BYD37D Glass Surface Mount Avalanche Rectifier

BYD37D is a fast soft-recovery controlled avalanche rectifier supplied in the SOD87 glass surface-mount outline. It is rated for 200 V repetitive peak reverse voltage. The BYD37 series specifies up to 1.5 A average forward current under the stated tie-point condition and uses glass-passivated construction with controlled avalanche energy capability. Its cylindrical package is hermetically sealed, supporting a compact surface-mount footprint for rectification duties. Engineers should compare reverse voltage, forward-current conditions, recovery requirements, and thermal limits before making a substitution. Use the exact part number when maintaining equipment built around this diode, since other BYD37 variants carry different voltage ratings. Confirm circuit requirements before installation.
