Product details
Overview
JANTXV1N4128C-1/TR from Microsemi is a 60 V, 2% 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-grade power supply reference and analog signal conditioning circuits.
For engineers reviewing the JANTXV1N4128C-1/TR datasheet, JANTXV1N4128C-1/TR pinout, JANTXV1N4128C-1/TR application, or JANTXV1N4128C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status required for high-reliability design-in and obsolescence-resistant sourcing.
Technical Context
This device operates as a two-terminal reverse-biased voltage reference with a nominal Zener voltage of 60.0 V at 250 mA test current, exhibiting +0.100 %/°C temperature coefficient and 400 Ω dynamic impedance at IZT. Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
Designed for high-reliability applications, JANTXV1N4128C-1/TR meets MIL-PRF-19500/435 Class JANTXV requirements, including hermetic glass sealing, non-ESD-sensitive behavior per MIL-STD-750 Method 1020, and radiation hardness per Microsemi MicroNote 050 - all validated under controlled thermal and electrical stress conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 60.0 V ±2% at 250 mA - defines precise regulation point for feedback loops requiring tight DC reference stability |
| Power Dissipation | 500 mW at 25 °C - supports continuous operation in low-power analog references without forced cooling |
| Dynamic Impedance ZZT | 400 Ω at 250 mA - determines output voltage variation under load transients; lower than 1N4127-1 (300 Ω) but higher than 1N4126-1 (300 Ω) |
| Temperature Coefficient αVZ | +0.100 %/°C - indicates predictable positive drift with temperature, enabling compensation in wide-temperature-range designs |
| Noise Density ND | 1 µV/√Hz - ultra-low broadband noise critical for precision instrumentation and ADC reference buffers |
| Reverse Leakage IR | 10 nA max at 45.6 V - ensures minimal error current in high-impedance bias networks |
| Junction Temp Range | -65 °C to +175 °C - enables deployment in aerospace, downhole, and defense electronics without derating penalties |
Pinout & Package

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, 2% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT placement; unsuitable for through-hole prototyping or legacy board rework | Select when automated assembly and space-constrained layouts are prioritized over field-serviceability |
| JANS1N4128C-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL level) with full lot traceability and extended screening | Required for spaceflight and nuclear command systems where single-event latchup immunity and 100% lot testing are mandated | Select only when JANS-level documentation, radiation test reports, and full lot pedigree are contractually required |
Compared with JANTXV1N4128C-1/TR, 1N4128US-1 trades axial-mount flexibility for SMT compatibility, while JANS1N4128C-1 adds cost and lead time for extreme reliability assurance - making JANTXV1N4128C-1/TR the optimal balance of performance, qualification, and procurement agility for defense avionics and industrial control.

FAQ
What is the Zener voltage tolerance of JANTXV1N4128C-1/TR?
JANTXV1N4128C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number per Microsemi's nomenclature. This corresponds to a regulated output of 60.0 V ±1.2 V at 250 mA test current, verified under MIL-PRF-19500/435 JANTXV qualification testing.
Is JANTXV1N4128C-1/TR RoHS compliant?
No, JANTXV1N4128C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (suffix "e3") are available only for commercial-grade variants; JANTXV-level parts retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements.
What is the maximum Zener current IZM for JANTXV1N4128C-1/TR?
The maximum Zener current IZM for JANTXV1N4128C-1/TR is 45.6 mA, calculated from its 500 mW power rating and 60 V nominal Zener voltage (IZM = PM(AV)/VZ). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1.
Does JANTXV1N4128C-1/TR require heatsinking in typical applications?
No, JANTXV1N4128C-1/TR does not require external heatsinking in typical applications. With a thermal resistance of 250 °C/W junction-to-lead (RθJL) and 300 °C/W junction-to-ambient (RθJA), it safely dissipates 500 mW at +25 °C ambient when mounted per JEDEC standards - sufficient for most reference and biasing roles.
How is polarity marked on JANTXV1N4128C-1/TR?
JANTXV1N4128C-1/TR uses a cathode band marking on the glass body to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking is consistent across all DO-35 packaged devices in the 1N4099–1N4135 series per Microsemi mechanical specifications.
