Product details
Overview
JANTX1N4626C-1/TR from Microsemi is a 5.6 V, ±2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to JANTX level per MIL-PRF-19500/435, used for precision voltage regulation in military-grade power supply reference and analog signal conditioning circuits.
For engineers reviewing the JANTX1N4626C-1/TR datasheet, JANTX1N4626C-1/TR pinout, JANTX1N4626C-1/TR application, or JANTX1N4626C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), low dynamic impedance (1400 Ω @ 250 mA), temperature coefficient (+0.040%/°C max), noise density (4 μV/√Hz), and MIL-qualified reliability for high-stability DC biasing and reference generation.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 5.6 V at 250 mA test current, exhibiting a maximum dynamic impedance of 1400 Ω and a temperature coefficient ranging from –0.020%/°C to +0.040%/°C. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation across –65°C to +175°C junction temperature range, it delivers 500 mW average power dissipation with linear derating above 50°C lead temperature and maintains ≤5.0 μA reverse leakage at 4.0 V. The cathode band marking defines polarity for proper orientation in series-shunt regulation topologies.
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 |
|---|---|---|---|
| 1N4626US-1/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated placement is available |
| JANTXV1N4626C-1/TR | Identical electrical parameters with enhanced screening (JANTXV level); higher burn-in and lot acceptance test rigor | Required for mission-critical subsystems where failure probability must be <10–6 per hour | Select when system FMEA mandates extended reliability validation beyond JANTX |
Compared with JANTX1N4626C-1/TR, the JANTXV variant adds screening for extreme reliability assurance while the US version trades axial mounting for SMT compatibility-neither is pin-compatible due to differing packages, making them functional alternatives rather than drop-in replacements.

FAQ
What is the Zener voltage tolerance for JANTX1N4626C-1/TR?
JANTX1N4626C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance applies at 25°C with 250 mA test current and ensures tight regulation for precision reference applications where post-production trimming is impractical.
Is JANTX1N4626C-1/TR RoHS compliant?
No, JANTX1N4626C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS reliability levels. JANTX1N4626C-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum reverse leakage current for JANTX1N4626C-1/TR?
The maximum reverse leakage current for JANTX1N4626C-1/TR is 4.0 μA at 4.0 V reverse voltage and 25°C, as specified in the Electrical Characteristics table. This low leakage supports energy-efficient operation in always-on monitoring circuits and extends battery life in portable military equipment using JANTX1N4626C-1/TR.
Can JANTX1N4626C-1/TR be used in surface-mount designs?
No, JANTX1N4626C-1/TR is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is not suitable for surface-mount assembly. For SMT equivalents, consider the JANTX1N4626C-1/TR's counterpart in DO-213AA package: 1N4626US-1/TR, which shares identical electrical specs but requires different footprint and reflow profile.
What does the "TR" suffix mean in JANTX1N4626C-1/TR?
The "TR" suffix in JANTX1N4626C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. It does not affect electrical performance or reliability level-JANTX1N4626C-1/TR retains full JANTX qualification and all specifications listed in Microsemi's T4-LDS-0245-2 datasheet.
