Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZLLS2000TA-2477 is based on electrical parameter equivalence and package compatibility. The primary substitute, ZLLS2000TA, shares all critical electrical specifications: 40 V reverse voltage rating, 2.2 A average rectified current, 540 mV forward voltage drop at 2 A, 6 ns reverse recovery time, and identical thermal characteristics. Both components utilize Schottky technology and Surface Mount assembly methods.

The substitution is valid based on the following key parameters:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 2.2 A
• Voltage - Forward (Vf) (Max) @ If: 540 mV @ 2 A
• Reverse Recovery Time (trr): 6 ns
• Current - Reverse Leakage @ Vr: 40 µA @ 30 V
• Capacitance @ Vr, F: 65 pF @ 30V, 1MHz
• Operating Temperature - Junction (Max): 150°C
• Package / Case: SOT-23-6
