Product details
Overview
JANTX1N4113-1/TR from Microsemi is a 500 mW, 19.0 V ±5% 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. It delivers 250 mA Zener test current, 150 Ω dynamic impedance at IZT, and 0.05 µA max reverse leakage at 15.2 V.
For engineers reviewing the JANTX1N4113-1/TR datasheet, JANTX1N4113-1/TR pinout, JANTX1N4113-1/TR application, or JANTX1N4113-1/TR equivalent, key selection criteria include its MIL-qualified reliability grade, low noise density (1 µV/√Hz), tight thermal coefficient (+0.090 %/°C), and hermetic DO-35 packaging for aerospace and defense power supply stabilization.
Technical Context
This device operates as a precision shunt voltage regulator with cathode-banded polarity, requiring reverse-bias operation where the banded end is positive. Its metallurgical bond construction ensures stable Zener voltage under thermal cycling and radiation exposure per MicroNote 050.
The JANTX1N4113-1/TR exhibits a defined knee region (IZK) near breakdown, supports 250 mA nominal regulation current, and maintains ≤150 Ω dynamic impedance (ZZT) at 25 °C - critical for low-noise reference stability in analog front-ends and regulated power rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4113US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair. | Select when automated placement and space-constrained layouts are prioritized over field serviceability. |
| JANS1N4113-1 | Identical electrical and mechanical specs but qualified to JANS level (highest MIL reliability tier) with full radiation testing. | Required for manned spacecraft and nuclear-hardened systems; adds cost and lead time vs. JANTX. | Select only when mission assurance mandates JANS screening and TID validation beyond JANTX requirements. |
Compared with JANTX1N4113-1/TR, the 1N4113US-1 enables miniaturization but sacrifices mechanical robustness and hand-soldering compatibility, while JANS1N4113-1 adds radiation tolerance and extended screening at higher cost and longer procurement cycles - making JANTX1N4113-1/TR the optimal balance for high-reliability avionics without extreme radiation exposure.

FAQ
What is the Zener voltage tolerance of JANTX1N4113-1/TR?
JANTX1N4113-1/TR has a nominal Zener voltage of 19.0 V with a standard tolerance of ±5%, as specified in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and is consistent across all JANTX-grade units in the 1N4099–1N4135 series.
Is JANTX1N4113-1/TR RoHS compliant?
No, JANTX1N4113-1/TR is not RoHS compliant. Per the nomenclature guide in the datasheet, RoHS compliance (e3 suffix) is available only on commercial-grade versions of this series. The JANTX prefix indicates military-grade qualification under MIL-PRF-19500/435, which retains tin-lead plating for enhanced solderability and reliability in high-stress environments.
What is the maximum reverse leakage current for JANTX1N4113-1/TR?
The maximum reverse leakage current (IR) for JANTX1N4113-1/TR is 0.05 µA at VR = 15.2 V, as confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This value is measured at 25 °C and reflects the device's tight leakage specification for low-power reference applications.
Does JANTX1N4113-1/TR have radiation hardness certification?
Yes, JANTX1N4113-1/TR is inherently radiation hard per Microsemi MicroNote 050, as stated in the Applications/Benefits section of the datasheet. While not individually tested to specific TID levels like JANS-grade parts, its metallurgically bonded construction and DO-35 hermetic package provide proven resilience in low-to-moderate radiation environments typical of LEO satellites and avionics.
What is the thermal resistance junction-to-lead for JANTX1N4113-1/TR?
The thermal resistance junction-to-lead (RθJL) for JANTX1N4113-1/TR is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the body, as specified in the Maximum Ratings table on page 1 of the T4-LDS-0245-2 datasheet. This value supports thermal modeling for lead-mounted heatsinking in high-reliability power supply designs.
