Product details
Overview
JANTXV1N4102D-1 from Microsemi is a 500 mW, 8.7 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation. It delivers 250 mA Zener test current, 200 Ω dynamic impedance at IZT, and +0.075 %/°C temperature coefficient, used in precision reference and power supply feedback circuits.
For engineers reviewing the JANTXV1N4102D-1 datasheet, JANTXV1N4102D-1 pinout, JANTXV1N4102D-1 application, or JANTXV1N4102D-1 equivalent, key selection criteria include its 1% Zener voltage tolerance, JANTXV reliability qualification, DO-35 thermal resistance (RθJL = 250 °C/W), low noise density (1 µV/√Hz), and operation across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures stable Zener voltage under thermal cycling and radiation exposure, supporting MIL-STD-750 method 1020 ESD immunity and inherent radiation hardness per MicroNote 050.
The JANTXV1N4102D-1 exhibits a positive temperature coefficient (+0.075 %/°C), enabling predictable voltage drift over temperature. Its 200 Ω dynamic impedance at 250 mA test current and 0.5 W power rating-derated linearly from 50 °C ambient-support stable regulation in low-noise analog references and feedback loops requiring tight voltage accuracy.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4102US | Same 8.7 V ±1% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space constraints mandate surface-mount and thermal pad layout supports RθJA derating |
| 1N4102UR-1 | Commercial-grade (non-mil-qualified), same DO-35 package and 8.7 V ±1% spec, RoHS-compliant | Lacks JANTXV reliability screening; not rated for radiation or extended temperature extremes | Select for cost-sensitive industrial controls where MIL-spec is unnecessary and RoHS compliance is mandatory |
Compared with JANTXV1N4102D-1, JANTXV1N4102US offers identical electrical performance in a space-saving SMT form factor but sacrifices mechanical robustness and lead-form flexibility, while 1N4102UR-1 reduces cost and meets environmental directives at the expense of guaranteed high-reliability operation.

FAQ
What is the Zener voltage tolerance and test current for JANTXV1N4102D-1?
JANTXV1N4102D-1 has a nominal Zener voltage of 8.7 V with ±1% tolerance, verified at a Zener test current (IZT) of 250 mA. This tight tolerance eliminates the need for external trimming in precision reference designs, and the specified test current ensures consistent regulation performance under typical operating loads.
Is JANTXV1N4102D-1 qualified to military specifications?
Yes, JANTXV1N4102D-1 is fully qualified to MIL-PRF-19500/435 at the JANTXV reliability level, including screening for thermal shock, vibration, and long-term life testing. This qualification confirms its suitability for high-integrity applications such as flight control systems and secure communications hardware where failure is not acceptable.
What is the maximum junction temperature and thermal resistance of JANTXV1N4102D-1?
JANTXV1N4102D-1 supports a junction temperature range of –65 °C to +175 °C. Its thermal resistance junction-to-lead (RθJL) is 250 °C/W when mounted with 3/8″ (10 mm) lead length from the body, enabling reliable heat dissipation in high-temperature environments without forced cooling.
Does JANTXV1N4102D-1 have low noise characteristics suitable for analog references?
Yes, JANTXV1N4102D-1 delivers a noise density of 1 µV/√Hz at its 250 mA test current, making it appropriate for low-noise analog references. This performance is confirmed per Microsemi's noise measurement methodology using a 1 kHz–3 kHz bandpass filter and supports high-fidelity signal conditioning in precision instrumentation.
How is polarity marked on the JANTXV1N4102D-1 package?
JANTXV1N4102D-1 uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode to operate in Zener breakdown mode. This marking complies with JEDEC DO-35 standards and is visible on the hermetically sealed glass body for unambiguous orientation during manual or automated placement.
