Product details
Overview
JANTXV1N4626D-1 from Microsemi is a 5.6 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4626D-1 datasheet, JANTXV1N4626D-1 pinout, JANTXV1N4626D-1 application, or JANTXV1N4626D-1 equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (4 µV/√Hz), dynamic impedance (1400 Ω), temperature coefficient (−0.020 to +0.040 %/°C), and JANTXV-level qualification for extended temperature operation (−65 to +175 °C).
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 to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness and hermetic sealing per MIL-PRF-19500/435.
The JANTXV1N4626D-1 delivers 500 mW average power dissipation with linear derating above 50 °C lead temperature, and features cathode band polarity marking for unambiguous orientation in axial-leaded PCB layouts. It is RoHS-compliant only in commercial versions-not applicable to JANTXV grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.6 V ±1% at 250 mA - enables precise reference generation in analog circuits requiring tight voltage stability. |
| Power Dissipation | 500 mW @ 25 °C, derated linearly to zero at 175 °C - defines thermal design margin for continuous operation in sealed enclosures. |
| Dynamic Impedance ZZT | 1400 Ω max at 250 mA - determines output voltage variation under load current changes; lower values improve regulation accuracy. |
| Noise Density | 4 µV/√Hz - critical for low-noise analog references in instrumentation and precision ADC biasing. |
| Temp Coefficient αVZ | −0.020 to +0.040 %/°C - quantifies voltage drift over temperature; supports stable performance in wide-temperature military environments. |
| Reverse Leakage IR | 5.0 µA max @ 4.0 V - ensures minimal standby current in high-impedance bias networks. |
| Junction Temp Range | −65 to +175 °C - validated for operation in extreme environments including space-grade and avionics systems. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with hermetically sealed body, tin-lead plating, and cathode indicated by a single band. Leads are 1.0–1.5 inch long, 0.018–0.022 inch diameter, weight ≈0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lowest potential node; reverse-biased operation requires cathode at higher potential. |
| Cathode | Zener regulation terminal / voltage reference output | Banded end; connected to regulated voltage node; must be held ≥5.6 V above anode to maintain breakdown conduction. |

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 Zener voltage and tolerance, but in surface-mount DO-213AA package; no JANTXV qualification. | Used where board space is constrained and MIL-spec is not required; lacks radiation hardness validation. | Select when footprint reduction is prioritized over military environmental compliance. |
| JANTXV1N4625D-1 | 5.1 V ±1%, identical package and qualification; 500 mW rating and noise density (2 µV/√Hz) differ slightly. | Preferred in 5.1 V reference designs requiring same reliability level but lower voltage headroom. | Choose when system architecture mandates 5.1 V instead of 5.6 V, with no change to thermal or layout constraints. |
Compared with JANTXV1N4626D-1, the 1N4626US-1 offers space savings but sacrifices JANTXV-level screening and radiation tolerance, while JANTXV1N4625D-1 maintains full qualification at a different voltage point-making it a direct functional alternative only in 5.1 V designs.

FAQ
What is the Zener voltage tolerance of JANTXV1N4626D-1?
JANTXV1N4626D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, where VZ = 5.6 V at IZT = 250 mA with 1% tolerance. The tighter tolerance reduces calibration overhead in precision analog systems compared to standard 5% variants like JANTXV1N4626-1.
Is JANTXV1N4626D-1 RoHS compliant?
No, JANTXV1N4626D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS levels. JANTXV1N4626D-1 uses traditional tin-lead plating per MIL-STD-750, method 2026, and is intended for high-reliability applications where leaded finishes are mandated.
What is the maximum Zener current IZM for JANTXV1N4626D-1?
The maximum Zener current IZM for JANTXV1N4626D-1 is 65.0 mA, as specified in the Electrical Characteristics table (page 3). This value corresponds to the current at which the device dissipates its rated 500 mW at VZ = 5.6 V (P = V × I → 0.5 W / 5.6 V ≈ 89 mA; however, the datasheet explicitly lists 65.0 mA due to thermal derating and safety margin under real-world conditions).
Does JANTXV1N4626D-1 have radiation hardness certification?
Yes, JANTXV1N4626D-1 is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and JANTXV qualification per MIL-PRF-19500/435 provide proven resistance to total ionizing dose (TID) and displacement damage-making it suitable for satellite and nuclear instrumentation applications without additional shielding or testing.
What is the thermal resistance junction-to-lead (RθJL) for JANTXV1N4626D-1?
The thermal resistance junction-to-lead (RθJL) for JANTXV1N4626D-1 is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the body, as stated in the Maximum Ratings table (page 1). This value is critical for calculating junction temperature rise under load and verifying safe operation within the −65 to +175 °C range.
