Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSRD620CTRG is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Diode Configuration: 1 Pair Common Anode
• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io) (per Diode): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 3 A
• Reverse Recovery Time (trr): 75 ns
• Current - Reverse Leakage @ Vr: 1 µA @ 200 V

Mechanical Parameters (Non-Negotiable):

• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount

Compliance Parameters:

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

Substitute parts must maintain identical electrical performance and physical form factor to ensure direct replacement without circuit redesign or PCB layout modification.
