Overview
JANS1N4616-1/TR from Microsemi is a 2.2 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers 2.2 V regulation at 250 mA test current, with 1% voltage tolerance, 1300 Ω dynamic impedance, and -0.075 %/°C temperature coefficient.
For engineers reviewing the JANS1N4616-1/TR datasheet, JANS1N4616-1/TR pinout, JANS1N4616-1/TR application, or JANS1N4616-1/TR equivalent, key selection criteria include Zener voltage accuracy, low noise density (1 µV/√Hz), radiation hardness, hermetic DO-35 packaging, and military-grade reliability qualification.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures stable regulation across wide current (250 mA IZT) and temperature (-65 °C to +175 °C) ranges.
It exhibits low noise density (1 µV/√Hz), minimal capacitance (typical <2 pF), and inherent radiation hardness per Microsemi MicroNote 050 - characteristics critical for analog signal conditioning and power supply feedback in harsh environments.

FAQ
What is the Zener voltage and test current for JANS1N4616-1/TR?
JANS1N4616-1/TR has a nominal Zener voltage of 2.2 V measured at a test current (IZT) of 250 mA. This value is guaranteed within ±1% tolerance and specified at 25 °C ambient temperature with the device in thermal equilibrium. The 250 mA IZT reflects its optimized regulation point for low dynamic impedance and stable voltage output.
Is JANS1N4616-1/TR radiation hardened?
Yes, JANS1N4616-1/TR is inherently radiation hard per Microsemi MicroNote 050. Its metallurgically bonded glass construction and JANS-level qualification per MIL-PRF-19500/435 confirm suitability for total ionizing dose (TID) environments typical in space and nuclear applications - no additional shielding or derating is required for standard mission profiles.
What does the "TR" suffix mean in JANS1N4616-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANS1N4616-1/TR retains full JANS qualification and electrical specifications; only the packaging format differs from bulk or ammo-pack versions. Reel quantities and orientation follow factory-standard configurations for high-reliability handling.
What is the maximum operating temperature for JANS1N4616-1/TR?
JANS1N4616-1/TR has a junction and storage temperature range of -65 °C to +175 °C. Its power dissipation must be linearly derated from 500 mW starting at 50 °C lead temperature, reaching zero at 175 °C. On a typical FR4 board, derating begins at 25 °C ambient, ensuring safe operation across extended military and aerospace thermal profiles.
How does the noise performance of JANS1N4616-1/TR compare to higher-voltage Zeners in the same series?
JANS1N4616-1/TR delivers 1 µV/√Hz noise density at 250 mA - the lowest in the 1N4614–1N4627 family. Noise rises with Zener voltage: 6.8 V+ devices reach 40 µV/√Hz. This makes JANS1N4616-1/TR optimal for ultra-low-noise analog references where sub-millivolt RMS noise is critical to system resolution.
