BYW27-800

Overview

The BYW27-800 is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features an 800 V reverse voltage rating and supports a continuous forward current of 1 A. The component utilizes a DO-41 through-hole package and operates within a temperature range up to +175°C. Key electrical specifications include a maximum surge current of 30 A, a forward voltage of 1.1 V, and a reverse leakage current of 5 µA.

Feature Summary

• High thermal stability with a maximum junction temperature of +175°C
• Robust surge current handling capability for transient protection
• Standard recovery characteristics suitable for general-purpose rectification

Applications

• 50/60 Hz power supply rectification
• Polarity protection circuits
• General-purpose DC rectification

Procurement Notes

Verify the specific manufacturer datasheet for complete electrical limits and mechanical drawings. Confirm compliance with RoHS and REACH regulations prior to integration. Ensure the DO-41 through-hole package matches the target PCB footprint and assembly requirements.

Selection Notes

Select this component when high-temperature operation up to 175°C is required alongside standard 800V blocking capabilities. The DO-41 package offers reliable through-hole mounting for applications where surface-mount options are unsuitable or mechanical stress is a concern.

Part Context

This device belongs to the standard recovery rectifier category from Diotec Semiconductor. It is designed for general-purpose AC-to-DC conversion tasks in industrial and consumer electronics, providing a balance of voltage rating and current capacity in a traditional axial leaded form factor.

Replacement Considerations

Cross-reference with other DO-41 packaged 800V 1A rectifiers such as the 1N5408 series variants. Verify that substitute components meet the same +175°C maximum operating temperature and surge current specifications.
