Product details
Overview
JANS1N4580AUR-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, ±100 mV voltage stability over −55°C to +100°C, and 25 Ω dynamic impedance; used in precision voltage references for aerospace-grade power supply regulation and analog measurement circuits.
For engineers reviewing the JANS1N4580AUR-1/TR datasheet, JANS1N4580AUR-1/TR pinout, JANS1N4580AUR-1/TR application, or JANS1N4580AUR-1/TR equivalent, key selection criteria include its MIL-PRF-19500/452 qualification, low TC of ±0.01%/°C, 500 mW power rating at +50°C, and hermetic MELF construction for high-reliability analog reference design.
Technical Context
This device belongs to the CDLL4565–CDLL4584A family of temperature-compensated Zener diodes, employing metallurgically bonded double-plug construction to minimize voltage drift across temperature extremes. It operates within a low-current range (0.5–4.0 mA) and delivers stable reference voltage under JEDEC-standard thermal cycling per Note 1.
Zener impedance is measured with 10% of IZT superimposed as 60 Hz RMS AC current (per Note 2), yielding 25 Ω typical at 4.0 mA. Its axial coefficient of expansion (+6 ppm/°C) requires matched PCB substrate selection to prevent mechanical stress-induced parameter shift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | Specified at 4.0 mA test current; exact value depends on specific variant in CDLL4580A series - critical for precision reference accuracy. |
| Temp. Coefficient | ±0.01 %/°C - enables <100 mV total drift over −55°C to +100°C, meeting tight analog system tolerance budgets. |
| Zener Impedance ZZT | 25 Ω max at IZT = 4.0 mA - ensures minimal AC ripple coupling into reference node during regulation. |
| Power Dissipation | 500 mW @ +50°C, derated 4 mW/°C above - defines maximum continuous DC bias without thermal runaway in sealed enclosures. |
| Operating Temp. | −65°C to +175°C - supports operation in extreme environments including space-grade and downhole electronics. |
| Reverse Leakage | 2 µA @ 25°C, 3 V reverse - confirms low parasitic current that preserves reference node integrity in high-impedance circuits. |
Pinout & Package
Package: DO-213AA (MELF, SOD-80, LL34), hermetically sealed glass case with tin/lead lead finish. Cathode identified by band; operated with banded end positive.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground connection | Low-impedance return path for Zener bias current; must be tied to stable system ground plane. |
| Cathode | Positive reference output | Provides stabilized voltage node; polarity marking (band) must align with positive supply orientation. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4580AUR-1 | Same electrical specs; qualified to JANTXV level (−65°C to +125°C operating, tighter screening) | Preferred for non-space flight hardware requiring extended reliability but not full JANS radiation assurance | Select when radiation hardness is unnecessary but higher screening yield is required |
| CDLL4580A | Commercial-grade version; same VZ, TC, ZZT, but no MIL-spec screening or hermeticity | Suitable for lab-grade instrumentation or industrial controls where cost and availability outweigh environmental robustness | Select for prototyping or non-critical systems with budget constraints |
Compared with JANS1N4580AUR-1/TR, JANTXV1N4580AUR-1 offers enhanced screening without electrical change, while CDLL4580A sacrifices hermeticity and qualification for lower cost-making the JANS variant uniquely suited for mission-critical, radiation-exposed, or extreme-temperature deployments.

FAQ
What is the Zener test current for JANS1N4580AUR-1/TR?
JANS1N4580AUR-1/TR is specified at a Zener test current (IZT) of 4.0 mA. This current level is used to measure nominal Zener voltage, temperature coefficient, and dynamic impedance. Operating significantly above or below this point may increase voltage drift or impedance, affecting reference accuracy in precision circuits.
Is JANS1N4580AUR-1/TR hermetically sealed?
Yes, JANS1N4580AUR-1/TR uses a DO-213AA glass package with hermetic sealing, confirmed by Microsemi's design data and MIL-PRF-19500/452 qualification. This prevents moisture ingress and ensures long-term parametric stability in high-humidity or vacuum environments such as spacecraft and downhole tools.
What does the "JANS" prefix indicate for JANS1N4580AUR-1/TR?
The "JANS" prefix certifies that JANS1N4580AUR-1/TR meets the highest military reliability standard per MIL-PRF-19500/452, including radiation hardness assurance, extended temperature screening (−65°C to +125°C operating), and 100% lot testing. It is approved for use in spaceflight, nuclear, and strategic defense systems.
Can JANS1N4580AUR-1/TR replace CDLL4580A in existing designs?
JANS1N4580AUR-1/TR shares identical electrical specifications with CDLL4580A but adds hermetic packaging and MIL-spec screening. Physical dimensions match (DO-213AA), so board layout is compatible. However, JANS1N4580AUR-1/TR requires adherence to military handling, traceability, and documentation requirements not needed for CDLL4580A.
What is the maximum power dissipation for JANS1N4580AUR-1/TR at +100°C?
At +100°C, JANS1N4580AUR-1/TR has a derated power dissipation of 300 mW. Starting from 500 mW at +50°C and applying the 4 mW/°C derating factor, the allowable dissipation drops linearly - critical for thermal design in sealed enclosures or high-ambient environments like engine bays or downhole tools.
