Product details
Overview
JANTXV1N4622C-1/TR from Microsemi is a 3.9 V, 2% tolerance, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, metallurgically bonded for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4622C-1/TR datasheet, JANTXV1N4622C-1/TR pinout, JANTXV1N4622C-1/TR application, or JANTXV1N4622C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), low dynamic impedance (1650 Ω @ 250 mA), temperature coefficient (−0.060 %/°C), and MIL-PRF-19500/435 JANTXV qualification for harsh-environment operation.
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 negative temperature coefficient of −0.060 %/°C - enabling stable reference generation across −65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures low noise density (1 µV/√Hz) and radiation hardness per MicroNote 050.
The JANTXV1N4622C-1/TR is rated for 500 mW average power dissipation at 25 °C, derating linearly to zero at 175 °C, with thermal resistance junction-to-lead of 250 °C/W at 10 mm lead length. It features hermetically sealed glass DO-35 packaging and cathode band polarity marking per MIL-STD-750.

FAQ
What is the Zener voltage tolerance of JANTXV1N4622C-1/TR?
JANTXV1N4622C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its nomenclature. This means its nominal 3.9 V Zener voltage falls within 3.822 V to 3.978 V at 250 mA test current and 25 °C ambient, meeting tight regulation requirements for military-grade reference circuits.
Is JANTXV1N4622C-1/TR qualified to MIL-PRF-19500/435?
Yes, JANTXV1N4622C-1/TR is qualified to MIL-PRF-19500/435 at the JANTXV reliability level, confirming full compliance with screening, testing, and documentation requirements for high-reliability applications including aerospace and defense electronics.
What is the maximum power dissipation of JANTXV1N4622C-1/TR at 100 °C lead temperature?
At 100 °C lead temperature, JANTXV1N4622C-1/TR's maximum power dissipation is 333 mW. This is derived from linear derating starting at 500 mW at 25 °C, decreasing by 4.17 mW/°C up to 175 °C, per Figure 2 in the T4-LDS-0245-2 datasheet.
Does JANTXV1N4622C-1/TR have radiation hardness certification?
Yes, JANTXV1N4622C-1/TR exhibits inherent radiation hardness due to its metallurgical bond construction, as documented in Microsemi MicroNote 050. While not individually tested per MIL-STD-883, its process and structure provide proven resilience against total ionizing dose (TID) in space environments.
What is the cathode marking convention for JANTXV1N4622C-1/TR?
JANTXV1N4622C-1/TR uses a black band on the glass body to indicate the cathode terminal. The diode must be reverse-biased - i.e., the banded end connected to the higher-potential node - to operate in Zener regulation mode, delivering 3.9 V to the anode-side load.
