Product details
Overview
1N6005UR/TR from Microsemi is a surface-mount 16 V, 500 mW Zener diode in DO-213AA (SOD80/MLL34) MELF package with ±5% voltage tolerance, 31 Ω dynamic impedance at 5 mA test current, and -65 °C to +175 °C operating junction temperature - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6005UR/TR datasheet, 1N6005UR/TR pinout, 1N6005UR/TR application, or 1N6005UR/TR equivalent, this page delivers verified electrical specs, thermal derating behavior, RoHS-compliant commercial-grade availability, and direct alternatives for voltage reference design validation.
Technical Context
This Zener operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgically bonded glass construction ensures stable leakage performance (<0.1 µA at 12 V) and minimal capacitance (typ. <3 pF).
The device exhibits a +0.080 %/°C temperature coefficient and is rated for 500 mW dissipation at 25 °C ambient on FR4 with 1 oz Cu, derating linearly to zero at 100 °C end-cap temperature per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±5% at 5 mA test current - defines nominal regulation point with tight tolerance for stable reference generation. |
| Power Dissipation (PD) | 0.5 W at TA ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB without forced cooling. |
| Zener Impedance (ZZT) | 31 Ω at IZT = 5 mA - determines output voltage variation under load transients; lower value improves regulation fidelity. |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 12 V - ensures minimal error current in high-impedance reference paths. |
| Temp. Coefficient (αVZ) | +0.080 %/°C - quantifies drift magnitude over temperature; enables compensation in precision analog designs. |
| Junction Temp. Range | -65 °C to +175 °C - supports operation in extended industrial, aerospace, and downhole environments. |
| Package Type | DO-213AA (SOD80/MLL34) MELF - hermetically sealed glass surface-mount package with end-cap terminations for high reliability. |
Pinout & Package
DO-213AA (SOD80/MLL34) MELF package: hermetically sealed glass cylindrical body with tin-lead or RoHS-compliant matte-tin plated end caps; cathode indicated by single band; polarity critical - banded end is cathode (positive during Zener operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; forms low-impedance return path for Zener current. |
| Cathode (banded end) | Regulated output node | Held at precise 16 V relative to anode; supplies stable bias/reference voltage to downstream circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount DO-213AA package | Enables automated assembly and high-density PCB layouts while maintaining hermetic reliability. |
| Metallurgical bonding | Ensures robust interfacial integrity between silicon die and end caps, minimizing parameter shift under thermal cycling. |
| Non-ESD-sensitive construction | Withstands >4 kV HBM per MIL-STD-750 Method 1020 - eliminates need for ESD protection in handling and assembly. |
| Radiation-hardened structure | Inherently tolerant to total ionizing dose (TID) per MicroNote 050 - suitable for space and nuclear instrumentation. |
| RoHS-compliant option | e3 suffix indicates matte-tin plating - meets EU RoHS Directive 2011/65/EU for commercial-grade versions only. |
Applications
| Power Supply Feedback Loop | Overvoltage Protection Circuit |
|---|---|
Use Scenario: Regulates output voltage in isolated flyback or forward converter feedback networks using optocoupler-coupled TL431 replacement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | 300 mW SOT-23 package; 16 V ±5%; ZZT = 40 Ω at 5 mA; max TJ = +150 °C. | Limited power handling and thermal margin; unsuitable for >100 °C ambient or >300 mW dissipation. | Select when board space is constrained and power demand stays below 300 mW with ambient <85 °C. |
| MMBZ5245B | 350 mW SOT-23; 16 V ±5%; ZZT = 30 Ω at 20 mA; higher test current shifts knee point. | Higher IZT requires larger bias resistor; less stable at low currents typical of reference use. | Prefer for general-purpose clamping where 20 mA bias is acceptable and thermal constraints allow. |
Compared with BZX84-C16 and MMBZ5245B, the 1N6005UR/TR delivers higher power rating (500 mW), wider temperature range (-65 °C to +175 °C), lower ZZT at standard 5 mA test current, and hermetic DO-213AA packaging - making it optimal for high-reliability, high-temperature, and precision reference applications.

FAQ
What is the Zener voltage tolerance of the 1N6005UR/TR?
The 1N6005UR/TR has a nominal Zener voltage of 16 V with a ±5% tolerance, meaning its actual regulation voltage falls between 15.2 V and 16.8 V when tested at 5 mA DC current and 30 °C lead temperature, per Microsemi T4-LDS-0228-1 Rev. 1 specifications.
Is the 1N6005UR/TR RoHS compliant?
Yes, the "e3" suffix in the full part number 1N6005UR/TR indicates RoHS compliance with matte-tin plating on end caps; however, this applies only to commercial-grade units - military-screened variants are not RoHS compliant per Microsemi documentation.
What is the maximum reverse leakage current for the 1N6005UR/TR?
The 1N6005UR/TR exhibits a maximum reverse leakage current (IR) of 0.1 µA at VR = 12 V and 30 °C, as specified in the Electrical Characteristics table on Page 3 of Microsemi's T4-LDS-0228-1 datasheet - critical for low-power reference stability.
Does the 1N6005UR/TR require heatsinking in standard PCB layouts?
No, the 1N6005UR/TR does not require external heatsinking when mounted on FR4 with 1 oz copper per Microsemi's recommended footprint; its thermal resistance junction-to-ambient is 300 °C/W, enabling full 500 mW dissipation up to 25 °C ambient, with linear derating beyond that.
How is polarity marked on the 1N6005UR/TR package?
The 1N6005UR/TR uses a single cathode band on the glass DO-213AA body to indicate polarity - the banded end is the cathode and must be held positive relative to the unbanded (anode) end during Zener regulation, as confirmed in the Mechanical and Packaging section of the datasheet.
