1N3341A

Single Zener Diodes Overview

The Microchip Technology 1N3341A is a high-power 50 W Zener diode belonging to the JEDEC registered 1N3305 through 1N3350B series. It provides voltage regulation with a nominal Zener voltage of 105 V and a test current (IZT) of 120 mA. The device features a maximum DC Zener current (IZM) of 380 mA and operates within a junction temperature range of -65°C to +175°C. It utilizes a DO-5 (DO-203AB) hexagonal stud package with standard anode-to-case polarity.

Single Zener Diodes Feature Summary

• Hermetically sealed welded metal and glass construction for durability
• Internal solder bond design ensuring robust electrical connections
• Inherently radiation hard characteristics suitable for harsh environments
• Low thermal resistance junction-to-hexagonal base for efficient heat dissipation

Single Zener Diodes Applications

• High power voltage regulation circuits
• Power supply protection systems
• Industrial equipment requiring radiation hardness

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix required, as the 'A' designation indicates +/- 10% Zener voltage tolerance. Confirm polarity requirements; standard units have anode-to-case polarity, while reverse polarity requires an 'R' suffix. Ensure adequate mounting hardware and heat sinking are specified to maintain case temperatures below 75°C for full 50 W power dissipation capability.

Single Zener Diodes Selection Notes

Select this component when high power handling and radiation hardness are critical. The 1N3341A offers a 105 V regulation point with significant current capacity. Consider the DO-5 package constraints for mechanical integration. Verify that the application can accommodate the required thermal management to prevent derating above 75°C case temperature.

Single Zener Diodes Part Context

This part is manufactured by Microsemi, now part of Microchip Technology, under the Scottsdale Division. It falls within the broader family of 50 Watt Zener Diodes, which includes types from 1N3305 to 1N3350B and 1N4549B to 1N4556B. These devices are designed for applications demanding high power dissipation and reliable voltage reference in demanding industrial or military contexts.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 105 V Zener diodes in the DO-5 package with comparable 50 W power ratings. Check for matching thermal resistance and tolerance specifications. Military qualified versions such as JAN1N3341A or JANTX1N3341A may be used if higher screening levels are required.
