Product details
Overview
JANTXV1N4127D-1 from Microsemi is a 56 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4127D-1 datasheet, JANTXV1N4127D-1 pinout, JANTXV1N4127D-1 application, or JANTXV1N4127D-1 equivalent, this part delivers precise 56 V regulation with ±1% initial tolerance, low noise density (1 µV/√Hz), and radiation-hardened operation across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable 56 V output across load current variations from 1 mA to 42.6 mA while exhibiting dynamic impedance of 300 Ω at 250 mA test current. Its internal metallurgical bond ensures mechanical robustness under thermal cycling and shock.
Designed for military-grade reliability, JANTXV1N4127D-1 features hermetically sealed glass construction, non-ESD-sensitive behavior per MIL-STD-750 Method 1020, and a positive temperature coefficient of +0.100 %/°C - enabling predictable drift compensation in precision reference circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 56 V ±1% at 250 mA - provides tight reference accuracy for critical analog subsystems. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - supports operation in high-temp avionics enclosures. |
| Dynamic Impedance ZZT | 300 Ω at IZT = 250 mA - ensures minimal output voltage variation under dynamic load transients. |
| Noise Density | 1 µV/√Hz - enables use in low-noise voltage references for ADC biasing and sensor excitation. |
| Temp Coefficient αVZ | +0.100 %/°C - allows predictable thermal drift modeling in wide-temperature-range designs. |
| Max Reverse Current IR | 10 nA at 42.6 V - guarantees low leakage in high-impedance reference divider networks. |
| Junction Temp Range | –65 °C to +175 °C - meets extended environmental requirements for space and engine-control applications. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by color band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink terminal during forward conduction | Connected to circuit ground or lower-potential node when used in reverse-biased Zener mode. |
| Cathode (banded end) | Regulated voltage output terminal | Connected to regulated rail; polarity must be observed - banded end is positive relative to anode for Zener operation. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4127US-1 | Same 56 V, 1% spec but in DO-213AA surface-mount package; RθJA = 400 °C/W vs. 300 °C/W for DO-35. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting. | Select when board space is constrained and thermal management via copper pour is feasible. |
| JANS1N4127D-1 | Identical electrical specs and DO-35 package, but qualified to JANS level with additional burn-in, radiation testing, and lot acceptance test per MIL-PRF-19500/435. | Required for Class K (spaceflight) and Class H (nuclear) applications where full JANS screening is mandated. | Choose only when JANS certification documentation and traceability are contractually required. |
Compared with JANTXV1N4127D-1, the 1N4127US-1 trades mechanical ruggedness and thermal performance for miniaturization, while JANS1N4127D-1 adds cost and lead time to meet highest-tier qualification without altering baseline regulation behavior.

FAQ
What is the Zener voltage tolerance and test condition for JANTXV1N4127D-1?
JANTXV1N4127D-1 has a nominal Zener voltage of 56 V with ±1% tolerance, measured at 250 mA test current (IZT) and 25 °C ambient temperature. This tolerance is achieved via post-process binning and verified per MIL-PRF-19500/435 screening requirements for JANTXV-level devices.
Does JANTXV1N4127D-1 require heatsinking in standard PCB layouts?
JANTXV1N4127D-1 does not require external heatsinking for operation at ≤500 mW up to 50 °C ambient, thanks to its 250 °C/W junction-to-lead thermal resistance. At higher temperatures, linear derating applies - power drops to zero at 175 °C junction temperature per Figure 2 in the datasheet.
Is JANTXV1N4127D-1 RoHS compliant?
No - JANTXV1N4127D-1 is not RoHS compliant. The JANTXV qualification level uses traditional tin-lead plating per MIL-STD-750 Method 2026. RoHS-compliant versions (e3 suffix) are only available for commercial-grade parts like 1N4127D-1e3, not for JANTXV or higher reliability levels.
How is polarity marked on JANTXV1N4127D-1?
JANTXV1N4127D-1 uses a single color band near one end of the DO-35 glass body to indicate the cathode terminal. For proper Zener regulation, the banded (cathode) end must be held at a more positive potential than the anode end - reverse-bias configuration.
What is the maximum reverse leakage current for JANTXV1N4127D-1 at rated voltage?
At 42.6 V reverse voltage (0.76 × VZ), JANTXV1N4127D-1 exhibits a maximum reverse current (IR) of 10 nA, measured at 25 °C. This ultra-low leakage supports high-impedance reference networks without significant error contribution.
