Product details
Overview
JANTX1N4627D-1 from Microsemi is a 1% tolerance, 6.2 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4627D-1 datasheet, JANTX1N4627D-1 pinout, JANTX1N4627D-1 application, or JANTX1N4627D-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification details required for precision analog reference and overvoltage protection design.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, delivering stable 6.2 V regulation at 250 mA test current (IZT). Its metallurgical bond construction ensures low noise (5 µV/√Hz typical) and radiation hardness per MicroNote 050.
It exhibits a ±0.010/+0.050 %/°C temperature coefficient (αVZ), enabling predictable drift compensation in wide-temperature-range circuits. Dynamic impedance is 1200 Ω at IZT, supporting low-impedance voltage reference applications when used with appropriate series resistance.

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 6.2 V, 1% tolerance, but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting | Select when board space is constrained and automated placement is available |
| JAN1N4627D-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (lower screening than JANTX) | Lacks JANTX-level burn-in and environmental stress screening; not approved for Class H or Class K programs | Select only for non-critical commercial-aerospace subsystems with relaxed reliability requirements |
Compared with JANTX1N4627D-1, the 1N4627US-1 offers identical regulation performance in a compact SMT form factor but sacrifices mechanical robustness and hand-solderability, while the JAN1N4627D-1 reduces cost and screening rigor at the expense of mission-critical reliability assurance.

FAQ
What is the Zener voltage and tolerance of JANTX1N4627D-1?
JANTX1N4627D-1 has a nominal Zener voltage of 6.2 V with ±1% tolerance at 250 mA test current (IZT), measured under thermal equilibrium at 25 °C ambient. This tight tolerance is achieved via post-process binning and is guaranteed per MIL-PRF-19500/435 JANTX screening requirements.
Is JANTX1N4627D-1 RoHS compliant?
No, JANTX1N4627D-1 is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions (e.g., 1N4627D-1e3); JANTX-level parts retain tin-lead plating per MIL-STD-750 for solderability and reliability in high-reliability applications.
What is the maximum power dissipation and derating behavior of JANTX1N4627D-1?
JANTX1N4627D-1 is rated for 500 mW average power dissipation at 25 °C lead temperature. Power must be linearly derated starting at 50 °C lead temperature, reaching zero at 175 °C. On a typical FR4 board, derating begins at 25 °C ambient, following the curve in Figure 2 of T4-LDS-0245-2.
Does JANTX1N4627D-1 have radiation hardness certification?
Yes, JANTX1N4627D-1 is inherently radiation hard per Microsemi MicroNote 050 due to its metallurgically bonded structure and glass encapsulation. It is widely used in space-grade applications where total ionizing dose (TID) immunity up to 100 krad(Si) is required without additional shielding.
What is the noise density specification for JANTX1N4627D-1 and how is it measured?
JANTX1N4627D-1 has a maximum noise density of 5 µV/√Hz at 250 mA Zener test current (IZT), measured using a 1 kHz–3 kHz bandpass filter per Figure 1 in T4-LDS-0245-2. This low noise supports high-resolution analog reference applications where broadband interference must be minimized.
