FAQ
What is the Zener voltage and tolerance of JANTXV1N4622D-1?
JANTXV1N4622D-1 has a nominal Zener voltage of 3.9 V with a tight ±1% tolerance at 250 mA test current. This specification is guaranteed under MIL-PRF-19500/435 JANTXV screening and remains stable across its full –65 to +175 °C junction temperature range. The 1% tolerance eliminates need for post-manufacture calibration in high-accuracy reference designs.
Is JANTXV1N4622D-1 suitable for space applications?
Yes - JANTXV1N4622D-1 is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to MIL-PRF-19500/435 JANTXV level, making it suitable for low-Earth orbit (LEO) missions. Its hermetic DO-35 glass package and metallurgical bond construction prevent parametric degradation under total ionizing dose (TID) exposure, a key requirement for spacecraft power and telemetry subsystems.
What is the maximum power dissipation and derating behavior of JANTXV1N4622D-1?
JANTXV1N4622D-1 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 board with 1 oz copper, derating begins at 25 °C ambient. This behavior is documented in Figure 2 of the T4-LDS-0245-2 datasheet and directly impacts thermal design of high-density military PCBs.
Does JANTXV1N4622D-1 have low noise characteristics?
Yes - JANTXV1N4622D-1 delivers an exceptionally low noise density of 1 µV/√Hz at 250 mA, measured in the 1–3 kHz band. This performance is confirmed in the Electrical Characteristics table and Figure 1 of the datasheet, making JANTXV1N4622D-1 ideal for low-noise analog references in precision instrumentation and RF bias networks.
What packaging and marking does JANTXV1N4622D-1 use?
JANTXV1N4622D-1 uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by a visible band. It is marked with the full part number "JANTXV1N4622D-1" and conforms to MIL-STD-750 solderability requirements. Lead finish is tin-lead per standard; RoHS versions are not offered for JANTXV-grade parts.
