For engineers reviewing the JAN1N4105D-1/TR datasheet, JAN1N4105D-1/TR pinout, JAN1N4105D-1/TR application, or JAN1N4105D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification details essential for precision analog reference and overvoltage protection design.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 11.0 V at 250 mA test current, exhibiting +0.080 %/°C temperature coefficient and 200 Ω dynamic impedance (ZZT) at IZT. Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
Designed for high-reliability environments, JAN1N4105D-1/TR maintains ≤0.05 µA reverse leakage at 7.6 V (VR), delivers 40 µV/√Hz noise density at 11.0 V, and supports linear derating from 500 mW at 25 °C to zero at 175 °C ambient on standard FR4 PCB layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US-1 | Same 11.0 V, 1% spec but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process and PCB redesign; unsuitable for through-hole prototyping or legacy board repair | Select when automated assembly and board space reduction are priorities over manual serviceability |
| JANTXV1N4105D-1 | Identical electrical specs and DO-35 package, but qualified to JANTXV level (not JANS); lower screening rigor | Approved for high-reliability commercial aerospace but not spaceflight or nuclear command systems | Select when full JANS radiation hardness and extended life testing are not required |
Compared with JAN1N4105D-1/TR, 1N4105US-1 offers footprint miniaturization at the cost of assembly flexibility, while JANTXV1N4105D-1 reduces procurement cost and lead time without sacrificing core regulation performance in less demanding mil-aero roles.

Is JAN1N4105D-1/TR qualified to JANS level per MIL-PRF-19500/435?
Yes, JAN1N4105D-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, as stated in the official Microsemi documentation. The "JAN" prefix denotes military-grade reliability screening, and the "D" suffix confirms 1% voltage tolerance. This qualification includes radiation hardness, extended temperature operation, and lot traceability - all verified for JAN1N4105D-1/TR.
What is the maximum power dissipation and derating behavior of JAN1N4105D-1/TR?
JAN1N4105D-1/TR has a rated average power dissipation of 500 mW at 25 °C, linearly derated to zero at 175 °C ambient on a typical FR4 PCB. Derating begins at 50 °C lead temperature, with thermal resistance junction-to-ambient at 300 °C/W. These values are measured per Microsemi's T4-LDS-0245-2 specification sheet and apply directly to JAN1N4105D-1/TR.
Does JAN1N4105D-1/TR have low noise performance suitable for precision analog circuits?
Yes, JAN1N4105D-1/TR delivers 40 µV/√Hz noise density at its 11.0 V Zener voltage and 250 mA test current, as specified in the Electrical Characteristics table of T4-LDS-0245-2. This low noise performance is confirmed for frequencies between 1 kHz and 3 kHz and makes JAN1N4105D-1/TR appropriate for ADC reference buffers and low-noise sensor biasing.
What package type and marking does JAN1N4105D-1/TR use?
JAN1N4105D-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by a band.
