1N3336B

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 68 V at a test current of 180 mA. The device features a maximum dynamic impedance of 8.00 ohms and a maximum reverse current of 10 µA. It operates within a junction and storage temperature range of -65°C to +175°C, with DC power dissipation rated at 50 watts when case temperature is below 75°C.

Single Zener Diodes Feature Summary

• Hermetically sealed welded construction with internal solder bond for reliability
• Inherently radiation hard design suitable for harsh environments
• Low thermal resistance junction-to-hexagonal base for efficient heat dissipation
• Standard polarity configuration with anode connected to the case

Single Zener Diodes Applications

• High power voltage regulation in military systems
• Power supply protection circuits requiring robust thermal performance
• Radiation-hardened electronic assemblies

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the datasheet before ordering. Confirm that the application environment supports the specified thermal operating limits. Ensure mounting hardware matches the DO-5 hexagonal stud dimensions. Check for availability of JAN, JANTX, or JANTXV qualifications if military screening is required. Consult factory documentation for surface mount equivalents if space constraints exist.

Single Zener Diodes Selection Notes

Select this component for applications demanding high power handling and wide temperature stability. The 68 V rating fits within the broad 3.9 V to 200 V regulation range. Consider the 50 W dissipation capability and low thermal resistance for effective heat sinking. Verify tolerance requirements, as the B suffix indicates +/- 5% Zener voltage accuracy. Evaluate the standard anode-to-case polarity against circuit layout needs.

Single Zener Diodes Part Context

This part belongs to the Microsemi Scottsdale Division 1N3305 through 1N3350B series of 50 Watt Zener diodes. These devices are JEDEC registered and offer a wide selection of voltages. The series is also available in military qualifications including JAN, JANTX, and JANTXV per MIL-PRF-19500/358 by adding appropriate prefixes to the part number.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N4554B from the parallel 1N4549B through 1N4556B series. Military screened versions such as JANTX1N3336B or JANTXV1N3336B provide higher screening levels while maintaining identical electrical characteristics.
