• Features high reliability with superior lot-to-lot consistency
• Constructed with molded plastic housing rated UL 94V-0 flammability

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Power supply regulation

Procurement Notes

Verify the specific manufacturer for the exact part number, as Central Semiconductor lists this component as End of Life with CZ5368B as the designated replacement. Confirm RoHS compliance status and plating options (Pb-free or Tin/Lead) directly with authorized distributors or alternative manufacturers before procurement.

Selection Notes

Select based on the required 5W power dissipation and 47V breakdown voltage. Ensure the DO-15 package size fits the design constraints. Verify that the operating temperature range meets the application's thermal requirements and confirm the availability of compliant alternatives due to the original manufacturer's discontinuation notice.

Part Context

This component belongs to the 1N53xx series of 5-watt Zener diodes manufactured by Central Semiconductor. These devices are designed for general-purpose voltage regulation applications requiring higher power handling capabilities compared to lower wattage variants. The series offers various voltage options within the specified range.

Replacement Considerations

Central Semiconductor officially lists CZ5368B as the replacement for 1N5368B.
