Product details
Overview
1N6002UR/TR from Microsemi is a surface-mount 12 V Zener diode in DO-213AA (SOD-80) MELF package, rated for 500 mW power dissipation at 25°C, with ±5% voltage tolerance, 5 mA test current, and 750 Ω dynamic impedance at IZT. It regulates voltage across industrial power supplies and precision reference circuits.
For engineers reviewing the 1N6002UR/TR datasheet, 1N6002UR/TR pinout, 1N6002UR/TR application, or 1N6002UR/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (300 °C/W), low leakage (<0.1 µA at 9.1 V), RoHS-compliant matte-tin plating, and MIL-PRF-19500 screening compatibility.
Technical Context
This device operates as a two-terminal voltage reference by maintaining stable reverse breakdown at 12 V under regulated current conditions (IZT = 5 mA). Its glass-encapsulated DO-213AA construction provides hermetic sealing and radiation hardness per MicroNote 050.
It exhibits a positive temperature coefficient of +0.073 %/°C and minimal junction capacitance (typ. 33 pF), enabling stable regulation over –65 to +175 °C junction temperature range without external compensation.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 12 V ±5% at 5 mA - defines nominal regulation point with tight tolerance for reference stability |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power handling on FR4 board |
| Dynamic Impedance (ZZT) | 750 Ω at 5 mA - indicates voltage regulation sensitivity to current variation |
| Reverse Leakage (IR) | <0.1 µA at 9.1 V - ensures minimal parasitic current in high-impedance bias networks |
| Junction Temperature Range | –65 to +175 °C - supports operation in extended industrial and aerospace environments |
| Thermal Resistance (RθJA) | 300 °C/W - determines required PCB copper area for thermal management |
| Forward Voltage (VF) | 1.1 V at 200 mA - relevant for polarity verification and ESD-safe forward-bias testing |
Pinout & Package
DO-213AA (SOD-80/MELF) glass package with axial symmetry and cathode band marking; terminals are metallurgically bonded end caps with matte-tin (RoHS) or tin-lead plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher potential during Zener operation; band identifies polarity for correct orientation |
| Anode (unbanded end) | Reference ground node | Connected to lower potential; forms return path for Zener current in shunt regulator topology |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6002UR-1 | Tape-and-reel packaging omitted; same electrical specs and DO-213AA package | Manual placement or low-volume prototyping where reel feeding is unnecessary | Select 1N6002UR/TR for automated SMT assembly; choose 1N6002UR-1 for hand-soldered evaluation |
| BZX55C12 | DO-35 axial package; 5% tolerance; 500 mW rating; higher RθJA (~500 °C/W) | Through-hole designs requiring legacy footprint compatibility and lower thermal performance margin | Choose BZX55C12 only when board layout prohibits MELF geometry or requires axial leaded form factor |
Compared with 1N6002UR/TR, the 1N6002UR-1 offers identical regulation performance but lacks tape-and-reel support for pick-and-place, while BZX55C12 trades superior thermal resistance and surface-mount compatibility for through-hole assembly flexibility.

FAQ
What is the Zener voltage tolerance for 1N6002UR/TR?
The 1N6002UR/TR has a nominal Zener voltage of 12 V with a ±5% tolerance, meaning its actual breakdown voltage falls between 11.4 V and 12.6 V when tested at 5 mA. This tolerance is indicated by the "B" suffix in the part nomenclature and applies across the full operating temperature range of –65 to +175 °C.
Is 1N6002UR/TR RoHS compliant?
Yes, the 1N6002UR/TR is RoHS compliant (e3 designation), featuring matte-tin plating on its DO-213AA end caps. RoHS compliance applies only to commercial-grade versions; military-screened variants (e.g., MQ/ MX-prefixed) retain tin-lead plating per MIL-STD-750.
What does the "TR" suffix mean in 1N6002UR/TR?
The "TR" suffix denotes tape-and-reel packaging per EIA-481-B standard using 12 mm carrier tape, enabling automated surface-mount assembly. This distinguishes it from the bulk or ammo-pack versions (e.g., 1N6002UR-1) and confirms compatibility with standard SMT pick-and-place equipment.
Can 1N6002UR/TR replace older 1N6002B diodes?
Yes, the 1N6002UR/TR is a direct functional replacement for the legacy 1N6002B, retaining identical Zener voltage (12 V), tolerance (±5%), power rating (0.5 W), and DO-213AA package. The "UR" designation confirms surface-mount equivalence to JEDEC 1N6002B with updated packaging and RoHS compliance.
What is the maximum reverse leakage current for 1N6002UR/TR?
The maximum reverse leakage current for 1N6002UR/TR is 0.1 µA at 9.1 V (85% of nominal Zener voltage), measured at 30 °C lead temperature. This ultra-low leakage ensures minimal error in high-impedance reference networks and supports stable operation in battery-powered sensor nodes.
