1N5418TR

Overview

The Vishay 1N5418TR is a fast avalanche Sinterglass diode housed in an SOD-64 package. It features a repetitive peak reverse voltage of 400 V and an average forward current rating of 3 A. The device exhibits a maximum forward voltage of 1.1 V at 3 A and 1.5 V at 9 A, with a reverse recovery time of up to 100 ns. It supports a peak forward surge current of 100 A and operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

• Hermetically sealed glass passivated junction for high reliability
• Soft recovery characteristics suitable for fast rectification
• High pulse current capability with low reverse leakage current

Applications

• Fast rectification circuits
• High-reliability power conversion systems
• Applications requiring soft recovery performance

Procurement Notes

Verify the ordering code matches the specific tape and reel configuration required for automated assembly processes. Confirm that the SOD-64 package dimensions align with the designated footprint on the printed circuit board. Ensure compliance with material categorization standards as defined by the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when a hermetically sealed, fast-recovery diode with a 400 V blocking voltage is required. The SOD-64 package provides a compact form factor compared to traditional axial leads. Consider the thermal resistance characteristics and lead length requirements to ensure adequate heat dissipation under continuous operating conditions.

Part Context

This part belongs to the 1N5417/1N5418 series of fast avalanche Sinterglass diodes manufactured by Vishay Semiconductors. The series utilizes voidless-glass construction to ensure durability in demanding environments. The 1N5418 variant specifically addresses applications requiring higher reverse voltage tolerance while maintaining fast switching speeds.

Replacement Considerations

Direct substitutes include the 1N5417 for lower voltage applications (200 V). Verify that any replacement maintains the SOD-64 package type and meets the same electrical ratings for reverse voltage and forward current.
