It delivers stable regulation at 250 mA test current with 100 Ω dynamic impedance, 0.05 µA reverse leakage at 13.0 V, and +0.090 %/°C temperature coefficient.
For engineers reviewing the JANTX1N4111-1/TR datasheet, JANTX1N4111-1/TR pinout, JANTX1N4111-1/TR application, or JANTX1N4111-1/TR equivalent, key selection criteria include Zener voltage tolerance, MIL-qualified reliability level, thermal resistance (250 °C/W junction-to-lead), noise density (1 µV/√Hz), and DO-35 mechanical compatibility in space-constrained analog reference and power-supply feedback circuits.
Technical Context
This device operates as a precision shunt voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgically bonded construction ensures stable long-term Zener voltage and low parametric drift under thermal cycling and radiation exposure.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4111US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used; verify pad layout matches Microsemi DO-213AA footprint |
| JANTXV1N4111-1 | Identical electrical specs with enhanced JANTXV-level screening (100% burn-in, extended environmental testing) | Required for mission-critical avionics where failure modes demand higher confidence than JANTX level | Choose when system safety integrity level (ASIL-D or DAL-A) mandates extended reliability validation beyond JANTX |
Compared with JANTX1N4111-1/TR, the 1N4111US-1 offers identical regulation performance in a smaller surface-mount form factor but sacrifices mechanical robustness and hand-solderability, while the JANTXV1N4111-1 adds rigorous screening for zero-defect operation in life-critical systems - neither is pin-compatible due to differing packages or qualification scope.

FAQ
What is the Zener voltage tolerance for JANTX1N4111-1/TR?
JANTX1N4111-1/TR has a nominal Zener voltage of 17.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies at IZT = 250 mA and TA = 25 °C, and is maintained across the full qualified temperature range via JANTX-level screening.
Does JANTX1N4111-1/TR require external heat sinking?
JANTX1N4111-1/TR does not require external heat sinking under typical conditions: its thermal resistance junction-to-lead is 250 °C/W with 3/8″ (10 mm) lead length, and it is rated for 500 mW at 25 °C lead temperature. Derating begins linearly at 50 °C, reaching zero dissipation at 175 °C - sufficient for most through-hole applications with adequate PCB copper area.
Is JANTX1N4111-1/TR RoHS compliant?
No, JANTX1N4111-1/TR is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance, which is available only on commercial-grade versions. JANTX-level parts like JANTX1N4111-1/TR retain tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS under EU Directive Annex III.
What is the maximum reverse leakage current for JANTX1N4111-1/TR?
The maximum reverse leakage current for JANTX1N4111-1/TR is 0.05 µA at VR = 13.0 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value is measured at 25 °C and reflects the device's ability to minimize error current in high-impedance reference divider networks.
Can JANTX1N4111-1/TR be used in radiation-exposed environments?
Yes, JANTX1N4111-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded DO-35 structure and silicon process yield proven tolerance to total ionizing dose (TID) up to 100 krad(Si), making it suitable for satellite, nuclear, and high-altitude avionics applications where radiation-induced parameter shift must be minimized.
