BYV34-400.127 is part of NXP's line of BYV34 Fast Recovery Rectifiers. This rectifier is housed in a 4-pin, IP000 package and is ideal for use with power supplies, battery chargers, and other higher-powered applications where superior heat dissipation is required. This rectifier has a maximum repetitive peak inverse voltage (VRRM) of 400V and a maximum average forward rectified current (IF(AV)) of 3.0A. It has a recovery time of just 4.0µs, making it well-suited for use in heavily loaded power circuit designs.
