Product details
Overview
1N6023UR-1/TR from Microsemi is a surface-mount 500 mW Zener diode with nominal Zener voltage of 91 V, ±5% tolerance (B suffix), 2.0 mA test current, and dynamic impedance of 300 Ω at IZT. It operates in the breakdown region for precision voltage regulation in power supply feedback loops and overvoltage protection circuits across industrial and aerospace systems.
For engineers reviewing the 1N6023UR-1/TR datasheet, 1N6023UR-1/TR pinout, 1N6023UR-1/TR application, or 1N6023UR-1/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJA = 300 °C/W), low leakage (<0.1 µA at 73 V), radiation-hardened construction, and DO-213AA MELF package compatibility with automated SMT assembly.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse-biased Zener breakdown mode. Its regulation performance is defined at 2.0 mA test current (IZT) with 300 Ω dynamic impedance (ZZT) and temperature coefficient of +0.099 %/°C - indicating stable high-voltage reference behavior above 75 V.
The 1N6023UR-1/TR uses hermetically sealed glass DO-213AA (SOD80/MLL34) packaging with metallurgically bonded end caps, enabling operation from −65 °C to +175 °C and compliance with MIL-PRF-19500 screening when ordered with appropriate prefixes. It exhibits minimal capacitance and inherent radiation hardness per MicroNote 050.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6023UR-1 | Same electrical specs but in bulk (non-tape-and-reel) packaging; no TR suffix | Limited to manual or non-automated assembly; lacks EIA-481-B tape alignment features | Select 1N6023UR-1/TR when using pick-and-place machines requiring 12 mm carrier tape. |
| BZX85C91 | 91 V ±5%, 1.3 W power rating, DO-41 axial package, higher RθJA (~500 °C/W) | Suitable for prototyping or through-hole boards; not compatible with SMT production lines | Choose BZX85C91 only for breadboarding or legacy through-hole designs where board real estate permits axial leads. |
Compared with 1N6023UR-1/TR, the bulk 1N6023UR-1 lacks tape-and-reel logistics for SMT, while BZX85C91 trades surface-mount compatibility for higher power and through-hole mounting - making 1N6023UR-1/TR optimal for high-reliability, automated production of compact high-voltage regulators.

FAQ
What is the Zener voltage tolerance of the 1N6023UR-1/TR?
The 1N6023UR-1/TR has a nominal Zener voltage of 91 V with ±5% tolerance, indicated by the "B" suffix in its part number per Microsemi's nomenclature. This means the actual measured VZ falls between 86.45 V and 95.55 V when tested at 2.0 mA, supporting tight regulation in feedback and reference applications.
Does the 1N6023UR-1/TR meet RoHS requirements?
Yes, the 1N6023UR-1/TR is RoHS compliant (e3 designation), featuring matte-tin end-cap plating suitable for lead-free reflow soldering per MIL-STD-750, method 2026. RoHS compliance applies only to commercial-grade versions; military-screened variants may differ in plating specification.
What is the maximum reverse leakage current for the 1N6023UR-1/TR?
The 1N6023UR-1/TR specifies a maximum reverse leakage current of 0.1 µA at 73 V (80% of nominal 91 V), measured at 30 °C lead temperature. This ultra-low leakage ensures minimal error current in high-impedance reference circuits such as precision voltage dividers or op-amp bias networks.
Can the 1N6023UR-1/TR be used in high-temperature environments?
Yes, the 1N6023UR-1/TR is rated for junction and storage temperatures from −65 °C to +175 °C. Its DO-213AA glass package and metallurgical bonding enable reliable operation in under-hood automotive, downhole oil/gas, and avionics applications where extreme thermal cycling occurs.
What does the "TR" suffix indicate in 1N6023UR-1/TR?
The "TR" suffix denotes tape-and-reel packaging per EIA-481-B standard with 12 mm carrier tape, optimized for automated SMT placement. This distinguishes 1N6023UR-1/TR from the bulk-packaged 1N6023UR-1 and ensures consistent feeding, orientation, and traceability in high-volume manufacturing.
