Product details
Overview
JAN1N4115D-1/TR from Microsemi is a 22 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4115D-1/TR datasheet, JAN1N4115D-1/TR pinout, JAN1N4115D-1/TR application, or JAN1N4115D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and JANS-level radiation hardness.
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 dynamic impedance (150 Ω) and minimal capacitance (typical 17 pF). Its metallurgical bond construction ensures stable regulation across wide current (1–40 mA) and temperature (−65 to +175 °C) ranges.
Designed for high-reliability environments, JAN1N4115D-1/TR meets MIL-PRF-19500/435 requirements for JANS qualification, features hermetic glass sealing, non-ESD-sensitive operation per MIL-STD-750 Method 1020, and inherent radiation hardness validated per Microsemi MicroNote 050.
Key Specifications

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, 1% spec but in DO-213AA surface-mount package; no axial leads. | Required for automated SMT assembly; lacks axial mounting flexibility for prototyping or repair. | Select when board space constraints or reflow-only processes prohibit through-hole components. |
| JANTXV1N4115D-1 | Identical electrical specs but qualified to JANTXV level (not JANS); lower screening rigor and radiation assurance. | Suitable for ground-based military systems where full JANS radiation hardness is not mandated. | Choose for cost-sensitive defense electronics where MIL-PRF-19500/435 JANTXV suffices. |
Compared with JAN1N4115D-1/TR, 1N4115US-1 offers SMT compatibility at the expense of mechanical robustness and thermal path control, while JANTXV1N4115D-1 reduces procurement cost and lead time but sacrifices radiation hardness validation required for spaceflight.

FAQ
What is the Zener voltage tolerance of JAN1N4115D-1/TR?
JAN1N4115D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This tight tolerance ensures the device delivers 22 V within ±0.22 V at 250 mA test current and 25 °C, making it suitable for high-accuracy reference applications where post-calibration is impractical.
Is JAN1N4115D-1/TR qualified for space applications?
Yes, JAN1N4115D-1/TR is qualified to JANS level per MIL-PRF-19500/435, including radiation hardness validation per Microsemi MicroNote 050. Its hermetic DO-35 package and metallurgical bond construction meet the environmental and reliability requirements for low-earth orbit and deep-space missions.
What is the maximum operating temperature for JAN1N4115D-1/TR?
JAN1N4115D-1/TR supports a junction and storage temperature range of −65 to +175 °C. At ambient temperatures above 50 °C, its 500 mW power rating must be linearly derated to zero at +175 °C, enabling reliable operation in high-temperature industrial and downhole environments.
Does JAN1N4115D-1/TR require special handling for ESD?
No, JAN1N4115D-1/TR is non-sensitive to ESD per MIL-STD-750 Method 1020. Its glass DO-35 construction and internal metallurgical bond eliminate gate oxide risks, allowing standard handling without ESD protection during assembly or testing.
How does the noise performance of JAN1N4115D-1/TR compare to lower-voltage Zeners?
JAN1N4115D-1/TR exhibits 1 µV/√Hz noise density at 250 mA, consistent with Microsemi's specification that noise falls rapidly below 6.8 V and stabilizes at ~1 µV/√Hz for voltages ≥20 V. This makes it significantly quieter than mid-range Zeners (e.g., 5.1 V parts at 2 µV/√Hz) and ideal for precision analog signal chains.
