Product details
Overview
JANS1N4103D-1/TR from Microsemi is a 500 mW, 9.1 V Zener voltage regulator diode in DO-35 glass package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers ±1% Zener voltage tolerance at 250 mA test current, exhibits 200 Ω dynamic impedance, and maintains regulation across -65°C to +175°C junction temperature range.
For engineers reviewing the JANS1N4103D-1/TR datasheet, JANS1N4103D-1/TR pinout, JANS1N4103D-1/TR application, or JANS1N4103D-1/TR equivalent, this page provides verified electrical parameters, military qualification status, thermal derating behavior, noise density (1 µV/√Hz), and direct alternatives with documented voltage/tolerance/package alignment.
Technical Context
This device operates as a precision shunt voltage reference in feedback loops and overvoltage protection circuits. Its metallurgically bonded construction ensures stable Zener voltage under radiation exposure and thermal cycling, with temperature coefficient of +0.080 %/°C confirmed for the 9.1 V variant.
The DO-35 axial-leaded glass package enables hermetic sealing and low parasitic capacitance (<2 pF typical at 9.1 V), while its 250 mA Zener test current and 7.0 mA maximum reverse leakage at 7.3 V support stable regulation in low-noise analog power rails and sensor biasing networks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4103D-1 | Same 9.1 V ±1%, DO-35 package, but qualified only to JANTXV level (not JANS); lower screening severity | Lacks full Class S radiation testing and lot traceability required for spacecraft avionics | Select when MIL-PRF-19500/435 Class B or C qualification suffices and cost sensitivity outweighs mission-critical reliability |
| 1N4103D-1/TR | Commercial-grade version with same electrical specs and DO-35/TR packaging, RoHS-compliant (e3 suffix) | No military qualification; not screened for temperature cycling, burn-in, or radiation | Appropriate for industrial test equipment or non-safety-critical embedded systems where JANS-level assurance is unnecessary |
Compared with JANS1N4103D-1/TR, JANTXV1N4103D-1 offers reduced qualification rigor for less demanding programs, while 1N4103D-1/TR provides identical performance at commercial cost-neither is pin-compatible with surface-mount variants like 1N4103UR-1 due to differing DO-213AA footprint.

FAQ
What is the Zener voltage tolerance and test current for JANS1N4103D-1/TR?
JANS1N4103D-1/TR has a nominal Zener voltage of 9.1 V with ±1% tolerance, measured at a Zener test current (IZT) of 250 mA. This tight tolerance is achieved through post-process binning and is specified under thermal equilibrium at 25°C ambient, supporting precision reference designs without external trimming.
Is JANS1N4103D-1/TR qualified for space applications?
Yes, JANS1N4103D-1/TR is qualified to JANS level per MIL-PRF-19500/435, including full Class S screening per MIL-STD-883. It undergoes radiation hardness assurance (RHA), temperature cycling, and lot traceability protocols required for geostationary and low-earth-orbit satellite subsystems.
What is the maximum reverse leakage current for JANS1N4103D-1/TR?
JANS1N4103D-1/TR specifies a maximum reverse leakage current (IR) of 0.5 µA at 7.3 V (80% of VZ). This ultra-low leakage ensures minimal loading on high-impedance bias networks in precision analog circuits and sensor interfaces.
Does JANS1N4103D-1/TR have a specified noise density?
Yes, JANS1N4103D-1/TR has a noise density of 1 µV/√Hz at 250 mA test current, measured in the 1 kHz–3 kHz band. This value is confirmed in the Microsemi datasheet and makes JANS1N4103D-1/TR suitable for low-noise reference applications such as high-resolution data converters.
What package type and marking does JANS1N4103D-1/TR use?
JANS1N4103D-1/TR uses the DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by a visible band. The device is marked with "JANS1N4103D-1" and supplied in tape-and-reel format (TR suffix), compliant with EIA-296 standards for automated placement.
