Product details
Overview
1N6025UR/TR from Microsemi is a surface-mount 110 V, 500 mW Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for ±5% voltage tolerance at 1 mA test current, with 650 Ω dynamic impedance and +0.110 %/°C temperature coefficient-used for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the 1N6025UR/TR datasheet, 1N6025UR/TR pinout, 1N6025UR/TR application, or 1N6025UR/TR equivalent, this page delivers verified electrical specs, thermal derating behavior, RoHS-compliant plating details, and direct alternatives for high-reliability industrial and aerospace designs requiring stable 110 V regulation under wide temperature ranges.
Technical Context
This Zener operates in reverse breakdown with cathode-banded polarity, optimized for stable regulation at IZT = 1 mA. Its glass-encapsulated DO-213AA package provides hermetic sealing and low parasitic capacitance (<1 pF typical), supporting noise-sensitive analog references.
Thermal resistance is specified as RθJA = 300 °C/W on FR4 (1 oz Cu), with full power dissipation only up to TA = 25 °C and linear derating above-critical for compact PCB layouts where end-cap conduction dominates heat transfer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 110 V ±5% at IZT = 1 mA - defines nominal regulation point with tight tolerance for feedback accuracy |
| Power Dissipation PD | 0.5 W at TA ≤ 25 °C - sets maximum continuous power before thermal shutdown or drift |
| Dynamic Impedance ZZT | 650 Ω at 1 kHz, 10% IZT - determines AC ripple rejection capability in regulated supplies |
| Temp. Coefficient αVZ | +0.110 %/°C - quantifies voltage drift per degree; positive sign indicates rising VZ with temperature |
| Reverse Leakage IR | 0.1 µA at VR = 84 V - ensures minimal standby current in high-impedance bias networks |
| Junction Temp. Range | –65 to +175 °C - enables operation in extended industrial and aerospace environments |
| Forward Voltage VF | 1.1 V at 200 mA - relevant for ESD testing and forward-conduction fault analysis |
Pinout & Package
DO-213AA (SOD80/MLL34) MELF glass package: cylindrical, metallurgically bonded, hermetically sealed, with tin-lead or RoHS-compliant matte-tin end-cap plating. Cathode identified by single black band; no discrete pins-end caps serve as anode and cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode End Cap (banded) | Zener regulation terminal | Connected to higher potential during regulation; defines polarity for correct biasing in shunt configuration |
| Anode End Cap (unbanded) | Reference/ground terminal | Typically tied to system ground or lower-potential node; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Eliminates moisture ingress and long-term parameter drift-critical for mission-critical timing and reference circuits |
| RoHS-compliant plating (e3) | Matte-tin end caps meet lead-free assembly requirements without compromising solderability or intermetallic reliability |
| MIL-PRF-19500 screening option | Enables qualification for defense/aerospace programs via prefix-modified part numbers (e.g., MQ1N6025BUR) |
| Low capacitance & ESD robustness | Sub-1 pF junction capacitance minimizes high-frequency loading; non-sensitive to ESD per MIL-STD-750 Method 1020 |
| Radiation-hardened design | Inherently tolerant to total ionizing dose (TID), validated per Microsemi MicroNote 050 for space-grade applications |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6025B-TR | Same 110 V, ±5%, DO-213AA package but axial DO-35 (1N6025B-1) variant-no tape-and-reel suffix; non-RoHS plating | Preferred for through-hole prototyping or legacy board rework where surface-mount footprint is unavailable | Select 1N6025B-TR only if RoHS exemption applies and axial mounting is required; otherwise prefer 1N6025UR/TR for SMT production |
| BZX85C110-TAP | 110 V, ±5%, DO-41 package; 1.3 W rating; higher ZZT = 900 Ω; no MIL-PRF-19500 screening path | Suitable for higher-power bench supplies but lacks radiation hardness and hermetic sealing | Choose BZX85C110-TAP only when >0.5 W dissipation is needed and space allows larger DO-41 footprint |
Compared with 1N6025UR/TR, 1N6025B-TR offers identical regulation but requires manual assembly and lacks RoHS compliance, while BZX85C110-TAP trades hermetic reliability and low capacitance for higher power-neither is pin-compatible due to differing packages and termination styles.

FAQ
What is the Zener voltage tolerance and test current for 1N6025UR/TR?
The 1N6025UR/TR has a nominal Zener voltage of 110 V with ±5% tolerance, measured at a test current IZT of 1 mA. This tolerance ensures predictable regulation performance across manufacturing lots and supports accurate feedback loop design in power converters where 110 V serves as a precise reference threshold.
Is 1N6025UR/TR RoHS compliant and what plating does it use?
Yes, the 1N6025UR/TR is RoHS compliant (e3 suffix), featuring matte-tin plating on both end caps. This plating meets J-STD-006 requirements for lead-free soldering and maintains reliable wetting and intermetallic formation during reflow at 260 °C for 10 seconds-critical for high-yield SMT assembly.
What is the maximum reverse leakage current specification for 1N6025UR/TR?
The 1N6025UR/TR specifies a maximum reverse leakage current IR of 0.1 µA at VR = 84 V. This ultra-low leakage ensures minimal current draw in high-impedance bias networks and preserves accuracy in precision reference applications where even nanoamp-level errors affect system gain or offset calibration.
Can 1N6025UR/TR be used in radiation-intensive environments like space systems?
Yes, the 1N6025UR/TR is inherently radiation-hardened per Microsemi MicroNote 050, with demonstrated tolerance to total ionizing dose (TID) exceeding 100 krad(Si). Its hermetic DO-213AA glass package prevents parametric degradation under proton and gamma irradiation-making it suitable for satellite power conditioning and onboard instrumentation.
What thermal derating applies to 1N6025UR/TR above 25 °C ambient?
1N6025UR/TR must be derated linearly above 25 °C ambient: power dissipation decreases by 1.67 mW/°C (based on RθJA = 300 °C/W), reaching zero at 175 °C. For reliable operation at elevated temperatures, thermal design must prioritize end-cap conduction-using copper pour or thermal vias beneath the MELF body-to maintain junction temperature within –65 to +175 °C limits.
