Product details
Overview
JAN1N4113-1 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 JAN level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4113-1 datasheet, JAN1N4113-1 pinout, JAN1N4113-1 application, or JAN1N4113-1 equivalent, key selection factors include its 19.0 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.05 µA max reverse leakage at 14.5 V, and +0.090 %/°C temperature coefficient - critical for precision reference stability across wide temperature ranges.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with Zener regulation defined at IZT = 250 mA and VR = 14.5 V. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at lower voltages) and radiation hardness per MicroNote 050.
The JAN1N4113-1 exhibits a positive temperature coefficient of +0.090 %/°C, indicating increasing VZ with rising junction temperature. It is rated for TJ/TSTG = −65 °C to +175 °C and derates linearly from 500 mW at 25 °C to zero at 175 °C on a standard FR4 board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 19.0 V at 250 mA test current - defines stable regulation point for biasing or reference circuits |
| Zener Impedance | 150 Ω at 250 mA - determines output voltage variation under load current changes |
| Max Reverse Leakage | 0.05 µA at 14.5 V - ensures minimal quiescent current in standby or low-power modes |
| Temp Coefficient αVZ | +0.090 %/°C - quantifies VZ drift over temperature; critical for thermal stability in unregulated environments |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - sets maximum continuous operating power envelope |
| Noise Density | 1 µV/√Hz (typical, <6.8 V range) - enables low-noise analog references in precision instrumentation |
| Junction Temp Range | −65 °C to +175 °C - supports operation in extreme military/aerospace thermal environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N4113-1 | Same electrical specs, qualified to JANTX reliability level with extended screening | Required for programs mandating JANTX-level burn-in and life testing | Select when full JANTX screening (including 100% lot acceptance tests) is contractually required |
| 1N4113US | Same 19.0 V rating but in surface-mount DO-213AA package; no MIL qualification | Used in commercial or industrial designs where size and reflow compatibility outweigh military spec needs | Select for space-constrained PCBs where axial leads are impractical and MIL-PRF-19500 is not mandated |
Compared with JAN1N4113-1, JANTX1N4113-1 adds screening rigor without altering Zener parameters, while 1N4113US trades hermetic axial packaging for SMT fitment and waives military qualification - enabling trade-offs between reliability assurance, board area, and procurement compliance.

FAQ
What is the Zener voltage tolerance for JAN1N4113-1?
JAN1N4113-1 has a nominal Zener voltage of 19.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification 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 IZT = 250 mA.
Is JAN1N4113-1 RoHS compliant?
No, JAN1N4113-1 is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2 Rev. 1, the "e3" suffix denotes RoHS compliance and is only available on commercial-grade versions. JAN1N4113-1 carries the JAN reliability level and uses tin-lead plating per MIL-STD-750.
What is the maximum reverse leakage current for JAN1N4113-1?
The maximum reverse leakage current (IR) for JAN1N4113-1 is 0.05 µA at VR = 14.5 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 tight leakage control essential for low-power reference applications.
Can JAN1N4113-1 be used in surface-mount designs?
No, JAN1N4113-1 is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is not suitable for surface-mount assembly. For SMT equivalents, Microsemi offers the 1N4113UR-1 in DO-213AA and 1PMT4113 in DO-216 - both share the same 19.0 V rating but lack JAN qualification.
What is the thermal resistance junction-to-lead for JAN1N4113-1?
The thermal resistance junction-to-lead (RθJL) for JAN1N4113-1 is 250 °C/W when measured with 3/8 inch (10 mm) lead length from body, as stated in the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1. This value guides heatsinking decisions for continuous 500 mW operation.
