1N5305 TR PBFREE

Overview

The 1N5305 TR PBFREE is a silicon planar power Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 75 V with a tolerance of ±5% and a maximum power dissipation of 5 W. The device utilizes an axial leaded DO-201AE package, suitable for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 64 V and a test current of 28 mA. It operates within a junction temperature range of -65°C to +200°C and complies with RoHS standards.

Feature Summary

• High power dissipation capability of 5 W in a robust axial package
• Wide operating junction temperature range up to 200°C
• Low reverse leakage current for stable performance
• Planar technology construction for reliability

Applications

• Voltage regulation in high-power circuits
• Overvoltage protection for sensitive components
• Reference voltage sources in industrial equipment
• Clamping applications in power supplies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm packaging details such as tape and reel specifications. Ensure that the procurement documentation explicitly states compliance with RoHS directives and confirms the absence of restricted substances. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when a 75 V Zener voltage with 5 W power handling is required in a through-hole configuration. Consider the DO-201AE package dimensions for PCB layout compatibility. Evaluate thermal management requirements given the 5 W dissipation rating and ensure the operating environment stays within the specified -65°C to +200°C junction temperature range for optimal longevity.

Part Context

This part belongs to the standard 1N53xx series of high-power Zener diodes produced by Central Semiconductor. These devices are designed for general-purpose voltage regulation and protection applications where higher power handling than standard small-signal diodes is necessary. The series offers various voltage options within the same mechanical footprint, facilitating design flexibility across different power supply architectures.

Replacement Considerations

Equivalent parts from other manufacturers must match the 75 V nominal voltage, 5 W power rating, and DO-201AE package. Verify that substitute components meet or exceed the 5 µA reverse leakage specification and support the same 200°C maximum junction temperature. Confirm RoHS compliance if environmental regulations apply to the end product.
