Product details
Overview
1N6005UR-1/TR from Microsemi is a surface-mount 16 V, 5% tolerance Zener diode in DO-213AA (SOD-80/MELF) package, rated for 500 mW power dissipation at 25°C, with 36 mA test current (IZT), 600 Ω dynamic impedance (ZZT), and ±0.080%/°C temperature coefficient - used for precision voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the 1N6005UR-1/TR datasheet, 1N6005UR-1/TR pinout, 1N6005UR-1/TR application, or 1N6005UR-1/TR equivalent, this page delivers verified electrical parameters, package dimensions, thermal derating behavior, RoHS compliance status, and direct alternatives for stable supply in industrial control, sensor signal conditioning, and power management designs.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain a stable 16 V across its terminals when biased above its knee current (IZK = 0.25 mA). Its DO-213AA glass MELF construction provides hermetic sealing and radiation hardness per MicroNote 050.
It exhibits minimal junction capacitance (typical <1 pF at VR = 0 V), low leakage (<0.1 µA at VR = 12.8 V), and thermal resistance of 300°C/W junction-to-ambient on FR4 board - enabling reliable operation from –65°C to +175°C with no ESD sensitivity per MIL-STD-750 Method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±5% at IZT = 36 mA - defines nominal regulation point with tight tolerance for stable reference generation. |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power handling before thermal derating applies. |
| Zener Impedance (ZZT) | 600 Ω at IZT = 36 mA - indicates regulation stiffness; lower values yield smaller output voltage variation under load changes. |
| Reverse Leakage (IR) | 0.1 µA max at VR = 12.8 V - ensures minimal quiescent current draw in standby or high-impedance bias networks. |
| Temp Coefficient (αVZ) | +0.080%/°C - quantifies voltage drift with temperature; enables accurate compensation in wide-temperature applications. |
| Max Regulator Current (IZM) | 48 mA - derived from PD/VZM = 0.5 W / 16.8 V ≈ 48 mA; defines absolute safe operating current limit. |
| Junction Temp Range | –65°C to +175°C - supports deployment in harsh environments including automotive under-hood and industrial motor drives. |
Pinout & Package
DO-213AA (SOD-80/MELF) glass hermetically sealed surface-mount package with axial symmetry and cathode band marking. End-cap terminals are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher potential during Zener operation; polarity must be observed to avoid forward conduction. |
| Anode (unbanded end) | Reference/return node | Typically tied to system ground or lower-potential rail; forms return path for Zener current. |
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 option (e3 suffix) | Matte-tin plating meets EU RoHS Directive 2011/65/EU for commercial-grade variants only. |
| Low capacitance (<1 pF typical) | Minimizes high-frequency loading in RF bias networks and fast-switching protection circuits. |
| ESD-insensitive design | No special handling required per MIL-STD-750 Method 1020 - simplifies assembly and field reliability. |
| MIL-PRF-19500 screening available | Qualified equivalents (e.g., JANTXV) support aerospace and defense programs requiring extended reliability testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6005UR-1 | No tape-and-reel packaging; bulk or ammo pack only; identical electrical specs and DO-213AA package. | Suitable for manual prototyping or low-volume hand-soldered assemblies where reel feeding is unnecessary. | Select 1N6005UR-1/TR when automated SMT placement is required; choose 1N6005UR-1 for bench evaluation or small-batch builds. |
| BZX55C16 | DO-35 axial package; same 16 V ±5%, but higher ZZT (120 Ω typical) and lower IZM (42 mA); not RoHS-compliant by default. | Preferred for through-hole prototyping or legacy board upgrades where footprint compatibility matters more than surface-mount density. | Choose BZX55C16 only if DO-35 mechanical fit is mandatory; otherwise, 1N6005UR-1/TR offers superior thermal performance and RoHS compliance. |
Compared with 1N6005UR-1 and BZX55C16, the 1N6005UR-1/TR delivers identical regulation performance in a compact, RoHS-compliant MELF package optimized for automated SMT assembly and high-temperature operation - making it the preferred choice for new industrial and automotive designs requiring traceable sourcing and long-term availability.

FAQ
What is the Zener voltage tolerance of the 1N6005UR-1/TR?
The 1N6005UR-1/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 IZT = 36 mA and 30°C lead temperature. This tolerance is defined by the "B" suffix in the part nomenclature and is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0228-1 Rev. 1.
Is the 1N6005UR-1/TR RoHS compliant?
Yes, the 1N6005UR-1/TR is RoHS compliant, indicated by the "e3" designation in its full part number (1N6005BUR-1/TR e3 per nomenclature guide). RoHS compliance applies only to commercial-grade versions and is achieved via matte-tin plating on the DO-213AA end caps, meeting EU Directive 2011/65/EU requirements.
What is the maximum Zener current (IZM) for the 1N6005UR-1/TR?
The maximum dc Zener current (IZM) for the 1N6005UR-1/TR is 48 mA. This value is calculated using the formula IZM = P / VZM, where P = 0.5 W and VZM = 16.8 V (upper limit of 16 V ±5%). It represents the absolute upper current limit before exceeding the device's power rating under worst-case voltage conditions.
Does the 1N6005UR-1/TR require special ESD handling?
No, the 1N6005UR-1/TR is non-sensitive to ESD per MIL-STD-750 Method 1020, as stated in the Applications/Benefits section of the datasheet. Its glass MELF construction and metallurgical bonding eliminate the need for ESD-safe packaging or handling procedures during assembly or field use.
What is the thermal resistance of the 1N6005UR-1/TR on an FR4 PCB?
The thermal resistance junction-to-ambient (RθJA) for the 1N6005UR-1/TR is 300°C/W when mounted on a standard FR4 printed circuit board with 1 oz copper and the recommended footprint per the Package Dimensions page. This value assumes natural convection cooling and is critical for calculating junction temperature rise under continuous power dissipation.
