1N4385 BK TIN/LEAD

Overview

The 1N4385 BK TIN/LEAD is a silicon rectifier diode manufactured by Central Semiconductor Corp. It features a single element configuration housed in an axial DO-41 glass package with tin-lead terminal plating. The device supports a maximum average forward current of 1 A and withstands a maximum repetitive peak reverse voltage of 600 V. Designed for through-hole mounting, it operates within a temperature range suitable for general-purpose rectification applications.

Feature Summary

• Utilizes silicon material for reliable rectification performance
• Encased in a round glass body with long-form axial leads
• Features isolated case connection for secure mounting

Applications

• General-purpose power supply rectification
• Freewheeling circuits in inductive loads
• Low-frequency AC to DC conversion

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm terminal composition. Ensure the selected variant matches the required lead material specifications for your assembly process. Cross-reference the JEDEC package code DO-41 to guarantee mechanical compatibility with existing board layouts and tooling.

Selection Notes

Select this component when a robust glass-encapsulated rectifier is required for high-voltage isolation. The DO-41 package offers superior thermal stability compared to plastic equivalents. Confirm that the 600V rating aligns with the peak inverse voltage requirements of the target circuit design.

Part Context

This part belongs to the standard rectifier diode family produced by Central Semiconductor. It serves as a discrete semiconductor solution for converting alternating current to direct current. The DO-41 form factor is widely recognized in industrial electronics for its durability and standardized footprint.

Replacement Considerations

Direct substitutes include other 1A 600V DO-41 rectifiers such as the 1N4007 series or equivalent parts from Vishay like the 1N4385GP, provided pinout and electrical ratings match.
