Product details
Overview
JANTXV1N4113D-1/TR from Microsemi is a 19.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to JANTXV level per MIL-PRF-19500/435, used for precision voltage regulation in military and aerospace power supply reference circuits.
For engineers reviewing the JANTXV1N4113D-1/TR datasheet, JANTXV1N4113D-1/TR pinout, JANTXV1N4113D-1/TR application, or JANTXV1N4113D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification details required for high-reliability analog design and radiation-hardened system validation.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 19.0 V at 250 mA test current (IZT), exhibiting a +0.090 %/°C temperature coefficient and 150 Ω dynamic impedance (ZZT) at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling.
It delivers low noise density of 1 μV/√Hz at 19.0 V, supports operation from –65 °C to +175 °C junction temperature, and maintains ≤0.05 µA reverse leakage (IR) at VR = 14.5 V - meeting stringent requirements for low-drift analog references in avionics and space-grade instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 19.0 V ±1% at 250 mA - enables precise 19 V reference generation with minimal calibration drift |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4113US-1TR | Same 19.0 V, 1% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when automated assembly, board space constraints, or reflow compatibility outweigh leaded mounting needs |
| JANS1N4113D-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL-PRF-19500 level) with extended screening | Required for Class-S spaceflight or nuclear command systems where JANTXV is insufficient for mission assurance | Select only when JANS-level radiation testing, burn-in, and lot acceptance testing are mandated by program requirements |

FAQ
What is the Zener voltage tolerance of JANTXV1N4113D-1/TR?
JANTXV1N4113D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per MIL-PRF-19500/435 nomenclature. This means its measured VZ at 250 mA test current falls within 18.81 V to 19.19 V at 25 °C, enabling high-accuracy reference design without post-production trimming.
Is JANTXV1N4113D-1/TR RoHS compliant?
No, JANTXV1N4113D-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4113D-1e3); JANTXV-level parts retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under military thermal cycling requirements.
What is the maximum operating temperature for JANTXV1N4113D-1/TR?
JANTXV1N4113D-1/TR has a junction and storage temperature range of –65 °C to +175 °C. Its rated 500 mW power dissipation linearly derates to zero at +175 °C, supporting operation in extreme environments such as jet engine bays or spacecraft thermal vacuum chambers.
Does JANTXV1N4113D-1/TR require heatsinking?
JANTXV1N4113D-1/TR does not require external heatsinking at ambient temperatures ≤50 °C due to its 300 °C/W junction-to-ambient thermal resistance on FR4 board. However, at higher ambient temperatures or sustained >300 mW dissipation, thermal relief via copper pour or lead length optimization is recommended per Figure 2 derating curve.
How is polarity marked on JANTXV1N4113D-1/TR?
JANTXV1N4113D-1/TR uses a cathode band - a single opaque ring near one end of the DO-35 glass body - to indicate the cathode terminal. For proper Zener regulation, the banded end must be biased positively relative to the anode, i.e., reverse-biased in circuit operation.
