Nexperia 400V/650V DPAK Recovery Rectifiers

Introduction

Nexperia 400V/650V DPAK Recovery Rectifiers are high-performance power diodes designed for efficient switching and rectification in demanding power-electronic circuits. Available with voltage ratings from 400 V to 650 V and current capabilities from 4 A to 15 A, these devices combine robust power handling with fast recovery characteristics in a compact DPAK Real-2-Pin package.

Part Description

These Nexperia recovery rectifiers are hyperfast and ultrafast diodes intended for applications where switching performance is important. Their fast and smooth reverse-recovery behavior helps reduce switching losses, voltage ringing, and electromagnetic interference compared with slower conventional rectifiers.

The devices also feature low leakage current and are housed in a DPAK Real-2-Pin package, supporting compact board layouts and practical thermal management. Their combination of high reverse-voltage capability, moderate-to-high current ratings, and efficient recovery performance makes them suitable for both high-frequency power conversion and inductive-load protection.

Key characteristics include:

• Reverse-voltage ratings from 400 V to 650 V
• Forward-current ratings from 4 A to 15 A
• Hyperfast and ultrafast reverse-recovery performance
• Smooth recovery behavior for lower switching noise
• Low leakage current
• DPAK Real-2-Pin surface-mount package
• Suitable for high-efficiency power switching designs
