1N3324B

Single Zener Diodes Overview

The Microchip Technology 1N3324B is a high-power 50 W Zener diode belonging to the JEDEC registered 1N3305 through 1N3350B series. It provides voltage regulation with a nominal Zener voltage of 30 V at a test current of 420 mA. The device features a maximum dynamic impedance of 3.00 ohms and a typical temperature coefficient of +0.085 %/°C. It operates within a junction and storage temperature range of -65°C to +175°C, dissipating up to 50 watts at a case temperature below 75°C.

Single Zener Diodes Feature Summary

• Hermetically sealed welded metal and glass construction for durability
• Internal solder bond design ensuring robust electrical connections
• Standard polarity configuration with anode connected to the case
• Inherently radiation hard characteristics suitable for harsh environments

Single Zener Diodes Applications

• High power voltage regulation circuits
• Military and aerospace electronic systems
• Industrial equipment requiring rugged components
• Power supply protection and reference applications

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required tolerance suffix (B indicates +/- 5%). Confirm polarity requirements, as standard units have the anode to the case; reverse polarity requires an 'R' suffix. Ensure mounting hardware accommodates the DO-5 hexagonal stud package and verify thermal management capabilities for 50 W dissipation.

Single Zener Diodes Selection Notes

Select this component when high power handling and radiation hardness are critical. The 1N3324B offers a 30 V regulation point with tight tolerance. Consider the DO-5 package size for mechanical integration. Evaluate thermal resistance requirements, noting the maximum junction-to-base thermal resistance is 2.0 °C/W. Verify if military screening levels like JAN or JANTXV are necessary for the application environment.

Single Zener Diodes Part Context

This device is part of the Microsemi Scottsdale Division's 50 Watt Zener Diode family, which includes the 1N3305 through 1N3350B and 1N4549B through 1N4556B series. These components are designed for broad voltage regulation needs ranging from 3.9 V to 200 V. The series is known for low thermal resistance and high reliability in demanding conditions.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 50 W Zener diodes with a 30 V nominal rating and compatible DO-5 packages. Check for matching thermal resistance and tolerance specifications. Military equivalents may require JAN or JANTX prefixes depending on screening requirements.
