Product details
Overview
1N6029UR-1/TR from Microsemi is a surface-mount 500 mW Zener diode with nominal Zener voltage 160 V, ±5% tolerance (B-suffix), DO-213AA (MLL34/SOD80) MELF glass package, and 1 mA maximum reverse leakage at 122 V. It regulates voltage across industrial power supplies and high-voltage reference circuits.
For engineers reviewing the 1N6029UR-1/TR datasheet, 1N6029UR-1/TR pinout, 1N6029UR-1/TR application, or 1N6029UR-1/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (300 °C/W), junction temperature range (–65 to +175 °C), low capacitance, and RoHS-compliant commercial-grade availability.
Technical Context
This device operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its Zener impedance is 2000 Ω at 1 mA test current (IZT), with dynamic impedance ZZK of 2700 Ω near the knee (IZK = 0.25 mA), confirming regulation stability at low currents.
Designed for precision voltage reference and overvoltage protection, it features hermetically sealed glass construction, metallurgical bonding, and minimal capacitance - critical for noise-sensitive analog and high-frequency power control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 160 V ±5% at 1 mA - defines precise clamping threshold for 122–168 V operating window |
| Power Dissipation (PD) | 0.5 W at 25 °C ambient - limits continuous dissipation without derating on FR4 board |
| Junction Temperature Range | –65 to +175 °C - supports operation in harsh industrial and aerospace environments |
| Reverse Leakage (IR) | 0.1 µA max at 122 V - ensures minimal standby current in high-impedance bias networks |
| Zener Impedance (ZZT) | 2000 Ω at IZT = 1 mA - indicates moderate regulation stiffness for medium-precision references |
| Thermal Resistance (RθJA) | 300 °C/W - requires careful PCB copper area planning to avoid thermal runaway above 25 °C ambient |
| Package | DO-213AA (SOD80/MLL34) MELF - enables automated placement and high-reliability hermetic sealing |
Pinout & Package
DO-213AA (SOD80/MLL34) MELF glass package with axial end-cap terminals. Cathode identified by single black band; operated with banded end positive relative to opposite end during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher-potential rail; sinks current to maintain 160 V reference |
| Anode (unbanded end) | Reference return node | Connected to circuit ground or lower-potential rail; completes Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Hermetically sealed glass construction | Prevents moisture ingress and long-term parameter drift in humid or corrosive environments |
| Metallurgically bonded terminals | Ensures robust mechanical and thermal interface between silicon die and end caps for reliable power cycling |
| RoHS-compliant matte-tin plating | Enables lead-free reflow soldering per JEDEC J-STD-020 while maintaining solderability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6029UR-1 | Same electrical specs, but in bulk (non-tape-and-reel) packaging | Not suitable for automated SMT assembly; requires manual or tray-based placement | Select when prototyping or low-volume hand-soldering is used |
| BZX85C160 | 500 mW, 160 V, ±5%, but in DO-41 axial package (not surface mount) | Requires through-hole PCB layout; incompatible with SMT production flow | Select only if legacy through-hole design or manual repair constraints apply |
Compared with 1N6029UR-1/TR, the 1N6029UR-1 lacks tape-and-reel support for pick-and-place, while BZX85C160 introduces mechanical and assembly incompatibility due to axial DO-41 packaging - making 1N6029UR-1/TR the sole RoHS-compliant, MELF-format, tape-and-reel-ready option for high-reliability SMT 160 V Zener regulation.

FAQ
What is the Zener voltage tolerance for 1N6029UR-1/TR?
The "B" suffix in 1N6029UR-1/TR denotes ±5% Zener voltage tolerance, meaning its actual breakdown voltage falls between 152 V and 168 V when measured at 1 mA test current and 30 °C lead temperature, per Microsemi T4-LDS-0228-1 Rev. 1 specifications.
Is 1N6029UR-1/TR RoHS compliant?
Yes, 1N6029UR-1/TR is RoHS compliant (e3 marking), featuring matte-tin terminal plating suitable for lead-free reflow soldering. This compliance applies only to the commercial-grade version - military-screened variants are not RoHS compliant per Microsemi documentation.
What does the "TR" suffix indicate in 1N6029UR-1/TR?
The "TR" suffix in 1N6029UR-1/TR specifies tape-and-reel packaging per EIA-481-B standard using 12 mm carrier tape, enabling automated SMT placement. This distinguishes it from the bulk-packaged 1N6029UR-1 variant and confirms factory-verified reel quantity and orientation consistency.
What is the maximum reverse leakage current for 1N6029UR-1/TR?
The maximum reverse leakage current for 1N6029UR-1/TR is 0.1 µA at 122 V (80% of nominal 160 V Zener voltage), measured at 30 °C lead temperature. This ultra-low leakage supports high-impedance bias networks and precision reference divider stability.
Can 1N6029UR-1/TR be used in radiation-intensive environments?
Yes, 1N6029UR-1/TR is inherently radiation-hardened per Microsemi MicroNote 050, with documented performance retention after total ionizing dose (TID) exposure up to 100 krad(Si). Its hermetic glass package and silicon process make it suitable for satellite and nuclear instrumentation applications.
