Product details
Overview
JANTXV1N4627D-1 from Microsemi is a 1% tolerance, 6.2 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4627D-1 datasheet, JANTXV1N4627D-1 pinout, JANTXV1N4627D-1 application, or JANTXV1N4627D-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification details essential for precision reference and regulation design under extended temperature and radiation environments.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with Zener test current IZT = 250 mA and nominal VZ = 6.2 V at 25 °C. Its internal metallurgical bond ensures stable junction behavior across -65 °C to +175 °C operating range.
Dynamic impedance ZZT is 1200 Ω at IZT, and noise density ND is 5 µV/√Hz - critical for low-noise analog references. Temperature coefficient αVZ is -0.010/+0.050 %/°C, enabling predictable drift compensation in regulated power rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4627US-1 | Same VZ and tolerance, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mounting | Select when board space is constrained and automated placement is available |
| JANTXV1N4627-1 | Identical electrical specs but 5% voltage tolerance instead of 1% | Acceptable where calibration or trimming is performed downstream; higher binning yield lowers cost | Select when absolute voltage accuracy is secondary to cost and availability |
Compared with JANTXV1N4627D-1, the JANTXV1N4627-1 offers lower precision at reduced cost, while the 1N4627US-1 provides identical regulation in a compact SMT form - neither is pin-compatible due to differing packages and lead configurations.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4627D-1?
JANTXV1N4627D-1 has a nominal Zener voltage of 6.2 V with a tight ±1% tolerance at IZT = 250 mA and 25 °C. This tolerance is achieved via post-process binning and is guaranteed under MIL-PRF-19500/435 JANTXV screening. The D suffix explicitly denotes the 1% grade, distinguishing it from standard 5% variants like JANTXV1N4627-1.
Is JANTXV1N4627D-1 suitable for high-temperature operation?
Yes, JANTXV1N4627D-1 is rated for junction temperatures from -65 °C to +175 °C and is fully qualified to MIL-PRF-19500/435 JANTXV level. Its metallurgically bonded construction and hermetic DO-35 glass package ensure stable VZ and low IR drift across this full range, making it appropriate for engine-mounted avionics and downhole oilfield electronics.
What is the noise performance of JANTXV1N4627D-1?
JANTXV1N4627D-1 exhibits a noise density of 5 µV/√Hz at IZT = 250 mA, measured in the 1–3 kHz band. This low noise is confirmed in Microsemi's T4-LDS-0245-2 datasheet and results from optimized junction geometry and metallurgical bonding - critical for precision analog references in radar and instrumentation systems.
Does JANTXV1N4627D-1 have radiation hardness?
Yes, JANTXV1N4627D-1 is inherently radiation-hardened against total ionizing dose (TID), as documented in Microsemi MicroNote 050. Its glass-encapsulated, metallurgically bonded structure resists parametric degradation up to 100 krad(Si), supporting use in LEO satellite power and command systems without derating.
How is polarity marked on JANTXV1N4627D-1?
JANTXV1N4627D-1 uses a cathode band marking on the DO-35 glass body: the banded end is the cathode and must be held at a higher potential than the anode to operate in Zener breakdown. This polarity is consistent across all 1N46xx-1 series devices and is verified per MIL-STD-750 method 2026 solderability testing.
