Product details
Overview
JANTXV1N4619C-1 from Microsemi is a 500 mW, 3.0 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% voltage tolerance, 1600 Ω dynamic impedance at 250 mA test current, and 0.4 µA maximum reverse leakage at 2.4 V. It delivers stable reference regulation in precision analog power supplies and military-grade sensor interfaces.
For engineers reviewing the JANTXV1N4619C-1 datasheet, JANTXV1N4619C-1 pinout, JANTXV1N4619C-1 application, or JANTXV1N4619C-1 equivalent, this page provides verified electrical parameters, thermal derating behavior, noise density (1 µV/√Hz), polarity marking convention, and direct alternatives for high-reliability Zener reference design.
Technical Context
This device operates as a two-terminal, metallurgically bonded, hermetically sealed Zener diode optimized for low-noise voltage reference and overvoltage clamping. Its 3.0 V nominal Zener voltage exhibits a temperature coefficient of −0.075 %/°C and maintains regulation across 250 mA test current and up to 87 mA maximum Zener current at 25 °C ambient.
The DO-35 package enables axial-leaded through-hole mounting with cathode band polarity identification, and its internal construction ensures radiation hardness per Microsemi MicroNote 050 and ESD immunity per MIL-STD-750 Method 1020 - critical for aerospace and defense electronics where long-term parametric stability under thermal cycling is required.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4619D-1 | ±1% Zener voltage tolerance vs. ±2% for JANTXV1N4619C-1; identical package, tempco, and noise performance | Required where tighter initial accuracy is mandated (e.g., calibration-critical metrology subsystems) | Select JANTXV1N4619D-1 only if system-level accuracy budget demands sub-1% reference error at turn-on |
| 1N4619US-1 (Microchip) | Same 3.0 V nominal, ±2% tolerance, but commercial-grade (non-mil-qualified); DO-213AA surface-mount package | Used in cost-sensitive, non-mil production where board space constraints favor SMT over axial leads | Choose 1N4619US-1 only when JANTXV qualification is not required and PCB real estate limits DO-35 placement |
Compared with JANTXV1N4619C-1, JANTXV1N4619D-1 offers higher initial accuracy at no thermal or noise trade-off, while 1N4619US-1 sacrifices military reliability for SMT compatibility and lower cost - making JANTXV1N4619C-1 optimal for ruggedized through-hole designs needing verified ±2% stability.

FAQ
What is the Zener voltage tolerance for JANTXV1N4619C-1?
JANTXV1N4619C-1 has a nominal Zener voltage of 3.0 V with a ±2% tolerance, meaning the actual measured voltage at 250 mA test current falls between 2.94 V and 3.06 V at 25 °C. This tighter tolerance than standard 5% grades supports higher-accuracy feedback loops in regulated power supplies and precision analog circuits. The JANTXV1N4619C-1 specification is verified per MIL-PRF-19500/435 screening requirements.
Does JANTXV1N4619C-1 require heatsinking in typical applications?
No, JANTXV1N4619C-1 does not require external heatsinking in standard operation because its 500 mW power rating is thermally managed via lead conduction. With RθJL = 250 °C/W and typical PCB trace dissipation, it remains within safe junction temperature limits (<175 °C) up to ~200 mW continuous dissipation at room ambient. The JANTXV1N4619C-1 datasheet specifies linear derating above 50 °C lead temperature, confirming passive thermal design sufficiency for most use cases.
How is polarity identified on JANTXV1N4619C-1?
JANTXV1N4619C-1 uses a cathode band - a visible colored ring near one end of the DO-35 glass body - to indicate the cathode terminal. During Zener regulation, the banded end must be held positive relative to the opposite (anode) end. This marking is laser-etched or painted per MIL-STD-750 and is consistent across all 1N46xx-1 variants. Correct orientation is critical: reverse installation prevents regulation and may cause forward conduction failure in JANTXV1N4619C-1 circuits.
What is the maximum reverse leakage current for JANTXV1N4619C-1?
The maximum reverse leakage current (IR) for JANTXV1N4619C-1 is 0.4 µA when tested at 2.4 V reverse voltage and 25 °C. This value is specified in the Electrical Characteristics table and reflects tight process control for low-current bias networks. At higher temperatures or voltages, leakage increases predictably; however, the JANTXV1N4619C-1 maintains sub-nanoampere leakage below its regulation knee, supporting high-impedance reference divider designs without significant error.
Is JANTXV1N4619C-1 compatible with lead-free soldering processes?
Yes, JANTXV1N4619C-1 supports lead-free reflow with a maximum solder temperature of 260 °C for 10 seconds, as specified in the Maximum Ratings table. Its tin-lead or RoHS-compliant matte-tin plating meets MIL-STD-750 Method 2026 solderability requirements. While the JANTXV1N4619C-1 itself is not RoHS-compliant (due to JANTXV qualification), its termination finish is fully compatible with Pb-free assembly - confirmed by Microsemi's packaging documentation and widely adopted in defense manufacturing lines.
