Substitute Part Grouping Explanation

Substitution of the VS-8CSH01-M3/87A is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io) (per Diode): 4 A
Voltage - Forward (Vf) (Max) @ If: 950 mV @ 4 A
Reverse Recovery Time (trr): 25 ns
Current - Reverse Leakage @ Vr: 2 µA @ 100 V
Operating Temperature - Junction: -65°C ~ 175°C

Mechanical Parameters:

Diode Configuration: 1 Pair Common Cathode
Package / Case: TO-277, 3-PowerDFN
Mounting Type: Surface Mount

Compliance Parameters:

RoHS Status: ROHS3 Compliant
