For engineers reviewing the JANTX1N4616D-1/TR datasheet, JANTX1N4616D-1/TR pinout, JANTX1N4616D-1/TR application, or JANTX1N4616D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), low noise density (1 µV/√Hz), MIL-spec qualification level, thermal resistance (250 °C/W junction-to-lead), and hermetic DO-35 packaging for harsh-environment stability.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 2.2 V at 250 mA test current, exhibiting a temperature coefficient of –0.075 %/°C and dynamic impedance of 1300 Ω at IZT. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for military-grade reliability, JANTX1N4616D-1/TR supports operation from –65 °C to +175 °C, with reverse leakage limited to ≤2.0 µA at VR = 1.0 V and maximum Zener current of 100 mA. It delivers minimal capacitance and ESD insensitivity per MIL-STD-750 method 1020.

FAQ
What is the Zener voltage tolerance of JANTX1N4616D-1/TR?
JANTX1N4616D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This tight tolerance ensures initial accuracy of 2.2 V ±0.022 V at 250 mA test current, critical for uncalibrated reference designs in defense electronics where post-manufacture trimming is impractical.
Is JANTX1N4616D-1/TR RoHS compliant?
No, JANTX1N4616D-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4616D-1e3); MIL-spec variants like JANTX1N4616D-1/TR retain tin-lead plating per MIL-STD-750 to ensure solder joint reliability under thermal cycling and mechanical stress in high-reliability applications.
What does the "TR" suffix mean in JANTX1N4616D-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-volume manufacturing. JANTX1N4616D-1/TR is supplied in reels for SMT-compatible pick-and-place equipment, while the bare part number JANTX1N4616D-1 denotes bulk or ammo-pack formats used in manual or low-volume assembly.
How is the polarity marked on JANTX1N4616D-1/TR?
JANTX1N4616D-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking follows JEDEC DO-35 conventions and is laser-etched or ink-marked per MIL-PRF-19500/435 requirements for permanent legibility after cleaning and conformal coating.
What is the maximum Zener current for JANTX1N4616D-1/TR?
The maximum Zener current (IZM) for JANTX1N4616D-1/TR is 100 mA, derived from its 500 mW power rating and 2.2 V nominal Zener voltage (P = V × I). This value assumes operation at 25 °C lead temperature; actual usable current decreases linearly above 50 °C per the published derating curve in the datasheet.
