1N3341B

Single Zener Diodes Overview

The Microchip Technology 1N3341B 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 105 V at a test current of 120 mA. The device features a maximum dynamic impedance of 25 Ohms and a typical temperature coefficient of 0.095 %/°C. It operates within a junction and storage temperature range of -65°C to +175°C, dissipating up to 50 watts when mounted on a heat sink below 75°C.

Single Zener Diodes Feature Summary

• Hermetically sealed welded metal and glass construction for durability
• Internal solder bond design ensuring structural integrity
• Standard polarity configuration with anode connected to the case
• Radiation hard characteristics suitable for harsh environments

Single Zener Diodes Applications

• High power voltage regulation circuits
• Industrial equipment requiring robust protection
• Military and aerospace systems utilizing MIL-PRF-19500/358 qualified variants

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for tolerance and polarity before ordering. Confirm that the application includes adequate mounting hardware and heat sinking to manage the 50 W power dissipation. Ensure the operating stud temperature remains below 75°C to maintain rated performance. Check for availability of military qualifications if required by the system specification.

Single Zener Diodes Selection Notes

Select this component for applications demanding high power handling in a ruggedized package. The DO-5 (DO-203AB) hexagonal stud mount facilitates direct thermal coupling to chassis or heatsinks. Consider the reverse polarity option if the circuit design requires the cathode to be connected to the case instead of the standard anode-to-case configuration.

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 designed for broad voltage regulation needs ranging from 3.9 V to 200 V. The series offers various tolerance options and military screening levels to support diverse industrial and defense electronics requirements.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 50 W Zener diodes in the DO-5 package with matching 105 V specifications. Verify thermal resistance and pinout compatibility, particularly regarding the standard anode-to-case polarity versus reverse polarity options.
