Product details
Overview
1N6000UR/TR from Microsemi is a surface-mount 10 V, 5% tolerance Zener diode in DO-213AA (SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 7.0 mA test current, 600 Ω dynamic impedance at IZT, and ±0.065%/°C temperature coefficient - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6000UR/TR datasheet, 1N6000UR/TR pinout, 1N6000UR/TR application, or 1N6000UR/TR equivalent, this page delivers verified electrical parameters, package dimensions, thermal derating behavior, RoHS-compliant plating details, and direct alternatives for stable voltage reference design under industrial temperature extremes.
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 hermetic sealing and radiation hardness per MicroNote 050.
It exhibits minimal capacitance (typical <1 pF at 0 V), low leakage (<0.1 µA at 7.6 V), and stable regulation across -65°C to +175°C junction temperature range - validated under MIL-PRF-19500 screening levels when ordered with MQ/MX/MV/CDS prefixes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 10 V at 5.0 mA test current - defines primary regulation point for feedback networks |
| Zener Tolerance | ±5% (B-suffix) - ensures output voltage stays within 9.5–10.5 V at IZT |
| Power Dissipation | 0.5 W at 25°C ambient - limits continuous DC current to ≤50 mA at 10 V without heatsinking |
| Dynamic Impedance | 600 Ω at IZT - determines regulation error under load transients (e.g., ±60 mV change per ±10 mA current shift) |
| Temp. Coefficient | +0.065%/°C - predicts +6.5 mV/°C drift above 25°C, critical for high-stability references |
| Reverse Leakage | ≤0.1 µA at 7.6 V - negligible error contribution in high-impedance bias networks |
| Junction Temp. Range | -65°C to +175°C - supports operation in aerospace, downhole, and military environments |
Pinout & Package
DO-213AA (SOD80 or MLL34) MELF glass package: hermetically sealed cylindrical body with tin-lead or RoHS-compliant matte-tin end-cap plating; cathode identified by single black band; weight 0.04 g; tape-and-reel packaging per EIA-481-B with 12 mm carrier tape (TR suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher-potential side of circuit; reverse-biased to maintain stable 10 V drop |
| Anode (unbanded end) | Reference ground node | Typically tied to system ground or error amplifier inverter input; carries full Zener current |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables operation up to +175°C junction temperature without seal degradation or parameter drift |
| Metallurgical bonding | Eliminates wire bonds and interfacial delamination risks in thermal cycling applications |
| Radiation hardness | Inherently resistant to total ionizing dose (TID) per Microsemi MicroNote 050 - suitable for space-grade designs |
| Low capacitance | Typical <1 pF at 0 V - preserves high-frequency stability in switching regulator feedback paths |
| ESD insensitivity | Non-sensitive per MIL-STD-750 Method 1020 - simplifies handling and eliminates need for ESD protection circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6000UR-1 | No TR suffix - bulk pack, not tape-and-reel; identical electrical specs and DO-213AA package | Not suitable for automated SMT placement; requires manual loading or tube-to-tape conversion | Select 1N6000UR/TR for production lines using pick-and-place machines; choose 1N6000UR-1 only for prototyping or low-volume hand assembly |
| BZX55C10 | DO-35 axial package; same 10 V ±5%, but higher ZZT (150 Ω), lower PD (500 mW same), no MIL-PRF-19500 screening path | Limited to commercial-grade PCBs with through-hole mounting; unsuitable for high-reliability or high-temp environments | Choose BZX55C10 only for cost-sensitive consumer designs where MELF ruggedness and radiation tolerance are unnecessary |
Compared with 1N6000UR/TR, the 1N6000UR-1 offers identical performance but lacks tape-and-reel logistics support, while BZX55C10 trades mechanical robustness and extended temperature capability for lower cost and axial footprint compatibility.

FAQ
What is the Zener voltage tolerance of the 1N6000UR/TR?
The 1N6000UR/TR has a nominal Zener voltage of 10 V with ±5% tolerance (B-suffix), meaning its actual regulation voltage falls between 9.5 V and 10.5 V when tested at 5.0 mA. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0228-1 Rev. 1, and applies across the full operating temperature range.
Does the 1N6000UR/TR support RoHS compliance?
Yes, the 1N6000UR/TR is RoHS compliant (e3 marking), with matte-tin end-cap plating per MIL-STD-750 Method 2026. RoHS compliance is limited to commercial-grade versions only - military-screened variants (MQ/MX/MV/CDS prefixes) retain tin-lead plating and are not RoHS compliant.
What is the maximum continuous Zener current for the 1N6000UR/TR at 25°C?
The maximum continuous Zener current for the 1N6000UR/TR at 25°C is 50 mA, calculated from its 0.5 W power rating and 10 V nominal Zener voltage (IZM = PD/VZ). This value assumes no thermal derating and is validated in the Maximum Ratings table on page 1 of the datasheet.
Is the 1N6000UR/TR suitable for high-temperature environments?
Yes, the 1N6000UR/TR supports junction temperatures from -65°C to +175°C and is qualified for operation in high-temperature industrial and aerospace systems. Its hermetic glass DO-213AA package and metallurgical bonding prevent parameter drift or seal failure under sustained thermal stress.
How does the temperature coefficient affect regulation accuracy of the 1N6000UR/TR?
The 1N6000UR/TR has a temperature coefficient of +0.065%/°C, meaning its Zener voltage increases by approximately +6.5 mV per °C rise above 25°C. At +125°C, this results in a +0.65 V shift - critical for high-accuracy references, requiring compensation or selection of tighter-tolerance units in wide-temperature applications.
