Substitute Part Grouping Explanation

Substitution of the VS-61CTQ035PBF is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 35 V
• Current - Average Rectified (Io) (per Diode): 30 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 1 mA @ 35 V
• Operating Temperature - Junction: -65°C to 175°C

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: TO-220-3

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part VS-61CTQ035-M3 meets all electrical, mechanical, and compliance requirements for direct substitution. The primary difference is product status: VS-61CTQ035-M3 is Active, whereas VS-61CTQ035PBF is Discontinued at DiGi Electronics.
