For engineers reviewing the JANTX1N4619C-1/TR datasheet, JANTX1N4619C-1/TR pinout, JANTX1N4619C-1/TR application, or JANTX1N4619C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, noise density, power derating behavior, and mil-spec qualification status - critical for high-reliability analog reference design, voltage clamping, and biasing in aerospace and defense systems.
Technical Context
This device operates as a reverse-biased Zener regulator with nominal 3.0 V breakdown at 250 mA (IZT), exhibiting a negative temperature coefficient of –0.075 %/°C and dynamic impedance of 1600 Ω under specified test conditions. Its metallurgically bonded construction ensures stable regulation across –65 °C to +175 °C junction temperature range.
Designed for low-noise analog references, it delivers 1 μV/√Hz noise density at IZT and maintains ≤0.4 μA reverse leakage (IR) at VR = 2.0 V. The DO-35 package supports axial mounting with cathode band polarity marking and tin-lead plating compliant with MIL-STD-750 method 2026.

FAQ
What is the Zener voltage tolerance for JANTX1N4619C-1/TR?
JANTX1N4619C-1/TR has a nominal Zener voltage of 3.0 V with a ±2% tolerance, meaning the actual measured VZ falls between 2.94 V and 3.06 V at 250 mA test current and 25 °C ambient. This tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1 and applies specifically to the "C" suffix variant of JANTX1N4619C-1/TR.
Is JANTX1N4619C-1/TR qualified to MIL-PRF-19500/435?
Yes, JANTX1N4619C-1/TR is qualified to MIL-PRF-19500/435 at the JANTX reliability level, as stated in the DESCRIPTION section on page 1 of T4-LDS-0245-2 Rev. 1. This qualification covers screening, testing, and process controls required for high-reliability military applications, including temperature cycling, burn-in, and parametric verification.
What is the maximum reverse leakage current for JANTX1N4619C-1/TR?
The maximum reverse leakage current (IR) for JANTX1N4619C-1/TR is 0.4 μA at VR = 2.0 V, per the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value reflects worst-case leakage under specified test conditions and is critical for low-power bias network design where standby current must remain sub-microamp.
Does JANTX1N4619C-1/TR have a positive or negative temperature coefficient?
JANTX1N4619C-1/TR has a negative temperature coefficient of –0.075 %/°C, as documented in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This means its Zener voltage decreases by approximately 2.25 mV per °C rise in junction temperature - a key factor in thermal drift compensation for precision analog circuits using JANTX1N4619C-1/TR.
What package type is used for JANTX1N4619C-1/TR?
JANTX1N4619C-1/TR uses the DO-35 (DO-204AH) hermetically sealed axial-leaded glass package, as specified in the MECHANICAL and PACKAGING section on page 2 of T4-LDS-0245-2 Rev. 1. The package features tin-lead plating, cathode band marking, and mechanical dimensions compliant with JEDEC standards for through-hole mounting and manual or wave soldering.
