Substitute Part Grouping Explanation

Substitution of the BTS428L2NT is determined by strict equivalence across the following critical parameters:

• Output Configuration: High Side
• Output Type: N-Channel
• Number of Outputs: 1
• Ratio - Input:Output: 1:1
• Voltage - Load Range: 4.75V ~ 41V
• Current - Output (Max): 5.8A
• Rds On (Typ): 50mOhm
• Input Type: Non-Inverting
• Interface: On/Off
• Fault Protection: Current Limiting (Fixed), Over Temperature, Over Voltage
• Features: Status Flag
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Package / Case: TO-252-5, DPAK (4 Leads + Tab), TO-252AD
• Mounting Type: Surface Mount

The BTS428L2ATMA1 meets all these critical parameters and serves as a parametric equivalent substitute for the obsolete BTS428L2NT.
