Product details
Overview
1N6019UR-1/TR from Microsemi is a surface-mount 62 V, 500 mW Zener diode in DO-213AA (MLL34/SOD80) MELF package with ±5% voltage tolerance, 2.0 mA test current, and 225 Ω dynamic impedance at IZT, used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the 1N6019UR-1/TR datasheet, 1N6019UR-1/TR pinout, 1N6019UR-1/TR application, or 1N6019UR-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 47 V), radiation-hardened construction, and RoHS-compliant matte-tin plating for lead-free assembly.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable 62 V across its terminals under regulated current conditions (IZT = 2.0 mA). Its metallurgically bonded glass construction ensures high reliability and low capacitance (typ. <1 pF).
Designed per MIL-PRF-19500 screening standards (commercial grade), it delivers inherent radiation hardness per MicroNote 050 and ESD immunity per MIL-STD-750 Method 1020, with thermal derating starting at 100 °C end-cap temperature.
Key Specifications

|---|---|
| Zener Voltage VZ | 62 V ±5% at 2.0 mA - defines precise regulation point for feedback networks |
| Power Dissipation | 0.5 W at 25 °C ambient - sets maximum continuous power handling on FR4 board |
| Dynamic Impedance ZZT | 225 Ω at IZT = 2.0 mA - determines regulation stability under load transients |
| Reverse Leakage IR | <0.1 µA at 47 V - ensures minimal error current in high-impedance bias networks |
| Junction Temp Range | –65 to +175 °C - supports operation in extended industrial and aerospace environments |
| Thermal Resistance RθJL | 150 °C/W junction-to-end cap - enables thermal design using end-cap heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6019UR-1 | Same electrical specs but in bulk packaging (no tape/reel); identical DO-213AA package and marking | Requires manual placement or non-automated assembly; no EIA-481-B tape compliance | Select when prototyping or low-volume hand-soldered builds where reel logistics are unnecessary |
| BZX84-C62 | SOT-23 package (3.0 × 1.4 mm), 62 V ±5%, 300 mW rating, higher ZZT (400 Ω), max IZM = 42 mA | Smaller footprint but lower power and poorer regulation stability; not radiation-hardened | Choose for space-constrained consumer designs where radiation tolerance and 0.5 W dissipation are not required |
Compared with 1N6019UR-1/TR, the bulk 1N6019UR-1 offers identical performance without tape/reel convenience, while BZX84-C62 trades power handling and radiation hardness for miniaturization-making the TR variant optimal for automated high-reliability production.

FAQ
What is the Zener voltage tolerance and test current for 1N6019UR-1/TR?
The 1N6019UR-1/TR has a nominal Zener voltage of 62 V with ±5% tolerance, measured at a test current (IZT) of 2.0 mA. This tolerance and test condition are specified in the Electrical Characteristics table on page 3 of the T4-LDS-0228-1 datasheet, ensuring predictable regulation behavior in feedback circuits using the 1N6019UR-1/TR.
Is 1N6019UR-1/TR RoHS compliant?
Yes, the 1N6019UR-1/TR is RoHS compliant, featuring matte-tin end-cap plating per the "e3" suffix designation. RoHS compliance applies only to commercial-grade versions; military-screened variants (e.g., MQ1N6019BUR-1) retain tin-lead plating unless otherwise specified. The 1N6019UR-1/TR meets EU Directive 2011/65/EU requirements.
What is the maximum reverse leakage current for 1N6019UR-1/TR?
The maximum reverse leakage current (IR) for the 1N6019UR-1/TR is 0.1 µA at 47 V, as stated in the Electrical Characteristics table. This ultra-low leakage ensures minimal error current in high-impedance voltage divider networks and preserves accuracy in precision regulation applications using the 1N6019UR-1/TR.
Can 1N6019UR-1/TR be used in high-temperature environments?
Yes, the 1N6019UR-1/TR operates across a junction temperature range of –65 to +175 °C and features a thermal resistance of 150 °C/W (junction-to-end cap). When mounted per recommended footprint on FR4, it sustains full 0.5 W dissipation below 100 °C end-cap temperature-making it suitable for under-hood automotive and downhole industrial use cases with the 1N6019UR-1/TR.
What does the "TR" suffix indicate in 1N6019UR-1/TR?
The "TR" suffix in 1N6019UR-1/TR denotes tape-and-reel packaging per EIA-481-B standard using 12 mm carrier tape. This format enables automated pick-and-place assembly in high-volume manufacturing. The base part 1N6019UR-1 is identical electrically and mechanically but supplied in bulk packaging-confirming that the TR variant is optimized for SMT production of the 1N6019UR-1/TR.
