1N3038B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3038B-1/TR is a 56 V Zener diode with a 5% voltage tolerance, housed in a DO-41 glass package. It operates within a temperature range of -55°C to +175°C and dissipates up to 1 W. Key electrical parameters include a test current of 4.5 mA, maximum reverse leakage of 10 µA, dynamic impedance of 110 Ω at the test point, and a forward voltage of 1.2 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range.
• Features a hermetically sealed glass case for high-reliability applications.
• Offers low reverse leakage currents and inherent radiation hardness.
