Substitute Part Grouping Explanation

Substitution of the P6SMB180CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 154V
• Voltage - Breakdown (Min): 171V
• Voltage - Clamping (Max) @ Ipp: 246V
• Current - Peak Pulse (10/1000µs): 2.4A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Package / Case: DO-214AA (SMB)
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The substitute part P6SMB180CAHM3_B/I maintains identical electrical specifications and mechanical compatibility. The primary distinction is product status: the substitute transitions from Obsolete to Active, ensuring ongoing availability and supply chain support.
