Product details
Overview
JANTXV1N4127D-1/TR from Microsemi is a 56 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435, used for precision voltage regulation in military and aerospace power supply reference circuits.
For engineers reviewing the JANTXV1N4127D-1/TR datasheet, JANTXV1N4127D-1/TR pinout, JANTXV1N4127D-1/TR application, or JANTXV1N4127D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), temperature coefficient (+0.100 %/°C), noise density (1 µV/√Hz), max reverse current (10 nA @ 42.6 V), and hermetic DO-35 packaging for high-reliability environments.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring reverse-bias operation where the banded end is positive relative to the anode. Its metallurgical bond ensures stable junction characteristics across -65 °C to +175 °C operating range and radiation hardness per MicroNote 050.
It delivers regulated output at 56 V with 250 mA test current (IZT), dynamic impedance of 300 Ω at IZT, and exhibits low capacitance (typ. <2 pF) and minimal noise-critical for analog sensing and precision feedback loops in avionics and satellite power systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4127US-1TR | Same 56 V, 1% spec but in surface-mount DO-213AA package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used |

FAQ
What is the Zener voltage tolerance of JANTXV1N4127D-1/TR?
JANTXV1N4127D-1/TR has a nominal Zener voltage of 56.0 V with a tolerance of ±1%, as indicated by the "D" suffix in its part number per MIL-PRF-19500/435 nomenclature. This tight tolerance is verified during JANTXV-level screening and supports high-accuracy reference designs without post-manufacturing calibration.
Is JANTXV1N4127D-1/TR RoHS compliant?
No, JANTXV1N4127D-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions of this series; JANTXV-level devices retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability in high-reliability applications.
What is the maximum reverse current for JANTXV1N4127D-1/TR?
The maximum reverse current (IR) for JANTXV1N4127D-1/TR is 10 nA measured at 42.6 V (75% of VZ), per the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This ultra-low leakage supports use in high-impedance bias networks and battery-powered systems.
Can JANTXV1N4127D-1/TR be used in surface-mount designs?
No-JANTXV1N4127D-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4127US-1TR in DO-213AA package, which shares identical electrical specifications but requires reflow-compatible mounting.
What is the temperature coefficient of JANTXV1N4127D-1/TR?
The temperature coefficient (αVZ) of JANTXV1N4127D-1/TR is +0.100 %/°C, meaning its Zener voltage increases by 0.056 V per 1 °C rise in junction temperature. This value is specified in the Electrical Characteristics table and confirmed for JANTXV-qualified units.
