Product details
Overview
JANTXV1N4619D-1 from Microsemi is a 500 mW, 3.0 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4619D-1 datasheet, JANTXV1N4619D-1 pinout, JANTXV1N4619D-1 application, or JANTXV1N4619D-1 equivalent, key selection criteria include its 3.0 V nominal Zener voltage at 250 mA test current, 1600 Ω maximum dynamic impedance, 0.4 µA maximum reverse leakage at 2.4 V, 1 µV/√Hz noise density, and -0.075 %/°C temperature coefficient - all critical for precision low-voltage reference and biasing circuits.
Technical Context
This device operates as a two-terminal shunt voltage regulator with cathode-banded polarity, requiring forward bias of the anode relative to the banded cathode for normal Zener conduction. Its metallurgical bond construction ensures stable junction characteristics under thermal cycling and radiation exposure.
It delivers regulated output across wide current ranges (IZK near knee to IZM = 87 mA), with linear power derating from 500 mW at 25 °C ambient to zero at 175 °C, and exhibits minimal capacitance (<1.5 pF typical at 3.0 V) per Figure 3 - enabling use in low-noise analog references and timing circuit bias networks.
Key Specifications

FAQ
What is the Zener voltage tolerance of JANTXV1N4619D-1?
JANTXV1N4619D-1 has a nominal Zener voltage of 3.0 V with a ±1% tolerance, verified per MIL-PRF-19500/435 screening. This tight tolerance is achieved via post-trim testing and is specified at 250 mA test current and 25 °C ambient. The 'D' suffix in the part number explicitly denotes the 1% tolerance grade, distinguishing it from commercial-grade variants.
Is JANTXV1N4619D-1 suitable for radiation-hardened applications?
Yes, JANTXV1N4619D-1 is inherently radiation hard as documented in Microsemi MicroNote 050 and qualified to JANTXV level per MIL-PRF-19500/435. Its metallurgically bonded construction and hermetic glass package provide proven resilience against total ionizing dose (TID) and displacement damage, making it suitable for satellite and nuclear instrumentation applications without additional shielding.
What is the maximum Zener current rating for JANTXV1N4619D-1?
The maximum Zener current (IZM) for JANTXV1N4619D-1 is 87 mA, calculated from its 500 mW power rating and 3.0 V nominal Zener voltage (P = V × I). This value is valid at 25 °C lead temperature; current must be reduced linearly above 50 °C per the derating curve in Figure 2 of the datasheet to maintain safe junction temperature.
Does JANTXV1N4619D-1 require special ESD handling?
No, JANTXV1N4619D-1 is non-sensitive to ESD per MIL-STD-750 Method 1020, eliminating the need for static-dissipative packaging, grounded workstations, or wrist straps during handling and assembly. This simplifies integration into high-mix military production lines where ESD controls may be impractical.
How does the noise performance of JANTXV1N4619D-1 compare to higher-voltage Zeners in the same family?
JANTXV1N4619D-1 achieves 1 µV/√Hz noise density at 3.0 V, consistent with the family's trend of decreasing noise at lower Zener voltages. In contrast, 6.8 V and above devices exhibit up to 40 µV/√Hz. This makes JANTXV1N4619D-1 particularly suited for low-noise analog references where sub-millivolt RMS noise is critical to system resolution.
