Overview
The Microchip Technology 1N2824RB is a single silicon Zener diode with a nominal breakdown voltage of 33 V and a tolerance of ±5%. It features a maximum power dissipation of 50 W at 25°C. The device utilizes an internal solder bond construction within a hermetically sealed metal flange mount package (TO-204AD/TO-3). It operates within a temperature range of -65 °C to 175 °C, with the case connected to the cathode terminal.
Feature Summary
- Hermetically sealed welded metal package for environmental protection
- Internal solder bond construction for reliability
- High power handling capability suitable for robust regulation
Applications
- High-power voltage regulation circuits
- Industrial equipment requiring ruggedized components
- Military and aerospace electronic systems
Procurement Notes
Verify that the specific order includes the 'RB' suffix to ensure the TO-204AD (TO-3) flange mount package configuration. Confirm compliance requirements as the component may not be RoHS compliant depending on the manufacturing batch. Ensure thermal management solutions are adequate for the 50 W power rating during operation.
Selection Notes
Select this component when a high-power, hermetically sealed Zener diode is required for critical applications. The 33 V breakdown voltage and 50 W rating distinguish it from lower-power variants. The TO-3 package facilitates direct mounting to heat sinks or chassis for efficient thermal dissipation in demanding environments.
Part Context
This part belongs to the JEDEC registered 1N2804 through 1N2846B series of Zener diodes manufactured by Microchip Technology. These components are designed for high-reliability applications, often serving as voltage references or surge suppressors in harsh operating conditions where standard plastic packages would fail.
Replacement Considerations
Equivalent parts include other manufacturers' 1N2824 variants with identical electrical specifications and TO-3 packaging. Verify pinout compatibility and thermal resistance characteristics before substitution.
