Product details
Overview
JANTX1N4627D-1/TR from Microsemi is a 1% tolerance, 6.2 V, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JANTX1N4627D-1/TR datasheet, JANTX1N4627D-1/TR pinout, JANTX1N4627D-1/TR application, or JANTX1N4627D-1/TR equivalent, key selection factors include its 1% Zener voltage tolerance, 5 µA maximum reverse leakage at 5.0 V, 1200 Ω dynamic impedance at 250 mA test current, and radiation-hardened construction for mission-critical analog subsystems.
Technical Context
This device operates as a two-terminal voltage reference in reverse-bias breakdown mode, with cathode band marking polarity. Its metallurgical bond ensures stable thermal performance across -65 °C to +175 °C junction temperature range and low noise density (5 µV/√Hz typical at 6.2 V).
Designed for military-grade reliability, JANTX1N4627D-1/TR meets MIL-PRF-19500/435 requirements with full traceability, hermetic glass sealing, and ESD immunity per MIL-STD-750 Method 1020 - enabling use in regulated power supplies where long-term stability under thermal cycling and radiation exposure is mandatory.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4627D-1 | Higher screening level (JANTXV vs JANTX); tighter parametric limits on ZZT and αVZ. | Required for programs specifying MIL-PRF-19500/435 Class V testing (vibration, thermal shock, burn-in). | Select when full JANTXV qualification is mandated by system-level reliability specs. |
| 1N4627US-1TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Used where PCB real estate is constrained and automated SMT assembly is preferred over through-hole. | Choose for high-density layouts or reflow-only production; not mechanically interchangeable. |
Compared with JANTX1N4627D-1/TR, JANTXV1N4627D-1 offers enhanced screening for extreme environmental stress, while 1N4627US-1TR provides identical regulation performance in a space-saving SMT form factor - neither is pin-compatible due to differing packages and mechanical interfaces.

FAQ
What is the Zener voltage tolerance for JANTX1N4627D-1/TR?
JANTX1N4627D-1/TR has a nominal Zener voltage of 6.2 V with a guaranteed tolerance of ±1%, as indicated by the "D" suffix in the part number per MIL-PRF-19500/435 nomenclature. This tolerance is verified under standard test conditions at 25 °C with 250 mA Zener test current and applies across the full qualified temperature range when used within rated power limits.
Is JANTX1N4627D-1/TR RoHS compliant?
No, JANTX1N4627D-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4627D-1e3); military-grade variants like JANTX1N4627D-1/TR retain tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements to maintain solderability and reliability in high-reliability applications.
What is the maximum reverse leakage current for JANTX1N4627D-1/TR?
The maximum reverse leakage current (IR) for JANTX1N4627D-1/TR is 5.0 µA at 5.0 V reverse voltage, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This value is measured at 25 °C and reflects worst-case leakage under sub-breakdown conditions before regulation onset.
Can JANTX1N4627D-1/TR be used in surface-mount designs?
No, JANTX1N4627D-1/TR uses a DO-35 axial-leaded glass package intended for through-hole mounting. For surface-mount equivalents, Microsemi offers the 1N4627US-1TR in DO-213AA package - same electrical specs but incompatible mechanical form factor. Direct substitution requires PCB redesign.
What does the "TR" suffix mean in JANTX1N4627D-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTX1N4627D-1/TR contains the same die, qualification, and electrical characteristics as JANTX1N4627D-1, differing only in packaging format - no performance or reliability changes are introduced by the TR suffix.
