Product details
Overview
1N4113-1 from Microsemi is a 500 mW, 19.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTXV level per MIL-PRF-19500/435, with 150 Ω dynamic impedance at 250 mA test current and 0.05 µA max reverse leakage at 15.2 V. It delivers stable voltage regulation in precision reference and power supply feedback circuits across military and aerospace systems.
For engineers reviewing the 1N4113-1 datasheet, 1N4113-1 pinout, 1N4113-1 application, or 1N4113-1 equivalent, key selection criteria include its JANTXV qualification, low noise density (≤1 µV/√Hz below 6.8 V), tight thermal coefficient (+0.090 %/°C), and hermetic DO-35 packaging for high-reliability environments.
Technical Context
This Zener diode operates in reverse breakdown with cathode band indicating polarity, requiring banded end positive relative to anode for regulation. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, while RoHS-compliant plating (commercial grade only) supports solderability per MIL-STD-750 method 2026.
The device exhibits linear power derating from 500 mW at 25 °C to zero at 175 °C on typical FR4 board, with junction-to-lead thermal resistance of 250 °C/W at 10 mm lead length. Noise density is measured in 1–3 kHz band at 25 °C using 25 µA AC modulation superimposed on IZT.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | 12 V nominal, 1 W rating, DO-41 package, commercial-only, no mil-qual | Lacks JANTXV qualification and hermetic sealing; suited for industrial bench equipment | Select when cost-sensitive non-mil applications require higher power but tolerate larger footprint and lower reliability |
| 1N5247B | 19 V nominal, 500 mW, DO-35, ±5%, but only commercial grade with no MIL-PRF-19500 certification | Missing radiation hardness and extended temperature validation; limited to terrestrial embedded systems | Choose for prototyping or non-critical systems where mil-spec documentation and traceability are not required |
Compared with 1N4113-1, the 1N4742A offers higher power but lacks hermeticity and military qualification, while the 1N5247B matches voltage and package but omits JANTXV-level screening and radiation tolerance-making 1N4113-1 uniquely suitable for flight-critical voltage references.

FAQ
What is the Zener voltage tolerance for 1N4113-1?
The 1N4113-1 has a nominal Zener voltage of 19.0 V with a standard tolerance of ±5%, as defined in the JEDEC registration and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under thermal equilibrium at 25 °C with 250 mA test current, and no tighter tolerance option (e.g., 2% or 1%) is specified for this specific part number.
Is 1N4113-1 RoHS compliant?
Yes, 1N4113-1 is available in RoHS-compliant versions marked with the "e3" suffix (e.g., 1N4113-1e3), but only for commercial-grade units. Mil-qualified variants (JAN, JANTX, JANTXV, JANS) retain traditional tin-lead plating per MIL-STD-750, and RoHS compliance is explicitly restricted to commercial-grade offerings per the datasheet notes.
What is the maximum reverse leakage current for 1N4113-1?
The maximum reverse leakage current (IR) for 1N4113-1 is 0.05 µA at a reverse voltage (VR) of 15.2 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value is measured at 25 °C and reflects the device's ultra-low leakage behavior critical for high-impedance reference applications.
Does 1N4113-1 have radiation hardness specifications?
Yes, 1N4113-1 is inherently radiation hard as described in Microsemi MicroNote 050, and its JANTXV qualification per MIL-PRF-19500/435 validates performance under total ionizing dose (TID) conditions relevant to space applications. Radiation hardness is a documented feature-not inferred-and directly supports use in satellite power systems.
What is the thermal resistance from junction to lead for 1N4113-1?
The thermal resistance from junction to lead (RθJL) for 1N4113-1 is 250 °C/W when measured at 10 mm (3/8 inch) lead length from the package body, per the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1. This parameter guides heatsinking decisions for sustained 500 mW operation in lead-mounted configurations.
