1N5530/TR

Overview

The 1N5530/TR is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 10 V and operates with a test current of 1 mA. The device has a maximum power dissipation of 500 mW and exhibits a Zener impedance of 60 Ohms. It is housed in a DO-35 axial through-hole package. The component supports an operating temperature range from -65°C to +175°C junction temperature.

Feature Summary

• Provides stable voltage regulation at a nominal 10 V level under specified test conditions.
• Capable of handling up to 500 mW of power dissipation within the rated thermal limits.
• Constructed with a glass passivated junction for reliable performance in harsh environments.

Applications

• Voltage reference circuits requiring precise 10 V stabilization.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications in signal processing paths.

Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as it may vary by production batch. Ensure the supplier provides valid traceability documentation for the Microchip manufacturing origin. Check for any specific handling requirements related to the axial leaded glass package during assembly.

Selection Notes

Select this component when a 10 V Zener voltage with 500 mW power rating is required in a through-hole configuration. Consider the 60 Ohm impedance value for dynamic regulation needs. Evaluate the wide operating temperature range for high-temperature industrial applications. Compare against standard commercial grades if military or aerospace qualification is not necessary.

Part Context

This part belongs to the 1N553x series of Zener diodes produced by Microchip Technology. The series offers various voltage options within the same DO-35 package form factor. The /TR suffix denotes a specific packaging format intended for automated insertion processes, distinguishing it from bulk packaged variants.

Replacement Considerations

Direct substitutes include other manufacturers' 1N5530 equivalents meeting the 10 V, 500 mW, DO-35 specifications. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with JANTX1N5530B-1 for qualified alternatives if higher reliability standards are required.
