• Designed for use in stabilizing and clipping circuits
• Standard Zener voltage tolerance of ±10%

Applications

• High-power voltage regulation
• Circuit clipping applications

Procurement Notes

Verify the specific ordering suffix required for your application, such as PBFREE or TIN/LEAD, as these indicate plating options rather than functional changes. Confirm that the TR suffix aligns with your preferred packaging format. Cross-reference the manufacturer part number against official datasheets to ensure compliance with RoHS standards and environmental regulations before finalizing procurement.

Selection Notes

Select this component when a 5 W power rating and 9.1 V Zener voltage are required for robust voltage regulation. Ensure the circuit design accommodates the specified ±10% tolerance and the operating temperature limits. Verify that the DO-201 through-hole package fits the board layout constraints and thermal management requirements of the target application.

Part Context

This component belongs to the 1N53xx series of power Zener diodes manufactured by Central Semiconductor Corp. These devices are commonly used in industrial and commercial electronics where reliable voltage reference and protection are critical. The series provides various voltage options within the same physical footprint, simplifying inventory management for designers.
