Product details
Overview
JAN1N4133D-1/TR from Microsemi is a 500 mW, 87 V, ±1% tolerance 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 JAN1N4133D-1/TR datasheet, JAN1N4133D-1/TR pinout, JAN1N4133D-1/TR application, or JAN1N4133D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, and hermetic DO-35 packaging for extreme-environment stability.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 87 V at 250 mA test current, exhibiting a temperature coefficient of +0.100 %/°C and dynamic impedance of 1000 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and mechanical stress.
Rated for junction temperatures from –65 °C to +175 °C, it delivers 500 mW average power dissipation with linear derating above 50 °C lead temperature and features minimal capacitance (<1.5 pF typical) and non-ESD-sensitive operation per MIL-STD-750 Method 1020.

FAQ
What is the Zener voltage tolerance of JAN1N4133D-1/TR?
JAN1N4133D-1/TR has a Zener voltage tolerance of ±1%, as indicated by the "D" suffix in its nomenclature. This tight tolerance ensures highly accurate voltage regulation at 87 V under specified test conditions (250 mA, 25 °C), making it suitable for precision reference applications in defense and space systems where standard ±5% parts would introduce unacceptable error margins.
Is JAN1N4133D-1/TR qualified to JANS level?
Yes, JAN1N4133D-1/TR is fully qualified to JANS level per MIL-PRF-19500/435. This highest reliability grade includes rigorous screening for radiation hardness, thermal cycling, mechanical shock, and long-term parametric stability-confirming its suitability for spaceflight and nuclear environments where failure is not an option.
What is the maximum Zener current IZM for JAN1N4133D-1/TR?
The maximum Zener current IZM for JAN1N4133D-1/TR is 40 mA, derived from its 500 mW power rating and 87 V nominal Zener voltage (IZM = 500 mW / 87 V ≈ 40 mA). This value reflects safe continuous operation at 25 °C ambient; derating applies above 50 °C lead temperature per the published power curve.
Does JAN1N4133D-1/TR have low noise performance?
Yes, JAN1N4133D-1/TR exhibits a noise density of 1 µV/√Hz at 250 mA test current, among the lowest in its voltage class. This ultra-low noise characteristic is confirmed in Microsemi's T4-LDS-0245-2 datasheet and enables use in high-fidelity analog measurement systems where reference noise directly impacts signal-to-noise ratio.
What does the "TR" suffix indicate in JAN1N4133D-1/TR?
The "TR" suffix in JAN1N4133D-1/TR denotes tape-and-reel packaging per EIA-296 standard, enabling automated surface-mount or axial insertion assembly. This format supports high-volume production while maintaining full traceability and MIL-qualified handling-critical for defense contractors managing controlled inventory and lot-controlled builds.
