Product details
Overview
JANTX1N4113C-1/TR from Microsemi is a 500 mW, 19.0 V ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4113C-1/TR datasheet, JANTX1N4113C-1/TR pinout, JANTX1N4113C-1/TR application, or JANTX1N4113C-1/TR equivalent, this part delivers precise 19.0 V regulation at 250 mA test current, low 150 Ω dynamic impedance, <0.05 µA reverse leakage at 14.5 V, and radiation-hardened performance in hermetically sealed glass construction.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgical bond ensures stable junction behavior under thermal cycling and mechanical stress.
It exhibits a +0.090 %/°C temperature coefficient and 1 µV/√Hz noise density at lower voltages-critical for precision reference circuits where drift and noise directly impact ADC accuracy and analog signal integrity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4113C-1 | JANS-level qualification (higher screening vs. JANTX); identical electrical specs and DO-35 package | Required for space-grade programs with full MIL-PRF-19500/435 JANS compliance | Select when mission-critical radiation tolerance and burn-in testing are mandated beyond JANTX requirements |
| 1N4113C-1TR | Commercial-grade (non-mil) version; same 19.0 V ±2%, DO-35, but no MIL-PRF-19500 qualification | Suitable for industrial test equipment or non-safety-critical instrumentation where cost and lead time are primary constraints | Choose for prototyping or volume production where military screening is unnecessary and RoHS compliance is required |
Compared with JANS1N4113C-1, the JANTX1N4113C-1/TR offers reduced screening rigor but retains full JANTX reliability for airborne systems; versus 1N4113C-1TR, it guarantees traceable mil-spec conformance, thermal stability, and radiation hardness-critical for deployed defense hardware.

FAQ
What is the Zener voltage and tolerance of JANTX1N4113C-1/TR?
JANTX1N4113C-1/TR has a nominal Zener voltage of 19.0 V with a ±2% tolerance, measured at 250 mA test current and 25 °C ambient. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0245-2 Rev. 1, and applies strictly to the JANTX1N4113C-1/TR variant with 'C' suffix denoting 2% tolerance per the nomenclature guide.
Is JANTX1N4113C-1/TR RoHS compliant?
No, JANTX1N4113C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with 'e3' suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS levels. The 'TR' suffix indicates tape-and-reel packaging but does not imply RoHS compliance.
What is the maximum reverse leakage current for JANTX1N4113C-1/TR?
The maximum reverse leakage current (IR) for JANTX1N4113C-1/TR is 0.05 µA at 14.5 V, as specified in the Electrical Characteristics table on page 3 of the datasheet. This value is guaranteed across the full military temperature range and reflects the tight leakage control enabled by metallurgical bonding.
What package type does JANTX1N4113C-1/TR use?
JANTX1N4113C-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Dimensions are fully detailed on page 5 of the datasheet, with body diameter 1.42–2.29 mm and overall length 3.56–5.08 mm. The 'TR' suffix confirms tape-and-reel packaging format.
How is polarity marked on JANTX1N4113C-1/TR?
Polarity is marked by a single black cathode band on the glass body of JANTX1N4113C-1/TR. The banded end is the cathode and must be held positive relative to the unbanded (anode) end for proper Zener regulation. This marking convention is explicitly stated in the Mechanical and Packaging section on page 2 of the datasheet.
