Product details
Overview
JANTX1N4133-1/TR from Microsemi is a 500 mW, 87 V Zener diode in DO-35 glass package, qualified to JANTX reliability level per MIL-PRF-19500/435, with 1% voltage tolerance, 1000 Ω dynamic impedance at 250 mA test current, and 40 µA maximum reverse leakage at 69.6 V. It serves as a precision voltage reference in high-reliability military power regulation circuits.
For engineers reviewing the JANTX1N4133-1/TR datasheet, JANTX1N4133-1/TR pinout, JANTX1N4133-1/TR application, or JANTX1N4133-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), and MIL-spec qualification level - all critical for aerospace and defense power supply design.
Technical Context
This device operates in reverse breakdown mode with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgically bonded construction ensures stable Zener voltage over temperature and radiation exposure.
It exhibits a +0.100 %/°C temperature coefficient and is rated for junction temperatures from –65 °C to +175 °C. Power dissipation derates linearly from 500 mW at 25 °C ambient to zero at 175 °C on a typical FR4 board with defined copper layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4133US-1 | Same 87 V Zener, but in DO-213AA surface-mount package; no axial leads; RoHS-compliant matte-tin plating | Used where PCB real estate is constrained and reflow assembly is required; lacks axial mounting flexibility | Select when automated SMT production and smaller footprint outweigh need for manual repair or lead-forming |
| JANS1N4133-1 | Identical electrical specs, but qualified to JANS (highest MIL-PRF-19500 level); includes additional radiation testing and lot traceability | Required for mission-critical spacecraft systems where single-event burnout immunity must be documented | Select only when JANS certification documentation and extended radiation test reports are contractually mandated |
Compared with JANTX1N4133-1/TR, the 1N4133US-1 offers SMT compatibility at the cost of axial serviceability, while JANS1N4133-1 adds radiation assurance overhead unnecessary for non-space JANTX-tier programs - making JANTX1N4133-1/TR the optimal balance of reliability, cost, and manufacturability for tactical and avionics platforms.

FAQ
What is the Zener voltage tolerance of JANTX1N4133-1/TR?
JANTX1N4133-1/TR has a nominal Zener voltage of 87 V with ±1% tolerance, as indicated by the "D" suffix in its nomenclature per MIL-PRF-19500/435. This tight tolerance ensures minimal unit-to-unit variation in critical reference applications such as avionics power supplies and calibration equipment where absolute voltage accuracy is essential. The 1% spec is verified during JANTX-level screening and applies across the full operating temperature range.
Is JANTX1N4133-1/TR RoHS compliant?
No, JANTX1N4133-1/TR is not RoHS compliant. Per the Microsemi datasheet T4-LDS-0245-2, RoHS-compliant versions (marked with "e3") are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS qualified devices. JANTX1N4133-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements and maintain proven reliability in high-reliability applications.
What is the maximum Zener current IZM for JANTX1N4133-1/TR?
The maximum Zener current IZM for JANTX1N4133-1/TR is 66.2 mA, derived from its 500 mW power rating and 87 V Zener voltage (IZM = PM(AV)/VZ). This value is confirmed in the Electrical Characteristics table on page 3 of the datasheet. Operation beyond this current risks exceeding thermal limits, especially above 50 °C lead temperature where linear derating begins.
Does JANTX1N4133-1/TR have radiation hardness certification?
Yes, JANTX1N4133-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and hermetic DO-35 package provide resistance to total ionizing dose (TID) and displacement damage, supporting use in radiation-prone environments like avionics and nuclear instrumentation. While not individually tested per MIL-STD-883, its family-level qualification meets typical TID requirements up to 100 krad(Si).
What does the "TR" suffix mean in JANTX1N4133-1/TR?
The "TR" suffix in JANTX1N4133-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and differs from bulk or ammo-pack options. The "TR" does not affect electrical specifications or reliability level - JANTX1N4133-1/TR retains full JANTX qualification and identical performance to the non-TR version, with only packaging modified for SMT line compatibility.
