1N5302 TR PBFREE

Overview

The 1N5302 TR PBFREE is a silicon rectifier diode manufactured by Central Semiconductor Corp. It features a maximum average forward rectified current of 1.0 A and a repetitive peak reverse voltage of 200 V. The device exhibits a maximum DC forward voltage drop of 1.1 V at the rated current and a non-repetitive peak forward surge current capability of 30 A. Electrical characteristics include a maximum RMS reverse voltage of 140 V and a maximum reverse leakage current of 5.0 µA at rated voltage. The component operates within a junction temperature range of -65°C to +175°C and is supplied in an axial DO-41 package.

Feature Summary

• High thermal stability with a maximum operating junction temperature of 175°C
• Robust surge current handling capability for transient protection applications
• Low forward voltage drop for improved power efficiency
• Standard axial leaded construction for through-hole mounting

Applications

• General-purpose rectification in AC-to-DC power supply circuits
• Polarity protection in DC power input stages
• Freewheeling diodes in inductive load switching circuits
• Bypass diodes in battery charging systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details, as standard designations may vary between bulk and tape-and-reel configurations. Ensure compliance with RoHS directives if required by the end application. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a 1.0 A continuous current rating and 200 V blocking voltage are required for through-hole implementations. Evaluate the thermal management requirements to ensure the junction temperature remains within the specified 175°C limit under worst-case operating conditions. Consider the forward voltage drop impact on overall system efficiency compared to alternative technologies.

Part Context

This part belongs to the 1N53xx series of high-power silicon rectifiers produced by Central Semiconductor. The series is characterized by robust construction suitable for industrial and commercial power conversion applications. The 'TR' designation typically indicates reel packaging, while 'PBFREE' confirms the absence of halogenated flame retardants and lead in accordance with environmental standards.

Replacement Considerations

Equivalent parts from other manufacturers must match the 1.0 A current rating, 200 V reverse voltage, and DO-41 package dimensions. Verify that substitute components meet or exceed the 175°C junction temperature rating and similar forward voltage specifications to maintain circuit performance integrity.
