1N3039B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3039B-1/TR is a 62-volt Zener diode with a 5% voltage tolerance, housed in a glass DO-41 package. It operates within a junction temperature range of -55°C to +175°C and dissipates up to 1 watt. Key electrical parameters include a test current (IZT) of 4.0 mA, maximum dynamic impedance (ZZT) of 125 ohms at IZT, and maximum reverse leakage current (IR) of 10 µA. The device features a maximum temperature coefficient of 0.104 %/°C.

Single Zener Diodes Procurement Notes

Verify the specific suffix against official documentation to confirm RoHS compliance status and packaging format. Ensure the ordering code matches the required reliability level (JAN, JANTX, or JANTXV) as commercial versions may differ from qualified levels. Confirm tape and reel specifications if applicable.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 62-volt reference with tight 5% tolerance. Consider the 1-watt power dissipation limit and thermal derating requirements when designing the circuit layout. Verify that the 125-ohm dynamic impedance meets the noise and stability requirements of the target application.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt glass case Zener diodes. The series offers a wide voltage selection from 6.8 to 110 volts in the DO-41 package.
