Product details
Overview
JAN1N4616D-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 voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4616D-1/TR datasheet, JAN1N4616D-1/TR pinout, JAN1N4616D-1/TR application, or JAN1N4616D-1/TR equivalent, key selection factors include its 1% Zener voltage tolerance, 250 mA test current, 1300 Ω dynamic impedance at IZT, low noise density (1 µV/√Hz), and hermetic DO-35 axial-leaded packaging for stable operation across -65 °C to +175 °C.
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 maximum reverse leakage of 2.0 µA at 1.0 V. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for high-reliability mil-spec applications, it delivers 500 mW average power dissipation with linear derating above 50 °C lead temperature and features minimal junction capacitance (typical <2 pF at 0 V) and ESD immunity per MIL-STD-750 method 1020.

FAQ
What is the Zener voltage tolerance of JAN1N4616D-1/TR?
JAN1N4616D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This means its nominal 2.2 V Zener voltage is guaranteed between 2.178 V and 2.222 V at 250 mA test current and 25 °C ambient, supporting high-accuracy reference design without post-production calibration.
Is JAN1N4616D-1/TR suitable for space applications?
Yes, JAN1N4616D-1/TR is qualified to JANS level per MIL-PRF-19500/435 and exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. Its hermetic DO-35 package and metallurgical bond construction make JAN1N4616D-1/TR appropriate for low-earth orbit and deep-space missions where TID resistance and parameter stability under proton irradiation are essential.
What is the maximum power dissipation for JAN1N4616D-1/TR at 100 °C lead temperature?
Per the linear derating curve in the datasheet, JAN1N4616D-1/TR's 500 mW rated power begins derating at 50 °C lead temperature and reaches zero at 175 °C. At 100 °C lead temperature, its maximum allowable power dissipation is 250 mW - calculated as 500 mW × (1 − (100 − 50)/125) = 250 mW - ensuring safe thermal operation without heatsinking.
Does JAN1N4616D-1/TR have RoHS compliance?
No, JAN1N4616D-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4616D-1e3); JAN-level parts like JAN1N4616D-1/TR retain traditional tin-lead plating per MIL-STD-750 method 2026 to meet solderability and reliability requirements for high-reliability military and aerospace assemblies.
What is the noise performance of JAN1N4616D-1/TR at its Zener test current?
JAN1N4616D-1/TR delivers a maximum noise density of 1 µV/√Hz at 250 mA Zener test current, measured in the 1–3 kHz band. This ultra-low noise characteristic makes JAN1N4616D-1/TR especially valuable in precision analog signal chains, such as sensor excitation, DAC reference buffering, and low-phase-noise oscillator bias networks where broadband noise directly impacts system resolution.
