1N5308 TR TIN/LEAD

Overview

The Central Semiconductor Corp 1N5308 TR TIN/LEAD is a silicon planar Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 5.1 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW at an ambient temperature of 25°C. It utilizes the DO-35 axial leaded package, suitable for through-hole mounting. The component operates within a junction temperature range of -65°C to +200°C. The 'TR' suffix indicates tape and reel packaging, while 'TIN/LEAD' specifies the terminal finish composition.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation performance
• Provides precise voltage reference capabilities with tight tolerance specifications
• Features high thermal stability with an extended operating junction temperature range up to 200°C
• Designed for through-hole assembly using standard axial leaded configurations

Applications

• Voltage regulation in low-power electronic circuits
• Precision voltage reference sources for analog signal processing
• Overvoltage protection stages in sensitive input lines
• Clamping applications in switching power supplies

Procurement Notes

Verify the specific ordering suffixes against manufacturer documentation to confirm packaging type and terminal finish. The 'TR' designation typically denotes tape and reel packaging, which differs from bulk or box quantities. Confirm RoHS compliance status and material declarations directly with the supplier, as tin/lead finishes may impact environmental regulatory adherence for specific end-use markets.

Selection Notes

Select this component when a 5.1 V Zener reference is required with moderate current handling capabilities. Ensure the circuit design accounts for the 500 mW power dissipation limit and derating requirements at elevated ambient temperatures. Verify that the DO-35 package dimensions align with the PCB footprint constraints and that the axial lead configuration fits the intended mechanical assembly process.

Part Context

This part belongs to the 1N53xx series of axial leaded Zener diodes manufactured by Central Semiconductor Corp. The series offers various voltage options ranging from low voltages to higher breakdown values, all sharing similar physical package characteristics and power ratings. The 1N5308 specifically targets the 5.1 V segment of this lineup, providing a standardized solution for common voltage reference needs in discrete semiconductor applications.

Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged 5.1 V Zener diodes with 500 mW ratings. Verify electrical parameters such as impedance, leakage current, and thermal resistance match the original design requirements. Ensure pinout compatibility and mechanical dimensions are identical for direct substitution without PCB modifications.
