It delivers stable voltage regulation in high-reliability military power supply and reference circuits.
For engineers reviewing the JANTXV1N4616C-1/TR datasheet, JANTXV1N4616C-1/TR pinout, JANTXV1N4616C-1/TR application, or JANTXV1N4616C-1/TR equivalent, key selection factors include its MIL-qualified reliability grade, low-noise performance (1 µV/√Hz), tight 2% voltage tolerance, and thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures mechanical robustness and long-term stability under thermal cycling and radiation exposure.
It exhibits a negative temperature coefficient of –0.075 %/°C and supports regulation across 1.0–100 mA operating current range while maintaining ≤1300 Ω dynamic impedance at IZT = 250 mA and ≤2.0 µA IR at VR = 1.0 V.

FAQ
What is the Zener voltage tolerance of JANTXV1N4616C-1/TR?
JANTXV1N4616C-1/TR has a nominal Zener voltage of 2.2 V with a ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tighter tolerance is verified per MIL-PRF-19500/435 screening and supports precision regulation where standard ±5% devices would introduce unacceptable error.
Is JANTXV1N4616C-1/TR RoHS compliant?
No, JANTXV1N4616C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANTXV1N4616C-1/TR uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum reverse leakage current for JANTXV1N4616C-1/TR?
The maximum reverse leakage current (IR) for JANTXV1N4616C-1/TR is 2.0 µA at VR = 1.0 V and 25 °C, as specified in the Electrical Characteristics table. This low leakage supports efficient operation in battery-powered or ultra-low-power regulation circuits where standby current must be minimized.
How does the thermal derating of JANTXV1N4616C-1/TR work?
JANTXV1N4616C-1/TR has a rated average power dissipation of 500 mW at 25 °C, linearly derated to zero at +175 °C junction temperature. Derating begins at +50 °C lead temperature per Figure 2; on a typical FR4 board, it starts at +25 °C ambient and follows a straight-line slope to zero at +175 °C, requiring thermal pad design and airflow consideration above 50 °C.
Can JANTXV1N4616C-1/TR be used in radiation-exposed environments?
Yes, JANTXV1N4616C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic package provide proven resilience to total ionizing dose (TID), making it suitable for satellite payloads, nuclear instrumentation, and other high-radiation applications without additional shielding or derating.
