Overview
JANS1N4115C-1/TR from Microsemi is a 22 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications, with dynamic impedance of 150 Ω at 250 mA and temperature coefficient of +0.090 %/°C.
For engineers reviewing the JANS1N4115C-1/TR datasheet, JANS1N4115C-1/TR pinout, JANS1N4115C-1/TR application, or JANS1N4115C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), radiation hardness, noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and JANS-level qualification for extended temperature operation (-65 to +175 °C).
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, with cathode band marking polarity and specified regulation at IZT = 250 mA. Its metallurgical bond construction ensures stable long-term Zener voltage under thermal cycling and radiation exposure.
The JANS1N4115C-1/TR exhibits low noise density (1 µV/√Hz), minimal capacitance (typical <2 pF at 22 V), and a positive temperature coefficient (+0.090 %/°C) enabling predictable drift compensation in analog reference circuits across military temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4115US-1/TR | Same 22 V, 2% Zener voltage but in surface-mount DO-213AA package; no JANS qualification | Limited to commercial/industrial PCBs requiring reflow assembly; not suitable for hermetic module integration | Select when automated SMT placement is required and radiation/military qualification is unnecessary |
| JANTXV1N4115C-1/TR | Identical electrical specs but qualified only to JANTXV level; lower screening rigor than JANS | Approved for high-reliability ground-based systems but excluded from flight-critical avionics per DoD requirements | Select when full JANS qualification is not mandated but extended temperature and burn-in testing are needed |
Compared with JANS1N4115C-1/TR, the JANTXV variant offers reduced cost and lead time for non-flight hardware, while the 1N4115US-1/TR enables miniaturized layouts at the expense of environmental ruggedness and radiation tolerance.

FAQ
What is the Zener voltage tolerance of JANS1N4115C-1/TR?
JANS1N4115C-1/TR has a nominal Zener voltage of 22.0 V with a tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and remains stable across the full -65 to +175 °C operating range due to JANS-level screening.
Is JANS1N4115C-1/TR radiation hardened?
Yes, JANS1N4115C-1/TR is inherently radiation hard per Microsemi MicroNote 050, with demonstrated resilience to total ionizing dose (TID) effects. Its metallurgically bonded structure and hermetic DO-35 packaging contribute to this hardness, making it suitable for satellite payload and nuclear instrumentation applications where radiation exposure is expected.
What does the "TR" suffix mean in JANS1N4115C-1/TR?
The "TR" suffix in JANS1N4115C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and supports consistent handling and traceability; the underlying device remains identical to the bulk version in electrical and reliability specifications.
How is polarity marked on JANS1N4115C-1/TR?
JANS1N4115C-1/TR uses a cathode band marking on the glass body to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking complies with JEDEC standards and is visible under standard visual inspection during manual or automated assembly.
What is the maximum Zener current IZM for JANS1N4115C-1/TR?
The maximum Zener current IZM for JANS1N4115C-1/TR is 16.8 mA at 22 V, calculated from its 500 mW power rating (IZM = PM(AV)/VZ). Derating begins linearly at 50 °C lead temperature and reaches zero at 175 °C, ensuring safe operation under sustained thermal stress in enclosed military enclosures.
