Product details
Overview
1N6000UR-1/TR from Microsemi is a surface-mount 10 V Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for 500 mW power dissipation at 25°C, ±5% voltage tolerance, and 15 mA test current. It provides stable voltage regulation in low-power analog reference and overvoltage protection circuits across industrial temperature ranges.
For engineers reviewing the 1N6000UR-1/TR datasheet, 1N6000UR-1/TR pinout, 1N6000UR-1/TR application, or 1N6000UR-1/TR equivalent, key selection criteria include Zener voltage accuracy, dynamic impedance at 15 mA, thermal resistance (300°C/W junction-to-ambient), RoHS compliance status, and DO-213AA footprint compatibility with automated SMT assembly.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with specified Zener voltage (VZ = 10 V @ IZT = 15 mA), dynamic impedance (ZZT = 600 Ω), and temperature coefficient (+0.065%/°C). Its glass-encapsulated MELF construction ensures hermetic sealing and radiation hardness per MicroNote 050.
Designed for commercial-grade applications, it supports lead-free reflow up to 260°C for 10 seconds and exhibits minimal capacitance (<1.5 pF typical at 0 V), making it suitable for high-frequency biasing and noise-sensitive reference nodes where parasitic coupling must be minimized.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 10 V at 15 mA test current - defines nominal regulation point under standard bias conditions |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous DC power before thermal derating applies |
| Zener Impedance (ZZT) | 600 Ω at 15 mA - determines output voltage variation under load current changes |
| Reverse Leakage (IR) | 0.1 µA at 7.6 V - ensures negligible current draw below knee voltage in standby operation |

| Package Type | DO-213AA (MLL34/SOD80) - cylindrical MELF glass body with end-cap terminations for high-reliability SMT mounting |
Pinout & Package
DO-213AA (SOD80/MLL34) is a hermetically sealed glass MELF package with two metallized end caps serving as anode and cathode terminals. Polarity is marked by a single cathode band; the banded end is positive during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher-potential rail; reverse-biased to maintain fixed 10 V drop relative to anode |

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 | Same electrical specs but in bulk packaging (no tape-and-reel); identical DO-213AA package and marking | Not suitable for high-speed automated pick-and-place; requires manual or tube-based placement | Select 1N6000UR-1/TR when SMT line throughput and reel logistics are required |
| BZX55C10 | 5% tolerance, 500 mW, DO-35 axial package; ZZT = 20 Ω @ 5 mA - lower impedance but different test current and package | Requires through-hole assembly and larger board area; unsuitable for dense SMT layouts | Choose BZX55C10 only if legacy axial design or lower dynamic impedance at low current is critical |
Compared with 1N6000UR-1/TR, the 1N6000UR-1 lacks tape-and-reel support for SMT production, while BZX55C10 offers tighter ZZT but demands axial mounting and different thermal management-making 1N6000UR-1/TR optimal for modern compact SMT voltage references requiring MELF reliability and RoHS compliance.

FAQ
What is the Zener voltage tolerance for 1N6000UR-1/TR?
The 1N6000UR-1/TR has a ±5% Zener voltage tolerance, meaning its regulated voltage falls between 9.5 V and 10.5 V when tested at 15 mA. This tolerance is indicated by the "B" suffix in the part nomenclature and aligns with the 1N5985BUR–1N6031BUR series specification sheet. The 1N6000UR-1/TR maintains this tolerance across its full operating temperature range of –65°C to +175°C.
Does 1N6000UR-1/TR support lead-free reflow soldering?
Yes, the 1N6000UR-1/TR supports lead-free reflow soldering with a maximum peak temperature of 260°C for 10 seconds, as specified in the Microsemi datasheet. Its RoHS-compliant matte-tin end-cap plating ensures reliable wetting and intermetallic formation during standard Pb-free reflow profiles. The 1N6000UR-1/TR is rated for commercial-grade use and does not require special pre-bake or moisture sensitivity handling.
What is the maximum Zener current (IZM) for 1N6000UR-1/TR?
The maximum Zener current IZM for 1N6000UR-1/TR is 8.0 mA at nominal 10 V, calculated per the datasheet formula IZM = PD/VZM, where VZM = 10.5 V (10 V × 1.05 tolerance) and PD = 0.5 W. This value reflects worst-case current under maximum voltage tolerance and full power dissipation. The 1N6000UR-1/TR is characterized at 15 mA test current (IZT) for voltage measurement, but sustained operation above 8.0 mA risks exceeding 0.5 W rating unless derated.
Is 1N6000UR-1/TR suitable for high-frequency applications?
Yes, the 1N6000UR-1/TR is suitable for high-frequency applications due to its typical capacitance of less than 1.5 pF at 0 V, as shown in Figure 2 of the datasheet. Its DO-213AA glass MELF construction minimizes parasitic inductance and provides stable impedance behavior up to several hundred MHz. The 1N6000UR-1/TR is commonly used in RF bias networks and fast transient clamping where low capacitance and predictable breakdown response are essential.
How is polarity marked on 1N6000UR-1/TR?
Polarity on the 1N6000UR-1/TR is marked by a single cathode band located near one end of the cylindrical DO-213AA glass body. During Zener regulation, the banded end must be held at a higher potential than the opposite (unbanded) end. The cathode band corresponds to the positive terminal in reverse-bias operation, and the unbanded end serves as the anode/reference ground connection. This marking is consistent across all 1N5985BUR–1N6031BUR series devices.
