Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 10 A
• Voltage - Forward (Vf) (Max) @ If: 600 mV @ 10 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 100 µA @ 40 V
• Technology: Schottky

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Supplier Device Package: D2PAK

Compliance Criteria:

• RoHS Status: ROHS3 Compliant

The MBRB1040-TP meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent. The substitute part maintains identical voltage, current, and thermal characteristics while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

MBRB1040-TP is the qualified substitute for SBLB1040-TP based on the following factors:

Electrical Compatibility: The MBRB1040-TP maintains identical electrical specifications across all critical parameters: 40V reverse voltage rating, 10A average rectified current, 600mV forward voltage drop at 10A, fast recovery switching characteristics, and 100µA reverse leakage current. These parameters ensure direct functional equivalence in circuit applications.

Mechanical Compatibility: Both parts utilize identical D2PAK surface mount packaging (TO-263-3, TO-263AB), enabling direct PCB footprint compatibility without layout modifications.

Compliance Status: The MBRB1040-TP carries ROHS3 compliance certification, matching the environmental regulatory requirements of the original part.

Product Status Advantage: The MBRB1040-TP holds active product status, providing assured long-term availability and supply chain continuity. The SBLB1040-TP obsolete classification creates procurement risk for future production requirements.

Temperature Range Enhancement: The MBRB1040-TP operating temperature range (-65°C ~ 150°C) exceeds the SBLB1040-TP specification (-40°C ~ 125°C), providing expanded thermal operating margin for demanding applications.
