Product details
Overview
JANTX1N4133D-1/TR from Microsemi is a 500 mW, 87 V, ±1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4133D-1/TR datasheet, JANTX1N4133D-1/TR pinout, JANTX1N4133D-1/TR application, or JANTX1N4133D-1/TR equivalent, key selection factors include its 87 V nominal Zener voltage at 250 mA test current, 1000 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 69.6 V, ±1% voltage tolerance, and radiation-hardened hermetic DO-35 construction.
Technical Context
This device operates as a precision shunt voltage regulator with a specified Zener voltage of 87 V at IZT = 250 mA, exhibiting low noise density (1 µV/√Hz typical) and stable temperature coefficient (+0.100 %/°C). Its metallurgical bond ensures mechanical robustness under thermal cycling and shock.
Designed for operation in the breakdown region, it maintains regulation across wide current ranges (IZK to IZM = 40 mA to 66.2 mA), with dynamic impedance measured at 10% AC modulation of IZT and derated linearly from 500 mW at 25 °C to zero at 175 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4133US-1 | Same 87 V Zener voltage and ±1% tolerance, but in surface-mount DO-213AA package | Requires rework of through-hole layout; better suited for automated SMT assembly and higher board density | Select when migrating to surface-mount manufacturing or minimizing board area |

FAQ
What is the Zener voltage and test current for JANTX1N4133D-1/TR?
JANTX1N4133D-1/TR has a nominal Zener voltage of 87 V measured at a test current (IZT) of 250 mA. This value is guaranteed within ±1% tolerance and is specified under thermal equilibrium at 25 °C ambient. The device maintains regulation across a wide current range from 40 mA to 66.2 mA, supporting flexible design margins in power supply feedback loops.
Is JANTX1N4133D-1/TR RoHS compliant?
No, JANTX1N4133D-1/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (suffix e3) are available only for commercial-grade variants, not for JANTX-level qualified parts. JANTX1N4133D-1/TR uses traditional tin-lead plating on its DO-35 leads to meet MIL-STD-750 solderability requirements and ensure long-term reliability in high-reliability applications.
What is the maximum power dissipation and derating behavior of JANTX1N4133D-1/TR?
JANTX1N4133D-1/TR has a rated average power dissipation of 500 mW at 25 °C lead temperature. Power must be linearly derated starting at 50 °C lead temperature, reaching zero at 175 °C. On a typical FR4 board with 1 oz copper, derating begins at 25 °C ambient and follows the same linear slope, ensuring safe operation across military temperature ranges without thermal runaway.
How does the dynamic impedance of JANTX1N4133D-1/TR affect regulation accuracy?
JANTX1N4133D-1/TR has a maximum dynamic impedance (ZZT) of 1000 Ω at 250 mA test current. This value directly impacts output voltage variation under load changes: for example, a 10 mA load step causes up to 10 V deviation (1000 Ω × 10 mA). Designers must account for this in feedback loop compensation and select appropriate series resistance to maintain stability in shunt regulator configurations.
What packaging and marking details apply to JANTX1N4133D-1/TR?
JANTX1N4133D-1/TR is supplied in DO-35 (DO-204AH) hermetically sealed axial-glass package with cathode indicated by a visible band. The "TR" suffix denotes tape-and-reel packaging per EIA-296 standard. Marking includes full part number "JANTX1N4133D-1" laser-etched or ink-stamped on the glass body, enabling full traceability to MIL-PRF-19500/435 qualification lots.
