For engineers reviewing the JAN1N4113D-1/TR datasheet, JAN1N4113D-1/TR pinout, JAN1N4113D-1/TR application, or JAN1N4113D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), junction temperature range (–65 °C to +175 °C), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), and military qualification level.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 19.0 V at 250 mA test current. Its metallurgical bond construction ensures stable breakdown characteristics and low long-term drift under thermal cycling and radiation exposure.
The diode exhibits a positive temperature coefficient of +0.090 %/°C and maximum reverse leakage of 0.05 µA at 14.5 V, enabling stable regulation across wide temperature ranges without external compensation circuits.

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 re-layout for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated assembly and board space reduction are priorities over manual serviceability |
| JANTXV1N4113D-1 | Identical Zener parameters and package, but qualified to JANTXV (not JANS) per MIL-PRF-19500/435 | Lower screening level: excludes radiation testing and extended life testing required for spaceflight | Select for high-reliability ground-based military systems where full JANS qualification is not mandated |
Compared with JAN1N4113D-1/TR, 1N4113US-1 offers identical regulation performance in a smaller footprint but requires SMT infrastructure, while JANTXV1N4113D-1 provides cost savings for non-space applications without sacrificing voltage accuracy or thermal stability.

FAQ
What is the Zener voltage tolerance for JAN1N4113D-1/TR?
JAN1N4113D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This tight tolerance is achieved through post-manufacturing screening and is specified at 250 mA test current and 25 °C ambient. The 19.0 V nominal value remains stable across its full operating temperature range due to its +0.090 %/°C temperature coefficient.
Is JAN1N4113D-1/TR suitable for space applications?
Yes, JAN1N4113D-1/TR is qualified to JANS level per MIL-PRF-19500/435, making it suitable for space applications. It undergoes rigorous screening including radiation hardness assurance per Microsemi MicroNote 050, extended life testing, and hermeticity validation. Its DO-35 glass package and metallurgical bond construction meet Class S requirements for low outgassing and thermal shock resistance.
What is the maximum reverse leakage current for JAN1N4113D-1/TR?
The maximum reverse leakage current for JAN1N4113D-1/TR is 0.05 µA at a reverse voltage of 14.5 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports use in battery-powered systems and high-impedance sensing circuits where standby current must be minimized.
Does JAN1N4113D-1/TR require derating above 25 °C?
Yes, JAN1N4113D-1/TR must be derated linearly starting at 50 °C lead temperature, reaching zero power dissipation at 175 °C. On a typical FR4 PCB with 1 oz copper, derating begins at 25 °C ambient and follows the curve in Figure 2 of the datasheet. At 100 °C ambient, the allowable power drops to approximately 250 mW.
What does the "TR" suffix indicate in JAN1N4113D-1/TR?
The "TR" suffix in JAN1N4113D-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated pick-and-place assembly. This version contains the same JANS-qualified die and DO-35 package as the bulk version, with no electrical or reliability differences-only packaging format changes to support high-volume manufacturing workflows.
