Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FEPE16AT-E3/45 are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io) (per Diode): 16 A
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Operating Temperature - Junction: -55°C ~ 150°C
• Package / Case: TO-220-3
• Mounting Type: Through Hole

Allowable Parameter Variations:

• Voltage - Forward (Vf) (Max) @ If: Within standard rectifier diode specifications
• Reverse Recovery Time (trr): Within fast recovery classification
• Current - Reverse Leakage @ Vr: Within acceptable leakage parameters
• Packaging format (tube vs. bulk)
• Product status (active vs. obsolete)

Substitute parts must maintain identical diode configuration, voltage rating, current rating, package type, and mounting method to ensure direct functional replacement without circuit redesign.
