Product details
Overview
JAN1N4101-1 from Microsemi is a 500 mW, 8.2 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 applications. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance, low noise density (1 µV/√Hz), and operates across –65 °C to +175 °C junction temperature.
For engineers reviewing the JAN1N4101-1 datasheet, JAN1N4101-1 pinout, JAN1N4101-1 application, or JAN1N4101-1 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (250 °C/W junction-to-lead), noise performance at 8.2 V, and MIL-qualified reliability level - all critical for precision reference and radiation-hardened systems.
Technical Context
The JAN1N4101-1 functions as a two-terminal reverse-biased voltage reference, operating in Zener breakdown mode with cathode band indicating polarity. Its metallurgical bond ensures mechanical robustness and long-term stability under thermal cycling and shock.
It exhibits a positive temperature coefficient of +0.070 %/°C and maintains ≤0.5 µA reverse leakage at 6.56 V, enabling use in low-drift analog references and power supply feedback paths where predictable TC and low IR are essential.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US | Same 8.2 V nominal Zener, but in surface-mount DO-213AA package; no MIL qualification | Lacks JAN-level screening and radiation hardness; suitable only for commercial industrial PCBs | Select when board space is constrained and military reliability not required |
| JANTXV1N4101-1 | Identical electrical specs and DO-35 package, but qualified to JANTXV level per MIL-PRF-19500/435 | Higher screening (including burn-in and life test) and tighter lot traceability than JAN grade | Select when extended reliability, longer qualification life, or mission-critical redundancy is mandated |
Compared with JAN1N4101-1, 1N4101US trades MIL qualification and radiation tolerance for SMT compatibility, while JANTXV1N4101-1 provides enhanced screening and process controls without changing electrical behavior - enabling direct substitution where higher reliability assurance is needed.

FAQ
What is the Zener voltage tolerance for JAN1N4101-1?
JAN1N4101-1 has a nominal Zener voltage of 8.2 V with a ±5% tolerance, as defined in the JEDEC-registered specification and verified per MIL-PRF-19500/435 screening. This tolerance applies at 250 mA test current and 25 °C ambient, and is maintained across the full JAN qualification lot acceptance testing.
Is JAN1N4101-1 RoHS compliant?
No, JAN1N4101-1 is not RoHS compliant. The JAN reliability level uses traditional tin-lead plating per MIL-STD-750, method 2026. RoHS-compliant versions (e3 suffix) are available only on commercial-grade variants such as 1N4101-1e3, not on JAN-qualified parts.
What is the maximum Zener current IZM for JAN1N4101-1?
The maximum Zener current IZM for JAN1N4101-1 is 6.3 mA, calculated from its 500 mW power rating and 8.2 V nominal Zener voltage (IZM = 0.5 W / 8.2 V ≈ 61 mA), but limited by thermal constraints to 6.3 mA at 25 °C lead temperature per the manufacturer's derating curve and absolute maximum ratings table.
Does JAN1N4101-1 have radiation hardness certification?
Yes, JAN1N4101-1 is inherently radiation hard per Microsemi MicroNote 050. While not individually tested per MIL-STD-883, its metallurgically bonded DO-35 construction and silicon process yield demonstrated TID tolerance suitable for low-earth orbit and terrestrial nuclear environments - a documented characteristic of the entire 1N4099–1N4135-1 series.
What is the thermal resistance junction-to-lead (RθJL) for JAN1N4101-1?
JAN1N4101-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured with 10 mm (3/8 inch) lead length from the package body, per MIL-PRF-19500/435 test conditions. This value enables accurate thermal modeling for high-temperature mounting configurations in sealed enclosures or thermally conductive fixtures.
