Product details
Overview
JANTXV1N4128D-1/TR from Microsemi is a 60 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4128D-1/TR datasheet, JANTXV1N4128D-1/TR pinout, JANTXV1N4128D-1/TR application, or JANTXV1N4128D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (≤1 µV/√Hz), radiation hardness, hermetic DO-35 packaging, and military-grade thermal derating behavior.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 60.0 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 400 Ω at IZT. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability environments, JANTXV1N4128D-1/TR maintains ≤0.01 µA reverse leakage at VR = 45.6 V and supports full-rated power dissipation up to 50 °C before linear derating 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 |
|---|---|---|---|
| JANTXV1N4128US-1 | Same 60 V, 1% Zener voltage but in surface-mount DO-213AA package | Requires rework of PCB layout for SMT assembly; no axial through-hole mounting option | Select when automated assembly and board space reduction outweigh manual soldering requirements |
| 1N4128UR-1TR | Commercial-grade (non-military) version with same electrical specs but only JAN/JANTX qualification | Lacks JANTXV-level screening and radiation hardness documentation | Select for cost-sensitive industrial applications where MIL-spec screening is not mandated |
Compared with JANTXV1N4128D-1/TR, JANTXV1N4128US-1 offers identical regulation performance in a smaller footprint but sacrifices axial-leaded serviceability, while 1N4128UR-1TR reduces procurement cost and lead time but omits JANTXV qualification evidence required for DoD programs.

FAQ
What is the Zener voltage tolerance for JANTXV1N4128D-1/TR?
JANTXV1N4128D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This means its nominal 60.0 V Zener voltage is guaranteed between 59.4 V and 60.6 V at 250 mA test current and 25 °C ambient, meeting stringent requirements for precision reference applications.
Is JANTXV1N4128D-1/TR RoHS compliant?
No, JANTXV1N4128D-1/TR is not RoHS compliant. Per the Microsemi datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants, not for JANTXV-level military-qualified parts like JANTXV1N4128D-1/TR.
What is the maximum reverse leakage current for JANTXV1N4128D-1/TR?
The maximum reverse leakage current (IR) for JANTXV1N4128D-1/TR is 0.01 µA at VR = 45.6 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports high-impedance bias networks and minimizes standby power loss.
Does JANTXV1N4128D-1/TR require heatsinking in normal operation?
JANTXV1N4128D-1/TR does not require external heatsinking at ambient temperatures ≤50 °C due to its 500 mW rating and 250 °C/W junction-to-lead thermal resistance. However, above 50 °C, power must be linearly derated to zero at 175 °C junction temperature per Figure 2 in the datasheet.
How is polarity marked on JANTXV1N4128D-1/TR?
JANTXV1N4128D-1/TR uses a cathode band marking: the banded end is the cathode terminal, which must be held at higher potential than the unbanded (anode) end for Zener regulation. Forward voltage drop is 1.1 V at 200 mA, confirming standard silicon diode polarity orientation.
