Product details
Overview
JAN1N4115C-1/TR from Microsemi is a 22 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4115C-1/TR datasheet, JAN1N4115C-1/TR pinout, JAN1N4115C-1/TR application, or JAN1N4115C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), noise density (1 µV/√Hz), dynamic impedance (150 Ω), temperature coefficient (+0.090 %/°C), and JANS-qualified reliability grading.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 22 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable regulation across -65 °C to +175 °C junction temperature range.
Its metallurgical bond construction ensures robust thermal performance (RθJL = 250 °C/W) and radiation hardness per MicroNote 050, while the DO-35 hermetically sealed glass package supports axial-leaded mounting in harsh-environment analog circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4115US-1 | Same 22 V/2% spec but in DO-213AA surface-mount package | Requires PCB rework for SMT assembly; no axial lead option | Select when automated placement and board space reduction are prioritized over through-hole serviceability |
| JANTXV1N4115C-1 | Identical electrical specs but qualified to JANTXV level with enhanced screening | Higher cost and longer lead time; required only for Class H/V systems with strict burn-in and lot traceability | Select when full JANTXV compliance is mandated by program specification, not just JAN |
Compared with JAN1N4115C-1/TR, 1N4115US-1 offers footprint reduction at the expense of manual repairability, while JANTXV1N4115C-1 adds screening rigor without altering regulation performance-making the JAN version optimal for cost-sensitive, high-reliability through-hole designs.

FAQ
What is the Zener voltage tolerance of JAN1N4115C-1/TR?
The JAN1N4115C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature per Microsemi's part numbering system. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, where JAN1N4115-1 (5% standard) is contrasted with JAN1N4115C-1 (2% tolerance). The device delivers 22 V regulation within this tighter band at 250 mA test current.
Is JAN1N4115C-1/TR RoHS compliant?
No, JAN1N4115C-1/TR is not RoHS compliant. Per the nomenclature guide on page 2 of T4-LDS-0245-2, RoHS compliance is indicated by the "e3" suffix (e.g., JAN1N4115C-1e3), which is absent in this part number. The JAN1N4115C-1/TR uses traditional tin-lead plating and is intended for legacy military applications where RoHS exemptions apply.
What does the "TR" suffix mean in JAN1N4115C-1/TR?
The "TR" suffix in JAN1N4115C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. As stated on page 2 of T4-LDS-0245-2, this option is available for all parts in the series, and the factory should be consulted for minimum order quantities. The electrical and mechanical specifications of JAN1N4115C-1/TR remain identical to the bulk version.
What is the maximum Zener current IZM for JAN1N4115C-1/TR?
The maximum Zener current IZM for JAN1N4115C-1/TR is 40 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value corresponds to the 22 V entry (JAN1N4115-1/C-1) and reflects the current limit that maintains safe 500 mW power dissipation at rated voltage, assuming thermal equilibrium at 25 °C.
How is polarity marked on JAN1N4115C-1/TR?
Polarity on JAN1N4115C-1/TR is marked by a visible cathode band on the glass DO-35 body. As stated in the Mechanical and Packaging section (page 2), the banded end is the cathode and must be held at a higher potential than the anode for proper Zener regulation. This marking is consistent across all devices in the 1N4099–1N4135 series and is verified visually during inspection.
