1N3350RB

Single Zener Diodes Overview

The Microchip Technology 1N3350RB is a high-power 50 W Zener diode within the JEDEC registered 1N3305 through 1N3350B series. It provides voltage regulation with a nominal Zener voltage of 160 V and a tolerance of ±5%. The device features internal solder bond construction and is hermetically sealed in an industry-standard DO-5 (DO-203AB) package with a hexagonal stud. It operates at a maximum DC power dissipation of 50 watts when the case temperature is below 75°C, with thermal resistance from junction to base at a maximum of 2.0°C/W.

Single Zener Diodes Feature Summary

• Hermetically sealed welded metal and glass construction for durability
• Internal solder bond design ensuring robust electrical connections
• Reverse polarity configuration with cathode connected to the case
• Inherently radiation hard characteristics suitable for harsh environments

Single Zener Diodes Applications

• High-power voltage regulation circuits
• Military and aerospace electronic systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the reverse polarity designation and tolerance level. Confirm that the required military qualification levels are available if needed for your application. Ensure proper mounting hardware and heat sinking are selected to maintain case temperatures within specified limits during operation.

Single Zener Diodes Selection Notes

Select this component for applications requiring high power dissipation capabilities up to 50 watts. Consider the thermal management requirements carefully, as power must be derated above a case temperature of 75°C. Verify that the system can accommodate the physical dimensions and mounting style of the DO-5 package with its hexagonal stud configuration.

Single Zener Diodes Part Context

This part belongs to the 1N3305 through 1N3350B series of 50 W Zener diodes manufactured by Microchip Technology's Scottsdale Division. These devices are designed for high-reliability applications and are also available in JAN, JANTX, and JANTXV military qualifications. The series covers a broad range of voltages from 3.9 V to 200 V, providing versatile options for various power regulation needs.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 50 W Zener diodes with similar voltage ratings and package styles. Check for availability in JAN, JANTX, or JANTXV grades if higher screening levels are required. Ensure any replacement maintains the same reverse polarity configuration and thermal resistance characteristics.
