1N3336A

Single Zener Diodes Overview

The Microchip Technology 1N3336B 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 75 V at a test current of 170 mA. The device features a maximum dynamic impedance of 9.0 Ohms and a maximum DC Zener current of 540 mA. 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
• Overvoltage protection systems

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements when ordering. The 'B' suffix indicates a standard tolerance of plus or minus 5 percent on the Zener voltage. An 'R' suffix denotes reversed polarity where the cathode connects to the case. Confirm that the application includes adequate mounting hardware and heat sinking to manage the 50 watt power dissipation effectively.

Single Zener Diodes Selection Notes

Select this component for applications requiring high power handling capabilities and strict voltage stability. Ensure the thermal management system maintains the case temperature below 75 degrees Celsius to utilize the full 50 watt rating. Consider the physical dimensions of the DO-5 package and the required hexagonal stud mounting interface during the mechanical design phase.

Single Zener Diodes Part Context

This part belongs to the Microsemi Scottsdale Division series of 50 Watt Zener Diodes. The series covers a broad voltage range from 3.9 V to 200 V. These devices are designed for high reliability and are available in various military qualifications including JAN, JANTX, and JANTXV levels upon request by adding specific prefixes to the part number.

Single Zener Diodes Replacement Considerations
