Product details
Overview
JANTX1N4627-1/TR from Microsemi is a 500 mW, 6.2 V metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435, with ±1% voltage tolerance, 1200 Ω dynamic impedance at 250 mA, and max noise density of 5 µV/√Hz - used for precision voltage reference and regulation in military-grade power supplies and analog front-ends.
For engineers reviewing the JANTX1N4627-1/TR datasheet, JANTX1N4627-1/TR pinout, JANTX1N4627-1/TR application, or JANTX1N4627-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (5 µV/√Hz), MIL-qualified reliability, thermal resistance (250 °C/W junction-to-lead), and axial-leaded DO-35 mechanical compatibility.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 6.2 V at 250 mA test current, exhibiting a temperature coefficient of –0.010 to +0.050 %/°C and dynamic impedance of 1200 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for high-reliability environments, JANTX1N4627-1/TR maintains regulation across –65 °C to +175 °C junction temperature range, supports 500 mW average power dissipation (derated linearly above 50 °C), and delivers low capacitance (<2 pF typical) and ESD immunity per MIL-STD-750 method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V ±1% at 250 mA - enables precise reference generation in analog circuits requiring tight voltage stability. |
| Power Dissipation | 500 mW @ 25 °C lead temp - supports continuous regulation in compact, unheatsinked axial-mount designs. |
| Dynamic Impedance ZZT | 1200 Ω @ 250 mA - determines output voltage variation under load changes; critical for low-drift reference applications. |
| Noise Density | 5 µV/√Hz @ 250 mA - specifies broadband RMS noise contribution; essential for low-noise instrumentation and ADC reference design. |

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. | Used where PCB space constraints or automated assembly require SMT mounting instead of through-hole. | Select 1N4627US-1 only when board layout mandates SMT; JANTX1N4627-1/TR remains preferred for manual repair, high-vibration, or legacy through-hole designs. |
| JANTXV1N4627-1 | Identical electrical parameters but qualified to higher JANTXV level per MIL-PRF-19500/435, including extended temperature screening and additional life testing. | Required for programs specifying JANTXV or JANS reliability levels (e.g., flight-critical avionics). | Choose JANTXV1N4627-1 if program spec mandates JANTXV screening; otherwise JANTX1N4627-1/TR satisfies most JANTX-tier requirements at lower cost. |
Compared with 1N4627US-1 and JANTXV1N4627-1, JANTX1N4627-1/TR offers optimal balance of MIL-qualified reliability, axial-leaded serviceability, and cost for non-flight-critical defense electronics - delivering verified 6.2 V ±1% regulation with 5 µV/√Hz noise in hermetic DO-35 packaging.

FAQ
What is the Zener voltage tolerance of JANTX1N4627-1/TR?
JANTX1N4627-1/TR has a Zener voltage tolerance of ±1%, specified per the "D" suffix in its nomenclature and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This tight tolerance enables direct use as a precision reference without external trimming in JANTX-level systems.
Is JANTX1N4627-1/TR RoHS compliant?
No - JANTX1N4627-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e3 suffix) are available only for commercial-grade parts; JANTX-level devices retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements.
What is the maximum Zener current IZM for JANTX1N4627-1/TR?
The maximum Zener current IZM for JANTX1N4627-1/TR is 61.0 mA, as listed in the Electrical Characteristics table. This value corresponds to the current at which the device reaches its 500 mW power limit at 6.2 V, assuming ideal thermal conditions.
Does JANTX1N4627-1/TR have radiation hardness certification?
Yes - JANTX1N4627-1/TR is inherently radiation hard as described in Microsemi MicroNote 050, a documented characteristic of its metallurgically bonded glass construction. It is widely used in satellite payloads where total ionizing dose (TID) resilience is required.
What does the "TR" suffix indicate in JANTX1N4627-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and is explicitly noted in the Mechanical and Packaging section of the datasheet.
