1N4384 BK PBFREE

Single Diodes Overview

The 1N4384 BK PBFREE is a general-purpose rectifier diode manufactured by Central Semiconductor Corp. It features a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage of 400 V. The device utilizes a DO-41 (DO-204AL) axial through-hole package. Key electrical specifications include a maximum DC reverse voltage of 400 V, a forward voltage drop of 1.1 V at 1 A, and a non-repetitive peak forward surge current rating of 30 A for an 8.3 ms single half-sine-wave impulse.

Single Diodes Feature Summary

• Standard silicon rectification with high reverse voltage blocking capability
• Robust construction in a lead-free, RoHS-compliant axial package
• Designed for general-purpose power supply and conversion applications

Single Diodes Applications

• AC to DC bridge rectifier circuits
• Power supply input stages
• General-purpose polarity protection

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance status and terminal finish. The 'BK' designation typically indicates black band marking, while 'PBFREE' confirms lead-free composition. Ensure the procurement specification matches the required voltage and current ratings for the target circuit design.

Single Diodes Selection Notes

Select this component when a 1 A continuous current rating and 400 V reverse voltage are required in an axial package. Consider thermal derating requirements for ambient temperatures exceeding standard test conditions. Verify that the DO-41 footprint aligns with the printed circuit board layout constraints.

Single Diodes Part Context

This part belongs to the 1N4xxx series of general-purpose rectifiers from Central Semiconductor. The series offers various voltage ratings ranging from 200 V to 1000 V within the same mechanical form factor. The 1N4384 specifically provides a 400 V rating, bridging the gap between lower voltage 1N4001 variants and higher voltage options like the 1N4007.

Single Diodes Replacement Considerations

Direct functional equivalents include the 1N4004 and 1N5394. These parts share identical 1 A current and 400 V voltage ratings. Verify pinout compatibility and package dimensions before substitution.
