Product details
Overview
1N6013UR/TR from Microsemi is a surface-mount 36 V, 5% tolerance Zener diode in DO-213AA (SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 95 Ω dynamic impedance at 5 mA test current and 0.1 µA reverse leakage at 27 V, used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6013UR/TR datasheet, 1N6013UR/TR pinout, 1N6013UR/TR application, or 1N6013UR/TR equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (300°C/W junction-to-ambient), low capacitance (~14 pF), RoHS-compliant matte-tin plating, and MIL-PRF-19500 screening availability for high-reliability designs.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with Zener voltage specified at 36 V ±5% under 5 mA test current (IZT). Its DO-213AA glass MELF package enables hermetic sealing and high reliability, supporting operation from –65°C to +175°C junction temperature.
Dynamic impedance (ZZT = 95 Ω) and temperature coefficient (+0.094%/°C) are measured per JEDEC standards at 30°C lead temperature. Reverse leakage remains ≤0.1 µA at VR = 27 V, and forward voltage is ≤1.1 V at 200 mA - confirming robust bidirectional handling in protection and clamping roles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±5% at 5 mA - defines stable regulation point for feedback networks requiring tight voltage reference accuracy. |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power handling on FR4 board with 1 oz Cu; derates linearly above 25°C. |
| Dynamic Impedance (ZZT) | 95 Ω at IZT = 5 mA - determines output voltage stability under load transients; lower value improves regulation fidelity. |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 27 V - ensures minimal quiescent current draw in standby or low-power monitoring circuits. |
| Junction Temperature Range | –65°C to +175°C - enables deployment in aerospace, industrial control, and downhole electronics without thermal derating concerns. |
| Capacitance | ~14 pF (typical) - supports high-frequency noise suppression and fast transient response in switching regulator references. |
| Thermal Resistance (RθJA) | 300°C/W - informs PCB copper area requirements; requires ≥100 mm² 1 oz Cu pad for full 0.5 W rating. |
Pinout & Package
DO-213AA (SOD80 or MLL34) glass MELF package: cylindrical hermetically sealed body with tin-lead or RoHS-compliant matte-tin end-cap plating; cathode indicated by single black band; polarity: banded end is cathode (positive during Zener operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common or feedback divider low-side; establishes return path for Zener current. |
| Cathode (banded end) | Regulated output node | Provides stable 36 V reference when reverse-biased; connects to error amplifier input or feedback divider high-side. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables operation up to +175°C junction temperature and inherent radiation hardness per MicroNote 050. |
| RoHS-compliant matte-tin plating | Supports lead-free reflow soldering at 260°C for 10 s without degradation; qualified per MIL-STD-750 Method 2026. |
| Low 14 pF capacitance | Minimizes phase shift in high-frequency feedback paths, preserving stability in DC/DC converter error amplifiers. |
| MIL-PRF-19500 screening option | Available with MQ/MX/MV/CDS prefixes for space-grade, military, or high-reliability applications requiring lot traceability and extended testing. |
| ESD insensitivity | Withstands >4 kV HBM per MIL-STD-750 Method 1020 - eliminates need for external ESD protection in board-level assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C36 | Same 36 V ±5%, but DO-35 axial package; higher RθJA (500°C/W); no MIL screening option. | Limited to commercial PCB layouts with axial footprint; unsuitable for high-density SMT or high-reliability programs. | Select BZX55-C36 only for cost-sensitive prototyping where board space and reliability are secondary. |
| MMBZ5227B | SOT-23 package; same 36 V ±5%; lower PD (350 mW); higher ZZT (150 Ω); RoHS-only. | Lower power handling limits use in >10 mA regulation; SOT-23 thermal performance restricts ambient operation to <85°C. | Choose MMBZ5227B only for space-constrained consumer designs where 0.35 W rating suffices and MIL screening is unnecessary. |
Compared with BZX55-C36 and MMBZ5227B, the 1N6013UR/TR delivers superior thermal performance (300°C/W), hermetic reliability, and military screening readiness - making it the preferred choice for industrial, aerospace, and high-temperature embedded systems requiring long-term voltage reference stability.

FAQ
What is the Zener voltage tolerance of the 1N6013UR/TR?
The 1N6013UR/TR has a nominal Zener voltage of 36 V with a ±5% tolerance, meaning its actual breakdown voltage falls between 34.2 V and 37.8 V when tested at 5 mA (IZT) and 30°C lead temperature. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0228-1 datasheet.
Is the 1N6013UR/TR RoHS compliant?
Yes, the 1N6013UR/TR is RoHS compliant, using matte-tin end-cap plating as specified in the "Part Nomenclature" section of the datasheet. RoHS compliance applies only to commercial-grade versions; military-screened variants (e.g., MQ/ MX prefixes) retain tin-lead plating unless otherwise ordered.
What is the maximum reverse leakage current for the 1N6013UR/TR?
The maximum reverse leakage current (IR) for the 1N6013UR/TR is 0.1 µA at VR = 27 V, as stated in the Electrical Characteristics table. This low leakage ensures minimal power loss in high-impedance reference circuits and supports accurate voltage sensing in battery-powered systems.
Can the 1N6013UR/TR be used in high-temperature environments?
Yes, the 1N6013UR/TR is rated for junction and storage temperatures from –65°C to +175°C. Its hermetic DO-213AA glass package and internal metallurgical bonds enable reliable operation in under-hood automotive, downhole oil/gas, and aerospace applications without derating below 175°C.
Does the 1N6013UR/TR have a defined forward voltage specification?
Yes, the 1N6013UR/TR has a maximum forward voltage (VF) of 1.1 V at 200 mA, per the Maximum Ratings table. This parameter validates its suitability for bidirectional roles such as ESD clamping or reverse-polarity protection, where low forward conduction loss is critical.
