BYD37J Controlled Avalanche Surface Mount Rectifier

BYD37J is a fast soft-recovery controlled avalanche rectifier in a hermetically sealed SOD87 glass surface-mount package. It is rated for 600 V repetitive peak reverse voltage. The BYD37 series specifies up to 1.5 A average forward current under its stated tie-point condition, along with glass passivation, low leakage current, and controlled avalanche capability. This combination suits designs that need a compact rectifier with defined reverse-voltage and recovery behavior. Use the thermal and current limits when reviewing an existing circuit, especially where recovery or surge conditions matter. Match the package and electrical ratings carefully before replacing another diode. For maintenance or procurement, retain the complete identifier to prevent confusion with another voltage grade.
