Substitute Part Grouping Explanation

Substitution eligibility for the DBL156G is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Peak reverse voltage must equal 800 V
• Current Rating: Average rectified current must equal 1.5 A
• Forward Voltage Drop: Maximum forward voltage at rated current must equal 1.1 V @ 1.5 A
• Reverse Leakage: Maximum reverse leakage current must equal 2 µA @ 800 V
• Operating Temperature Range: Must support -55°C to 150°C (TJ)
• Diode Configuration: Single-phase bridge rectifier topology
• Mounting Technology: Through-hole mounting required
• Package Format: 4-DIP (0.300", 7.62mm) package required

The DBL156GH meets all substitution criteria as a parametric equivalent, maintaining identical electrical performance specifications and mechanical compatibility with the original DBL156G.
