Product details
Overview
1N6019UR/TR from Microsemi is a surface-mount 500 mW Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for 62 V nominal Zener voltage at 2 mA test current, with ±5% tolerance (B suffix), 225 Ω dynamic impedance at IZT, and maximum reverse leakage of 0.1 µA at 47 V. It regulates voltage in precision reference and overvoltage protection circuits across industrial power supplies.
For engineers reviewing the 1N6019UR/TR datasheet, 1N6019UR/TR pinout, 1N6019UR/TR application, or 1N6019UR/TR equivalent, key selection criteria include Zener voltage accuracy, low leakage at derated voltage, thermal resistance (150 °C/W junction-to-end cap), RoHS-compliant matte-tin plating, and compatibility with EIA-481-B 12 mm tape-and-reel handling.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable output voltage under varying load and temperature conditions. Its metallurgically bonded glass construction ensures high reliability and radiation hardness per MicroNote 050, with non-sensitive ESD behavior per MIL-STD-750 Method 1020.
The 1N6019UR/TR exhibits a positive temperature coefficient of +0.097 %/°C and is characterized at 30 °C lead temperature with 2 mA test current. Its Zener impedance is measured using 1 kHz AC signal superimposed at 10% of IZT, per MicroNote 202.
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 |
|---|---|---|---|
| 1N6019UR-1 | No TR suffix; supplied in bulk or ammo pack, not tape-and-reel | Lacks EIA-481-B packaging; unsuitable for automated SMT placement | Select 1N6019UR/TR when requiring reel-fed pick-and-place assembly |
| BZX84-C62 | SOT-23 package (3-pin), 350 mW rating, ±5% tolerance, 100 Ω ZZT | Lower power and smaller footprint; higher thermal resistance (350 °C/W) | Choose BZX84-C62 for space-constrained consumer designs where 0.35 W suffices |
Compared with 1N6019UR/TR, the 1N6019UR-1 lacks tape-and-reel support but shares identical electrical specs and DO-213AA packaging, while BZX84-C62 trades power and thermal performance for miniaturization and volume manufacturability in non-military contexts.

FAQ
What is the Zener voltage tolerance of the 1N6019UR/TR?
The 1N6019UR/TR has a nominal Zener voltage of 62 V with ±5% tolerance (denoted by the "B" suffix in its nomenclature), meaning its actual regulation voltage falls between 58.9 V and 65.1 V when tested at 2 mA under standard conditions per T4-LDS-0228-1 Rev. 1.
Does the 1N6019UR/TR meet RoHS requirements?
Yes, the 1N6019UR/TR is RoHS compliant (e3 suffix), featuring matte-tin end-cap plating. This compliance applies only to commercial-grade versions; military-screened variants use tin-lead plating and are not RoHS compliant.
What is the maximum reverse leakage current specification for the 1N6019UR/TR?
The 1N6019UR/TR specifies a maximum reverse leakage current of 0.1 µA at 47 V (80% of nominal Zener voltage), measured at 30 °C lead temperature. This low leakage supports high-impedance bias networks and battery-powered standby circuits.
Can the 1N6019UR/TR be used in space applications?
Yes - the 1N6019UR/TR is inherently radiation hard per Microsemi MicroNote 050 and qualified to MIL-PRF-19500 screening levels. While the TR suffix denotes commercial packaging, the underlying die and construction are suitable for space-grade use when procured with appropriate reliability screening prefixes (e.g., JANTXV).
What is the thermal resistance of the 1N6019UR/TR, and how does it affect PCB layout?
The 1N6019UR/TR has a junction-to-end-cap thermal resistance (RθJL) of 150 °C/W. To sustain full 0.5 W dissipation, the end-cap must be thermally coupled to copper area per the recommended footprint on page 5 of T4-LDS-0228-1; insufficient copper will cause junction overheating and premature failure.
