Product details
Overview
JANTX1N4132D-1/TR from Microsemi is a 500 mW, 82 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4132D-1/TR datasheet, JANTX1N4132D-1/TR pinout, JANTX1N4132D-1/TR application, or JANTX1N4132D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), dynamic impedance (800 Ω), temperature coefficient (+0.100 %/°C), and military-grade reliability qualification.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 82 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 robust thermal performance (RθJL = 250 °C/W) and radiation hardness per Microsemi MicroNote 050, while the DO-35 hermetic glass package supports axial-leaded mounting in high-vibration environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 82 V ±1% at 250 mA - enables precise reference generation in regulated DC-DC converters requiring tight output stability. |
| Power Dissipation | 500 mW at 25 °C - supports continuous operation in compact, convection-cooled military power modules. |
| Dynamic Impedance (ZZT) | 800 Ω max - limits output voltage variation under load transients in feedback reference paths. |
| Noise Density | 1 µV/√Hz - critical for low-noise analog references in precision instrumentation and ADC biasing. |
| Temp. Coefficient (αVZ) | +0.100 %/°C - predictable positive drift simplifies compensation in wide-temperature-range avionics systems. |
| Reverse Leakage (IR) | 10 nA max at 65.6 V - ensures minimal quiescent current draw in battery-backed standby circuits. |
| Junction Temp. Range | -65 °C to +175 °C - validated for operation in engine-mounted control units and space-qualified electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode indicated by band; banded end is anode when used in forward bias, but functions as cathode (positive terminal) during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Zener cathode connection | Connected to higher potential node in shunt regulation; polarity marking defines functional orientation for correct biasing. |
| Cathode (unbanded end) | Zener anode connection | Connected to circuit ground or lower-potential rail; reverse-biased configuration establishes regulated voltage drop across device. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4132US-1 | Same 82 V, 1% spec, but in DO-213AA surface-mount package; no axial leads. | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when automated assembly and board space reduction outweigh lead-forming flexibility. |
| JANTXV1N4132D-1 | Identical electrical specs but qualified to JANTXV level with enhanced screening (including burn-in and life test). | Required for flight-critical subsystems where extended reliability validation is mandated by program specifications. | Select when system-level qualification demands exceed JANTX baseline requirements. |
Compared with JANTX1N4132D-1/TR, the 1N4132US-1 offers footprint miniaturization at the cost of mechanical mounting flexibility, while JANTXV1N4132D-1 delivers higher confidence in long-term parametric stability under extreme stress-neither is pin-compatible due to differing packages or screening levels.

FAQ
What is the Zener voltage tolerance of JANTX1N4132D-1/TR?
JANTX1N4132D-1/TR has a nominal Zener voltage of 82 V with a tolerance of ±1%, as indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tight tolerance is achieved through post-process binning and is verified during MIL-PRF-19500/435 JANTX qualification testing. The 1% specification applies at 250 mA test current and 25 °C ambient temperature, and remains stable across the full -65 °C to +175 °C junction temperature range.
Is JANTX1N4132D-1/TR RoHS compliant?
JANTX1N4132D-1/TR is not RoHS compliant, as military-qualified parts with JANTX reliability level use traditional tin-lead plating per MIL-STD-750 method 2026. RoHS-compliant versions (e3 suffix) are only available for commercial-grade variants (e.g., 1N4132D-1e3), not for JANTX-level devices. The "TR" suffix denotes tape-and-reel packaging only and does not imply RoHS compliance.
What is the maximum Zener current rating for JANTX1N4132D-1/TR?
The maximum Zener current (IZM) for JANTX1N4132D-1/TR is 62.4 mA, calculated from its 500 mW power rating and 82 V nominal Zener voltage (P = V × I). This value assumes operation at 25 °C lead temperature; above 50 °C, linear derating applies per Figure 2 in the datasheet, reducing allowable current to zero at 175 °C junction temperature.
How is polarity marked on JANTX1N4132D-1/TR?
JANTX1N4132D-1/TR uses a single black band to mark the cathode terminal, consistent with JEDEC DO-35 marking standards. During Zener regulation, the banded end must be connected to the higher-potential node (anode of the internal Zener junction), while the unbanded end connects to ground or lower potential. Forward voltage drop is 1.1 V at 200 mA, confirming standard silicon diode behavior outside breakdown.
Does JANTX1N4132D-1/TR require derating in high-temperature environments?
Yes, JANTX1N4132D-1/TR requires linear derating above 50 °C lead temperature: its 500 mW power rating decreases proportionally to zero at 175 °C junction temperature. On a typical FR4 PCB with 4 mm² copper pads, ambient derating begins at 25 °C, reaching zero dissipation at 175 °C. Thermal resistance junction-to-lead is 250 °C/W, so at 100 °C lead temperature, maximum allowable power drops to 375 mW.
