Product details
Overview
JANTX1N4113-1 from Microsemi is a 500 mW, 19.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability regulation. It delivers 14.5 mA maximum Zener current at 25 °C, exhibits 150 Ω dynamic impedance at 250 mA test current, and maintains stable voltage regulation across -65 °C to +175 °C junction temperature range in aerospace power conditioning circuits.
For engineers reviewing the JANTX1N4113-1 datasheet, JANTX1N4113-1 pinout, JANTX1N4113-1 application, or JANTX1N4113-1 equivalent, key selection criteria include its 19.0 V nominal Zener voltage, 150 Ω ZZT at IZT = 250 mA, 0.05 µA reverse leakage at VR = 15.2 V, JANTX-level military qualification, and DO-35 hermetic glass package suitability for radiation-hardened analog references.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, with Zener voltage specified at 250 mA test current (IZT) and characterized by low noise density (1 µV/√Hz typical at lower voltages). Its metallurgical bond construction ensures mechanical stability under thermal cycling and shock, critical for MIL-qualified applications.
The JANTX1N4113-1 exhibits a +0.090 %/°C temperature coefficient of Zener voltage and supports linear power derating from 500 mW at 25 °C to zero at 175 °C ambient, with thermal resistance junction-to-lead rated at 250 °C/W for 10 mm lead length.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4113US (Microchip) | Same 19.0 V nominal Zener, but in surface-mount DO-213AA package; no MIL qualification | Lacks JANTX-level screening and radiation tolerance; suited for commercial industrial designs only | Select when board space constraints require SMT mounting and military reliability is not required |
| JAN1N4113-1 (Microsemi) | Identical electrical specs and DO-35 package, but qualified only to JAN level (lower screening severity than JANTX) | Approved for less demanding military programs; reduced burn-in and life-test requirements vs. JANTX | Select when full JANTX qualification is unnecessary and cost optimization is prioritized |
Compared with JANTX1N4113-1, the 1N4113US offers footprint reduction at the expense of MIL qualification and radiation hardness, while JAN1N4113-1 provides identical performance with relaxed screening-enabling trade-offs between reliability assurance, cost, and form factor.

FAQ
What is the nominal Zener voltage and tolerance of JANTX1N4113-1?
JANTX1N4113-1 has a nominal Zener voltage of 19.0 V with ±5% tolerance at IZT = 250 mA and 25 °C. This value is measured under thermal equilibrium in still air and reflects the standard JEDEC tolerance for this part number series. The device maintains regulation within this band across its full operating temperature range of -65 °C to +175 °C.
Is JANTX1N4113-1 suitable for space applications?
Yes, JANTX1N4113-1 is inherently radiation hard per Microsemi MicroNote 050 and qualified to MIL-PRF-19500/435 JANTX level, making it suitable for low-dose space applications such as LEO satellite sensor biasing. Its hermetic DO-35 package and metallurgical bond construction further enhance survivability in vacuum and thermal cycling environments.
What is the maximum Zener current (IZM) for JANTX1N4113-1?
The maximum Zener current (IZM) for JANTX1N4113-1 is 40 mA at 25 °C ambient, derived from its 500 mW power rating and 19.0 V nominal Zener voltage. This value assumes thermal equilibrium and linear derating applies above 50 °C lead temperature, reaching zero dissipation at 175 °C.
Does JANTX1N4113-1 have RoHS compliance?
No, JANTX1N4113-1 is not RoHS compliant. RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants per the datasheet; JANTX-level parts retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements.
How does the temperature coefficient affect JANTX1N4113-1 in precision circuits?
JANTX1N4113-1 has a temperature coefficient (αVZ) of +0.090 %/°C, meaning its Zener voltage increases by approximately 17.1 mV per °C rise at 19.0 V. In precision circuits, this drift must be compensated via circuit topology or calibration-especially over wide temperature ranges like -55 °C to +125 °C in avionics.
