1N3310B

Overview

The Microchip Technology 1N3310B is a high-power 50 W Zener diode within the JEDEC registered 1N3305 through 1N3350B series. It provides voltage regulation with a nominal Zener voltage of 8.2 V at a test current (IZT) of 1,500 mA. The device features a maximum dynamic impedance (ZZT) of 0.40 Ohms and a maximum DC Zener current (IZM) of 5,200 mA. Packaged in a hermetically sealed DO-5 (DO-203AB) metal and glass case with an 11/16 inch hexagonal stud, it operates from -65°C to +175°C junction temperature.

Feature Summary

Hermetically sealed welded construction for durability
Internal solder bond design
Standard polarity with anode connected to the case
Radiation hard characteristics

Applications

High power voltage regulation
Overvoltage protection circuits
Reference voltage generation

Procurement Notes

Verify the specific part number against the official datasheet to confirm tolerance suffixes and polarity options. Ensure mounting hardware requirements align with the hexagonal stud specifications. Confirm thermal management capabilities meet the 50 W dissipation rating under intended operating conditions. Check for military qualification prefixes if required by the application environment.

Selection Notes

Select this component for applications requiring robust voltage regulation in harsh environments. Consider the DO-5 package size and stud mounting requirements during mechanical design. Evaluate thermal resistance and heat sinking needs to maintain junction temperatures within the specified range. Verify that the 8.2 V nominal voltage matches the system reference requirements.

Part Context

This component belongs to the Microsemi Scottsdale Division 50 Watt Zener Diodes family. It shares the same package and general electrical characteristics as other devices in the 1N3305 through 1N3350B series, differentiated primarily by their specific Zener voltage ratings. The series is designed for high power applications requiring reliable performance over a wide temperature range.

Replacement Considerations

Equivalent parts include other 50 W Zener diodes with similar voltage ratings and DO-5 packages. Verify compatibility with MIL-PRF-19500/358 standards if military qualification is necessary. Ensure replacement devices match the thermal resistance and physical dimensions for direct interchangeability.
