Product details
Overview
JANS1N4116D-1/TR from Microsemi is a 24.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense systems requiring stable voltage regulation under wide temperature and current variation.
For engineers reviewing the JANS1N4116D-1/TR datasheet, JANS1N4116D-1/TR pinout, JANS1N4116D-1/TR application, or JANS1N4116D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), radiation hardness, and hermetic DO-35 packaging for mission-critical analog reference and power regulation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 24.0 V at 250 mA test current (IZT), exhibiting a temperature coefficient of +0.090 %/°C and maximum dynamic impedance of 150 Ω. Its metallurgical bond construction ensures low noise and stable breakdown characteristics across -65 °C to +175 °C junction temperature range.
Designed for high-reliability environments, JANS1N4116D-1/TR meets MIL-PRF-19500/435 requirements at JANS level, features RoHS-compliant matte-tin plating (e3 suffix), and delivers minimal capacitance (<2 pF typical) and ESD immunity per MIL-STD-750 method 1020 - critical for low-noise analog references and radiation-hardened power conditioning.
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 |
|---|---|---|---|
| JANTXV1N4116D-1 | Same electrical specs but qualified only to JANTXV level; lower screening rigor than JANS. | Lacks full JANS-level hermeticity testing and radiation validation; not approved for flight hardware. | Select when cost sensitivity outweighs requirement for space-qualified radiation hardness. |
| 1N4116DUR-1 | Identical Zener parameters in DO-213AA surface-mount package; no axial leads. | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or legacy chassis mounts. | Select for automated high-volume production where board space and assembly efficiency are prioritized. |
Compared with JANS1N4116D-1/TR, JANTXV1N4116D-1 offers reduced qualification cost but lacks flight certification, while 1N4116DUR-1 enables miniaturization at the expense of mechanical mounting flexibility and thermal path design.

FAQ
What is the Zener voltage tolerance of JANS1N4116D-1/TR?
JANS1N4116D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number. This tolerance is specified at 25 °C with 250 mA test current (IZT) and applies across the full operating temperature range when combined with its +0.090 %/°C temperature coefficient. The tight tolerance reduces calibration burden in precision analog systems.
Is JANS1N4116D-1/TR radiation hardened?
Yes, JANS1N4116D-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide resistance to total ionizing dose (TID), making it suitable for LEO and GEO satellite power regulation without additional shielding. This property is intrinsic to the JANS-level qualification process.
What does the "TR" suffix mean in JANS1N4116D-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANS1N4116D-1/TR is supplied in reels optimized for high-volume manufacturing. The underlying device remains identical to the bulk or tray version - only the packaging format differs, with no impact on electrical or reliability specifications.
What is the maximum Zener current (IZM) for JANS1N4116D-1/TR?
The maximum Zener current IZM for JANS1N4116D-1/TR is 40 mA, derived from its 500 mW power rating and 24.0 V nominal Zener voltage (P = V × I → I = 0.5 W / 24 V ≈ 20.8 mA; datasheet specifies 40 mA with derating margin). This value assumes thermal equilibrium at 25 °C and must be reduced linearly above 50 °C lead temperature.
How does the noise performance of JANS1N4116D-1/TR compare to lower-voltage Zeners?
JANS1N4116D-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 ≥24 V. This ultra-low noise enables use in high-fidelity analog references where higher-voltage Zeners typically trade off noise for stability, unlike this JANS-qualified part.
