Product details
Overview
1N6020UR-1/TR from Microsemi is a surface-mount 500 mW Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for 68 V nominal Zener voltage at 2.0 mA test current, with ±5% tolerance (B suffix), 240 Ω dynamic impedance at IZT, and -65°C to +175°C junction temperature range. It regulates voltage in precision reference and overvoltage protection circuits across industrial power supplies.
For engineers reviewing the 1N6020UR-1/TR datasheet, 1N6020UR-1/TR pinout, 1N6020UR-1/TR application, or 1N6020UR-1/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (150°C/W junction-to-end cap), low leakage (<0.1 µA at 52 V), radiation-hardened construction, and RoHS-compliant matte-tin plating for commercial-grade reflow compatibility.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with regulation defined at IZT = 2.0 mA and VZ = 68 V. Its metallurgically bonded glass package ensures hermetic sealing and high-reliability performance under thermal cycling and mechanical stress.
The 1N6020UR-1/TR exhibits a positive temperature coefficient of +0.097%/°C and maintains stable regulation across -65°C to +175°C, supported by low capacitance (7.4 pF typical) and minimal ESD sensitivity per MIL-STD-750 Method 1020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6020UR-1 | Same electrical specs but in bulk (non-tape-and-reel) packaging; no TR suffix | Lacks EIA-481-B tape-and-reel compliance; unsuitable for automated SMT placement | Select 1N6020UR-1/TR when using pick-and-place equipment; choose 1N6020UR-1 for hand-soldered prototyping |
| BZX84-C68LT1G | 68 V, ±5%, SOT-23 package; 350 mW rating; 100 Ω ZZT; higher leakage (1 µA @ 54.4 V) | Smaller footprint but lower power and thermal performance; not radiation-hardened | Choose BZX84-C68LT1G only for cost-sensitive consumer designs where radiation tolerance and 0.5 W dissipation are unnecessary |
Compared with 1N6020UR-1/TR, the 1N6020UR-1 lacks tape-and-reel support for production lines, while the BZX84-C68LT1G trades radiation hardness and thermal robustness for compact size and lower unit cost in non-critical environments.

FAQ
What is the Zener voltage tolerance for 1N6020UR-1/TR?
The 1N6020UR-1/TR has a nominal Zener voltage of 68 V with ±5% tolerance, indicated by the "B" suffix in its part nomenclature. This means the actual measured VZ falls between 64.6 V and 71.4 V when tested at 2.0 mA, supporting precision regulation in feedback and reference circuits where moderate accuracy is required.
Does 1N6020UR-1/TR support lead-free reflow soldering?
Yes, the 1N6020UR-1/TR is available in RoHS-compliant versions with matte-tin plating, qualified for lead-free reflow profiles up to 260°C for 10 seconds. The device meets MIL-STD-750 Method 2026 for solderability and maintains parameter stability post-reflow, making it suitable for modern SMT assembly lines.
What is the maximum reverse leakage current specification for 1N6020UR-1/TR?
The 1N6020UR-1/TR specifies a maximum reverse leakage current of 0.1 µA at 52 V (80% of nominal VZ). This ultra-low leakage ensures minimal current draw in high-impedance reference paths, preserving accuracy in precision analog circuits such as multimeter front-ends and sensor bias networks.
Can 1N6020UR-1/TR be used in radiation-intensive environments?
Yes, the 1N6020UR-1/TR is inherently radiation-hardened per Microsemi MicroNote 050, with demonstrated functionality after total ionizing dose (TID) exposure exceeding 100 krad(Si). Its hermetically sealed glass DO-213AA package and metallurgical bonding make it suitable for satellite power systems and nuclear instrumentation.
What does the "TR" suffix signify in 1N6020UR-1/TR?
The "TR" suffix in 1N6020UR-1/TR indicates tape-and-reel packaging per EIA-481-B standard with 12 mm carrier tape, enabling automated surface-mount placement. This distinguishes it from the bulk-packaged 1N6020UR-1 and confirms compatibility with high-volume SMT manufacturing processes.
