1N5293 TR TIN/LEAD

Overview

The 1N5293 TR TIN/LEAD is a Zener diode manufactured by Central Semiconductor Corp, designed for voltage regulation and reference applications. It features a nominal Zener voltage of 6.8 V with a power dissipation rating of 500 mW. The device utilizes a DO-35 axial through-hole package and operates within a junction temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 10 V and a Zener impedance of 15 Ohms. The component is supplied in tape and reel packaging and complies with RoHS3 standards.

Feature Summary

• Provides stable voltage regulation with a nominal 6.8 V Zener breakdown voltage
• Supports high-temperature operation up to a junction temperature of +200°C
• Utilizes a compact DO-35 axial leaded package suitable for through-hole mounting

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in low-power electronic systems
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm compliance requirements and packaging configuration. Confirm that the tin/lead terminal finish aligns with assembly process specifications. Cross-reference the datasheet revision date to ensure parameter accuracy. Validate RoHS3 status if environmental restrictions apply to the final product design.

Selection Notes

Select this component when a 6.8 V reference is required in a small axial package. Ensure the circuit current does not exceed limits derived from the 500 mW power dissipation rating. Verify that the operating environment remains within the specified -65°C to +200°C junction temperature range. Consider the 15 Ohm impedance value for dynamic regulation requirements.

Part Context

This part belongs to the 1N52xx series of glass-passivated Zener diodes produced by Central Semiconductor Corp. The series covers a wide voltage range using standardized DO-35 and DO-41 packages. The 1N5293 variant specifically addresses the 6.8 V segment, offering reliable performance for general-purpose regulation tasks in industrial and consumer electronics.

Replacement Considerations

Equivalent parts include the 1N5293B from other manufacturers such as onsemi or Taiwan Semiconductor Corporation. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement device meets the same 500 mW power dissipation and 6.8 V tolerance specifications.
