Single Zener Diodes datasheet and documents for 1N3339B

1N3339B

Single Zener Diodes Overview

The Microchip Technology 1N3339B is a high-power 50 W Zener diode from the JEDEC registered 1N3305 through 1N3350B series. It provides voltage regulation with a nominal Zener voltage of 82 V at a test current of 150 mA. The device features a maximum dynamic impedance of 11 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 with a hexagonal stud for mounting.

Single Zener Diodes Feature Summary

Hermetically sealed welded metal and glass construction
Internal solder bond design
Standard polarity connects anode to case
Inherently radiation hard

Single Zener Diodes Applications

High power voltage regulation
Industrial control systems
Power supply protection circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements, as standard units feature anode-to-case polarity while reversed polarity requires an 'R' designation. Confirm thermal management needs, as the 50 W rating depends on maintaining the case temperature below 75°C. Ensure compatibility with the DO-5 hexagonal stud mounting hardware for proper installation.

Single Zener Diodes Selection Notes

Select this component for applications requiring robust voltage reference capabilities in harsh environments. The hermetic seal and radiation hardness make it suitable for military or aerospace contexts. Consider the thermal resistance characteristics when designing heat sinking solutions to maintain performance within the specified operating temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N3305 through 1N3350B series of 50 W Zener diodes manufactured by Microsemi's Scottsdale Division. These devices are designed for broad voltage regulation ranges from 3.9 V to 200 V. The series offers various tolerance options, with the 'B' suffix indicating a standard 5% voltage tolerance.
