Product details
Overview
1N6001UR/TR from Microsemi is a surface-mount 11 V, 500 mW Zener diode in DO-213AA (SOD-80/MELF) package with ±5% voltage tolerance, 600 Ω dynamic impedance at 5 mA test current, and -65°C to +175°C junction temperature range; used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6001UR/TR datasheet, 1N6001UR/TR pinout, 1N6001UR/TR application, or 1N6001UR/TR equivalent, this page delivers verified electrical specs, thermal derating behavior, RoHS-compliant commercial-grade packaging, 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 8.4 V) and inherent radiation hardness per MicroNote 050.
Thermal resistance is specified as 150°C/W junction-to-end-cap and 300°C/W junction-to-ambient on FR4 with 1 oz Cu, enabling reliable operation up to 175°C junction temperature when mounted per recommended footprint. Dynamic impedance (ZZT = 600 Ω) is measured at 1 kHz with 10% rms AC current superimposed on 5 mA DC test current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V ±5% at 5 mA test current - defines nominal regulation point with tight tolerance for stable reference generation. |
| Power Dissipation | 0.5 W at 25°C ambient - sets maximum continuous power handling before thermal derating applies. |
| Dynamic Impedance (ZZT) | 600 Ω at IZT = 5 mA - determines output voltage variation under load transients; lower values improve regulation accuracy. |
| Reverse Leakage Current | <0.1 µA at 8.4 V - ensures minimal error current in high-impedance reference paths. |
| Junction Temperature Range | -65°C to +175°C - supports operation in extended industrial and aerospace environments without derating penalties. |
| Forward Voltage | 1.1 V at 200 mA - defines conduction threshold in forward bias; relevant for ESD protection or dual-use circuit analysis. |
Pinout & Package
DO-213AA (SOD-80 / MELF) hermetically sealed glass package with tin-lead or RoHS-compliant matte-tin end-cap plating; cathode identified by single black band; weight 0.04 g; tape-and-reel delivery per EIA-481-B with 12 mm carrier tape.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener regulation terminal | Must be biased positive relative to anode to enter breakdown; serves as regulated output node in shunt regulator topologies. |
| Anode (unbanded end) | Reference return terminal | Connected to system ground or low-side reference point; completes current path during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables stable long-term Zener voltage drift & immunity to moisture-induced parameter shift in harsh environments. |
| RoHS-compliant commercial grade | Matte-tin end-cap plating meets EU RoHS Directive 2011/65/EU without lead content; suitable for green manufacturing. |
| Low capacitance profile | Typical <1 pF at 0 V - minimizes high-frequency coupling noise in RF-adjacent or fast-switching power control circuits. |
| Radiation-hardened design | Inherent tolerance to total ionizing dose (TID) per Microsemi MicroNote 050 - validated for space-qualified applications. |
Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Reference Voltage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6001UR-1 | Same electrical specs but axial DO-35 (DO204AH) package; no tape-and-reel option; non-RoHS default plating. | Preferred for through-hole prototyping or legacy board rework where SMT footprint unavailable. | Select 1N6001UR-1 only when manual assembly or compatibility with existing DO-35 footprints is required. |
| BZX55C11 | 5% tolerance, 500 mW, DO-35 package; higher ZZT (700 Ω); not radiation-hardened; RoHS-compliant variants available. | Cost-optimized alternative for commercial-grade consumer electronics where radiation tolerance is unnecessary. | Choose BZX55C11 for cost-sensitive volume production where environmental robustness is secondary to unit price. |
Compared with 1N6001UR/TR, the 1N6001UR-1 offers identical regulation performance in axial form for legacy designs, while BZX55C11 provides lower-cost regulation in non-radiation environments-neither is pin-compatible due to differing packages, requiring layout changes.

FAQ
What is the Zener voltage tolerance and test current for the 1N6001UR/TR?
The 1N6001UR/TR has a nominal Zener voltage of 11 V with ±5% tolerance, measured at a test current (IZT) of 5 mA. This tolerance ensures predictable regulation performance across production lots and supports use in applications requiring moderate precision without active trimming.
Is the 1N6001UR/TR RoHS compliant?
Yes, the 1N6001UR/TR is RoHS compliant with matte-tin end-cap plating, as confirmed in the T4-LDS-0228-1 datasheet. RoHS compliance applies only to commercial-grade versions; military-screened variants (e.g., JANTXV) retain tin-lead plating unless otherwise specified.
What is the maximum reverse leakage current for the 1N6001UR/TR?
The 1N6001UR/TR exhibits a maximum reverse leakage current of 0.1 µA at 8.4 V (90% of VZ). This ultra-low leakage preserves accuracy in high-impedance reference circuits and minimizes error contributions in precision analog signal chains.
Can the 1N6001UR/TR be used in high-temperature environments?
Yes, the 1N6001UR/TR supports junction temperatures from -65°C to +175°C and is rated for continuous operation at full 0.5 W power dissipation below 100°C end-cap temperature. Its glass-MELF construction ensures stability under thermal cycling stress.
What package type does the 1N6001UR/TR use?
The 1N6001UR/TR uses the DO-213AA (SOD-80 / MELF) surface-mount glass package, featuring hermetically sealed construction, cathode band marking, and compatibility with standard 12 mm tape-and-reel handling per EIA-481-B.
