Product details
Overview
1N6031UR-1/TR from Microsemi is a surface-mount 200 V, ±5% tolerance Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 0.1 µA reverse leakage at 152 V, used for precision voltage regulation in industrial power supplies and overvoltage protection circuits.
For engineers reviewing the 1N6031UR-1/TR datasheet, 1N6031UR-1/TR pinout, 1N6031UR-1/TR application, or 1N6031UR-1/TR equivalent, key selection criteria include Zener voltage tolerance (±5%), dynamic impedance (2700 Ω @ IZT), thermal resistance (300 °C/W), and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with nominal Zener voltage of 200 V at 1.0 mA test current (IZT) and specified knee current (IZK) of 0.25 mA. Its temperature coefficient is +0.110 %/°C, indicating stable high-voltage regulation across industrial temperature ranges.
The DO-213AA glass MELF package provides hermetic sealing, low capacitance (typical 2.5 pF), and radiation hardness per MicroNote 050. It uses metallurgically bonded end caps and complies with MIL-STD-750 method 2026 for solderability.
Key Specifications

| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power handling on FR4 board |
| Dynamic Impedance (ZZT) | 2700 Ω @ IZT = 1.0 mA - indicates regulation stiffness under small-signal AC modulation |
| Reverse Leakage (IR) | 0.1 µA @ 152 V - ensures minimal standby current in high-impedance bias networks |
| Junction Temperature Range | –65 to +175°C - supports operation in extended industrial and aerospace environments |
| Thermal Resistance (RθJA) | 300°C/W - determines required PCB copper area for thermal management |
| Forward Voltage (VF) | 1.1 V @ 200 mA - defines conduction loss when used in forward-biased clamp configurations |
Pinout & Package
DO-213AA (SOD80 / MLL34) glass MELF package: hermetically sealed cylindrical body with tin-lead or RoHS-compliant matte-tin plated end caps; cathode indicated by single band; polarity requires banded end to be positive during Zener operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener regulation terminal | Connected to higher potential node; reverse-biased to maintain regulated voltage drop |
| Anode (unbanded end) | Reference/return terminal | Connected to circuit ground or lower-potential rail; completes Zener current path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6031B-1 | Axial DO-35 package; identical electrical specs but through-hole mounting | Requires wave soldering or hand assembly; unsuitable for high-density SMT layouts | Select when legacy board repair or mixed-technology assembly is required |
| BZX85C200 | 500 mW, 200 V ±5%, DO-41 package; higher RθJA (500°C/W) and 5 µA leakage at 152 V | Lower reliability in high-temp environments; not radiation-hardened | Choose only for cost-sensitive commercial designs where radiation tolerance is unnecessary |
Compared with 1N6031UR-1/TR, the 1N6031B-1 offers identical regulation performance but demands PCB through-holes and manual rework capability, while BZX85C200 trades radiation hardness and leakage performance for broader distributor availability at lower unit cost.

FAQ
What is the Zener voltage tolerance for 1N6031UR-1/TR?
The 1N6031UR-1/TR has a ±5% Zener voltage tolerance, denoted by the "B" suffix in its nomenclature. This means its actual breakdown voltage falls between 190 V and 210 V when measured at the specified 1.0 mA test current (IZT) and 30°C lead temperature, as confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0228-1 Rev. 1.
Is 1N6031UR-1/TR RoHS compliant?
Yes, the 1N6031UR-1/TR is RoHS compliant, indicated by the "e3" marking per Microsemi's part nomenclature guide. The device uses matte-tin plating on its end caps and meets EU Directive 2011/65/EU requirements, though this compliance applies only to commercial-grade versions-not military-screened variants.
What package type does 1N6031UR-1/TR use?
The 1N6031UR-1/TR uses the DO-213AA package, also known as SOD80 or MLL34, a glass-encapsulated MELF (Metal Electrode Leadless Face) surface-mount package. Its dimensions are 1.60–1.70 mm diameter and 3.30–3.70 mm length, with metallurgically bonded end caps for high reliability.
What is the maximum reverse leakage current for 1N6031UR-1/TR?
The maximum reverse leakage current for 1N6031UR-1/TR is 0.1 µA at 152 V, as specified in the Electrical Characteristics table. This value is measured at 30°C lead temperature and reflects the device's ability to maintain high-impedance blocking behavior well below its 200 V Zener voltage.
Can 1N6031UR-1/TR be used in high-temperature environments?
Yes, the 1N6031UR-1/TR is rated for junction and storage temperatures from –65°C to +175°C. Its thermal resistance junction-to-ambient is 300°C/W when mounted on an FR4 board with 1 oz copper, enabling reliable operation in extended industrial and aerospace applications when proper PCB thermal design is implemented.
