Product details
Overview
JANTXV1N4626C-1 from Microsemi is a 5.6 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 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 datasheet, JANTXV1N4626C-1 pinout, JANTXV1N4626C-1 application, or JANTXV1N4626C-1 equivalent, key selection criteria include Zener voltage tolerance (2%), noise density (4 μV/√Hz), dynamic impedance (1400 Ω), temperature coefficient (+0.040%/°C max), and JANTXV-level radiation-hardened qualification.
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 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 JANTXV qualification mandates screening per MIL-PRF-19500/435, including burn-in, temperature cycling, and hermeticity testing. It delivers 5.6 V regulation with ±2% tolerance and a temperature coefficient bounded by -0.020%/°C to +0.040%/°C - critical for stable reference generation in analog signal chains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4626UR-1 | Same electrical specs, but DO-213AA surface-mount package instead of DO-35 axial lead | Requires PCB re-layout; suited for automated SMT assembly and space-constrained modules | Select when board area is constrained and reflow compatibility is required |
| 1N4626US-1 | Commercial-grade (non-military) version with same 5.6 V/2% specs but no MIL-PRF screening | Lacks JANTXV radiation hardness and extended temperature screening; limited to benign environments | Select for cost-sensitive ground-test equipment where full qualification is unnecessary |
Compared with JANTXV1N4626C-1, the JANTXV1N4626UR-1 offers identical regulation performance in a surface-mount form factor-enabling higher-density layouts-while the 1N4626US-1 provides functional equivalence at lower cost but without military-grade reliability assurance.
