Overview
JANTXV1N4626C-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 MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4626C-1/TR datasheet, JANTXV1N4626C-1/TR pinout, JANTXV1N4626C-1/TR application, or JANTXV1N4626C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (4 µV/√Hz), dynamic impedance (1400 Ω), temperature coefficient (+0.04%/°C upper bound), and JANTXV-level qualification for extended temperature operation.
Technical Context
This device operates as a precision shunt regulator with a nominal Zener voltage of 5.6 V at 250 mA test current, exhibiting low noise density (4 µV/√Hz) and stable regulation across –65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
The JANTXV1N4626C-1/TR delivers 5.6 V regulation with ±2% initial tolerance and a temperature coefficient bounded by –0.020%/°C to +0.040%/°C - critical for stable reference generation in analog circuits where drift must be minimized over wide operating temperatures.

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 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or repair | Select when board space is constrained and automated placement is available |
| JANTXV1N4626-1 | Identical Zener parameters but ±5% tolerance instead of ±2%; same JANTXV qualification | Acceptable where cost sensitivity outweighs precision requirement; wider voltage spread affects closed-loop accuracy | Select for non-critical regulation where ±5% tolerance meets system spec and budget is prioritized |
Compared with JANTXV1N4626C-1/TR, the 1N4626US-1 offers identical regulation performance in a compact SMT form factor but sacrifices mechanical serviceability, while JANTXV1N4626-1 trades ±2% tolerance for lower unit cost without compromising military-grade reliability.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4626C-1/TR?
JANTXV1N4626C-1/TR has a nominal Zener voltage of 5.6 V with a ±2% tolerance, measured at 250 mA test current and 25 °C ambient. This tighter tolerance enables higher accuracy in feedback networks compared to standard ±5% variants like JANTXV1N4626-1. The C suffix explicitly denotes the 2% grade.
Is JANTXV1N4626C-1/TR qualified to MIL-PRF-19500/435?
Yes, JANTXV1N4626C-1/TR is fully qualified to MIL-PRF-19500/435 at the JANTXV reliability level, including rigorous screening for temperature cycling, mechanical shock, and long-term life testing. This qualification ensures suitability for mission-critical aerospace and defense applications where failure is not an option.
What is the maximum power dissipation and derating behavior of JANTXV1N4626C-1/TR?
JANTXV1N4626C-1/TR is rated for 500 mW average power dissipation at 25 °C lead temperature. Power must be linearly derated starting at 50 °C, reaching zero at 175 °C. On a typical FR4 PCB with 4 mm² copper pads, derating begins at 25 °C ambient, ensuring safe operation across its full –65 °C to +175 °C junction temperature range.
Does JANTXV1N4626C-1/TR have low noise characteristics suitable for precision references?
Yes, JANTXV1N4626C-1/TR exhibits a noise density of 4 µV/√Hz at 250 mA, making it suitable for precision analog references. This value is significantly lower than higher-voltage Zeners in the same family and supports use in instrumentation-grade circuits without requiring external noise filtering.
What package type and marking does JANTXV1N4626C-1/TR use?
JANTXV1N4626C-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by a band. It is marked with the full part number "JANTXV1N4626C-1" and supplied in tape-and-reel format per EIA-296 (denoted by the "TR" suffix).
