1N3342B

Single Zener Diodes Overview

The Microchip Technology 1N3342B 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 110 V at a test current of 110 mA. The device features a maximum dynamic impedance of 30 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 at a case temperature below 75°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the specific order matches the required polarity, as standard units feature an anode-to-case connection. Confirm the tolerance suffix 'B' aligns with the necessary voltage accuracy. Ensure mounting hardware accommodates the DO-5 package hexagonal stud dimensions and thread specifications for proper installation.

Single Zener Diodes Selection Notes

Select this component when applications demand high power dissipation capabilities up to 50 watts. Consider the DO-5 package size and stud mounting requirements for mechanical integration. Evaluate the thermal resistance and derating curves to ensure adequate heat sinking is provided for sustained operation above 75°C case temperature.

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 ranges and are available in various military screening levels including JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/358 standards.

Single Zener Diodes Replacement Considerations
