Product details
Overview
JANTX1N4100C-1/TR from Microsemi is a 500 mW, 7.5 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 200 Ω maximum dynamic impedance at 250 mA test current, and 5.7 mA maximum Zener current for precision voltage reference in military-grade power supply regulation.
For engineers reviewing the JANTX1N4100C-1/TR datasheet, JANTX1N4100C-1/TR pinout, JANTX1N4100C-1/TR application, or JANTX1N4100C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), RoHS compliance status (e3 suffix not present), and MIL-qualified reliability level (JANTX).
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction for high-reliability operation across -65 °C to +175 °C junction temperature range. It delivers stable 7.5 V regulation at 250 mA test current with 200 Ω dynamic impedance and exhibits +0.065 %/°C temperature coefficient above 7.5 V.
Designed for use in fixed-voltage regulation and reference circuits, it supports low-noise performance (1 µV/√Hz) and minimal capacitance (typical <2 pF), enabling stable operation in analog signal conditioning and precision power monitoring where ESD immunity and radiation hardness are required.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4100US-1 | Same 7.5 V nominal Zener voltage and ±2% tolerance, but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair | Select when automated assembly and space-constrained layouts are prioritized over manual serviceability |
| JAN1N4100C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (lower screening than JANTX) | Lacks extended life test and burn-in requirements of JANTX; not approved for Class H or Class K programs | Select only for non-mission-critical commercial-aerospace subsystems where cost reduction outweighs reliability margin |
Compared with JANTX1N4100C-1/TR, 1N4100US-1 offers footprint reduction at the expense of mechanical robustness and hand-soldering compatibility, while JAN1N4100C-1 reduces procurement cost but sacrifices MIL-PRF-19500/435 JANTX-level screening rigor required for flight hardware.

FAQ
What is the Zener voltage tolerance of JANTX1N4100C-1/TR?
JANTX1N4100C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where 1N4100-1 shows nominal 7.5 V at IZT = 250 mA, and the "C" designation maps to 2% tolerance in the PART NOMENCLATURE section on page 2. The tolerance applies across the full operating temperature range.
Is JANTX1N4100C-1/TR RoHS compliant?
No, JANTX1N4100C-1/TR is not RoHS compliant. Per the PART NOMENCLATURE table on page 2 of T4-LDS-0245-2 Rev. 1, RoHS compliance requires the "e3" suffix, which is absent in JANTX1N4100C-1/TR. The datasheet explicitly states that RoHS-compliant versions are available "on commercial grade only", and JANTX denotes a military-qualified product line where leaded terminations are retained for solderability and reliability in high-reliability applications.
What is the maximum Zener current rating for JANTX1N4100C-1/TR?
The maximum Zener current (IZM) for JANTX1N4100C-1/TR is 40 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1 under the row for 1N4100-1. This value represents the absolute maximum dc current the device can sustain continuously at 25 °C ambient while remaining within its 500 mW power limit and thermal constraints.
Does JANTX1N4100C-1/TR have radiation hardness certification?
Yes, JANTX1N4100C-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050 cited in the APPLICATIONS / BENEFITS section on page 1 of T4-LDS-0245-2 Rev. 1. Its metallurgically bonded glass construction and MIL-PRF-19500/435 qualification support operation in total ionizing dose (TID) environments typical of low-earth orbit and nuclear instrumentation applications.
What does the "TR" suffix indicate in JANTX1N4100C-1/TR?
The "TR" suffix in JANTX1N4100C-1/TR indicates tape-and-reel packaging per EIA-296 standard, as stated in the MECHANICAL and PACKAGING section on page 2 of T4-LDS-0245-2 Rev. 1. This format supports automated pick-and-place assembly and is distinct from bulk or ammo-pack options; the "TR" does not affect electrical or reliability specifications of the JANTX1N4100C-1/TR device itself.
