It delivers stable reference voltage with 200 Ω dynamic impedance at 250 mA test current, 0.5 µA max reverse leakage at 7.6 V, and +0.080 %/°C temperature coefficient.
For engineers reviewing the JANS1N4104D-1/TR datasheet, JANS1N4104D-1/TR pinout, JANS1N4104D-1/TR application, or JANS1N4104D-1/TR equivalent, key selection criteria include its JANS-level radiation-hardened qualification, 1% Zener voltage tolerance, low noise density (≤1 µV/√Hz below 6.8 V), and hermetic DO-35 packaging for extreme-environment analog reference stability.
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 long-term parameter stability under thermal cycling and radiation exposure.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4104US-1/TR | Same electrical specs but in surface-mount DO-213AA package; no JANS qualification | Lacks radiation hardness and extended temperature validation; suitable only for commercial PCB assembly | Select when board space constraints require SMT and MIL-spec reliability is not required |
| JANTXV1N4104D-1/TR | Identical Zener parameters and DO-35 package; qualified to JANTXV level (not JANS) | Lower radiation tolerance and reduced screening depth vs. JANS; approved for non-space defense programs | Select when full JANS qualification is unnecessary but enhanced reliability beyond commercial grade is needed |
Compared with JANS1N4104D-1/TR, the JANTXV variant offers cost savings and faster lead times while retaining most environmental robustness, whereas the 1N4104US-1/TR trades qualification for SMT compatibility-neither is pin-compatible due to differing packages or screening levels.

Is JANS1N4104D-1/TR radiation hardened?
Yes, JANS1N4104D-1/TR is inherently radiation hard per Microsemi MicroNote 050 due to its metallurgically bonded structure and hermetic DO-35 packaging. It is qualified to JANS level under MIL-PRF-19500/435, which includes radiation testing protocols appropriate for spaceflight applications.
What is the maximum reverse leakage current for JANS1N4104D-1/TR?
The maximum reverse leakage current (IR) for JANS1N4104D-1/TR is 0.5 µA at VR = 7.6 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This value is guaranteed across the full operating temperature range and after JANS-level environmental stress screening.
Does JANS1N4104D-1/TR have a specified noise density?
Yes, JANS1N4104D-1/TR has a noise density of ≤1 µV/√Hz, consistent with devices rated below 6.8 V in the 1N4099–1N4135 series. This low noise performance is confirmed in the FEATURES section and supported by Figure 1 (Noise Density Measurement Circuit) in the datasheet.
What package type is used for JANS1N4104D-1/TR?
JANS1N4104D-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Dimensions are fully specified on page 5 of T4-LDS-0245-2, with body diameter 1.42–2.29 mm and overall length 25.4–38.1 mm.
