1N3324A

Single Zener Diodes Overview

The Microchip Technology 1N3324A is a high-power 50 W Zener diode from the 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 maximum reverse current of 10 µA. It operates within a junction temperature range of -65°C to +175°C and utilizes a DO-5 (DO-203AB) package.

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

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix required, as the base number denotes a +/-20% tolerance while 'B' indicates +/-5%. Confirm polarity requirements, noting that standard units have an anode-to-case connection and reversed polarity requires an 'R' suffix. Ensure mounting hardware matches the 11/16 inch hexagonal stud specifications.

Single Zener Diodes Selection Notes

Select this component for applications demanding high power dissipation capabilities up to 50 watts. Consider the thermal resistance of 2.0°C/W maximum when designing heat sinking solutions. Evaluate the operating temperature range against environmental conditions and verify compatibility with the DO-5 package dimensions for mechanical integration.

Single Zener Diodes Part Context

This part belongs to the 1N3305 through 1N3350B series of 50 W Zener diodes manufactured by Microsemi Scottsdale Division. The series covers a broad voltage range from 3.9 V to 200 V. These devices are JEDEC registered and also available in JAN, JANTX, and JANTXV military qualifications per MIL-PRF-19500/358.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 50 W Zener diodes with a 30 V rating and DO-5 package. Verify thermal resistance and power derating curves match application requirements before substitution.
