Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF2035CT-E3/45 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Diode configuration must remain 1 Pair Common Cathode
• Technology must be Schottky
• Voltage - DC Reverse (Vr) rating must equal or exceed 35 V
• Current - Average Rectified (Io) per diode must equal or exceed 10 A
• Forward voltage (Vf) characteristics must be compatible at rated current
• Speed classification must maintain Fast Recovery performance
• Reverse leakage current must be within acceptable limits

Mechanical Compatibility Criteria:

• Mounting type must be Through Hole
• Package must be TO-220-3 Full Pack with isolated tab
• Operating temperature range must encompass -65°C to 150°C

The MBRF2045CT-E3/45 qualifies as a direct substitute because it maintains identical diode configuration, technology, forward voltage characteristics, speed classification, mounting type, and package specification. The elevated voltage rating (45 V versus 35 V) provides enhanced voltage margin while preserving all other electrical and mechanical parameters.
