Product details
Overview
JANS1N4575AUR-1/TR from Microsemi is a hermetically sealed, temperature-compensated Zener reference diode in DO-213AA (MELF) glass package, rated for 2.0 mA test current, ±100 mV voltage stability over −55°C to +100°C, and 50 Ω dynamic impedance - used in precision voltage references for aerospace-grade power regulation and analog measurement circuits.
For engineers reviewing the JANS1N4575AUR-1/TR datasheet, JANS1N4575AUR-1/TR pinout, JANS1N4575AUR-1/TR application, or JANS1N4575AUR-1/TR equivalent, key selection criteria include temperature coefficient (±0.01 %/°C), low-current operation (2.0 mA), hermetic MELF packaging, and MIL-PRF-19500/452 JANS qualification for high-reliability environments.
Technical Context
This device belongs to the CDLL4575A family of temperature-compensated Zener diodes, featuring metallurgically bonded double-plug construction to minimize thermal hysteresis and drift. It operates within a low-current range (2.0 mA) and delivers stable reference voltage under wide temperature extremes (−55°C to +100°C).
The ±0.01 %/°C temperature coefficient and ≤100 mV total voltage deviation across temperature are achieved via internal compensation networks. Its 50 Ω zener impedance (ZZT) ensures minimal AC perturbation during precision DC referencing in regulated power supplies and instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | Specified at 2.0 mA test current; enables stable reference generation in low-power analog circuits. |
| Temp. Coefficient | ±0.01 %/°C - ensures minimal drift over −55°C to +100°C for aerospace-grade calibration. |
| Voltage Stability | ≤100 mV max deviation across full temp range - meets MIL-PRF-19500/452 Class A limits. |
| Zener Impedance | 50 Ω - maintains tight regulation under varying load or ripple conditions in precision supplies. |
| Package | DO-213AA (MELF) - hermetically sealed glass case with axial CTE ~+6 ppm/°C for reliable thermal matching. |
| Power Dissipation | 500 mW @ +50°C, derated 4 mW/°C above - supports continuous operation in conduction-cooled modules. |
Pinout & Package
DO-213AA (MELF) glass package: cylindrical, leadless, hermetically sealed surface-mount device with cathode band marking; no discrete pins - terminals defined by axial ends (anode/cathode). Mounting orientation is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode End | Current entry point in forward bias; referenced ground in reverse-biased Zener operation. | Connected to lower-potential node in shunt reference configuration; requires thermal-aware PCB pad design. |
| Cathode End (banded) | Zener breakdown terminal; held at higher potential during regulation. | Marked end must be biased positive relative to anode; polarity reversal causes catastrophic failure. |
Key Features
| Feature | Design Value |
|---|---|
| Temperature Compensation | Double-plug metallurgical construction reduces TC drift to ±0.01 %/°C - critical for unheated avionics references. |
| Hermetic Sealing | DO-213AA glass package prevents moisture ingress and long-term parameter shift - qualified per MIL-STD-750. |
| Low-Current Operation | Optimized for 2.0 mA ZT - enables battery-powered or ultra-low-quiescent systems without sacrificing stability. |
| MIL-Spec Qualification | JANS level per MIL-PRF-19500/452 - includes radiation hardness assurance, lot traceability, and extended life testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4575AUR-1 | Same electrical specs; JANTXV grade - wider screening, tighter lot acceptance testing than JANS. | Used where enhanced reliability screening is mandated but full JANS radiation assurance not required. | Select when system-level radiation tolerance is not specified but extended burn-in and parametric spread control are needed. |
| CDLL4575A | Identical Zener parameters and temperature behavior; non-military commercial version, no MIL-PRF-19500 qualification. | Applicable only in non-aerospace industrial or test equipment where hermeticity and lot traceability are optional. | Choose for cost-sensitive prototyping or ground-based lab instruments with relaxed qualification requirements. |
Compared with JANS1N4575AUR-1/TR, JANTXV1N4575AUR-1 offers stricter screening without electrical change, while CDLL4575A provides identical performance without military qualification - enabling trade-offs between radiation assurance, reliability screening depth, and procurement cost.
