Product details
Overview
JANS1N4616D-1/TR from Microsemi is a 2.2 V, 1% tolerance, 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 voltage regulation. It delivers stable reference voltage at 250 mA test current with 1300 Ω dynamic impedance and -0.075 %/°C temperature coefficient.
For engineers reviewing the JANS1N4616D-1/TR datasheet, JANS1N4616D-1/TR pinout, JANS1N4616D-1/TR application, or JANS1N4616D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), radiation hardness, hermetic glass packaging, noise density (1 µV/√Hz), and MIL-qualified 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 low noise (1 µV/√Hz at 2.2 V) and inherent radiation hardness per Microsemi MicroNote 050.
It exhibits a negative temperature coefficient (-0.075 %/°C), enabling predictable drift compensation in temperature-stable references. Rated for 500 mW average power dissipation at 25 °C, it linearly derates to zero at 175 °C junction temperature per MIL-PRF-19500/435 requirements.

FAQ
What is the Zener voltage and tolerance of JANS1N4616D-1/TR?
JANS1N4616D-1/TR has a nominal Zener voltage of 2.2 V with ±1% tolerance at 250 mA test current, as specified in the Microsemi T4-LDS-0245-2 datasheet. This tight tolerance is achieved through process-controlled metallurgical bonding and is validated per MIL-PRF-19500/435 JANS screening. The 1% tolerance directly reduces calibration overhead in precision analog systems using JANS1N4616D-1/TR.
Is JANS1N4616D-1/TR radiation hardened?
Yes, JANS1N4616D-1/TR is inherently radiation hard per Microsemi MicroNote 050 due to its metallurgically bonded glass construction and DO-35 hermetic package. It is qualified to JANS level per MIL-PRF-19500/435, which includes radiation testing protocols for total ionizing dose (TID). This makes JANS1N4616D-1/TR suitable for space and nuclear environments without additional shielding or derating.
What is the maximum operating temperature for JANS1N4616D-1/TR?
JANS1N4616D-1/TR has a junction and storage temperature range of -65 to +175 °C, per MIL-PRF-19500/435 specifications. Its power dissipation linearly derates from 500 mW at 25 °C to zero at 175 °C. This extended range enables use in engine-mounted avionics, downhole tools, and orbital spacecraft thermal environments where JANS1N4616D-1/TR maintains regulation stability.
Does JANS1N4616D-1/TR have low noise performance?
Yes, JANS1N4616D-1/TR delivers 1 µV/√Hz noise density at 250 mA test current and 2.2 V Zener voltage, as measured per the noise density circuit in Figure 1 of the datasheet. This ultra-low noise is enabled by metallurgical bond construction and is critical for JANS1N4616D-1/TR use in precision instrumentation, sensor front-ends, and calibration references where signal integrity is paramount.
What does the "TR" suffix mean in JANS1N4616D-1/TR?
The "TR" suffix in JANS1N4616D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and supports consistent feeding in high-reliability manufacturing lines. JANS1N4616D-1/TR retains full JANS qualification and electrical specs regardless of packaging format, ensuring traceability and performance consistency across all JANS1N4616D-1/TR deliveries.
