Product details
Overview
JANTXV1N4133D-1 from Microsemi is a 500 mW, 87 V Zener diode in DO-35 glass package with 1% voltage tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 JANTXV qualification for high-reliability aerospace and defense power regulation applications.
For engineers reviewing the JANTXV1N4133D-1 datasheet, JANTXV1N4133D-1 pinout, JANTXV1N4133D-1 application, or JANTXV1N4133D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, hermetic glass sealing, and thermal resistance (RθJL = 250 °C/W at 10 mm lead length).
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, delivering stable 87 V regulation across 250 mA test current and wide temperature range (–65 to +175 °C). Its metallurgical bond ensures mechanical integrity under thermal cycling and shock.
Designed for high-reliability systems, JANTXV1N4133D-1 exhibits minimal capacitance (typ. <1.5 pF), low leakage (<0.01 µA at 69.6 V), and inherent radiation hardness per Microsemi MicroNote 050 - critical for space-grade analog biasing and voltage clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Power Dissipation | 500 mW at TC = 25 °C - supports continuous regulation without forced cooling in compact chassis-mount designs. |
| Dynamic Impedance ZZT | 1000 Ω max - ensures stable output under varying load currents typical in feedback sensing circuits. |
| Noise Density | 1 µV/√Hz - minimizes voltage reference jitter in precision instrumentation and ADC reference buffers. |
| Reverse Leakage IR | ≤0.01 µA at VR = 69.6 V - guarantees negligible standby current in battery-backed hold-up circuits. |
| Temp. Coefficient αVZ | +0.100 %/°C - allows predictable drift compensation in temperature-stable reference networks. |
| Junction Temp. Range | –65 to +175 °C - qualified for operation in extreme environments including avionics and downhole electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4133D-1 | JANS-level qualification (higher screening than JANTXV), same VZ, tolerance, and package. | Required for Class S spaceflight hardware; adds extended life test and lot acceptance testing. | Select when full MIL-PRF-19500/435 Class S compliance is mandated for launch-critical systems. |
| 1N4133UR-1 | DO-213AA surface-mount package; identical electrical specs but no military qualification. | Used in commercial-grade industrial controllers where board space is constrained and radiation tolerance is not required. | Choose for cost-sensitive terrestrial applications needing same 87 V regulation without mil-spec screening. |
Compared with JANS1N4133D-1, the JANTXV1N4133D-1 offers reduced test overhead while maintaining identical Zener performance and hermetic reliability; versus 1N4133UR-1, it trades surface-mount convenience for proven radiation hardness and extended temperature operation.

FAQ
What is the Zener voltage tolerance of JANTXV1N4133D-1?
JANTXV1N4133D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This means its nominal 87 V Zener voltage is guaranteed between 86.13 V and 87.87 V at IZT = 250 mA and TA = 25 °C. This tight tolerance eliminates need for post-assembly calibration in high-accuracy reference circuits.
Is JANTXV1N4133D-1 RoHS compliant?
No, JANTXV1N4133D-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants, not for JANTXV-qualified parts. The JANTXV1N4133D-1 uses traditional tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under thermal stress.
What is the maximum reverse leakage current for JANTXV1N4133D-1?
The maximum reverse leakage current (IR) for JANTXV1N4133D-1 is 0.01 µA at VR = 69.6 V (80% of VZ). This ultra-low leakage ensures minimal power loss in standby modes and preserves accuracy in high-impedance reference divider networks used in precision analog front-ends.
Can JANTXV1N4133D-1 be used in surface-mount designs?
No, JANTXV1N4133D-1 is packaged exclusively in the axial-leaded DO-35 (DO-204AH) glass case. For surface-mount equivalents, consider the commercial-grade 1N4133UR-1 in DO-213AA - but note it lacks JANTXV qualification, radiation hardness, and hermetic sealing required for aerospace use.
What is the thermal resistance junction-to-lead for JANTXV1N4133D-1?
JANTXV1N4133D-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured at 10 mm lead length from the package body. This value enables accurate thermal modeling for chassis-mounted heatsinking and confirms safe operation up to 175 °C junction temperature with appropriate lead termination design.
