Product details
Overview
JANTXV1N4627C-1 from Microsemi is a 500 mW, 6.2 V ±2% 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 JANTXV1N4627C-1 datasheet, JANTXV1N4627C-1 pinout, JANTXV1N4627C-1 application, or JANTXV1N4627C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (5 µV/√Hz), dynamic impedance (1200 Ω), temperature coefficient (–0.010 to +0.050 %/°C), and hermetic DO-35 packaging for harsh-environment stability.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 6.2 V at 250 mA test current, exhibiting low noise density (5 µV/√Hz) and tightly controlled temperature coefficient (–0.010 to +0.050 %/°C) for stable reference performance across –65 °C to +175 °C junction temperature range.
Its metallurgical bond construction ensures mechanical robustness and radiation hardness per Microsemi MicroNote 050, while the DO-35 axial-leaded glass package provides hermetic sealing and ESD immunity per MIL-STD-750 method 1020 - critical for military-grade analog signal conditioning and power rail stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V ±2% at IZT = 250 mA - enables precise 6.2 V reference generation with minimal calibration drift. |
| Power Dissipation | 500 mW at TC = 25 °C, derated linearly to zero at 175 °C - supports continuous operation in high-temperature avionics enclosures. |
| Dynamic Impedance ZZT | 1200 Ω max at IZT = 250 mA - ensures stable regulation under varying load currents without significant output voltage sag. |
| Noise Density | 5 µV/√Hz at IZT = 250 mA - suitable for low-noise analog references in precision instrumentation and ADC biasing. |
| Temp Coefficient αVZ | –0.010 to +0.050 %/°C - minimizes thermal drift in wide-temperature-range applications like satellite power systems. |
| Reverse Leakage IR | 5.0 µA max at VR = 5.0 V - guarantees low standby current in battery-backed reference circuits. |

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 electrical specs but in surface-mount DO-213AA package; no axial leads. | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when board space is constrained and automated assembly is used. |
| JANTXV1N4627D-1 | Identical construction and package, but tighter ±1% Zener voltage tolerance. | Higher cost and longer lead time; justified only where <±62 mV absolute reference accuracy is mandated. | Select only if system-level calibration budget requires sub-1% initial tolerance. |
Compared with JANTXV1N4627C-1, the JANTXV1N4627D-1 offers improved initial accuracy at higher cost and longer procurement cycle, while the 1N4627US-1 enables miniaturization at the expense of mechanical robustness and hand-soldering flexibility.

FAQ
What is the Zener voltage tolerance of JANTXV1N4627C-1?
JANTXV1N4627C-1 has a nominal Zener voltage of 6.2 V with a tolerance of ±2%, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed at 25 °C with IZT = 250 mA and applies across the full qualified temperature range when combined with its specified temperature coefficient of –0.010 to +0.050 %/°C.
Is JANTXV1N4627C-1 RoHS compliant?
No, JANTXV1N4627C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements and maintain legacy qualification integrity.
What is the maximum power dissipation of JANTXV1N4627C-1 at 100 °C lead temperature?
At 100 °C lead temperature, JANTXV1N4627C-1 is rated for approximately 333 mW. Its 500 mW rating linearly derates from 25 °C, reaching zero at 175 °C - calculated as 500 mW × (1 – (100 – 25)/150) = 333 mW, consistent with Figure 2 in the T4-LDS-0245-2 datasheet.
Does JANTXV1N4627C-1 require external heat sinking?
No, JANTXV1N4627C-1 does not require external heat sinking under typical conditions. With RθJL = 250 °C/W and a 500 mW rating, self-heating at full power raises junction temperature by 125 °C above lead temperature - manageable within its –65 °C to +175 °C range when leads are mounted per JEDEC standards (3/8″ length, FR4 board).
How is polarity marked on JANTXV1N4627C-1?
JANTXV1N4627C-1 uses a cathode band marking on the DO-35 glass body: the banded end is the cathode and must be connected to the higher-potential node for Zener regulation. The opposite (unbanded) end is the anode and connects to system ground or the lower-potential rail - correct orientation is essential to avoid forward conduction damage.
