Product details
Overview
JANTX1N4101D-1 from Microsemi is a 500 mW, 8.2 V ±1% tolerance Zener diode in DO-35 glass axial package, qualified to JANTX level per MIL-PRF-19500/435. It delivers stable voltage regulation with 200 Ω dynamic impedance at 250 mA test current, 0.5 µA reverse leakage at 6.3 V, and +0.070 %/°C temperature coefficient - used in precision reference and power supply feedback circuits.
For engineers reviewing the JANTX1N4101D-1 datasheet, JANTX1N4101D-1 pinout, JANTX1N4101D-1 application, or JANTX1N4101D-1 equivalent, key selection criteria include Zener voltage tolerance (1%), military reliability qualification (JANTX), thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), and DO-35 mechanical compatibility for through-hole high-reliability designs.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with metallurgical bonding ensuring low noise and radiation hardness. Its 8.2 V nominal Zener voltage is specified at 250 mA test current (IZT), and it maintains regulation across -65 °C to +175 °C junction temperature range.
The diode exhibits 200 Ω dynamic impedance (ZZT) at IZT, 0.5 µA maximum reverse current (IR) at VR = 6.3 V, and a positive temperature coefficient of +0.070 %/°C - indicating increasing VZ with rising temperature, typical for mid-voltage Zeners.
Key Specifications

FAQ
What is the Zener voltage tolerance of JANTX1N4101D-1?
JANTX1N4101D-1 has a nominal Zener voltage of 8.2 V with ±1% tolerance, confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tighter tolerance reduces calibration overhead in precision reference designs compared to standard 5% variants like JANTX1N4101-1.
Is JANTX1N4101D-1 RoHS compliant?
No - JANTX1N4101D-1 is not RoHS compliant. Per the nomenclature table on page 2, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. JANTX1N4101D-1 carries no e3 suffix and uses tin-lead plating per MIL-STD-750.
What is the maximum reverse leakage current for JANTX1N4101D-1?
The maximum reverse leakage current (IR) for JANTX1N4101D-1 is 0.5 µA at VR = 6.3 V, as specified in the Electrical Characteristics table on page 3. This low leakage supports high-impedance bias networks and minimizes error in precision analog circuits.
What package type does JANTX1N4101D-1 use?
JANTX1N4101D-1 uses the DO-35 (DO-204AH) hermetically sealed axial-leaded glass package, documented in the Mechanical and Packaging section on page 2. Dimensions are provided on page 5, with body diameter 1.42–2.29 mm and lead length 25.4–38.1 mm.
How is polarity marked on JANTX1N4101D-1?
JANTX1N4101D-1 uses a cathode band marking on the glass body to indicate polarity. As stated on page 2, the diode must be operated with the banded end positive relative to the opposite end to achieve Zener regulation - i.e., cathode is the regulated output terminal.
