Product details
Overview
JANTX1N4626C-1 from Microsemi is a 5.6 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4626C-1 datasheet, JANTX1N4626C-1 pinout, JANTX1N4626C-1 application, or JANTX1N4626C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low dynamic impedance (1400 Ω @ 250 mA), temperature coefficient (+0.04%/°C), and radiation-hardened construction for mission-critical analog reference circuits.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 5.6 V at 250 mA test current, exhibiting a positive temperature coefficient of –0.020/+0.040 %/°C - enabling stable biasing across –65 °C to +175 °C junction temperature range.
Its metallurgical bond construction ensures low noise density (4 μV/√Hz typical), minimal capacitance (~1 pF), and immunity to ESD per MIL-STD-750 Method 1020, making it suitable for low-noise analog references and radiation-tolerant systems where long-term parametric stability is required.

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 surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated assembly and board space constraints outweigh manual serviceability needs |
| JAN1N4626C-1 | Identical electrical and mechanical specs, but qualified only to JAN level (less stringent screening than JANTX) | Lacks JANTX-level burn-in, thermal cycling, and lot acceptance testing required for Class H avionics | Select only for non-safety-critical commercial or lab-use applications where full JANTX screening is not mandated |
Compared with JANTX1N4626C-1, the 1N4626US-1 offers identical regulation performance in a space-saving SMT form factor but sacrifices mechanical robustness and repairability, while the JAN1N4626C-1 reduces cost and lead time at the expense of mission-critical reliability assurance.

FAQ
What is the Zener voltage tolerance of JANTX1N4626C-1?
JANTX1N4626C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This is tighter than the standard ±5% (blank suffix) and enables higher-accuracy voltage references in precision analog circuits without trimming.
Is JANTX1N4626C-1 RoHS compliant?
No, JANTX1N4626C-1 is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4626C-1e3); JANTX-level parts retain tin-lead plating to meet MIL-STD-750 solderability requirements and avoid reliability risks associated with pure matte tin.
What does the "JANTX" prefix signify for JANTX1N4626C-1?
The "JANTX" prefix indicates that JANTX1N4626C-1 is qualified to the JANTX level per MIL-PRF-19500/435, including extended environmental screening (thermal cycling, burn-in, and lot acceptance tests) beyond JAN level - required for Class H and Class K military applications.
What is the maximum Zener current IZM for JANTX1N4626C-1?
The maximum Zener current IZM for JANTX1N4626C-1 is 65 mA, calculated from its 500 mW power rating and 5.6 V nominal Zener voltage (IZM = PM(AV)/VZ). Derating begins linearly above 50 °C case temperature, reaching zero at 175 °C.
How is polarity marked on JANTX1N4626C-1?
JANTX1N4626C-1 uses a cathode band marking on the glass body - the banded end is the cathode and must be connected to the more positive potential during Zener regulation. This axial-leaded DO-35 package follows JEDEC-standard polarity identification.
