• Clamping applications in signal processing paths.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'BK TIN/LEAD' against the manufacturer's latest datasheet to confirm lead content and packaging format. Ensure the DO-35 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status if restricted substances are prohibited in your assembly process. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Single Zener Diodes Selection Notes

Select this component when a 13 V Zener voltage is required with moderate power handling capabilities. The DO-35 package suits standard through-hole assembly processes. Consider the 500 nA leakage current specification for low-power circuit designs. Evaluate the thermal management needs given the 500 mW dissipation rating and high-temperature capability.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of Zener diodes manufactured by Central Semiconductor. These devices are widely used in general-purpose electronics for voltage regulation and protection. The series offers various voltage options within the same DO-35 package family, allowing for design flexibility while maintaining consistent mechanical and thermal characteristics across different voltage ratings.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 13 V Zener voltage, 500 mW power rating, and DO-35 package. Verify that alternative manufacturers offer compatible tolerance and leakage current specifications. Ensure the replacement part supports the same operating temperature range and mounting style.
