1N3336RB

Single Zener Diodes Overview

The Microchip Technology 1N3336RB is a high-power 50 W Zener diode from the 1N3305-1N3350B 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 Ohms and a maximum reverse current of 10 µA. It utilizes a DO-5 (DO-203AB) package with an 11/16 inch hexagonal stud. The 'R' suffix indicates reversed polarity, connecting the cathode to the case.

Single Zener Diodes Feature Summary

• Hermetically sealed welded metal and glass construction for durability
• Internal solder bond design ensuring robust electrical connections
• Reversed polarity configuration with cathode connected to the case
• Inherently radiation hard per Microsemi MicroNote 050

Single Zener Diodes Applications

• High power voltage regulation in industrial systems
• Overvoltage protection circuits requiring robust thermal management
• Military and aerospace applications utilizing JAN/JANTX qualifications

Single Zener Diodes Procurement Notes

Verify the specific revision level and manufacturing origin when sourcing this component. Confirm that the required military screening levels (JAN, JANTX, or JANTXV) are explicitly stated in the purchase order if applicable. Ensure mounting hardware specifications align with the 11/16 inch hexagonal stud dimensions provided in the datasheet.

Single Zener Diodes Selection Notes

Select this component for applications requiring high power dissipation up to 50 watts. Ensure adequate heat sinking is available as power must be derated above 75°C case temperature. Verify that the reversed polarity orientation matches the circuit design requirements, as the standard version connects the anode to the case.

Single Zener Diodes Part Context

This part belongs to the 1N3305 through 1N3350B series of 50 Watt Zener diodes manufactured by Microchip Technology's Scottsdale Division. These devices are designed for broad voltage ranges from 3.9 V to 200 V. The series includes variants with different tolerance suffixes and polarity options to suit various high-power regulation needs.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N3335B and 1N3337B. For reversed polarity versions, check 1N3335RB and 1N3337RB. Military qualified equivalents are available with JAN, JANTX, or JANTXV prefixes.
