Product details
Overview
JANTX1N4619D-1/TR from Microsemi is a 1% tolerance, 3.0 V Zener voltage regulator diode in DO-35 glass package, rated for 500 mW power dissipation, with 1600 Ω dynamic impedance at 250 mA test current and 0.4 µA maximum reverse leakage at 2.4 V, used for precision voltage reference and regulation in military-grade analog circuits.
For engineers reviewing the JANTX1N4619D-1/TR datasheet, JANTX1N4619D-1/TR pinout, JANTX1N4619D-1/TR application, or JANTX1N4619D-1/TR equivalent, this page delivers verified MIL-PRF-19500/435 qualified parameters, DO-35 terminal polarity, axial-leaded mounting context, and direct replacement options for high-reliability voltage reference design.
Technical Context
This device operates as a reverse-biased Zener diode with metallurgically bonded junction, delivering stable 3.0 V regulation across 250 mA test current and temperature range −65 °C to +175 °C. Its 1% voltage tolerance (D suffix), low noise density (1 µV/√Hz), and −0.075 %/°C temperature coefficient enable precision analog referencing.
Designed for high-reliability environments, JANTX1N4619D-1/TR meets JAN-level qualification per MIL-PRF-19500/435, features hermetically sealed glass DO-35 packaging, and exhibits minimal capacitance (<2 pF typical) and non-ESD-sensitive behavior per MIL-STD-750 Method 1020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4619D-1/TR | Higher qualification level (JANTXV vs JANTX); tighter screening, extended temperature validation, lower failure rate | Required for space-grade or Class H avionics where burn-in and radiation testing are mandated | Select when program spec requires JANTXV-level reliability; same electrical specs and DO-35 footprint |
| 1N4619US-1 | Surface-mount DO-213AA package; identical electrical specs but no axial leads | Suitable for automated SMT assembly; not compatible with through-hole PCBs or manual prototyping | Choose for volume production with reflow capability; verify thermal pad layout matches RθJL = 250 °C/W requirement |

FAQ
What is the Zener voltage and tolerance of JANTX1N4619D-1/TR?
JANTX1N4619D-1/TR has a nominal Zener voltage of 3.0 V with ±1% tolerance, measured at 250 mA test current and 25 °C. The "D" suffix explicitly denotes the 1% tolerance grade, confirmed in Microsemi's T4-LDS-0245-2 datasheet, Table on Page 3. This tight tolerance supports high-accuracy reference design without post-manufacture trimming.
Is JANTX1N4619D-1/TR RoHS compliant?
JANTX1N4619D-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTX1N4619D-1/TR. Its lead finish is tin-lead per MIL-STD-750, required for military reliability standards.
What package type does JANTX1N4619D-1/TR use?
JANTX1N4619D-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Dimensions and mechanical specifications are documented on Page 5 of the T4-LDS-0245-2 datasheet, confirming body diameter 1.42–2.29 mm and lead length 25.4–38.1 mm.
What is the maximum power dissipation for JANTX1N4619D-1/TR?
JANTX1N4619D-1/TR has a rated average power dissipation of 0.5 W (500 mW) at 25 °C case temperature. Derating is linear: power drops to zero at 175 °C, beginning at 50 °C per Note 2 on Page 1 of the datasheet. Thermal resistance junction-to-lead is 250 °C/W with 10 mm lead length.
How is polarity marked on JANTX1N4619D-1/TR?
JANTX1N4619D-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the unmarked (anode) end for proper Zener regulation. This marking convention is specified in the "MECHANICAL and PACKAGING" section on Page 2 of the T4-LDS-0245-2 datasheet.
