Product details
Overview
JANS1N4105D-1/TR from Microsemi is a 11.0 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 aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance and +0.080 %/°C temperature coefficient.
For engineers reviewing the JANS1N4105D-1/TR datasheet, JANS1N4105D-1/TR pinout, JANS1N4105D-1/TR application, or JANS1N4105D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), radiation hardness, hermetic glass packaging, MIL-qualified reliability level, and low noise density (1 µV/√Hz).
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 mechanical robustness and thermal stability across -65 °C to +175 °C junction temperature range.
It exhibits low dynamic impedance (200 Ω at 250 mA), minimal capacitance (typical 40 pF), and inherent radiation hardness per Microsemi MicroNote 050 - characteristics critical for analog reference, power supply feedback, and voltage clamping in harsh environments.

FAQ
What is the Zener voltage and tolerance of JANS1N4105D-1/TR?
JANS1N4105D-1/TR has a nominal Zener voltage of 11.0 V with ±1% tolerance at 250 mA test current. This tight tolerance is achieved through post-package screening and is guaranteed under MIL-PRF-19500/435 JANS qualification, ensuring consistent performance in precision reference applications.
Is JANS1N4105D-1/TR radiation hardened?
Yes, JANS1N4105D-1/TR is inherently radiation hard per Microsemi MicroNote 050 due to its metallurgically bonded silicon die and hermetic DO-35 glass package. It requires no additional shielding and maintains parametric stability after exposure to total ionizing dose (TID) levels typical of low-earth orbit missions.
What does the "D" in JANS1N4105D-1/TR signify?
The "D" in JANS1N4105D-1/TR indicates 1% Zener voltage tolerance per the Microsemi part nomenclature. The "TR" suffix denotes tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-reliability assembly lines.
Can JANS1N4105D-1/TR replace commercial 1N4105 diodes in existing designs?
JANS1N4105D-1/TR shares identical electrical specifications with commercial 1N4105 variants but adds JANS-level screening, hermetic packaging, and radiation hardness. It can replace commercial versions in new designs targeting high-reliability environments, though qualification testing per application requirements is recommended.
What is the maximum operating temperature for JANS1N4105D-1/TR?
JANS1N4105D-1/TR has a junction and storage temperature range of -65 °C to +175 °C. Its power dissipation linearly derates from 500 mW at 25 °C to zero at 175 °C, supporting continuous operation in extreme thermal environments such as engine-mounted avionics or reactor containment zones.
