3KBP08M-E4/51

Bridge Rectifier Overview

The Vishay 3KBP08M-E4/51 is a glass-passivated single-phase bridge rectifier in the KBPM case style. It provides a maximum average forward output rectified current of 3.0 A at an ambient temperature of 55 °C and supports a peak forward surge current of 80 A. The device features a maximum repetitive peak reverse voltage of 800 V, with a maximum RMS voltage of 560 V and a maximum DC blocking voltage of 800 V. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.05 V per diode at 3.0 A and a maximum DC reverse current of 5 µA at rated voltage. The component operates within a junction and storage temperature range of -55 to +150 °C.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The /51 designation indicates delivery in anti-static PVC trays with a base quantity of 600 units. Confirm that the E4 suffix aligns with required lead-free material specifications and RoHS compliance standards for the intended manufacturing process.

Bridge Rectifier Selection Notes

Select this component when an 800 V rating is required for single-phase rectification with a 3 A continuous load capacity. Ensure the thermal design accommodates the specified thermal resistance values from junction to ambient and junction to lead. Verify that the operating environment remains within the -55 to +150 °C temperature range to maintain performance reliability.

Bridge Rectifier Part Context

This part belongs to the 3KBP005M through 3KBP08M series of glass-passivated bridge rectifiers manufactured by Vishay General Semiconductor. All variants share the same KBPM case style and electrical architecture, differing primarily in their maximum repetitive peak reverse voltage ratings which range from 50 V to 800 V across the product line.
