Product details
Overview
1N4583AUR-1/TR from Microsemi is a hermetically sealed, temperature-compensated Zener reference diode in DO-213AA (MELF) glass package, rated for 4.0 mA test current, ±0.001 %/°C temperature coefficient, and 10 mV voltage stability over −55°C to +100°C. It serves as a precision voltage reference in aerospace-grade power monitoring and analog sensor signal conditioning circuits.
For engineers reviewing the 1N4583AUR-1/TR datasheet, 1N4583AUR-1/TR pinout, 1N4583AUR-1/TR application, or 1N4583AUR-1/TR equivalent, key selection criteria include low dynamic impedance (25 Ω), tight tempco, MIL-PRF-19500/452 JANTXV qualification, and operation within 0.5–4.0 mA range under harsh thermal cycling.
Technical Context
This device belongs to Microsemi's CDLL45xxA series of metallurgically bonded, double-plug Zener diodes engineered for ultra-stable voltage references in high-reliability systems. Its construction minimizes thermal hysteresis and long-term drift, with effective voltage stability specified at ±10 mV across −55°C to +100°C per JEDEC 5.
The 1N4583AUR-1/TR operates at 4.0 mA test current with 25 Ω dynamic impedance and exhibits a temperature coefficient of ±0.001 %/°C - among the lowest in its family - enabling sub-ppm/°C reference performance when biased precisely.

FAQ
What is the Zener test current for the 1N4583AUR-1/TR?
The 1N4583AUR-1/TR is characterized at a Zener test current (IZT) of 4.0 mA. This current level is required to achieve the specified voltage stability of ±10 mV and dynamic impedance of 25 Ω. Operating significantly below or above this point increases tempco error and impedance deviation, so bias networks must be designed to maintain ~4.0 mA under all operating conditions for full specification compliance.
Is the 1N4583AUR-1/TR qualified to MIL-PRF-19500/452?
Yes, the 1N4583AUR-1/TR is qualified to MIL-PRF-19500/452 as a JANTXV-level device. It undergoes full military screening including temperature cycling, hermeticity testing, burn-in, and long-term life testing. The "AUR" suffix denotes hermetic MELF packaging, and "TR" indicates tape-and-reel delivery - both consistent with MIL-PRF-19500/452 mechanical and packaging requirements for high-reliability Zener references.
What does the "A" suffix mean in 1N4583AUR-1/TR?
The "A" in 1N4583AUR-1/TR denotes the enhanced temperature range version: −55°C to +100°C voltage stability (vs. 0°C to +75°C for non-A variants). It also reflects tighter tempco (±0.001 %/°C) and higher dynamic impedance tolerance (10 Ω vs. 5 Ω for some lower-tempco grades). This "A" grade is mandatory for applications exposed to wide thermal excursions, such as spacecraft thermal vacuum cycling or jet engine-mounted electronics.
Can the 1N4583AUR-1/TR replace CDLL4583A in existing designs?
Yes, the 1N4583AUR-1/TR is a direct form-fit-function replacement for CDLL4583A: same DO-213AA package, identical electrical specs (4.0 mA IZT, ±0.001 %/°C tempco, 10 mV stability), and shared MIL-PRF-19500/452 JANTXV qualification. No PCB layout or schematic changes are needed; only procurement channel and reel labeling differ. Both parts share the same Microsemi die and assembly process.
What is the maximum operating temperature for the 1N4583AUR-1/TR?
The 1N4583AUR-1/TR has a maximum operating temperature of +175°C and a storage temperature range of −65°C to +175°C. This rating is enabled by its hermetic DO-213AA glass package and metallurgically bonded construction. While voltage stability is guaranteed only over −55°C to +100°C per spec, the device remains functional and non-destructive up to +175°C - making it suitable for downhole, turbine, and propulsion-system environments where transient thermal extremes occur.
