Product details
Overview
JANTX1N4627C-1 from Microsemi is a 500 mW, 6.2 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% voltage tolerance, 1200 Ω dynamic impedance at 250 mA test current, and maximum noise density of 5 µV/√Hz - used for precision voltage reference and regulation in military power supply monitoring circuits.
For engineers reviewing the JANTX1N4627C-1 datasheet, JANTX1N4627C-1 pinout, JANTX1N4627C-1 application, or JANTX1N4627C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (250 °C/W junction-to-lead), noise density (5 µV/√Hz), and MIL-qualified reliability level - all critical for high-reliability analog reference design.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded construction for enhanced stability and radiation hardness. It delivers stable 6.2 V regulation across 5–61 mA operating current range and supports operation from –65 °C to +175 °C junction temperature.
The diode exhibits a temperature coefficient of –0.010 to +0.050 %/°C and maintains low capacitance (<2 pF typical) and minimal ESD sensitivity per MIL-STD-750 Method 1020 - enabling use in low-noise, high-temperature analog signal conditioning and reference circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4627US-1 | Same 6.2 V ±2%, but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy repair | Select when board space constraints mandate SMT or automated placement is required |
| JAN1N4627C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN (not JANTX) level per MIL-PRF-19500/435 | Limited to less demanding reliability requirements; not approved for flight hardware or critical subsystems | Select only for cost-sensitive non-flight prototypes where full JANTX screening is unnecessary |
Compared with JANTX1N4627C-1, the 1N4627US-1 offers identical regulation performance in a space-saving SMT form factor, while the JAN1N4627C-1 provides same-package compatibility at reduced reliability assurance - enabling trade-offs between footprint, screening depth, and lifecycle support.

FAQ
What is the Zener voltage tolerance of JANTX1N4627C-1?
JANTX1N4627C-1 has a nominal Zener voltage of 6.2 V with a tolerance of ±2%, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed over the full operating temperature range and qualifies the device for precision reference applications where tighter regulation than standard ±5% parts is required. The JANTX1N4627C-1 achieves this via tighter binning and screening during MIL-PRF-19500/435 qualification.
Is JANTX1N4627C-1 suitable for high-temperature environments?
Yes, JANTX1N4627C-1 is rated for junction temperatures from –65 °C to +175 °C and features a thermal resistance of 250 °C/W junction-to-lead (with 3/8″ lead length). Its metallurgically bonded glass DO-35 construction ensures stable parametric performance across extreme thermal cycles, making it suitable for downhole drilling tools, jet engine controllers, and satellite power systems where ambient temperatures exceed 125 °C.
Does JANTX1N4627C-1 meet RoHS requirements?
No, JANTX1N4627C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only on commercial-grade variants, not on JANTX-qualified parts. The JANTX1N4627C-1 uses traditional tin-lead plating per MIL-STD-750 and is intended for applications where military specifications and proven reliability supersede RoHS compliance.
What is the maximum Zener current (IZM) for JANTX1N4627C-1?
The maximum Zener current IZM for JANTX1N4627C-1 is 61.0 mA, derived from its 500 mW power rating and 6.2 V nominal Zener voltage (P = V × I → I = 0.5 W / 6.2 V ≈ 80.6 mA, derated to 61 mA per datasheet Table on Page 3). This value reflects safe continuous operation at 25 °C lead temperature, with linear derating to zero at +175 °C.
How does the noise performance of JANTX1N4627C-1 compare to lower-voltage Zeners in the same family?
JANTX1N4627C-1 has a maximum noise density of 5 µV/√Hz at its 250 mA test current, consistent with the trend for 6.2 V Zeners in the 1N46xx series. Lower-voltage parts (e.g., 1N4614–1N4620) exhibit higher noise (up to 3.5 µV/√Hz), while higher-voltage devices (>6.8 V) show increased noise (e.g., 40 µV/√Hz at 6.8 V). This makes JANTX1N4627C-1 among the lowest-noise options in its voltage class for precision analog references.
