Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the B280Q-13-F are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 80 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 790 mV @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 7 µA @ 80 V
• Capacitance @ Vr, F: 75 pF @ 4V, 1MHz

Mechanical Parameters:

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C to 150°C

Parts are classified as substitutes when all electrical parameters and mechanical specifications match the main part exactly. Packaging compatibility and thermal operating range must be identical to ensure direct replacement capability in circuit designs.
