Product details
Overview
1N6014UR/TR from Microsemi is a surface-mount 39 V, 5% tolerance Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 2.0 mA test current, 130 Ω dynamic impedance at IZT, and −0.095%/°C temperature coefficient - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6014UR/TR datasheet, 1N6014UR/TR pinout, 1N6014UR/TR application, or 1N6014UR/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (300°C/W junction-to-ambient), low leakage (<0.1 µA at 31.2 V), stable tempco, and RoHS-compliant matte-tin plating on commercial-grade end caps.
Technical Context
This device operates as a reverse-biased voltage reference, maintaining regulation across 0.25 mA to 130 mA dc current range with minimal capacitance (typical <13 pF). Its metallurgically bonded glass construction ensures high reliability and radiation hardness per MicroNote 050.
The DO-213AA package enables automated placement and reflow compatibility, with cathode polarity indicated by a single band and solderable end caps meeting MIL-STD-750 Method 2026. Thermal derating begins at 25°C ambient or 100°C end cap temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 39 V at 2.0 mA test current - defines regulation setpoint for feedback networks |
| Zener Tolerance | ±5% - ensures output voltage stays within 37.05–40.95 V under nominal conditions |
| Power Dissipation | 0.5 W at 25°C ambient - limits maximum continuous power without heatsinking |
| Dynamic Impedance | 130 Ω at IZT - determines output voltage variation under load transients |
| Tempco (αVZ) | −0.095 %/°C - quantifies drift direction and magnitude over temperature |
| Reverse Leakage | <0.1 µA at 31.2 V - guarantees minimal error current in high-impedance references |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C39 | 39 V, ±5%, SOT-23 package, 300 mW rating, higher ZZT (150 Ω), +0.08%/°C tempco | Suitable for low-power portable electronics; not rated for >125°C ambient or radiation environments | Select when board space is constrained and full 500 mW dissipation is unnecessary |

FAQ
What is the Zener voltage tolerance and test current for the 1N6014UR/TR?
The 1N6014UR/TR has a nominal Zener voltage of 39 V with ±5% tolerance, measured at a test current (IZT) of 2.0 mA. This tolerance ensures the actual regulation voltage falls between 37.05 V and 40.95 V under standard test conditions, supporting accurate feedback design in power converters and reference circuits.
Does the 1N6014UR/TR meet RoHS requirements?
Yes, the 1N6014UR/TR is RoHS compliant (e3 suffix), with matte-tin plating on its end caps. This applies only to the commercial-grade version; military-screened variants (e.g., JANTXV) retain tin-lead plating per MIL-PRF-19500 requirements.
What is the maximum reverse leakage current specification for the 1N6014UR/TR?
The 1N6014UR/TR specifies a maximum reverse leakage current of 0.1 µA at 31.2 V (80% of nominal Zener voltage). This low leakage ensures minimal error current in high-impedance reference divider networks and precision analog circuits.
Can the 1N6014UR/TR be used in high-temperature environments?
Yes, the 1N6014UR/TR supports junction temperatures from −65°C to +175°C and is qualified for operation in extended industrial and aerospace environments. Its DO-213AA package and metallurgical construction maintain parameter stability across this full range when mounted per recommended FR4 footprint.
What does the "TR" suffix indicate in the 1N6014UR/TR part number?
"TR" denotes tape-and-reel packaging per EIA-481-B standard using 12 mm carrier tape - optimized for automated SMT placement. The base part 1N6014UR is identical electrically and mechanically; only packaging differs.
