANS1N4133D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), JANS-level qualification, DO-35 axial-leaded hermetic packaging, and low-noise regulation at 87 V for precision reference and power conditioning circuits.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 87 V at 250 mA, exhibiting a positive temperature coefficient of +0.100 %/°C and maximum reverse leakage of 0.01 µA at 69.6 V. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
Designed for high-reliability environments, JANS1N4133D-1/TR maintains regulation across -65 °C to +175 °C junction temperature range, with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length and linear power derating from 500 mW at 25 °C to zero at 175 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4133D-1 | Same electrical specs but qualified only to JANTXV level; lower screening severity than JANS | Approved for ground-based military systems but not Class S space programs | Select when full JANS screening is not required and cost sensitivity is higher |
| 1N4133DUR-1 | Same 87 V ±1% Zener voltage but in DO-213AA surface-mount package; no JANS qualification | Used in commercial or industrial PCBs where automated assembly and board space are critical | Select for reflow-compatible, high-volume production where hermetic axial leads are unnecessary |
Compared with JANS1N4133D-1/TR, JANTXV1N4133D-1 offers identical regulation performance with reduced reliability screening, while 1N4133DUR-1 trades JANS qualification and axial mounting for surface-mount compatibility and RoHS compliance - enabling trade-offs between mission assurance, manufacturability, and form factor.

FAQ
What is the Zener voltage tolerance of JANS1N4133D-1/TR?
JANS1N4133D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This tight tolerance is maintained at 250 mA test current and ensures highly accurate voltage regulation for critical reference applications in aerospace and defense systems where parameter drift is unacceptable.
Is JANS1N4133D-1/TR qualified for space applications?
Yes, JANS1N4133D-1/TR is qualified to JANS level per MIL-PRF-19500/435, which includes full Class S (space) screening requirements such as burn-in, temperature cycling, and radiation testing. Its metallurgical bond construction and hermetic DO-35 package make JANS1N4133D-1/TR suitable for use in low-Earth orbit and deep-space missions.
What does the "TR" suffix indicate in JANS1N4133D-1/TR?
The "TR" suffix in JANS1N4133D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format supports high-volume production while preserving the JANS-level qualification, traceability, and hermetic integrity of the underlying JANS1N4133D-1 device.
How does the noise performance of JANS1N4133D-1/TR compare to lower-voltage Zeners?
JANS1N4133D-1/TR exhibits a noise density of 1 µV/√Hz - consistent with the trend described in the datasheet where noise falls rapidly below 6.8 V and stabilizes at this low value for higher-voltage devices. This makes JANS1N4133D-1/TR especially valuable in high-voltage analog references where signal integrity must be preserved.
Can JANS1N4133D-1/TR replace commercial-grade 1N4133D in existing designs?
JANS1N4133D-1/TR shares identical electrical parameters (87 V ±1%, 1000 Ω ZZT, 500 mW) with commercial 1N4133D but adds JANS-level screening, hermeticity, and radiation hardness. It is a direct functional replacement where enhanced reliability is required - however, design validation must confirm mechanical fit and thermal interface compatibility due to identical DO-35 dimensions.
