Product details
Overview
JANTXV1N4100D-1/TR from Microsemi is a 1% tolerance, 7.5 V, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4100D-1/TR datasheet, JANTXV1N4100D-1/TR pinout, JANTXV1N4100D-1/TR application, or JANTXV1N4100D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (200 Ω at 250 mA), noise density (40 µV/√Hz), temperature coefficient (+0.065 %/°C), and JANTXV-level qualification for extended temperature operation (–65 °C to +175 °C).
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction enabling stable breakdown characteristics across wide current (250 mA test point) and temperature ranges. Its low noise density and tight 1% voltage tolerance support reference-grade applications where stability under thermal stress and low AC perturbation are critical.
The DO-35 hermetically sealed glass package provides radiation hardness per MicroNote 050 and ESD immunity per MIL-STD-750 Method 1020. Thermal resistance junction-to-lead is 250 °C/W at 10 mm lead length, supporting reliable power dissipation up to 500 mW with linear derating above 50 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4100US-1 | Same 7.5 V, 1% tolerance, but in surface-mount DO-213AA package; no JANTXV qualification. | Limited to commercial-grade PCB assembly; unsuitable for through-hole legacy designs or MIL-qualified programs. | Select when board space constraints require SMT and radiation/temperature specs are relaxed. |
| JANTXV1N4101D-1/TR | 8.2 V nominal Zener voltage; identical JANTXV qualification, DO-35 package, and 1% tolerance. | Used where higher reference voltage is required in same footprint; not interchangeable without circuit recalibration. | Choose only if system design requires 8.2 V reference; verify feedback divider ratio compatibility. |
Compared with JANTXV1N4100D-1/TR, the 1N4100US-1 trades military qualification and axial mounting for SMT compatibility, while JANTXV1N4101D-1/TR maintains full drop-in mechanical and reliability equivalence but shifts regulation voltage-requiring explicit redesign of voltage-setting networks.

FAQ
What is the Zener voltage tolerance of JANTXV1N4100D-1/TR?
JANTXV1N4100D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where VZ = 7.5 V at IZT = 250 mA. The tighter tolerance supports high-accuracy reference applications without post-manufacturing calibration.
Is JANTXV1N4100D-1/TR qualified to JANTXV reliability level?
Yes, JANTXV1N4100D-1/TR is explicitly qualified to the JANTXV level per MIL-PRF-19500/435, as stated in the DESCRIPTION section on page 1 and confirmed in the PART NOMENCLATURE table. This qualification includes extended temperature screening, burn-in, and lot acceptance testing for high-reliability deployment.
What package type does JANTXV1N4100D-1/TR use?
JANTXV1N4100D-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Mechanical dimensions and contour specifications are provided on page 5 of T4-LDS-0245-2 Rev. 1, confirming standard lead spacing and body diameter compliance.
What is the maximum power dissipation of JANTXV1N4100D-1/TR?
JANTXV1N4100D-1/TR has a rated average power dissipation of 0.5 W (500 mW) at 25 °C case temperature. Per Note 2 on page 2, this rating linearly derates to zero at 175 °C, with full derating beginning at 50 °C per the Power Derating Curve in Figure 2.
Does JANTXV1N4100D-1/TR have radiation hardness?
Yes, JANTXV1N4100D-1/TR is inherently radiation hard as described in Microsemi MicroNote 050, referenced in the APPLICATIONS / BENEFITS section on page 1. Its metallurgically bonded construction and hermetic DO-35 package contribute to tolerance against total ionizing dose (TID) and single-event effects in space and nuclear environments.
