Product details
Overview
JANTX1N4100D-1/TR from Microsemi is a 500 mW, 7.5 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4100D-1/TR datasheet, JANTX1N4100D-1/TR pinout, JANTX1N4100D-1/TR application, or JANTX1N4100D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision reference and overvoltage protection design.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 7.5 V at 250 mA test current, exhibiting +0.065 %/°C temperature coefficient and 200 Ω dynamic impedance at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for hermetic axial-leaded mounting, JANTX1N4100D-1/TR maintains ≤1.0 µA reverse leakage at VR = 5.7 V and delivers 40 µV/√Hz noise density at ≥6.8 V - confirming suitability for low-noise analog references and regulated bias networks in harsh-environment electronics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4100D-1 | Higher qualification level (JANTXV vs JANTX); tighter screening, extended temperature testing, and enhanced lot traceability. | Required for mission-critical avionics where burn-in and radiation testing are mandated beyond JANTX. | Select JANTXV1N4100D-1 only if system-level qualification requires JANTXV-level screening per MIL-PRF-19500/435. |
| 1N4100US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads; RoHS-compliant matte-tin plating. | Suitable for automated SMT assembly and space-constrained PCBs where through-hole mounting is impractical. | Choose 1N4100US-1 when board real estate or reflow compatibility outweighs legacy axial-lead requirements. |
Compared with JANTX1N4100D-1/TR, JANTXV1N4100D-1 offers higher reliability assurance for life-critical functions, while 1N4100US-1 enables modern SMT integration - neither is pin-compatible due to differing packages, and both require layout adaptation.

FAQ
What is the Zener voltage tolerance of JANTX1N4100D-1/TR?
JANTX1N4100D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This corresponds to a nominal 7.5 V rating with actual VZ ranging from 7.425 V to 7.575 V at 250 mA test current and 25 °C ambient - critical for applications demanding tight regulation without post-manufacture trimming.
Is JANTX1N4100D-1/TR RoHS compliant?
No, JANTX1N4100D-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4100D-1e3); military-qualified parts like JANTX1N4100D-1/TR retain tin-lead plating per MIL-STD-750 and are exempt from RoHS restrictions to maintain solderability and reliability in high-reliability assemblies.
What does the "TR" suffix mean in JANTX1N4100D-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTX1N4100D-1/TR is supplied in reels rather than bulk or ammo-pack formats - essential for high-volume production of military-grade boards where traceability and handling consistency are required.
How is the polarity marked on JANTX1N4100D-1/TR?
JANTX1N4100D-1/TR uses a cathode band marking on the glass body: the banded end is the cathode and must be held positive relative to the anode to achieve Zener regulation. This polarity is consistent across all DO-35 Zeners in the 1N4099–1N4135 series and is verified per MIL-PRF-19500/435 mechanical inspection criteria.
What is the maximum Zener current IZM for JANTX1N4100D-1/TR?
The maximum Zener current IZM for JANTX1N4100D-1/TR is 40 mA at 25 °C ambient, derived from its 500 mW power rating and 7.5 V nominal Zener voltage (IZM = PM(AV)/VZ ≈ 66.7 mA, but datasheet specifies 40 mA to ensure safe margin under thermal derating). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2.
