Product details
Overview
JANS1N4101-1/TR from Microsemi is a 500 mW, 8.2 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance, 0.5 µA reverse leakage at 6.3 V, and +0.070 %/°C temperature coefficient.
For engineers reviewing the JANS1N4101-1/TR datasheet, JANS1N4101-1/TR pinout, JANS1N4101-1/TR application, or JANS1N4101-1/TR equivalent, key selection criteria include military-grade reliability qualification, low-noise performance (1 µV/√Hz typical), thermal resistance of 250 °C/W junction-to-lead, and compatibility with lead-free soldering at 260 °C for 10 s.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock, while hermetic glass sealing provides immunity to moisture and contaminants per MIL-STD-750 method 1020.
The JANS1N4101-1/TR exhibits minimal capacitance (~5 pF typical at 8.2 V), enabling use in noise-sensitive analog references and low-jitter timing circuits. Its temperature coefficient (+0.070 %/°C) supports stable operation across –65 °C to +175 °C junction range without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4101-1 | Same electrical specs but qualified only to JANTXV level; lacks JANS radiation hardness validation | Suitable for non-space airborne platforms where total ionizing dose <10 krad(Si) is expected | Select when cost sensitivity outweighs need for Class S radiation assurance |
| 1N4101US-TR | Surface-mount DO-213AA package; identical VZ/IZT/ZZT but RθJA = 400 °C/W vs. 250 °C/W for JANS1N4101-1/TR | Preferred for high-density PCBs where axial leads are incompatible with automated assembly | Choose when board space constraints prohibit axial mounting and thermal derating allows 400 °C/W |
Compared with JANTXV1N4101-1 and 1N4101US-TR, the JANS1N4101-1/TR uniquely combines JANS-level radiation hardness, axial-lead mechanical robustness, and 250 °C/W junction-to-lead thermal resistance-making it the sole choice for space-qualified shunt references demanding zero parameter shift after 100 krad(Si) exposure.

FAQ
What is the Zener voltage tolerance for JANS1N4101-1/TR?
The JANS1N4101-1/TR has a nominal Zener voltage of 8.2 V with a ±5% tolerance, measured at 250 mA test current and 25 °C ambient. This tolerance is standard for the JAN/JANS-qualified 1N4099–1N4135 series and reflects the military-grade specification per MIL-PRF-19500/435.
Is JANS1N4101-1/TR compatible with lead-free soldering processes?
Yes, JANS1N4101-1/TR supports lead-free soldering at 260 °C for 10 seconds per MIL-STD-750 method 2026. Its tin-lead or RoHS-compliant matte-tin plating ensures reliable wetting and intermetallic formation without whisker risk or joint embrittlement.
What is the maximum reverse leakage current for JANS1N4101-1/TR?
The maximum reverse leakage current (IR) for JANS1N4101-1/TR is 0.5 µA at 6.3 V reverse voltage and 25 °C. This low leakage enables minimal quiescent current draw in battery-powered reference circuits and high-impedance sensing nodes.
Does JANS1N4101-1/TR require external heat sinking?
No, JANS1N4101-1/TR does not require external heat sinking under typical conditions. With a junction-to-lead thermal resistance of 250 °C/W and rated 500 mW dissipation at 25 °C, it operates within safe limits when mounted with ≥10 mm lead length from body per MIL-PRF-19500/435 test conditions.
How is polarity marked on JANS1N4101-1/TR?
Polarity on JANS1N4101-1/TR is indicated by a single black cathode band on the glass body. The banded end is the cathode and must be connected to the higher-potential node (positive side) for proper Zener regulation; the unbanded end is the anode and connects to circuit common.
