Product details
Overview
JANTXV1N4128D-1 from Microsemi is a 60 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JANTXV1N4128D-1 datasheet, JANTXV1N4128D-1 pinout, JANTXV1N4128D-1 application, or JANTXV1N4128D-1 equivalent, key selection factors include its 60 V nominal Zener voltage at 250 mA test current, 400 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 48 V, +0.100 %/°C temperature coefficient, and hermetically sealed axial-leaded construction.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring forward biasing of the banded end for Zener regulation. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure.
It delivers regulated output across wide current ranges (IZK to IZM = 45.6 mA max) with low noise density (≤1 µV/√Hz below 6.8 V), minimal capacitance (typical <2 pF at 60 V), and linear power derating from 500 mW at 25 °C to zero at 175 °C.
Key Specifications

| Nominal Zener Voltage | 60.0 V at 250 mA test current - defines precise regulation point for reference design |
| Zener Tolerance | ±1% - enables high-accuracy voltage references without post-calibration |
| Power Dissipation | 500 mW at 25 °C lead temperature - supports stable operation in compact, unheatsinked layouts |
| Dynamic Impedance | 400 Ω max at 250 mA - limits output voltage variation under load transients |
| Reverse Leakage | 0.01 µA max at 48 V - ensures negligible error current in high-impedance reference nodes |
| Temp. Coefficient | +0.100 %/°C - quantifies drift magnitude for thermal compensation planning |
| Junction Temp. Range | –65 to +175 °C - validated for extended-range military and space environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4128US-1 | Same 60 V/1% spec but in DO-213AA surface-mount package | Requires PCB rework for SMT assembly; no axial through-hole mounting | Select when board space constraints mandate surface-mount integration |
| JANTXV1N4128-1 | Identical electrical specs but ±5% Zener tolerance instead of ±1% | Higher initial calibration burden in precision reference designs | Select when cost sensitivity outweighs tight tolerance requirements |
Compared with JANTXV1N4128D-1, the JANTXV1N4128-1 offers lower cost but requires system-level trimming, while the 1N4128US-1 enables miniaturized layouts at the expense of mechanical mounting flexibility and thermal resistance.

FAQ
What is the Zener voltage tolerance of JANTXV1N4128D-1?
JANTXV1N4128D-1 has a nominal Zener voltage of 60.0 V with a ±1% tolerance, verified per MIL-PRF-19500/435 test conditions at 250 mA test current. This tight tolerance eliminates post-manufacturing calibration in high-accuracy reference designs and is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1.
Is JANTXV1N4128D-1 RoHS compliant?
No, JANTXV1N4128D-1 is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. JANTXV1N4128D-1 carries the JANTXV reliability level and uses tin-lead plating per MIL-STD-750 method 2026.
What is the maximum Zener current for JANTXV1N4128D-1?
The maximum Zener current (IZM) for JANTXV1N4128D-1 is 45.6 mA, calculated from its 500 mW power rating and 60 V nominal Zener voltage. This value is explicitly listed in the Electrical Characteristics table on page 3 and assumes operation at 25 °C lead temperature with linear derating above 50 °C.
Does JANTXV1N4128D-1 have radiation hardness certification?
Yes, JANTXV1N4128D-1 is inherently radiation hard as described in Microsemi MicroNote 050. Its metallurgically bonded construction and glass DO-35 package provide tolerance to total ionizing dose (TID) and displacement damage, making it suitable for low-earth orbit and nuclear instrumentation without additional shielding.
What is the thermal resistance junction-to-lead for JANTXV1N4128D-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4128D-1 is 250 °C/W, measured with 10 mm (3/8 inch) lead length from the body. This value is specified in the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1 and informs heatsinking requirements for sustained 500 mW operation.
