Product details
Overview
JANTXV1N4113D-1 from Microsemi is a 19.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4113D-1 datasheet, JANTXV1N4113D-1 pinout, JANTXV1N4113D-1 application, or JANTXV1N4113D-1 equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and JANTXV-level qualification for extended temperature operation.
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, exhibiting low dynamic impedance (150 Ω) and minimal noise density (1 µV/√Hz) - critical for low-noise reference circuits in analog instrumentation and telemetry systems.
Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range, with thermal resistance junction-to-lead of 250 °C/W and linear derating from 500 mW at 25 °C to zero at 175 °C under ambient conditions on standard FR4 PCBs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4113US-1 | Same electrical specs but in DO-213AA surface-mount package | Requires PCB rework for SMT assembly; no axial lead mounting option | Select when board space constraints mandate surface-mount integration without lead-forming. |
| 1N4113D-1 (commercial grade) | Identical Zener parameters but only commercial qualification (no MIL-PRF-19500 screening) | Not suitable for aerospace/defense programs requiring JANTXV traceability and screening | Select only for cost-sensitive industrial prototypes where MIL-spec is not mandated. |
Compared with JANTXV1N4113D-1, the JANTXV1N4113US-1 offers identical regulation performance in a space-saving SMT form factor, while the 1N4113D-1 provides identical electrical behavior without military screening - making the former ideal for miniaturized avionics, and the latter appropriate for non-mission-critical development platforms.

FAQ
What is the Zener voltage tolerance of JANTXV1N4113D-1?
JANTXV1N4113D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This tolerance applies to the nominal 19.0 V Zener voltage measured at 250 mA test current and 25 °C ambient temperature, and is verified during JANTXV-level qualification testing per MIL-PRF-19500/435.
Is JANTXV1N4113D-1 RoHS compliant?
No, JANTXV1N4113D-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTXV1N4113D-1, which retain traditional tin-lead plating to meet military solderability and reliability requirements.
What is the maximum Zener current IZM for JANTXV1N4113D-1?
The maximum Zener current IZM for JANTXV1N4113D-1 is 40 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value corresponds to the current at which the device reaches its rated 500 mW power dissipation at 19.0 V, assuming ideal thermal conditions and no derating.
How does the temperature coefficient affect JANTXV1N4113D-1 in real-world operation?
JANTXV1N4113D-1 has a temperature coefficient of +0.090 %/°C, meaning its Zener voltage increases by approximately 17.1 mV per °C rise above 25 °C. Over a -55 °C to +125 °C range, this results in a total shift of ±13.6 V, but actual variation is bounded by the 1% initial tolerance and nonlinear effects - confirmed in Microsemi's characterization data.
Can JANTXV1N4113D-1 be used in surface-mount designs?
JANTXV1N4113D-1 itself is axial-leaded in DO-35 package and not suitable for direct SMT placement. However, Microsemi offers the functionally identical JANTXV1N4113US-1 in DO-213AA surface-mount package, sharing the same 19.0 V ±1% Zener voltage, 150 Ω dynamic impedance, and JANTXV qualification - enabling drop-in replacement in SMT layouts.
