BY4

Overview

The BY4 is a standard recovery high voltage rectifier diode manufactured by Diotec Semiconductor. It features a repetitive peak reverse voltage (VRRM) of 4000 V and a maximum forward current (IFAV) of 1.0 A. The device exhibits a peak forward surge current (IFSM) rating of 30 A and a typical reverse recovery time (trr) of approximately 1500 ns. Operating within a junction temperature range of -50°C to +150°C, it utilizes an axial package with dimensions of Ø 7.3 x 22 mm.

Feature Summary

High voltage capability up to 16 kV across the series
Designed for high creepage and clearance distances
Compliant with RoHS exemption 7a-I, REACH, and Conflict Minerals regulations

Applications

High voltage rectification at 50/60 Hz
Commercial grade power supply circuits

Procurement Notes

Verify that the specific procurement order matches the exact part number BY4 to ensure correct voltage ratings. Confirm compliance requirements against RoHS exemption 7a-I if applicable to your manufacturing standards. Ensure storage and handling procedures account for the commercial grade classification and specified thermal limits during assembly.

Selection Notes

Select this component when designing circuits requiring high voltage isolation and standard recovery characteristics. Consider the 4000 V reverse voltage rating and 1.0 A continuous current capacity. Evaluate the thermal resistance and derating curves for ambient temperatures exceeding 25°C to maintain reliability within the specified operating junction temperature range.

Part Context

This component belongs to the BY4 through BY16 series of standard recovery high voltage rectifier diodes produced by Diotec Semiconductor. The series covers voltages from 4 kV to 16 kV with varying current ratings. These devices are engineered for robust performance in commercial applications requiring reliable high-voltage rectification under standard industrial conditions.
