Product details
Overview
JANTXV1N4623C-1 from Microsemi is a 500 mW, 4.3 V Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTXV level per MIL-PRF-19500/435, with 2% voltage tolerance, 1600 Ω dynamic impedance at 250 mA test current, and -0.050 %/°C temperature coefficient - used for precision voltage reference and regulation in military-grade power supply feedback paths.
For engineers reviewing the JANTXV1N4623C-1 datasheet, JANTXV1N4623C-1 pinout, JANTXV1N4623C-1 application, or JANTXV1N4623C-1 equivalent, key selection criteria include Zener voltage accuracy, low noise density (1 µV/√Hz), hermetic glass packaging, MIL-spec qualification level, and thermal resistance (250 °C/W junction-to-lead).
Technical Context
This device operates as a reverse-biased voltage regulator with metallurgically bonded construction for enhanced reliability. Its Zener voltage of 4.3 V is specified at 250 mA test current (IZT), with dynamic impedance of 1600 Ω measured at 10% AC modulation superimposed on IZT.
It exhibits a negative temperature coefficient of -0.050 %/°C, enabling stable regulation across -65 °C to +175 °C operating range. Noise density is 1 µV/√Hz - among the lowest in the 1N46xx series - due to optimized low-voltage Zener structure and internal bond integrity.
Key Specifications

FAQ
What is the Zener voltage tolerance of JANTXV1N4623C-1?
JANTXV1N4623C-1 has a Zener voltage tolerance of ±2%, corresponding to a 4.3 V nominal rating ranging from 4.214 V to 4.386 V at 250 mA test current and 25 °C. This tolerance is defined by the "C" suffix in the part number per Microsemi's nomenclature and is verified per MIL-PRF-19500/435 screening.
Is JANTXV1N4623C-1 suitable for surface-mount assembly?
No - JANTXV1N4623C-1 uses an axial-leaded DO-35 (DO-204AH) glass package and is not compatible with reflow or wave soldering for SMT processes. For surface-mount equivalents, consider the 1N4623UR-1 in DO-213AA or 1PMT4623 in DO-216, both commercial-grade variants without MIL qualification.
What is the maximum Zener current (IZM) for JANTXV1N4623C-1?
The maximum Zener current IZM for JANTXV1N4623C-1 is 77 mA, calculated from its 500 mW power rating and 4.3 V Zener voltage (IZM = PM(AV)/VZ). Derating begins linearly at 50 °C case temperature, reaching zero at 175 °C per Figure 2 in the T4-LDS-0245-2 datasheet.
Does JANTXV1N4623C-1 require heatsinking in typical applications?
JANTXV1N4623C-1 does not require external heatsinking below ~150 mW dissipation. With RθJL = 250 °C/W, self-heating remains under 40 °C rise at 160 mW - well within its -65 °C to +175 °C junction range. Heatsinking becomes necessary only in sustained >300 mW operation or high ambient temperatures (>85 °C).
How is polarity marked on JANTXV1N4623C-1?
JANTXV1N4623C-1 uses a single black band to indicate the cathode terminal. During Zener regulation, the banded end must be held positive relative to the anode. This marking complies with JEDEC standards and is visible on the glass body near one lead; the unmarked lead is the anode.
