Procurement Notes
Verify the specific suffix RB against official Microchip documentation to confirm exact qualification levels such as JAN, JANTX, or JANTXV. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm that the package type matches the required TO-204AD specifications for your assembly process.
Selection Notes
Select this component when a 200 V Zener voltage with 50 W power dissipation is required. Consider the TO-204AD package size for adequate heat sinking capabilities. Evaluate the maximum impedance value to ensure it meets the precision requirements of your voltage reference design. Verify that the operating temperature range aligns with your system's environmental constraints.
Part Context
This part is part of the broader 1N28xx series of 50 Watt Zener diodes manufactured by Microchip Technology. These devices are widely used in power electronics where high voltage regulation stability is critical. The series covers a range of voltages from 3.9 V to 200 V, providing designers with versatile options for various power supply architectures.
Replacement Considerations
Cross-reference with other manufacturers' 50 W Zener diodes rated at 200 V in TO-204 packages. Verify electrical parameters including Zener voltage tolerance, impedance, and power dissipation before substitution.
