1N3341RB

Single Zener Diodes Overview

The Microchip Technology 1N3341RB 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 and a tolerance of ±5%. The device features reverse polarity, indicated by the 'R' suffix, connecting the cathode to the case. It operates within a junction temperature range of -65°C to +175°C and utilizes a hermetically sealed DO-5 (DO-203AB) package with an 11/16 inch hexagonal stud.

Single Zener Diodes Feature Summary

• Hermetically sealed welded metal and glass construction for durability
• Internal solder bond construction ensures mechanical stability
• Reverse polarity design connects the cathode directly to the mounting case
• Inherently radiation hard and non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• High power voltage regulation in industrial environments
• Protection circuits requiring robust thermal dissipation
• Military and aerospace applications utilizing MIL-PRF-19500/358 qualifications

Single Zener Diodes Procurement Notes

Verify that the specific order includes the 'R' suffix to confirm reverse polarity configuration, as standard units feature anode-to-case polarity. Confirm compliance requirements regarding RoHS status, as this component family may not meet current environmental directives. Ensure mounting hardware specifications align with the 1/4-28 thread requirement for the hexagonal stud interface.

Single Zener Diodes Selection Notes

Select this component when a 105 V regulation point is required with high power handling capabilities. The reverse polarity option is critical for designs where the circuit ground must connect to the mounting surface. Evaluate thermal management needs against the maximum DC power dissipation rating and derating curve above 75°C case temperature.

Single Zener Diodes Part Context

This part belongs to the 1N3305 through 1N3350B series of 50 Watt Zener diodes manufactured by Microchip Technology's Scottsdale Division. The series covers a broad voltage range from 3.9 V to 200 V. The 'B' suffix denotes a standard voltage tolerance of ±5%, while the 'R' suffix specifically indicates the reversed polarity configuration unique to this variant.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N3341B for standard polarity or military qualified variants such as JANTX1N3341B and JANTXV1N3341B. Verify that substitute components match the DO-5 package dimensions and thermal resistance characteristics.
