Product details
Overview
JANTXV1N4103D-1 from Microsemi is a 500 mW, 9.1 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability military and aerospace voltage regulation. It delivers 250 mA Zener test current, 200 Ω dynamic impedance at IZT, and 0.5 µA max reverse leakage at 7.0 V.
For engineers reviewing the JANTXV1N4103D-1 datasheet, JANTXV1N4103D-1 pinout, JANTXV1N4103D-1 application, or JANTXV1N4103D-1 equivalent, key selection criteria include its 1% voltage tolerance, JANTXV radiation-hardened qualification, low noise density (1 µV/√Hz), hermetic DO-35 packaging, and thermal resistance of 250 °C/W junction-to-lead.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 9.1 V at 250 mA test current. Its metallurgical bond construction ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range and supports operation under high-reliability environmental stress per MIL-PRF-19500/435.
The diode exhibits 200 Ω dynamic impedance at IZT, 0.5 µA reverse leakage at VR = 7.0 V, and a positive temperature coefficient of +0.080 %/°C - enabling predictable voltage drift compensation in regulated power supplies and reference circuits requiring long-term stability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4103US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair. | Select when automated assembly and space-constrained layouts are prioritized over field serviceability. |
| JAN1N4103D-1 | Identical electrical and mechanical specs but qualified only to JAN level (less stringent screening than JANTXV). | Lacks JANTXV-level burn-in, life test, and radiation assurance data required for mission-critical platforms. | Select only for non-safety-critical commercial/military hybrids where full JANTXV screening is not mandated. |
Compared with JANTXV1N4103D-1, the 1N4103US-1 offers identical regulation performance in a smaller footprint but eliminates axial-lead flexibility, while the JAN1N4103D-1 reduces cost and lead time at the expense of verified high-reliability screening data needed for flight hardware.

FAQ
What is the Zener voltage tolerance of JANTXV1N4103D-1?
JANTXV1N4103D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where VZ = 9.1 V at IZT = 250 mA with 1% tolerance specified for the 1N4103-1 variant, and JANTXV qualification applies identically to this tolerance grade.
Is JANTXV1N4103D-1 RoHS compliant?
No, JANTXV1N4103D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS under military procurement waivers.
What is the maximum Zener current IZM for JANTXV1N4103D-1?
The maximum Zener current IZM for JANTXV1N4103D-1 is 40 mA, as listed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value corresponds to the 500 mW power rating derated at elevated temperatures and assumes operation within the specified thermal limits.
Does JANTXV1N4103D-1 have radiation hardness certification?
Yes, JANTXV1N4103D-1 is inherently radiation hard per Microsemi MicroNote 050, as stated in the Applications/Benefits section of the datasheet. While not individually tested to specific rad levels, its metallurgically bonded DO-35 construction and JANTXV qualification provide documented resilience to total ionizing dose (TID) and single-event effects typical of space and nuclear environments.
What is the thermal resistance junction-to-lead (RθJL) for JANTXV1N4103D-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4103D-1 is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the body, as specified in the Maximum Ratings table on page 1 of T4-LDS-0245-2 Rev. 1. This value is critical for calculating safe operating area under pulsed or continuous power conditions.
