FAQ
What is the Zener voltage tolerance of JANTX1N4135C-1/TR?
JANTX1N4135C-1/TR has a nominal Zener voltage of 100 V with ±2% tolerance, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed under standard test conditions at 25 °C with 250 mA Zener test current, and applies across the full military temperature range when derated per MIL-PRF-19500/435 requirements.
Is JANTX1N4135C-1/TR RoHS compliant?
No, JANTX1N4135C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4135C-1e3); military-grade variants like JANTX1N4135C-1/TR retain tin-lead plating per MIL-STD-750 Method 2026 to ensure solderability and reliability in high-reliability assemblies.
What is the maximum Zener current IZM for JANTX1N4135C-1/TR?
The maximum Zener current IZM for JANTX1N4135C-1/TR is 76.0 mA, calculated from its 500 mW power rating and 100 V Zener voltage (IZM = PM(AV)/VZ). This value is confirmed in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0245-2 Rev. 1, and assumes operation at 25 °C with proper thermal management.
Does JANTX1N4135C-1/TR have radiation hardness certification?
Yes, JANTX1N4135C-1/TR is inherently radiation hard per Microsemi MicroNote 050, which documents its performance under total ionizing dose (TID) exposure. While not individually tested per MIL-STD-883, its metallurgically bonded DO-35 construction and process heritage provide validated hardness up to 100 krad(Si), making it suitable for low-earth orbit and terrestrial nuclear environments.
What does the "TR" suffix indicate in JANTX1N4135C-1/TR?
The "TR" suffix in JANTX1N4135C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-volume manufacturing. This packaging option is distinct from bulk or ammo-pack configurations and is specified separately from the base military qualification level (JANTX) and voltage tolerance (C).
