Substitute Part Grouping Explanation

Substitution of the P6SMB150CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 128V
• Voltage - Breakdown (Min): 143V
• Voltage - Clamping (Max) @ Ipp: 207V
• Current - Peak Pulse (10/1000µs): 2.9A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Bidirectional Channels: 1
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The P6SMB150CAHM3_B/I is identified as the manufacturer-recommended substitute. Both parts belong to the same P6SMB TransZorb® series and maintain identical electrical and mechanical specifications. The primary distinction is product status: the substitute part is Active, whereas the original part is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB150CAHM3_B/I is the direct equivalent substitute for the obsolete P6SMB150CAHM3_A/I. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical performance, thermal characteristics, and mechanical compatibility.

Selection of the P6SMB150CAHM3_B/I is supported by:

• Identical voltage and current ratings across all specified parameters
• Matching automotive-grade classification and AEC-Q101 qualification
• Identical surface mount package (DO-214AA, SMB) for direct PCB compatibility
• ROHS3 compliance and equivalent moisture sensitivity rating
• Active product status ensuring ongoing availability and supply chain support

No design modifications, PCB layout changes, or thermal management adjustments are required when transitioning from the obsolete part to the substitute.
