Overview
JANTX1N4619C-1 from Microsemi is a 500 mW, 3.0 V Zener diode in DO-35 glass package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% voltage tolerance, 1600 Ω dynamic impedance at 250 mA test current, and 0.4 µA max reverse leakage at 2.4 V. It serves as a precision voltage reference in military-grade power regulation circuits.
For engineers reviewing the JANTX1N4619C-1 datasheet, JANTX1N4619C-1 pinout, JANTX1N4619C-1 application, or JANTX1N4619C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), junction temperature range (–65°C to +175°C), thermal resistance (250°C/W junction-to-lead), noise density (1 µV/√Hz), and MIL-qualified reliability level.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable 3.0 V regulation across wide current (250 mA IZT) and temperature (–65°C to +175°C) ranges. Its metallurgically bonded construction ensures low noise (1 µV/√Hz) and radiation hardness per MicroNote 050.
The JANTX1N4619C-1 exhibits a negative temperature coefficient of –0.075 %/°C and is rated for 0.5 W average power dissipation with linear derating above 50°C lead temperature. It features hermetically sealed DO-35 packaging with cathode band marking and tin-lead plating compliant with MIL-STD-750 method 2026.

FAQ
What is the Zener voltage tolerance of JANTX1N4619C-1?
JANTX1N4619C-1 has a nominal Zener voltage of 3.0 V with a ±2% tolerance, 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 applies across the full qualified temperature range of –65°C to +175°C.
Is JANTX1N4619C-1 RoHS compliant?
No, JANTX1N4619C-1 is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4619C-1e3); the JANTX prefix indicates military qualification with tin-lead plating per MIL-STD-750, which falls outside RoHS exemptions for high-reliability applications.
What is the maximum reverse leakage current for JANTX1N4619C-1?
The maximum reverse leakage current (IR) for JANTX1N4619C-1 is 0.4 µA at VR = 2.4 V, as specified in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet. This value is measured at 25°C and reflects tight control over low-current regulation performance.
Can JANTX1N4619C-1 be used in surface-mount designs?
No, JANTX1N4619C-1 uses the axial-leaded DO-35 (DO-204AH) package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4619US-1 in DO-213AA or 1PMT4619 in DO-216 - both share identical electrical specs but differ in mechanical form factor and qualification level.
What does the "JANTX" prefix signify for JANTX1N4619C-1?
The "JANTX" prefix on JANTX1N4619C-1 indicates compliance with Level 2 reliability screening per MIL-PRF-19500/435, including extended temperature cycling, hermeticity testing, and lot acceptance tests beyond commercial standards - making it suitable for demanding military and aerospace applications.
