For engineers reviewing the JANTXV1N4622D-1/TR datasheet, JANTXV1N4622D-1/TR pinout, JANTXV1N4622D-1/TR application, or JANTXV1N4622D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and MIL-PRF-19500/435 qualification details required for radiation-hardened, low-noise analog reference design.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 3.9 V at 250 mA test current, exhibiting a temperature coefficient of –0.060 %/°C and dynamic impedance of 1650 Ω at IZT. Its metallurgical bond ensures stable junction behavior under thermal cycling and radiation exposure.
Designed for high-reliability environments, JANTXV1N4622D-1/TR meets JANTXV level per MIL-PRF-19500/435, supports operation from –65 °C to +175 °C, and delivers low noise density (1 µV/√Hz) due to its low-voltage Zener structure and hermetically sealed DO-35 package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4622US-1/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT assembly; eliminates lead inductance for higher-frequency stability | Select when board space is constrained and reflow compatibility is required |
| JANTXV1N4621D-1/TR | 3.6 V nominal Zener voltage; identical tolerance, power, and qualification level | Used where slightly lower reference voltage improves headroom in 5 V rail monitoring | Select when 3.6 V reference better matches system margin requirements |
Compared with JANTXV1N4622D-1/TR, the DO-213AA alternative enables miniaturized layouts but sacrifices through-hole serviceability, while the 3.6 V variant trades 0.3 V headroom for tighter regulation at lower currents-both retain JANTXV screening and metallurgical bond integrity.

FAQ
What is the Zener voltage tolerance for JANTXV1N4622D-1/TR?
JANTXV1N4622D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in the part number. This is confirmed in the nomenclature table on page 2 of Microsemi's T4-LDS-0245-2 datasheet, where "D = 1%" is explicitly defined. The device delivers 3.9 V ±1% at 250 mA test current under standard conditions.
Is JANTXV1N4622D-1/TR qualified to JANTXV level per MIL-PRF-19500/435?
Yes, JANTXV1N4622D-1/TR is fully qualified to JANTXV level per MIL-PRF-19500/435, as stated in the "Qualified Levels" section on page 1 and reinforced in the "PART NOMENCLATURE" table. The "JANTXV" prefix in the part number directly indicates compliance with the highest screening tier for reliability and environmental testing among the JAN family.
What is the maximum Zener impedance of JANTXV1N4622D-1/TR and at what condition is it specified?
The maximum Zener impedance (ZZT) of JANTXV1N4622D-1/TR is 1650 Ω, measured at the Zener test current IZT of 250 mA, as shown in the Electrical Characteristics table on page 3. This value reflects small-signal AC impedance under 10% rms modulation at 60 Hz, per Note 2 in the same datasheet.
Does JANTXV1N4622D-1/TR have radiation hardness certification?
Yes, JANTXV1N4622D-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050 referenced on page 1. Its metallurgically bonded DO-35 construction and JANTXV qualification provide proven tolerance to total ionizing dose (TID) and displacement damage, making it suitable for space and nuclear environments without additional shielding.
What is the noise density performance of JANTXV1N4622D-1/TR and how is it measured?
JANTXV1N4622D-1/TR exhibits a maximum noise density of 1 µV/√Hz, specified at IZT = 250 mA and 25 °C ambient, per the Electrical Characteristics table. Measurement uses a 1 kHz–3 kHz bandpass filter (Figure 1), confirming suitability for low-noise analog references where broadband voltage noise must be minimized.
